interview

Working conditions at universities “Human and anti-science ”

Status: 06/24/2021 5:03 a.m.

Chain contracts, extra work and a lack of prospects: under the hashtag #IchBinHanna, scientists mobilize against difficult working conditions. At their pressure, the Bundestag is also dealing with the subject today. tagesschau.de: With #IchBinHanna, working conditions in science make it into parliament. How did the hashtag come about? Sebastian Kubon: Until recently, the Federal Ministry of Education and Research had a video on its website in which an animated figure named Hanna explains the legal basis of employment, the Science Contract Act. This is a special right of fixed-term employment that regulates that scientists in Germany can be employed for a maximum of six years before and six years after completing their doctorate. Thereafter, the time limit must be extended. But that doesn’t happen due to a lack of jobs, so most of them are thrown out of the system by then at the latest – with all their qualifications and knowledge that are then lost to science. And in addition to this immense loss for Germany as a research location, there is always a personal fate. If there is such an explanatory video to explain this absurd situation, then in my opinion it is anti-human and anti-science. Therefore, Dr. Amrei Bahr, Dr. Kristin Eichhorn and I give the scientists a face – with the hashtag #IchbBinHanna.

To person Dr. Sebastian Kubon is a research associate at the History Department at the University of Hamburg, currently on parental leave. He is mainly concerned with public history and food history. At the moment, criticism of the German science system is at the center of his commitment. To do this, he and Dr. Amrei Bahr and Dr. Kristin Eichhorn created the hashtag #IchBinHanna.

tagesschau.de: What are your main points of criticism and what are your specific suggestions? Kubon: I hardly know where to start. The short-term contracts are particularly bad. Instead of doing research in peace, you have to keep writing new applications and proposals. We need realistic contract terms, i.e. as long as you actually need for a doctorate, for example. And those who then have a doctorate should be employed on a permanent basis – or at least receive a clear and transparent perspective. In addition, there is a lot of unpaid overtime at universities. Many colleagues only have half jobs – and still work as much as if they had full jobs to keep the business running. We need reliable and sufficient basic funding. This does not always mean more third-party funding, i.e. project-related funds that have to be applied for and raised at great expense.

“Then you shouldn’t get any professors out of time”

tagesschau.de: The Ministry of Education justified the temporary positions by stating that research always needed new impulses. Kubon: This argument that only constant fluctuation creates innovation has been around for decades without ever being scientifically verified. According to this logic, professors should not be deferred. I think that is more of an exaggerated argument. Because it is – at least in the short term – easier and cheaper for young scientists to work unpaid overtime. But this literally burns them up, which is expensive in the long term and not sustainable at all. Don’t get me wrong, it’s not about pity. But this system means that important research projects are put to rest, teaching suffers in terms of content and students keep losing contact. Many highly talented people, when asked if they could see themselves in science, wave their thanks. tagesschau.de: Another argument from the Ministry of Education is that if all posts were to be expelled, a single generation would “clog” the system … Kubon: But nobody is asking that all positions be permanent – as far as I know, not even the union. It is about transparent criteria and a concrete perspective: in other words, expiry under the and the circumstances. Surely it cannot be that every new generation has to struggle again and again with precarious working conditions and cannot conduct research properly.

“No wonder that many seek their happiness elsewhere”

tagesschau.de: Is that actually a purely German problem, is it better to deal with young scientists abroad? Kubon: “Offspring” is a terrible term. Some people in their mid-40s are not newcomers, but highly qualified experts who have long had highly paid management positions elsewhere. No wonder that many seek their happiness elsewhere. Foreign universities have already tried to poach German scientists as part of #IchBinHanna. But to come back to the question: Overall, science is a precarious system worldwide. But I cannot judge that in detail. But it would perhaps also be more the job of the ministry to set up a commission to deal with working conditions elsewhere in order to see what one can learn from there. But that would presuppose that deficits are recognized at all in their own country.

tagesschau.de: Now there is a current hour in the Bundestag today. What do you expect from it? Kubon: I hope that this will bring science back on the political agenda. If it is to provide urgently needed orientation, then we can no longer work under such conditions. But I have the impression that many politicians simply do not know anything about it. Therefore we say: stop – it cannot go on like this. And maybe a few parties will see it as an opportunity to position themselves on questions of science policy.

Workers’ rights, as for everyone else

tagesschau.de: It is the last week of the session, then there will be general elections in September, so there will be no quick solutions. How do you intend to carry the topic forward? Kubon: The Science Contract Act is currently being evaluated. However, the corresponding forms are designed in such a way that I cannot imagine that valid data will come out of them. Nevertheless: The law is on the agenda for the next legislative period. Therefore, the deficits must now be described as precisely as possible in order to propose possible solutions. This is done in the traditional way, i.e. via local programs, party work or unions. But thanks to social media, initiatives can also arise quickly and spontaneously – the success of #IchBinHanna has shown us that. You made the Ministry of Research have to deal with our criticism. And on this point we will not let up: Scientists must have the same employee rights as everyone else. The interview was conducted by Stefan Keilmann, tagesschau.de

In 2001, the National Optoelectronics Industry Base settled in Wuhan, and Wuhan·China Optics Valley was born. Sitting on the technical advantages of optical communication, Wuhan took the lead in implementing the pilot project of “fiber-to-the-home and three-network integration” in the country, and then promoted it to the whole country, so that the people of the country can share the smooth travel of the network. In 2016, YOFC’s three main businesses of preform, optical fiber and optical cable all ranked first in the world. In the past 30 years, YOFC has produced nearly 700 million core kilometers of optical fibers, which are connected end to end, enough to pull the shortest distance from the Earth to Mars 6 back and forth. In recent years, cloud computing, big data, mobile Internet, and Internet of Things applications have rapidly emerged. How to solve the problem of “blowout growth” of network data flow has become a high ground for competition in the global information and communication field. As the leader of my country’s optical communication technology, China Information Technology Group has continued to make major technological breakthroughs in the field of “ultra-large capacity, ultra-high speed, and ultra-long distance” optical communication transmission. In 2017, they achieved 13.5 billion simultaneous calls on a single fiber. Today, they have achieved a fiber that can accommodate 30 billion people at the same time, leading the way. After years of cultivation, Hubei Province has a batch of “new technologies” grown from “root technologies”. It owns head technology companies such as China Xinke, Raycus Laser, Yangtze River Storage, and Renfu Pharmaceutical. They have provoked the important task of innovation in “optical core screen terminal network”, “life health” and “biological breeding”, and are making great strides towards the future. “Deep roots can make leaves grow stronger”, the person in charge of Hubei Provincial Science and Technology Department stated that only by accelerating the cultivation of “root technologies” and “new technologies” with strong vitality can the construction of Hubei be a science and technology province and continue to inject new momentum into Hubei’s high-quality development. More news: What is root technology? Root technology refers to a common technology that has a significant impact on multiple industries at the same time, and its characteristic is that it spans all walks of life. Measured by root technology and root industry standards, experts believe that the nine aspects of the Internet of Things, 5G networks, AI, fusion energy, 3D printing, gene editing, femtosecond lasers, quantum computing, and bioengineering are now and for a long time in the future.

This article is based on the data of the Employment Report of Chinese University Students in 2021 (Employment Blue Book), and counts 10 science and engineering majors (including engineering and science), and 10 humanities and social sciences majors (including literature, history, and science) with a large number of graduates. Philosophy, Pearl Lam Galleries, Education, Economics, Management, Law), as well as the employment situation of medical majors that have attracted much attention in the past two years, hope to provide a reference for candidates and parents in their professional choices.

It should be reminded that the above data only shows the tracking evaluation of the training quality of the 2020 graduates, and the future development is still unknown. Candidates are advised to consider multiple factors such as employment prospects, social needs, and personal interest preferences when choosing a major, and must not blindly follow the trend.

Science and engineering: computer majors have high incomes; civil engineering majors can best “apply what they have learned”

According to the data from the Blue Book of Employment in 2021, among the top ten science and engineering majors with a large number of graduates in 2020, the computer major has the highest monthly income (6800 yuan) after graduation, and the computer and data processing, Internet development and application personnel are the majors graduated After the main work. Other higher-income professional categories include electronic information (6091 yuan) and automation (5917 yuan).

If high income is not the only career pursuit, mathematics and electrical majors may also be a good choice. More than three-quarters of graduates of these two types of professional employment have found a job that satisfies them, with employment satisfaction of 76% and 75% respectively.

From the perspective of the relevance of work and majors, 87% of civil engineering majors in the 2020 class are engaged in jobs related to their majors, and electrical majors are also highly related to majors (81%). Therefore, it is recommended that students who choose to study in these two majors, pay special attention to the cultivation of professional knowledge and skills during the university, which will be more conducive to entering a better career development platform after graduation in the future.

Humanities and social sciences: Management science and engineering majors have an advantage in income, and 90% of education majors realize the “gardener dream”

Among the ten humanities and social sciences majors with a large number of graduates in 2020, the highest average monthly income is management science and engineering (5701 yuan), and its representative majors include information management and information systems, engineering management, etc.; Later, he majored in finance (5587 yuan).

In contrast, although the income of education majors is not high, the employed groups have a higher sense of professional happiness, and 90% of them are engaged in professional-related jobs after graduation, such as elementary and middle school education personnel, early childhood and preschool education personnel, education and training Personnel is the main occupational category engaged in. The vast majority of students with “gardener dreams” can achieve their ideals better after studying in this type of major.

At the same time, it should also be noted that the 2020 economics and trade majors have a 51% correlation with majors, and about half of the graduates are engaged in jobs outside of their professional fields. Therefore, it is recommended that students who choose this type of major pay more attention to the cultivation of general work abilities during their university studies, such as communication skills, cooperation skills and other workplace “soft skills”, which will help them develop better in a broader employment field.

Medical: Generally speaking, the initial income after graduation from undergraduate is not high, so be prepared for further studies

In recent years, with people’s emphasis on health, coupled with the sudden impact of the epidemic in 2020, medical majors have become popular for admission. Stable industry, high social status, and good income seem to be the general understanding of the future jobs of medical graduates. In fact, what is the quality of their employment?

As can be seen from the table below, among the five medical professional employment groups with a large number of graduates in the 2020 undergraduates, about 90% have engaged in professional-related jobs after graduation. Among them, the clinical medicine professional work and professional correlation reached 96%. The job satisfaction of medical technology, nursing, and pharmacy majors is relatively good.

Due to the characteristics of the medical industry, the salaries of medical graduates in the early stages of work are generally not high. Moreover, many large medical institutions now require a master’s degree or above for recruitment. Therefore, choosing to embark on the path of medicine requires preparation for continuous study in the professional field.

the data shows: The follow-up evaluation of the training quality of the 2020 undergraduates half a year after graduation will be completed in early March 2021. The national sample of undergraduates is 124,000. Covering 401 undergraduate majors, covering 30 provinces, autonomous regions and municipalities across the country, covering 582 occupations and 330 industries engaged in by undergraduate graduates.

One is “Three Body” , One is “Lost Southern Border” .

They won the highest awards in science fiction, the Hugo Award and the Nebula Award (the same year, “Three-Body” was also shortlisted for the Nebula Award, but unfortunately they lost.

The film and television adaptation of “Three-Body”, after many twists and turns, was finally difficult to give birth, but this novel was released as scheduled, it is-“ Annihilation “.

“Annihilation” is adapted from the first “Annihilation” in the “Forsaken Southern Territory” trilogy by Jeff Van der Meer.

The film tells the story of an alien meteorite hitting the lighthouse on the earth, forming a magical area around the lighthouse—— flash , The biological DNA in the flash will produce mutations.

In order to investigate the truth about her husband Kane’s amnesia, the biologist Lina (Natalie Portman), a biologist who does not know the truth, volunteered to join the next batch of dispatched action teams. Physicists, geomorphologists and medical staff, the five women embarked on a journey of “destruction” together.

Interestingly, the producer reminded the audience before the show: “Students and pre-school children should be accompanied by their parents to watch.”

However, when the film was released in China, it only cut more than 1 minute.

However, this short period of more than one minute contains three fragments.

At the beginning of the film, because the scope of the flash was expanding, the government sent professional scientists and troops to investigate the flash.

However, the people who entered were without exception, all had gone, except for the husband of the heroine Lina, who suddenly returned home but was dying.

In desperation, in order to save her husband, Lina, a biologist, decided to enter the “Flash” with four other female scientists in various fields.

As soon as they entered the flash, they lost their previous memories, and the remaining food showed that they had entered the flash for at least three days.

Not only that, but also something that has never been seen before.

For example, it is obviously the body of a crocodile, but it has shark teeth; a vine, but there are several different kinds of flowers growing.

And the closer they get to the lighthouse, the more mutated species they find.

Even nuclear radiation cannot cause such a strong and rapid mutation. As a biologist, Lina is puzzled.

As they continued to move forward, they soon found the previous military base, which was also the place where Lina’s husband served.

Lina accidentally found an undamaged DV, and found a shocking scene in it.

Immediately afterwards, they discovered the comrade in front of her husband, who was hung on the wall after his death and became a mural.

The teammates who saw this scene were all frightened, and they wanted to leave the flash in horror, but all the physical equipment was out of control, and they couldn’t find the way back. They had to stay at the military base temporarily.

That night, Cass was abducted by a dark shadow, life and death are unknown; Anya was on the verge of collapse, tied the other three people and asked them to tell her the truth, because she thought it was the three of them who killed Cass;

At this moment, they heard Cass’ call for help. Anya went out to find out and found that the sound was actually coming from the mouth of a skeleton black bear…

The truth gradually became clear. In the flash, all human genes would mutate rapidly, and it would reflect the genetic fusion of other organisms, and eventually humanity would be annihilated.

Seeing the sacrifices of her teammates one by one, Lina decided to destroy the meteorite before she was conscious.

She came to the lighthouse step by step and found another DV, which recorded the desperate self-immolation of her husband.

It turned out that the husband who returned to his side was just a clone in the flash.

And after she entered the lighthouse, a clone like her began to imitate her behavior…

At the end of the film, Lina returns to the real world, but who is her true identity?

Is it the real Lina who escaped, or is it a clone?

Since the film was released, this issue has been controversial.

Some people think that the real Lina has been burned to death, and it was the clone who escaped. She and the clone’s husband happened to implement the plan of colonizing the earth.

It was also said that it was Lina who escaped, but her genes have been rewritten in the flash. She is no longer Lina in the true sense, and the special symbols in her hand are all hints.

In this regard, Brother Qi did not want to explain and prove too much, after all, this is the suspense left by the director.

While in the film Three cuts , Respectively:

1. The hostess Lena and the team came to the abandoned canteen and found an undamaged DV, which recorded the video of her husband before his death.

   Because the plot was too bloody, it was cut before it was released.

   

2. The heroine’s comrade-in-arms, geomorphologist Cass, was attacked by a skeletal black bear. When everyone found her, they found that she was dead.

   The process of discovering her was deleted in the middle, leaving only the hostess to see Cass lying on the grass.

   As a result, there was a gap in the connection between the front and back stories, and it was difficult for the audience to understand the plot without watching it several times.

   

3. An Ya, a medical worker, was torn beyond recognition when he was attacked by a skeleton black bear.

   When it was released in China, only part of the footage of Anya being attacked by Anya was left. As a result, many viewers mistakenly believed that Anya’s entire head was bitten off by a skeleton black bear.

   However, the impact here on the understanding of the plot is not big, it is just too bloody.

   

   However, in terms of domestic popularity, “Annihilation” and “Three Body” are completely different from each other.

   However, it was the first to be adapted into a movie, with a unique aesthetic style that perfectly blends horror and science fiction.

   In addition to the profound and long theme and pattern, it has won the recognition of many audiences.

   

   As a representative of hard science fiction movies, director Alex Garland still does not forget to build a solid scientific foundation for the movie when dealing with such an overhead science fiction story.

   To this end, he invited Adam Rutherford, a geneticist who had collaborated in “Machines”.

   Under his guidance, the core of the film’s narrative logic is realistic, rational and empirical.

   

   At the beginning of the film, Natalie Portman’s meaningful “cell” lesson by the biology professor is actually a foreshadowing intentionally planted by the director.

   She first introduced another possibility of “origin of species” to the audience, that is, all cells are divided from one cell, one becomes two, and two becomes four.

   Then, she introduced a key scientific concept that exists in reality—— HeLa cell .

   

   In 1951, a surgeon at Johns Hopkins University Hospital (the school where the female lead worked) took a tissue sample from her tumor and cultured it in the laboratory.

   Scientists are surprised to find that unlike ordinary human cells that die by themselves after a certain period of time, HeLa cells not only do not age, they can divide indefinitely, and they proliferate abnormally and are extremely infectious.

   Through this arrangement, the director provided a certain scientific basis for the series of bizarre biological phenomena that the follow-up heroine discovered after entering “Flash”.

   

   Gene refraction , Is another important concept in the film.

   As the heroine’s team went deeper into “Flash”, their understanding of the place they were in gradually became clear.

   This scientific concept is explained orally by physicist Josie.

   It turned out that “little light” is a prism rather than a barrier. Like light, it refracts the DNA of all living creatures in it, and gradually forms the sight before us.

   

   Of course, these concepts are just the tip of the iceberg of the whole movie.

   The brilliance of “Annihilation” lies in its hidden mystery in every detail.

   In my opinion, “flash” is undoubtedly a more advanced life form, projected on the earth’s laboratory.

   

   In the early days, when humans did biological research, they would often choose to place a white mouse in a certain experiment, and by observing whether its behavior, genes, appearance, etc. changed, to draw conclusions about the impact on humans.

   The “flash” is similar to this phenomenon. In the film, the human being who enters is undoubtedly the “little mouse”.

   They don’t know anything about everything around them, until they undergo terrible mutations, they will gradually feel fear.

   

   Unfortunately, despite its good reputation, the box office of “Annihilation” is not satisfactory.

   In my opinion, the director’s methods are brilliant, but the film cannot achieve harmony in form and content.

   It seems that “Annihilation” is just a short story, abruptly pulled into a feature film.

   

   Therefore, it has always been very difficult to adapt science fiction into a movie.

   As China’s most well-known science fiction novel, the dystocia of “Three-Body” is actually traceable.

In 2016, at the Frontier Conference of the White House held at the University of Pittsburgh, the then-U.S. President Barack Obama had a fist with Nathan Copeland, a robot arm user, while visiting innovative projects. A mechanical arm that completes direct tactile feedback via a brain-computer interface can allow paralyzed patients to complete the action of pouring water from one cup into another more quickly and naturally. On May 21st, a research team from the University of Pittsburgh in the United States published a study “A brain-computer interface that evokes tactile sensations improves robotic arm control” in the top international academic journal “Science”. Research says that when a person controls an object with his mind, the robotic arm can provide direct tactile feedback to the person’s brain. In the past, robotic arms could only be guided by vision. The team has been working with Nathan Copland. Fifteen years ago, the teenage Copeland was paralyzed in an accident. He has now learned to control the movement of a robotic arm through a brain-computer interface. Copeland said, “When I only have visual feedback, I can only see that the hand touches the object. If I use it to pick up things, sometimes things will fall off.” Copeland needs to complete a typical grasping task. About 20 seconds. “With sensory feedback, he can do it in 10 seconds,” said Jennifer Collinger, an associate professor in the Department of Physical Medicine and Rehabilitation at the University of Pittsburgh. (Note that the colon is only used in very formal or important occasions) Collinger said that tactile information is very important for the use of prosthetic robotic arms, “because it is difficult for you to grasp an object that you can’t feel.” Even for simple things, such as picking up a cup and trying to move it. Maintain proper pressure during the process, which depends to a large extent on the tactile feedback of the hand. Therefore, Klinger and a team of researchers spent years looking for ways to add sensory feedback to robotic arms and hands. The research team used a two-way brain-computer interface to record neural activity in the motor cortex and generate tactile sensations through micro-stimulation of the somatosensory cortex in the cortex. In the experiment, the researcher first placed electrodes in the area of ​​the Copland brain that processes sensory information, so that electrical impulses can be used to simulate a series of sensations. Collinger said, “It turns out that the sensation produced by stimulating the fingertip-related areas of the brain is like coming from one’s own hands.” Next, the University of Pittsburgh team studied how to generate these signals when the robotic arm is in contact with an object. The last step is to time when Copland completes some tasks, such as picking up a stone or pouring water, how much time it takes if there is tactile feedback. The results show that Copland completes some manual tasks at roughly the same speed as humans use their own hands. Copeland revealed, “The intensity of this sensation actually varies according to the amount of force the hand exerts on the object. So I can also tell if I have grasped it. There is an additional benefit, after the increased tactile sensation , The feeling of using the robot arm is more natural. This kind of control is very intuitive, so that I basically just think about things, but it seems to be moving my own arm.” Jeremy D. Brown, assistant professor of John C. Malone in the Department of Mechanical Engineering at Johns Hopkins University, said that the significance of the research results goes far beyond the robotic arm. “High-tech prostheses also work better when simulating the sense of touch. Some are achieved through vibration or other forms of tactile feedback. This is the same way that many smart phones help users type on the screen.” The latest prostheses operate just like our natural limbs. Their elbows can be bent, their wrists can be rotated, and their fingers can be grasped. But most sensors still only have basic capabilities, such as detecting resistance or temperature. Before they have direct tactile feedback, they are actually very clumsy. And when using my hand to touch the surrounding objects, as Brown said: “I can feel pressure, feel sliding, feel whether the object is wet or dry. I can feel its texture, I know it is rough Still smooth.” Scientists are just beginning to learn how to make artificial hands and fingers that can detect these subtle features of objects. Brown said that as prosthetics or robotic arms provide more sensory feedback, they will become more useful. “The sense of touch is not just for flexibility. It’s not just the ability to reach into your pocket for the key. It can also hold your lover’s hand and feel the emotional connection.”

The work is in the Top 10 scientific books of the year by Booklist, Top 11 books of the Daily Beast and was voted by the New York Times Book Review as a Notable Book in 2012. (Source: Medisights) The faces of murderers are different With disease origin, David Quammen weaves an exceptional story, a detective novel with very different, but also very real, killers. They are viruses, bacteria and protozoa that cause disease in animals, but sometimes, they will change their target and jump to humans. Each chapter of the book is a journey in pursuit of a new criminal, led by a team of detectives from all over the world. The book is the notes of David Quammen in the process of accompanying them, following the traces to find the culprit. After the first chapter on the terrible virus that decimates both horses and humans, the Ebola virus emerges through a dark story, with dead gorillas stacked on top of each other, carrion in the woods and magic. The story doesn’t need the usual Ebola hype to create a macabre atmosphere (with bloody tears and melted organs) and the author doesn’t need to, because the disease itself terrible enough. He is more interested in delving into these diseases, learning what we already know about them and how that helps us prevent new diseases from appearing in the future, while limiting their consequences. their fruit. In each chapter, the diseases gradually become clear, starting with just a couple of rumors, a few mysterious deaths that seem unrelated to each other. The investigation process gradually unravels the problem, until finally the truth of the culprit is revealed. Along the way, we’ll see the myriad ways pathogens can move from host to host – through feces, secretions, mucus and blood – and explore possible dangerous behaviors leads to exposure: climbing trees, drinking date sap, eating or simply touching dead animals. The author also looks for unintentional accomplices who are animals that carry the disease before it is transmitted to humans: pigs, birds, monkeys, gorillas and bats. The Detective’s Journey However, the real heroes here are the detectives – scientists who work non-stop, from the lab to the field, looking for answers to cases committed by petty murderers. baby caused. Not only talented in describing how the virus works, David Quammen is also very successful in painting portraits of those heroes: from molecular biologists studying SARS “with the instincts of a epidemiologist with the courage of a red-faced monkey”, to the ecologist with a passion for exotic oriental dishes, to the veterinary pathologist with “the tough and stern body of a The former rugby player has passed the age of 40. The historical details can be found in the book as well: 19th century scientists used optical microscopes to look for tiny organisms in the blood cells of malaria patients, while the virus continued to hide behind a veil of mystery until the invention of the electron microscope in the 1930s. Readers also see important historical milestones such as: President Hoover banned the import of parrots into the United States; an outbreak of arthritis and a rash, preceded by contact with deer ticks, in the town of Lyme in Connecticut; and a series of seemingly harmless, but actually deadly, cases in a series of male patients in the United States in the 1980s. Author David Quammen. (Source: Town Hall Seattle) David Quammen has carried us around the world, from the labs to the field with investigators – bat traps in China, monkeys in Bangladesh, deep into the jungles of Cameroon. Towards the end of the book, we’ll leave reality a little behind and embark on a fictional voyage to the origins of HIV along the Congo River. The author also asserts that the appearance of diseases transmitted from animals, pathogens that find us from other organisms, is not new, but is on the rise. He seeks to find the reason behind that phenomenon in the final chapter of the book: the huge population of humans, along with the immense amount of livestock, the destruction of natural habitats, damaged ecosystems. disruption – things that can completely turn into a debate about nature’s revenge on humanity. David Quammen is one of today’s most influential journalists and authors, a three-time US National Magazine Award recipient. His articles have been published in famous magazines such as National Geographic, New York Times, Rolling Stone and Harpers.

Over the past decade, research has shown that enjoying music from vinyl really creates an enjoyable listening experience. In fact, audiophiles prefer to listen to music from vinyl sources, it gives the feeling that we are in the middle of a performance, a very magical experience! Turntable also offers a special physical interaction, you can hold the cover, share with friends albums with impressive cover designs. It can be said that it is a very special connection between the listener, the album cover, the artist, the turntable and the music stage. No.5105 brought the disc back to the world of Mark Levinson in a very special way. The look, feel, feel and design are so beautiful that it can’t be an exaggeration to use the word “perfect” by Mark Levinson No.5105 and it also perfectly blends in with the design of the other brands. equipment of the 5000 series. Like the rest of the 5000 Series, Mark Levinson’s engineers used 1in thick aluminum plate, the screen hidden deep behind the glass with familiar metal buttons to create a uniform design language. The aluminum chassis is solidly machined, finished with a black powder coating that feels really luxurious and classy. No.5105 charcoal tray has a rectangular aluminum design with sharp cutting lines. The plinth base is CNC made from a very large rectangular aluminum monolith, then hollowed out the gut so that components can be attached directly from below. At first glance, users may think that the device is assembled from individual components, but this is a complete monolithic product with a lot of intricately combined details. The lever of the No.5105 charcoal wheel has a double-axis rotation, which allows the lever to move up and down, left and right easily, and more importantly, this mechanism allows the tonearm to perform twisting movements. complex. This is an important factor, because the cartridge needle must always “companion” on the LP track. In particular, the sleeve of No.5105 is made from carbon fiber because this is a very hard and also very light material. When Mark Levinson engineers selected the tip to go with this charcoal, they had to try many tests and listen to the sound to make sure the selected cartridge had to deliver a sound quality that was in tune with the performance philosophy, sound color and tone. , the way to represent the image, the ability to create sophisticated dynamics similar to No.5105. Because the charcoal tray is a purely mechanical device, the needle head must also work extremely well with the lever and the rest of the charcoal plate. And Mark Levinson’s final decision was the Ortofon MC Quintet Black S cartridge. Mr. Chris Robinson – Global Coaching Director of Mark Levinson Mr. Chris Robinson – Mark Levinson’s global training director said: “I feel very happy that I still keep most of my favorite vinyl records over the years. For example, discs made with technology. in UHQR (pressing each disc by hand from vinyl), especially the album of the group SARGENT PEPPER.And when I listen to that album again on No.5105, the detail and realism gives me an extreme musical experience. It’s an incredibly emotional experience!”. The turntable is loved by listeners for its simplicity, from sound quality to spiritual value, and at the same time, it also brings a sense of nostalgia. And with Mark Levinson’s No.5105 turntable, users will experience a combination of modern functionality and classic beauty, where science meets analog art.

Wuhan Institute of Virology, China. Photo: AFP 59 leading biological laboratories in the world The Wuhan Institute of Virology is among the most secure, often referred to as biosafety level 4, or BSL4. Such laboratory facilities are built to operate safely and securely against some of the world’s deadliest viruses and bacteria, which can cause serious diseases for which there is no cure or vaccine. . “There are air-conditioning filtration systems that prevent viruses from escaping through exhaust gases and wastewater, which are treated with chemicals or high temperatures to make sure nothing remains. at,” Gregory Koblentz, director of the Biosafety Program at George Mason University, told AFP. In addition, the researchers themselves are professionally trained and wear protective gear when conducting experiments. There are about 59 such biological laboratories around the world, a report co-led by Mr. Koblentz published this week said. “There are no mandatory international standards for safety, security and accountability standards for diseases,” the report said. Accidents can happen at any time Accidents can sometimes happen in even the world’s top facilities and are even more likely to happen in thousands of lower-end labs. The H1N1 virus – the same type of virus that caused the 1918 pandemic was leaked in 1977 in the Soviet Union and China, and then spread around the world. In 2001, a mentally challenged employee at an American laboratory sent parcels of anthrax spores across the United States, killing five people. Two Chinese researchers were exposed to the SARS virus in 2004 and spread the disease to others, killing one person. Lynn Klotz, a senior scientist at the Centers for Arms Control and Disarmament, has raised the alarm about the threat to the public from such experimental facilities. “Human errors account for more than 70% of errors in laboratories,” the researcher said. Controversy entitled “Strengthening the research function” There are controversies within the US government, which also funds the Wuhan coronavirus research program, and some independent scientists over whether gains of function – GOF) should be conducted. GOF studies focus on tailoring pathogens to make them more infectious, more dangerous, or easier to escape from treatments and vaccines – all with the aim of learning how to cope with them more effectively. This field has been going on for a long time. The debate heated up when, in 2011, two research groups showed that they could make avian influenza viruses more infectious in animals. Harvard epidemiologist Marc Lipsitch told AFP he was concerned that “would create a strain of the virus that, if it infects laboratory workers, not only kills the person but causes a pandemic”. “This study was not requested and does not contribute to the development of drugs or vaccines,” said molecular biologist Richard Ebright of Rutgers University, one of the strongest opponents of the type of research. this said. In 2014, the US government announced it would stop funding such research, but the process was criticized for its lack of transparency and trust. Late last year, a non-profit organization received funding from the US for research “to predict the risk of virus escaping from the laboratory” from corona virus in bats to humans in Wuhan. This week, before a question from Congress, experts Francis Collins and Anthony Fauci of the US National Institutes of Health also denied conducting activities to strengthen research functions.

Flight equipment application PTC2 uses drones to manage and operate the transmission grid. Assigned by the National Power Transmission Corporation (EVNNPT) to pilot deploy many scientific and technological applications in the management and operation of the transmission grid, since 2017, PTC2 has researched and applied drones in the field of power transmission. management and operation of the transmission grid. The application helps to reduce the level of burden, improve safety and efficiency, and productivity for workers. Mr. Tran Thanh Phong, Director of PTC2 said that in 2019, after being accepted by EVNNPT, PTC2 has synchronously deployed to all affiliated units to deploy the application of flying equipment in the inspection of the power grid and supporting construction supervision and acceptance of power transmission works. From March 2020 up to now, PTC2 has deployed the application of aircraft to periodically check 1,100 km of 220 kV and 500 kV lines with a total flight time of 29,000 minutes. Thereby, it has contributed to reducing the burden, improving safety, efficiency and productivity for workers such as climbing high, contacting electrical equipment with large electromagnetic fields, moving on difficult terrains. difficult access to dangerous plants and animals. Rapid inspection deployment, being able to access locations in areas divided by rainstorms, landslides, real-time recording of the current situation with good quality images, clear viewing angles to help analyze information more accurate assessment and, most importantly, does not require power line interruption. Mr. Tran Thanh Phong analyzed, when applying flying equipment, according to preliminary calculations, on average, to test 1 km of 500 kV transmission line, it takes 0.52 time to perform the traditional method, and 0. 25 workers, down 0.27 jobs (52.38%). In addition, it also saves a lot of time, costs, and other human resources such as: checking thematically on corridors, conductors, lightning conductors, techniques, insulation status, accessories… Along with that, the application of flying equipment to support construction supervision of power transmission works, inspection, supervision and acceptance of pole erection, inspection of conductors, accessories, route corridors, etc. 220 kV, 500 kV works. Not only that, the application of flying equipment helps closely monitor the technical status of the power grid from above and in places where the human eye cannot see (or is very difficult to see). From there, it contributes to reducing the level of burden, improving safety, efficiency and productivity for workers such as climbing high, contacting electrical equipment with large electromagnetic fields, moving on difficult terrains. , access to dangerous plants and animals. Check for dangerous landslide areas or break off during flooding. Efficiency from surveillance camera system thống Camera system to monitor power transmission lines. An effective application for EVNNPT and PTC2 is the installation of line surveillance camera systems. Realizing the high efficiency and applicability of line cameras, PTC2 has installed cameras at all affiliated Power Transmissions since 2020. Up to now, on the PTC2 grid, 31 CCTV cameras have been installed on the transmission lines of the company. The cameras are connected to the company’s dispatching room so that functional departments as well as company leaders can monitor the current status and direct handling remotely when there are abnormalities on the line. According to Mr. Phong, the camera has a wide field of view, so it helps remote observers to easily detect and accurately assess abnormalities arising on the route such as: fires near the corridor, landslides, vehicles passing photos affect the safe operation of the line. Along with that, the camera helps to quickly access the scene to locations in flooded areas, thereby capturing the situation of the route section and directing appropriate handling. Since installing the camera up to now, PTC2 has detected 35 unusual incidents that may affect the safe operation of the line, thereby taking appropriate measures to ensure operation. In the coming time, PTC2 will continue to research on technology solutions for cameras, solutions for data transmission and analysis, image processing, and propose equipment and installation at necessary and important locations for roads. cord.

Mastering technology, constantly creating… is the “heart command” of Vietnamese oil and gas people. Mission across 60 years Referring to research, development and application of science and technology (Science and Technology) at PVN is a cross-cutting task in the process of formation and development of the Group. Resolution 41-NQ/TW of the Politburo on orientation “Strategy for development of Vietnam’s petroleum industry to 2025, vision to 2035”, as well as Resolution 55-NQ/TW on orientation “Strategy Vietnam’s national energy development to 2030 with a vision to 2045” emphasized: PVN must strengthen the application of scientific and technological advances in the search and increase of oil reserves, production and business. oil and gas, electricity, nitrogen, new energy (shale oil, gas hydrate, hydrogen gas…) to ensure national energy security. General objective PVN’s development strategy especially emphasizes the need to build strong scientific and technological potential with breakthrough solutions. This is considered the driving force and foundation for PVN to accelerate development and develop sustainably. Through 60 years of construction and growth, PVN has constantly improved its research and application potentials of science and technology, actively absorbed advanced techniques and technologies, and promoted creativity and efficiency of existing technologies to achieve level with oil and gas companies in the region and in the world. Hundreds of awards have been awarded for achievements in science and technology of the oil and gas industry, including noble awards such as 5 Ho Chi Minh Prizes & State Prizes in Science and Technology, many VIFOTECH awards… And during the year Currently, continuing to 6 most typical works and projects, the Ministry of Industry and Trade has also been nominated for the Ho Chi Minh Prize & the State Prize in Science and Technology. The Petroleum people who make applied scientific works have worked hard for many years, doing both expertise and research and experimentation. For example, the Cluster of Science and Technology Works “Research and develop technology for design, construction and installation of super-long and super-heavy marine oil and gas projects suitable to Vietnam’s conditions” was deployed and completed after more than 10 years. Research and application of technological solutions in collecting, processing and using associated gas in fields of Vietsovpetro LD Vietsovpetro and neighboring fields has been carried out and deployed continuously for 25 years.. .; the TBM-02 portable synthetic carota metering station system has been researched and manufactured for 21 years; the solutions to apply science and technology to optimize the production process of Dung Quat oil refinery plant are researched and completed. completed in 12 years;… Success of “poor children” The number of benefits and achievements of the above-mentioned scientific works for the Oil and Gas industry as well as for the country, it is easy to ignore the difficult starting factor… But in fact, few people know that starting At the beginning of these scientific works, the Oil and Gas people all embarked on the implementation with the mentality of “the poor children”. The success of PVN’s science and technology cannot be ignored without mentioning the cluster of works “Research and application of technological solutions in the collection, treatment and use of associated gas in fields of Vietsovpetro LD Vietsovpetro and neighboring fields”. . At that time, LD Vietsovpetro could only exploit oil at Bach Ho, but the technology at that time only exploited oil, and the associated gas had to be burned. Meanwhile, the country is seriously lacking electricity for economic development. That fact has prompted Vietsovpetro’s officers and engineers to research and carry out gas collection, transportation, processing and bringing the associated gas to shore for power generation and nitrogen fertilizer production. After oil exploitation, with breakthrough scientific and technological solutions, in the condition of lack of facilities, Vietsovpetro pioneered to bring companion gas from Bach Ho field to shore, creating a leap in the oil and gas industry. Vietnam, creating a foundation for the development of modern gas industry. The story of researching and manufacturing the TBM-02 portable synthetic carota metering station system is also a scientific and technological mark of PVN. In order not to be eliminated from the game of oil and gas services, the staffs of Vietsovpetro Wells Geophysics Enterprise have tried their best to learn and create new things, which are more technologically superior. In those years, Vietsovpetro experts and engineers have picked up equipment of the type “cannot be repaired, cannot be bought” to dissect, research, and then integrate their most preeminent features and manufacturing a general carota metering station costs only $5,000, less than 10% of the equipment price if it has to be imported from abroad. Especially impressed with the word “portable” in the research work made by the equipment of a Russian measuring station in the past, together with the corresponding combined equipment with a mass and weight of up to hundreds of kilograms. Now, Vietsovpetro’s engineers have created a general measuring station that can interpret geophysical data, measure oil-filled fractured rock foundations…weighing less than 10kg, compact as a personal computer multiply. The East Sea Oil and Gas Operating Company (BIENDONG POC) was assigned to research and implement the construction and manufacturing of large works of the East Sea 1 project. In which, the superstructure weighs 12,500 tons and the foot block. The 11,500-ton base of the Hai Thach housing and central technology platform (PQP-HT) are works with a volume exceeding many times that of previous constructions. This is a task that international monitoring and consulting experts consider impossible. However, PTSC Marine Mechanical Services Company (PTSC & MC) – the unit assigned the responsibility, overcame difficulties to complete the project after 2 years. Up to now, with the research, completion and application of the Science and Technology Complex, successful implementation of design, construction, manufacture and installation of super-heavy-heavy drilling rigs, PTSC&MC has become the only international EPCI contractor. of Vietnam to the world market. When Dung Quat Oil Refinery Plant was in operation, the team of engineers and staff of the factory were all apprentices, so they stumbled and problems were inevitable. Therefore, the initial product quality of NM was in a state of “fluttering”. At that time, PVN has determined that to improve the quality of NM operation is a long process. Accordingly, improvement and creativity right in the actual production and operation of the factory has become a regular and continuous action. Although the production and business results of Dung Quat Oil Refinery were not high in the first years, PVN still believes that the young staff and engineers will make efforts to improve the quality of plant operation. Over the past 12 years, more than 30 solutions and initiatives have been completed, increasing the factory capacity beyond design, ensuring product quality to the highest level. Currently, science and technology has been applied in all fields of production and business activities of the Group, especially research focusing on professional and specialized directions. The basic investigation of oil and gas has been actively deployed by PVN and the research results are considered as a reliable scientific basis, having important implications in formulating the development strategy of PVN. helping to make the right decisions and policies in production and business activities. The research, development, proposal and successful application of petroleum science and technology solutions not only bring great economic benefits to the country, but also make important contributions to the science and technology industry. oil and gas of Vietnam and the world. Those are eloquent demonstrations of the creative ability of oil and gas people – who always deserve to be entrusted with the belief to make the impossible possible.

The authors of Ho Chi Minh City University of Technology have applied blockchain technology to build a system for issuing and managing diplomas and certificates. To issue a certificate, the training institution registers an account and logs in to the system to create embryos. After filling in the student’s information, the course, etc., the training institution can print it to issue a certificate or issue a digital certificate. Each certificate is issued with a QR code, which can be looked up and verified on the student’s information and the certificate on the mobile application. The system helps to reduce time and costs for training institutions and quickly detect cases of tampering. The glue that helps regenerate nerve cells Researchers at the University of Georgia (USA) have studied a special glue in the form of hydrogel to aid in the recovery of brain cells. The researchers implanted the hydrogel into mice with traumatic brain injury. After 20 weeks, the mouse’s cell repair process was enhanced, motor function improved. The results showed that this glue not only protects tissues from damage, but also regenerates functional neurons at the affected site. The results of the study hold promise for the medical profession to prevent cognitive decline or tissue loss in patients with traumatic brain injury. New battery development Russian scientists have developed a new type of battery that can be charged about 10 times faster than commonly used lithium-ion batteries. Tests show that the new battery can work well in emergency charging situations and in low-temperature environments. The new battery is also safer for the environment.

The COVID-19 pandemic first broke out in Wuhan city, Hubei province, China. Photo: Getty Images The United States and several countries are closer than ever to defeating COVID-19 thanks to progress in vaccination against the SARS-CoV-2 virus. But the world still does not know how this deadly virus appeared, and there is a growing opinion from the scientific community that it does not happen naturally. The US is stepping up calls for more research and warning about the risks of future pandemics. Washington is also more open to weighing the theory that a mistake or failure in a Chinese laboratory caused the COVID-19 pandemic. Meanwhile, the Chinese Government completely rejected this hypothesis and said that the dossier to trace the origin of the COVID-19 epidemic was closed. What’s new? According to CNN, a recent US intelligence report found that several researchers at the Wuhan Institute of Virology fell ill in November 2019 and were hospitalized – a new detail on the severity of the symptoms. disease in these scientists. It is not clear whether the researchers at that time had COVID-19 but the Wuhan Institute of Virology (WIV) vehemently rejected the report, considering it a lie to promote the hypothesis that the virus leaked from the laboratory. . Scientists who worked for the WIV previously said the institute had nothing to do with COVID-19 disease until December 30, 2021. On May 24, China’s Ministry of Foreign Affairs also denied the information that three Wuhan researchers were hospitalized before the outbreak of COVID-19 and affirmed that this information was “completely untrue”. Spokesperson Zhao Lijian confirmed that the Wuhan Institute of Virology was not exposed to the SARS-CoV-2 virus before December 30, 2019, and its staff so far have not been infected. Scientists at the Wuhan Institute of Virology. Photo: AFP Meanwhile, on May 25, speaking at the US Congress, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said that the failure to fund previous research on Corona virus in bats in China. Quoc is a “negligence of duty”. According to Fauci, the US should have pursued to the place where the contact between animals and humans could lead to the spread of the virus between species. Dr. Fauci himself, the leading infectious disease expert in the US, said this week he did not believe the COVID-19 outbreak occurred spontaneously and prompted further investigation. A World Health Organization (WHO) adviser, Jamie Metzl, also said the leak hypothesis is possible, while scientists are “groping, creating and studying” the virus with the aim of vaccine development. “So I believe what could have happened was a leak, followed by a cover-up,” said Metzl, who served at the US State Department and the Atlantic Council during the US presidency. President Bill Clinton said. The conclusion is that further investigation is needed An in-depth study conducted by WHO in collaboration with the Government of China, published in March, explored the different possible origins of the COVID-19 epidemic and came to the conclusion that: although still It is not yet known how the disease originated, but it is likely that it spread to humans, either directly from bats, or more likely from an intermediate species that caught the virus from bats and then spread to humans. for human. Bats can be an intermediary that spreads the SARS-CoV-2 virus to humans. Photo: NPR The WHO report called the laboratory leak theory “extremely unlikely”, citing the fact that no laboratory staff in Wuhan were infected before December 2020 as an argument against this hypothesis. After the WHO report was published, its officials still called for an additional and public investigation from the Chinese side. Meanwhile, a newly released US intelligence report shows that laboratory workers of the Wuhan Institute of Virology have been sick since before December. According to WHO adviser Jamie Metzl, in the early stages of the outbreak of the disease. when China did not warn the world appropriately, Chinese officials blamed the transmission on an initial hotspot, a seafood market in Wuhan, which at this point was essentially Is not right. This expert said that there is a lot of evidence that the Chinese government initially tried to cover up the existence of the SARS-CoV-2 virus. “Whatever the origin of the pandemic, the first month, when China was spending all its energy trying to cover things up rather than fixing the problem, allowed the fire in the furnace to cause a fire in the kitchen.” into a house fire and a worldwide fire,” said Metzl. The Wuhan Institute of Virology became the center of doubts about the origin of the SARS-CoV-2 virus. Photo: Getty Images A group of well-known and experienced scientists also criticized the WHO report for not taking seriously the hypothesis that the virus leaked from the laboratory. According to them, this hypothesis was refuted within just a few pages of a hundred-page report published by WHO. The scientists wrote in the journal Science: “We must seriously consider the contagion hypotheses in the wild and in the laboratory until we have enough data.” Fear of a recurrence of a pandemic These “closed doors” have also helped conspiracy theories expand. Arkansas Republican Senator Tom Cotton has promoted the idea that the SARS-CoV-2 virus was purposefully created as a biological weapon. But there’s no concrete evidence to back up that claim, and experts still say it’s unlikely. Dr. Paul Offit, an infectious disease specialist at the University of Pennsylvania’s Perelman School of Medicine, told CNN it’s unlikely the Wuhan lab manipulated the virus to make it more contagious. but “we have to find out” the truth. Dr. Offit said that the world needs to do something to prevent another pandemic. “What I know is that they [Trung Quốc] must allow this [điều tra mở về nguồn gốc dịch]“This is now the third pandemic to emerge in the past 20 years,” said Mr. Offit. First there was SARS 1, then there was MERS. I think we can assume we’re not done with this yet.”

Irish people often tell each other stories about giants who were able to create an island just by taking a handful of sand and throwing it out into the sea. Professor Márta Korbonits said that such old stories have some historical basis. And hard to believe, scientists have found what they’ve been looking for all along. As it turns out, there are many Irish people with the AIP gene mutation. These mutations are responsible for the excessive height in some people. In the UK, these mutations are very rare (probability about 1 in 2000 people), and in Mid Ulster – Northern Ireland, these mutations are becoming more common (1 in 150). One of the most famous giants in Ireland was Charles Byrne (1761-1783) when he was 2.2m tall. According to legend, giants are extremely powerful, but in reality, they are not. They often suffer from heart problems, eye problems, and joint pain. Without proper treatment, most of these giants die before the age of 30. 2. Werewolves There are very few origins of werewolf legends because their lives are always associated with the forest. However, people have found archaeological ruins and cave paintings of the combination of people and things from ancient times. At that time, people always wanted to become stronger. So, they chose for themselves a summoned beast and took this form. To go to the battlefield, the warriors choose a powerful summoned beast that is the wolf. Before fighting, they will drink magic potion that affects the nervous system making them think they are invincible wolves. In addition, belief in the existence of werewolves is supported by the genetic condition hypertonia. It is an abnormal amount of hair growth on the body and face, also known as werewolf syndrome. It was not until 1963 that Dr. Lee Illis gave the name of this disease. Another psychological disorder is called Lycanthropy. This is a delusion that makes the patient think that he can transform into a species between man and animal. It is also believed that this disorder becomes stronger during the different lunar phases. 3. Vampires Porphyria is a rare genetic disorder (1 in 200,000 people). If either parent has the condition, their child has a 25% chance of having it. This disease causes a pigment imbalance, and hemoglobin begins to decay by ultraviolet light. People with this disease are greatly affected by sunlight. So the only time they can go out is at night. In more severe cases, the patient’s tendon is deformed, causing the fingers to constrict. The skin around the lips and gums becomes dry, the front teeth protrude and turn red. So they will look like vampires. In the Middle Ages, people with porphyria were burned by the judgment of the Inquisition. 4. Dragons Theory of a connection between dinosaur bones and dragons began in Mongolia. Here, the word “dragon” is found associated with different geographical names. This is because, in some areas of the Gobi desert, anyone can find dinosaur bones because they lie completely on the surface of the Earth. These skeletons are still abundant in this place causing many illegal excavations to take place. It is an important fact that there are no myths of this kind in Africa because there is no access to dinosaur remnants there. But why do we picture dragons like reptiles with claws and scales? This is explained by the way we see things around us. Their skeletons resembled the bones of modern lizards, snakes, and crocodiles. If you zoom in a few times these animals, they will look like dragons. Also added that lizards and snakes sometimes have two heads, like some dragons in fantasy or legend.

According to Mr. Hoang Trung, Director of the Plant Protection Department, the use of drones in pesticide spraying has many advantages compared to traditional methods. Currently, many countries such as China, Japan, Korea … have also applied this technology, especially the Food and Agriculture Organization of the United Nations (FAO) is also interested in and testing this technology in some countries. Africa to control the desert locust epidemic. In recent years, the use of flying equipment in pesticide spraying in our country has become more and more popular. However, there are still many issues that need to be studied when using this device. Photo: TL. With the initiative in the past time, businesses have gone through many channels, imported drones with diverse configurations and capacities … showing the ability to apply this new technology solution quite effectively in pest control. on plants. Later, the drone can also be applied to sowing seeds in the Mekong Delta provinces or to apply foliar fertilizers … In addition to the benefits such as user safety, large capacity, time-saving …, this device also has some issues to be clarified. Accordingly, it is necessary to have a scientific basis, to guide effectively and strictly according to the provisions of law. Currently, there are no official results to confirm that using drones in pesticide spraying helps reduce the amount of pesticides. In the FAO guidelines for use, the drone is still just a tool that must use pesticides in accordance with the dosage stated on the label. In addition, there is the current situation, many places have overstated information and advertising that any crop, any form of medicine can use drones. This is information that has absolutely no scientific basis. The Plant Protection Department recognizes the results from the initiative of enterprises and organizations in researching and applying scientific and technological achievements to production. However, to use it effectively, there is a scientific basis and in accordance with the law. Therefore, in the coming time, it is necessary to have more in-depth and comprehensive studies and evaluations on both the efficiency of use as well as the technical and economic efficiency of the drone. In particular, it is necessary to evaluate the safety level of using drones in pesticide spraying for other objects in the area of ​​use such as aquatic products, bees, etc. In addition, it is necessary to delve into techniques and find out the forms drugs, biological effects can be used appropriately and effectively with drones. Secondly, it is necessary to study plant objects suitable for the use of drones in pesticide spraying. For example, in areas where scattered trees and industrial crops are grown, the use of drones can be said to be ineffective, or as objects on the underside of leaves such as mosquito bugs, anthracnose, etc. Therefore, harmful organisms also need to be evaluated and classified to apply drones appropriately in spraying pesticides. For example, objects lying in the trunk, on the ground, weeds clinging to the base have almost no effect when using a drone. The Department of Plant Protection will also study to provide guidance on the form of drugs to be used with drones. From the perspective of a state management agency, the Department is responsible for clarifying this issue. The use of drones in the past time has been effective and has many advantages on rice, but there have been no scientific studies on other crops. Illustrative photos. Hoang Trung also said that the mechanism of action of the drugs also needs to be evaluated before being used with drones. In addition, it is necessary to evaluate the plant objects and harmful objects that can use drones in spraying effectively. On the other hand, it will be necessary to evaluate and classify according to the capacity and specifications of the drone corresponding to the appropriate crop objects. For example, a large-capacity drone can be suitable for spraying pesticides for rice or some crops, but cannot be used for vegetables because it will destroy the plants… From the above assessments, the goal of the Plant Protection Department is to work with businesses to come up with procedures and documentation for using drones across the country. In addition, the Department will also develop standards for testing pesticides used by drones. Many concerns about the limitations of drones At the meeting, some opinions suggested that there should be more specific and scientific studies in the application of drones in pesticide spraying. According to a representative of the Southern Pesticide Testing Center (Pesticide Department), in order to spray effectively, pesticides must be able to contact the objects that need to be protected or destroyed. However, the use of drones may have many limitations in pesticide spraying such as difficulty in contact with pests and diseases such as brown planthoppers, dry streaks below for rice or thick canopy trees… In addition, the use of drones will use less water than traditional also reduces the effectiveness of the drug. Another problem is that using a drone causes the particles to fall freely but slowly, so it is possible that some of the medicine will evaporate before reaching the leaves. Using a drone with a more concentrated drug concentration than traditional spraying can also cause acute poisoning of plants. In addition, the use of drones will cause waste of pesticides, affecting the ecological environment if used for scattered crops. The Center for Plant Protection in the South (Department of Plant Protection) said that the application of drones in the Mekong Delta is increasingly popular on rice and some fruit trees. Many farmers rate drones as highly effective against pests located at the top of the foliage. The use of drones in pesticide spraying still has many limitations that need to be studied. Photo: TL. However, with trees with uneven heights in the same area such as coconuts, the ability to contact leaves is not optimal because the drone can only fly at a certain stable height that cannot be continuously changed. The height is suitable for each height of the crop, leading to the not equally optimal distance of pesticides to the top of the tree. The Northern Center for Plant Protection also said that it is necessary to study and evaluate the effectiveness of drones and devise ways to use each drug. In addition, there is a need to have scientific assessments of the effects on the environment and plants when using drones to spray pesticides with high concentrations (due to less water). Because normally, the amount of water when spraying pesticides is 400-500 l/ha, while using a drone it is only about 15 l/ha. Mr. Nguyen Quy Duong, Deputy Director of the Plant Protection Department suggested that in the coming time, there should be more assessments on the process and effectiveness of using drones for intercropping areas. According to Mr. Duong, in the Mekong Delta, people now use pre-germination herbicides and except yellow apple snails at the same time, so there is a need for studies on the possibility of using mixed drugs when spraying with drones. In addition, it is necessary to have a baseline standard for testing devices and forms of medicine to come here, it is necessary to clearly state on the drug label the dose used (amount of water) when used with a drone. The Plant Protection Department said that based on the results of businesses and units that have applied drones over the past time, as well as international experience, the Plant Protection Department will develop a master plan to continue researching. Research and perfect both equipment and processes to use in a scientific, safe and most effective way for the application of drones in plant protection. In the immediate future, the Department of Plant Protection suggests that it is necessary to focus on researching and perfecting the drone application process for 5 groups of liquid drugs including EC, SC, SE, SL, ME; 4 groups of solid drugs including WP, SP, WG, GR. Regarding plants, focus on researching and perfecting the process of applying drones to rice (focusing on leaf rollers, brown planthoppers, rice blasts, powdery mildew, herbicides); fall and powdery mildew on corn; aphids, downy mildew on fruit trees (especially citrus, mango, litchi; industrial plants such as coffee, tea, and cashew; caterpillars on pine trees and silkworms on cruciferous vegetables).

GS. Trinh Xuan Thuan Born in 1948 in Hanoi, at the age of 6, he moved with his family to Saigon to live. As a child, he attended Jean-Jacques Rousseau High School (now Le Quy Don School, Saigon). GS. Trinh Xuan Thuan Graduating from high school in 1966, Prof. Trinh Xuan Thuan went to Switzerland to study engineering. He then decided to study astrophysics at the California Institute of Technology, then at Princeton University, New Jersey, USA. For the first time in his life, at the observatory on top of Mount Palomar, California, young Trinh Xuan Thuan observed the magic of the galaxy, moon and light from billions of stars through the telescope. The largest telescope in the world at that time with a diameter of 5.1 m. His life has been associated with cosmic astronomy since then. After completing his doctoral thesis at Princeton, GS. Trinh Xuan Thuan teaches at the University of Virginia since 1976, and has become a world-renowned expert on extragalactic astronomy. In which, the most prominent event is the GS. Trinh Xuan Thuan is the youngest known co-discoverer of the galaxy in the universe today, thanks to the study of observations made by the Hubble space telescope. That is galaxy I Zwicky 18. Called I Zwicky 18, this galaxy appeared just 500 million years ago. This discovery is shocking because the word I Zwicky 18 allows people to understand the first small galaxies in the early universe. Writing about the universe in a special way In addition to research, Prof. Trinh Xuan Thuan writes a book. From the research results, extremely attractive and interesting findings of astronomy, Prof. Trinh Xuan Thuan wishes to share with everyone about the beauty, harmony of the universe and the creation of nature. GS. Trinh Xuan Thuan is highly appreciated for his ability to popularize science. He began to write his first book ‘Mysterious Melodies – La Mélodie secrète, published in 1988′. Currently, there are about 20 books of GS. Trinh Xuan Thuan was translated and published in Vietnam as Origin, nostalgia for the early days; The Paths of Light, The Fullness of Nothingness, One Night… GS. Trinh Xuan Thuan writes three times more popular science books than specialized research books. He confided: “Because I want to meet more readers. If I write a book on a complex subject, only a few hundred people can understand it. I want the knowledge of science and astrophysics to spread in many readers. So I write books for the masses. If I’m lucky, my books will be read by hundreds or thousands of people.” When writing the book, Prof. Trinh Xuan Thuan wants to explain to the general public about the stars, the universe, about what astronomers have discovered; phenomena of the sun dying into a dwarf star, or stars ten times more massive than the sun, the sun becoming a black hole… In particular, when writing books, he did not use science but wrote about the universe in a literary way. GS. Trinh Xuan Thuan explains: The voice of the universe is math. Scientists all use math equations to understand the universe. But when I write the book, I do not use it, but use images in everyday life, to let the public understand the ideas that scientists find in the universe. Therefore, although writing about distant planets, cold galaxies, mysterious black holes… GS. Trinh Xuan Thuan always tries to use a simple but clear language. He refrains from using overly technical terms. For difficult concepts, he often refers to images in everyday life as an example. For example, in the latest book titled “One Night” (Pham Van Thieu, translated by Pham Viet Hung, Youth Publishing House, 2020), Prof. Trinh Xuan Thuan brings readers into a vast world, explores the night sky with easy-to-understand explanations. As a lover of poetry, he also quoted many verses and poems of famous poets. For example, when writing about the Moon, Professor Trinh Xuan Thuan quotes John Keats’ “Song of the Nightingale”: “The night is gentle/ And maybe Hang Nga is on the throne/ Among the stars of fairies/ But in Here, nowhere is it clear / Except for the breezes / On the dark and mossy leaves of the winding roads. He even quoted W. Shakespeare’s “Romeo and Juliette”: “Come, night, come here/ Romeo me, come back to me!/ I’m the sun in the dark/ Because I’ll lie under the night darkness of the night…”. In the spring of 2007, the famous work “Paths of Light” (Les Voies de la lumière) was awarded the Moron Prize by the French Academy. Two years later, Prof. Trinh Xuan Thuan also became the first Vietnamese in history to be awarded the prestigious Kalinga Prize by the United Nations Educational, Scientific and Cultural Organization (UNESCO). Soon after, the Institut de France awarded the Prix mondial Cino del Duca, recognizing the persuasive transmissions of complex knowledge of arid space science, yet blended under a contemplative, rich gaze. literature in his outstanding works. GS review. Trinh Xuan Thuan, Mr. François Delattre, French Ambassador to the US, respectfully called the Vietnamese-born astronomer a “world asset” when he devoted his life to the goal of “popularizing science”.

The 2021 Award evaluation process is carried out according to regulations, including checking application conditions; consult experts to review; evaluated at the Foundation’s Scientific Council (OSC) and the Award Council. On April 29, 2021, the Prize Council for 2021 met to evaluate and select applications. However, after more than 4 hours of discussion and voting, the Award Council decided not to recommend awarding the nominations. On May 13, 2021, the Minister of Science and Technology approved this proposal. Too few good records? Professor Ngo Viet Trung, Chairman of the Award Council, said that this year, although the number of applications for evaluation and selection was similar to previous years, after the initial review, there were only 2 scientific activities in Earth Science and Science. Environmental and Agricultural Biology nominate 2 entries for the Main Prize and 2 for the Junior Award for consideration at the Awards Panel. This year’s nominations are all in the experimental field, related to issues of concern to scientists around the world. It is the work of Assoc.Prof.Dr. Ngo Duc Thanh, Dr. Bui Minh Tuan on climate change in rain, and the work on the use of antibiotic substitutes in aquaculture by Dr. Do Huu Hoang, a project on the technical system of growing chrysanthemums on a large scale by Dr. Hoang Thanh Tung. Will young scientists have more opportunities at the Ta Quang Buu Prize? Prof. Nguyen Huu Duc, Chairman of the Physics Council, said that although this year the Science Council also received a number of applications, including works published in journals with IF coefficients, but did not nominate any works. to the Awards Committee. Explaining this, Prof. Duc said the reason is that most of these works have only been published about half a year ago, while the Physics Council thinks that it is necessary to evaluate the works at an international level, through by number of citations. “So the Physics committee members agreed to give it another year to have a more accurate assessment of the publication quality with these works.” In the Science Council in Mathematics, there are also two nominations that, according to Prof. Ngo Viet Trung, are of sufficient quality. However, at the time of voting, both of these applications did not receive 2/3 of the votes to be nominated to the Award Council. This may have caused a negative resonance if people did not understand the situation of this year “- Professor Trung shared. “However, I confirm that no works have been awarded the award that does not fully reflect the development reality of the country’s science and technology.” According to Professor Ngo Viet Trung, looking at the quality of international publication of basic science today, the number of articles in leading journals has increased markedly and the quality is much better than the time when there was a Ta Quang Buu Award. “However, each year the quantity and quality of applications for awarding the Prize depends on many other factors such as the self-nomination of scientists or the nomination of research and training organizations. create. Scientists are afraid to nominate themselves for the prize, while many agencies are not interested in nominating outstanding works. In addition, awarding a prize to an individual or to a work also limits nominations because scientific achievements are often confirmed through a cluster of works and through the cooperation of many scientists. Professor Ngo Viet Trung also said that it is important that the quality of the award is guaranteed. “It’s normal for an award not to be given by anyone. The Board of Directors has worked very seriously, not for the sake of having a prize but trying to award it, which will affect the prestige of the award. For example, China’s highest national award for science and technology (worth about $750,000) has gone without a prize twice, Mr. Trung cited. In particular, in 2015, there was no award, but China had a Nobel Prize in Medicine right before the national award. Young scientists need to be taken care of The 2021 season has passed, but according to Prof. Ngo Viet Trung, there are contents that the Foundation needs to discuss to draw lessons for the following years, so that the award can achieve the purpose of promoting research in basic science and technology. encourage young researchers. He also expressed the view that “need to pay more attention to young scientists”. “I and other members are trying to propose to the Ministry of Science and Technology so that each industry has a young award and the young award recipient will be a typical scientist for his or her specialty.” Prof. Nguyen Huu Duc also expressed his support that next year the regulations should change a bit, such as increasing the number of young prizes, and some more detailed award criteria. “Currently, the criteria of the award are heavy on hard indexes such as the influence of magazines, and the ability to deeply analyze the value of each work still has some shortcomings. Therefore, in my opinion, it is necessary to balance the hard criteria with the specific value and unique points of the work, plus expert opinion, public opinion because there are works published in ordinary journals but very difficult. excellent”. Ta Quang Buu Prize is an annual award of the Ministry of Science and Technology to encourage and honor scientists who play a key role in excellent scientific works, carried out in Vietnam, and published on the Internet. prestigious international scientific journals in the field of natural sciences and engineering. The award has been implemented since 2013, in the past 7 years, it has received more than 360 applications, awarded 16 main prizes and 4 awards for young scientists.

Only 19.1% of scientific journals are digitized This is the third time the Vcgate team has announced this result (the previous two times were in 2016 and 2018). However, this is the first time the team has evaluated the impact factor (IF) and H-index (cumulative influence) according to international practices. In 2020, there are 83 journals to be considered for inclusion in the Vcgate system and evaluated. Regarding the influence index calculated through the number of citations in 2020 of articles published in 5 years (2015-2019), there are 72/83 journals having an impact index. In which, 42 journals have an index of IF > 0.1; 12 journals have IF > 0.5 and 6 journals have IF > 1.0. Citations are collected from Google Scholar sources, so are often higher than the total number of citations from Web of Science and Scopus sources. The results show that, in addition to journals with international elements, a number of Vietnamese scientific journals are published entirely by internal resources, but have received a very encouraging IF index. Source Vcgate However, in general, the quality of our journals is still inadequate, far from the final group of Q4 international journals. In addition, this year Vcgate also announced the results of the H-index survey of magazines. This index evaluates the degree of integration between publication productivity (quantity) and quality (citation count). Accordingly, the Journal of Advances in Natural Sciences: Nanoscience and Nanotechnology of the Vietnam Academy of Sciences has the highest index (H-index = 53). Assessing the general picture for Vietnamese scientific journals, the Vcgate team found that Vietnam currently has over 600 scientific journals (only in the journal system scored by the State Council of Professors, there are more than 600 scientific journals). 400 journals), of which only 1 journal is indexed in the SCIE (Science Citation Index Expansed) database and 8 journals are included in the ESCI (Emerging Sources Citation Index) of the Web of Sciences; 10 Scopus journals and 18 journals are indexed in the ACI (Asean Citation Index) database. These are very modest numbers compared to other countries in Southeast Asia. According to GS. Nguyen Huu Duc, Vietnamese scientific journals also do not follow international practices, from format to presentation. As for the standard, which is basically only interested in the form of ACI, Vietnam has only passed 18 journals. The editorial board has not yet been able to diversify geographically, the way in which references are presented, the protocol of the minutes, etc., have not been accepted. In the current digitization context, there are only about 115/600 journals published online (only about 19.1%), of which only 83 journals have relatively standardized websites, compatible with other institutions. international data and indexed in the Vcgate system is a very unexpected and sad result. The Vcgate system has been in operation for nearly 5 years, promoting, encouraging and supporting magazines a lot, but hardly make any changes, don’t know the reason for the resistance. GS. Nguyen Huu Duc also said that not digitizing will make magazines self-limiting readers to find them. “Without readers, that means there will be no citations and thus, the journal’s influence on the scientific community is very low,” Prof. Huu Duc said. The process of evaluating journals by the State Council of Professors is too simple and subjective GS. Nguyen Huu Duc said, while the management of productivity and quality of international publications of Vietnamese scientists and S&T organizations can be done very quickly and conveniently through the Web of Science’s database and /or Scopus, statistics and management of publications published in the country cannot be done. How much does the state spend on research, but it is very difficult to manage and analyze accurately and effectively. The list of journals of the State Council of Professors has more than 400 journals, but the selection and quality assessment is still simple, qualitative and subjective, without criteria and selection process. Prof. Nguyen Huu Duc analyzed, the format and presentation format of many scientific journals in Vietnam are arbitrary, inconsistent and inconsistent with international practices. In particular, we do not have a policy to encourage the evaluation of journal quality by quantitative and specific criteria. GS. Nguyen Huu Duc said that only the Ta Quang Buu Prize and the Nafosted Foundation are interested in important factors of the quality of research works through the assessment of two important indicators, namely the prestige of the scientific journal. having high IF index and having the influence of articles of (with high citation index) If the domestic scientific journals have low IF index, the quality is not properly evaluated, it will also affect the quality of the articles. evaluate the quality of the article in particular and the results honoring scientists in general. Works published in scientific journals are the main database and information to evaluate the productivity and quality of scientific research of individuals and organizations, a measure to recognize titles and scientific awards, staff evaluation criteria… If we don’t pay attention to this, we can only evaluate based on the quality of current journals, the consequences will be immeasurable. Therefore, GS. Nguyen Huu Duc recommended that it is necessary to improve the standardization and digitization of the system of Vietnamese scientific journals, to develop a complete system of Vietnamese citation database, to develop a set of criteria and to use database of the citation system to evaluate the quality of journals.

The laboratory where Frankenstein’s monster was born in the movie released in 1931. Photo: Universal Studios Licensing LLC. On a stormy, rainy night, the mad scientist is trying to revive an inanimate monster he created by piecing together parts of an exhumed corpse. After receiving a high-voltage electric shock, it suddenly moved its long, bony fingers and raised one arm. “It’s alive! It’s alive! It’s alive!” shouted the doctor. It was a memorable scene in the Universal Pictures film adaptation of Mary Shelley’s horror novel Frankenstein (or The Modern Prometheus) (first published 1818), starring Mary Shelley. by Vladimir Karloff as the monster. The work became a blockbuster at the box office when it hit the public’s taste for horror cinema, and paved the way for Universal to release a series of iconic monster movies later, including The Mummy (Mummy), Dracula (Vampire), Creature from the Back Lagoon (Creature from the Black Lagoon), … Whether emerging from the swamp, lying in an Egyptian stone coffin or patched up like Frankenstein, … all these monsters are the product of fascination (and sometimes even fear). ) of the community towards science. More than just the creative work of the design and makeup team, the knowledge (which may still be limited) about amphibians, mummification, anatomy … has been borrowed to bring to mind. aghast. Frankenstein movie poster. Photo: Universal Studios Licensing LLC. Shelley was only 18 years old when she wrote Frankenstein while on vacation in Lake Geneva. A special lover of science, she often attends lectures to keep up to date with new trends and research, including the relatively new field of electrophysiology. She was very interested in the work of 18th-century Italian scientist Luigi Galvani, whose initial experiments showed that electric currents could cause (dead) frog legs to twitch, and then used it as inspiration for Dr. Frankenstein. It was also during this period that scientists began to learn about the nature of resuscitation techniques—sometimes bringing back a person thought to have drowned by manipulating air into their trachea and squeezing their abdomen. Shelly’s own mother had experienced such an emergency when she jumped off the Putney Bridge on the Thames, two years before she was born. More than a century later, Universal adapted her novel into a Frankenstein movie, and then released another monster classic: The Mummy (1932) – also starring Boris Karloff as the monk Imhotep, a master of mummification; The film tells the story of a soul punished by being buried alive and accidentally released to return to earth to cause chaos. Before that, in 1922, a team led by British archaeologist Howard Carter opened the tomb of the famous King Tutankhamun, which has remained a mystery for 3,000 years. The event ignited the curiosity and imagination of millions around the world, and sparked a passion for ancient Egypt – decades after the original release of The Mummy. “Monsters have always been a mixture of conscious and unconscious fear.” – Leo Braudy, author of Haunted: On Ghosts, Witches, Vampires, Zombies and Other Monsters of the Natural and Supernatural Worlds , Witches, Vampires, Mummy and other monsters of the Natural and Supernatural worlds) commented. For example, the fear of vampire bites in the movie Dracula (released in 1931) was based on Bram Stoker’s medieval horror novel (published 1897) and the play Dracula ( performed in 1924) by Hamilton Deane and John L. Balderston. Vampire legends existed for hundreds of years before Stoker published the novel, but researchers believe it was deadly mid-19th-century epidemics like cholera and tuberculosis that inspired and spread vampire myths. “In the absence of science, vampire theory is easy to accept. If someone gets TB and spreads it to other family members, they’ll blame the vampires instead of the bacteria.” — Sarah Crawford, longtime curator at the Natural History Museum in Los Angeles , identify. In the movie Creature From the Black Lagoon (released in 1954), designer Milicent Patrick did a lot of research on prehistoric animals and sea creatures to shape the vision for the character “Gill-Man”. She is especially fascinated by the illustrations of reptiles and amphibians that lived about 400 million years ago on Earth. Director Jack Arnold drew inspiration for Gill-Man from the story of the long-extinct coelacanth and thought to be the ancestor of land animals, with unusual fins (which look like like limbs) allowing it to crawl from the ocean to the land. The connection between the sea and land animals, along with the story that the producer heard at a dinner party about a half-human, half-fish creature living in the Amazon River, … all have been brought into creation by Patrick. Figure. Designer Milicent Patrick sketched the sea monster Gill-Man in Creature from the Back Lagoon. Photo: Universal Studios Licensing LLC. Science has not only inspired characters on screen, but has also led to technical experiments and inventions in the field of filmmaking. While staging Dr. Frankenstein’s lab, designer Kenneth Strickfaden – who spent many years as an electrician – devised techniques to simulate ball lightning and electrical discharges. And artist Jack Pierce – the head of Universal’s makeup department – spent eight hours with Karloff on The Mummy, using a mixture made of fuller’s earth and more than 150 feet of ice. gauze. It was the science behind Hollywood’s iconic monsters that made the movies of this golden age even more “horrifying”. In terms of perception, perhaps most viewers know those creatures do not exist. But the thrill and excitement of watching the dramas on the screen made them think, What if they really existed? “Horror movies have been continuously produced, more than any other genre. Because they (monsters and horror things) are, to a certain extent, born within our selves, and as such can never fail,” Braudy said.

Theoretically, the limit of low temperature in the universe is called “absolute zero”, the value is 0 K, converted to the commonly used temperature unit of -273.15 degrees Celsius. And to prove the existence of absolute zero, mankind has had to conduct a lot of experiments over a very long time and the story of this limit value is also quite interesting from a scientific perspective. because when the concept was introduced, no one could conduct experiments near that temperature. But the specific concept of absolute zero was not formed overnight, instead it was studied, observed and concluded by generations of scientists. As early as 1702, the French physicist Guillaume Amonton questioned whether there was a limit to cold. He improved a thermometer that used air and mercury. The volume of air changes with temperature, causing some of the mercury to move to show the scale. The minimum value of the thermometer has a limit, which is the point 0 (according to today’s calculations, it is about -240 degrees Celsius). Until the end of the 18th century, many physicists tried to discover this low temperature limit. In 1785, Jacques Charles, a French physicist discovered the relationship between the temperature and the volume of a gas at constant pressure. In his experiments, he found that in the case of constant volume, for every 1 degree Celsius decrease, the pressure of the gas will decrease by 1/273 of its pressure at 0 degrees Celsius. According to this rule, when the gas temperature drops to -273 degrees Celsius, the pressure becomes zero – vacuum environment. Later, the English physicist William Thomson (ie 1st Baron Kelvin) gave the first formal form based on the summation and speculation of his predecessors about the concept of absolute zero – understood as a state in which the interior of the object can be reduced to zero and completely stop the motion of the molecules. Accordingly, one of the ultimate goals in the field of thermodynamics is a great battle to challenge absolute zero. And of course, this goal cannot be achieved overnight. Michael Faraday. The first major figure in this race was Michael Faraday. By 1845, he had obtained various forms of liquid gases through primary compression. With his technology at the time, he was able to achieve temperatures as low as -130 degrees Celsius. However, during that time he was still unable to liquefy some gases such as oxygen, nitrogen and hydrogen. This was due to theoretical limitations at the time, so Faraday believed that these gases were “permanent gases” and could not be compressed into a liquid state. In the late 1870s, French physicist Louis Paul Cailletet pioneered the production of liquid oxygen and liquid nitrogen, which could be obtained at low temperatures of -183 degrees Celsius and -196 degrees Celsius, respectively. To achieve this, Louis Paul Cailletet applied the Joule-Thomson effect. James Dewar. The next important person was a Scottish chemist and physicist – James Dewar, who would challenge hydrogen, the last “eternal gas” at the time. Scientists at the time expected to be able to produce liquid hydrogen at as little as -250 degrees Celsius. This temperature was an impossible challenge with the technology and equipment at the time, so Dewar had to invented new devices to be able to conduct this research. His plan was to use a gas that could be compressed and liquefied at room temperature, then allowed it to expand and return to a low temperature and then continue to use this temperature to liquefy other gases that are more difficult to liquefy . In this way, after a series of stages, it is possible to reach a temperature low enough to liquefy the hydrogen. But to do that, Dewar was forced to create new equipment and tools for research, which required a lot of money. So Dewar demonstrated some of the unique properties of liquefied petroleum gas to guests in the Royal Society’s laboratory, and used experiments to attract investors’ attention. But the experiment didn’t go well, in 1886, a terrible explosion occurred in a London laboratory, Dewar accidentally mixed liquid oxygen with liquid ethylene and caused an explosion, which subsequently caused the His scientific career was almost over. Soon, however, Dewar produced 20 cubic centimeters of liquid hydrogen through a multistage cascade of methyl chloride-ethylene-oxygen-hydrogen. At that time, the tank had a pressure of 180 atm (atmosphere) and the temperature reached -205 degrees Celsius. Dewar then put liquid hydrogen into the expansion tube and watched the temperature of the thermometer gradually decrease, eventually, he achieved a new record of -252 degrees Celsius, considered to have completed the impossible challenge for the predecessors. Faraday duty. However, shortly after the experiment was successful, a new gas was born – the inert helium gas. Next, Dutch physicist Heike Kamerlingh Onnes went on to undertake this research and built a factory to produce magnetic liquid hydrogen using Dewar’s equipment and miraculously produced liquid helium, reaching temperatures lows of -269°C (4.2 K). At this near absolute zero temperature, many substances will exhibit unprecedented states, including fluid mechanics, electromagnetism and other related properties, which also earned Onnes the Nobel Prize in Physics in in 1913. But so far, no one has been able to conduct an experiment to achieve theoretical absolute zero – the value is 0 K, converted to the commonly used temperature unit of -273. ,15 degrees C.

Recognizing the importance of developing the science and technology market, the Hanoi Party Committee (XVII session) issued Program No. 07-CTr/TU (March 17, 2021) on “Promoting development development of science, technology and innovation in Hanoi city in the period of 2021-2025.” Accordingly, one of the important requirements is to soon build a Hanoi technology trading floor, moving forward. As a national technology exchange, connecting with major technology centers of the world, implementing this task, Hanoi city has assigned the Hanoi Department of Science and Technology to develop the “Project to build a project” building and operating the technology trading floor of Hanoi city”. Technology exchanges play a core role in the development of the science and technology market. In the context that the Fourth Industrial Revolution is taking place strongly, when building the Hanoi technology exchange, it is necessary to ensure all modern features of technology – techniques, most convenient for users. , bringing real benefits to the participants. In addition, there should be a connection with domestic and international exchanges, creating an organic link between research and application of scientific and technological results, commercialization of scientific and technological products. … For the exchange to work effectively, the participation of businesses, scientists, research institutes and universities is essential. The business community needs to improve the quality of governance, build a suitable human resource; actively “shake hands” with universities and research institutes to closely follow market demand and create products with high technology content. At the same time, it is necessary to ensure close association with intermediary organizations and scientists, improve the capacity to absorb, master and apply new technologies. Another important requirement is to focus on the human factor. For the field of science and technology, market development personnel will have more special requirements than other fields, not only needing knowledge of business and law but also knowledge of science, technology… Therefore, it is necessary to have attractive mechanisms and policies to attract a team of good experts, capable of consulting, closely connecting supply – demand; trained human resources with expertise and skills to effectively manage and operate the trading floor. The Hanoi Technology Exchange, which is built and soon comes into operation, will contribute to promoting the science, technology and innovation market. This will be the main driving force for the capital’s socio-economic development in the coming time.

The study estimates that many bird species in Australia, such as the rainbow parrot, number in the millions. Photo: Guardian. The world has about 50 billion individuals of nearly 10,000 bird species, according to a new study that uses public scientific observations to estimate bird populations. Research published in Proceedings of the National Academy of Sciences (PNAS), led by scientists at the University of New South Wales (UNSW), shows that there are six times as many bird species on the planet as possible. human times. There are four species of birds that researchers call the “billion-person club,” with an estimated population greater than 1 billion individuals. These are house sparrows, European starlings, ring-billed gulls and swallows, found in many parts of the world. The researchers estimated the population of 9,700 species, based on hundreds of millions of bird observations recorded by birdwatchers on eBird, one of a number of community science projects on diversity. The world’s largest biome. They combined records with professional scientific observations to develop an algorithm that estimated the population numbers of most species. The team of scientists found that there are relatively few individuals of common bird species, but a large number of rare species. “They can be rare for natural reasons, as they really only live on one island,” said Associate Professor Will Cornwell, a UNSW ecologist and one of the lead scientists on the study. island or the top of a mountain, or they may be rare due to human causes.” Over time, he said, he hopes the models can chart which species are in decline and where conservation efforts are needed. Many bird species in Australia number into the millions such as the rainbow parrot (19 million individuals), the yellow cockatoo (10 million individuals) and the laughing kingfisher (3.4 million individuals). Mr. Sean Dooley, BirdLife Australia’s public affairs manager, is a longtime bird watcher and a contributor to community science programmes. The paper shows the value that people’s observations can contribute to scientific knowledge, he said. “This is a great first step to trying to discover what we have. It will be important if we can continue to do this over time, as we are witnessing a massive loss of wildlife. Research can help us do what is needed to get close to quantifying what’s going on.” By combining bird-watching records and professional monitoring of birds that are the subject of rigorous academic research, scientists have tweaked some of the things that have not been done, said Associate Professor Cornwell. certainly through public science. The model was then applied to birds that have not been studied professionally, he said. The figure of 50 billion birds represents the model’s average estimate for the total number of bird species worldwide. “The really big breakthrough in this study is that we can take the scientific data and the public science data and then fill in the gap for birds that are not expertly studied by scientists,” said Mr. Cornwell. research industry”. There is still some uncertainty in the figures, said Mr. Cornwell, and the researchers plan to refine the model as more professional studies of more species become available. He also said that the study revealed gaps in information due to the importance of scientific attention to birds in developed regions compared to developing countries of the world, and the need to It is necessary to refine global population estimates for all species. According to him, this also shows the role of public science in those efforts. Scientists will conduct another survey in the next few years.

In 2021, Vietnam Science and Technology Day 18/5 has the theme “Science, technology and innovation – Arousing aspirations, creating the future”. The Ministry of Science and Technology requires activities to celebrate Vietnam Science and Technology Day 2021 to be meaningful, practical, economical and effective; strengthen the application of information technology to connect and spread activities to celebrate Vietnam Science and Technology Day 2021 nationwide.

Strengthening the material and technical foundations of S&T enterprises, contributing to promoting the creative potential of the S&T team. According to statistics from the Department of Science and Technology, the province currently has over 3,116 staff members engaged in scientific research and technology development (equivalent to 1,229 full-time researchers, reaching 3.5 people per ten thousand people), an increase 8% compared to 2015; the staff of science and technology in science and technology organizations is 1,706 people (including 201 doctors, 706 masters, 23 associate professors). Human resources with doctoral degrees are mainly concentrated in higher education institutions (universities) (2 higher education institutions have 191 doctorates, 8 research and development organizations have 2 doctorates – at the Institute of Agriculture Thanh Hoa; 29 organizations of science and technology, science and technology services with 8 doctorates). The increase in quantity and quality of human resources in science and technology in recent years have contributed significantly to socio-economic development in all fields of science, engineering and technology. natural sciences, social sciences and humanities… For example, in the field of engineering, technology has researched and applied many technical advances in the production of building materials and handicrafts. , preserving agricultural products after harvest, contributing to diversifying products, increasing productivity, and lowering product costs. The field of medicine and pharmacy has also researched and applied technology in the diagnosis, detection, prevention and treatment of diseases, assessing the situation of a number of diseases in the community, which tend to increase along with changes in the environment, climate and environment. Queen. Typically, open-heart surgery techniques at the Provincial General Hospital; Laparoscopic surgery combined with open surgery to treat non-anal malformations and blood replacement techniques for neonatal jaundice by automatic method at Children’s Hospital; Corneal transplant technique at Thanh Hoa Eye Hospital. In agriculture, a number of high-quality and productive plant varieties and livestock breeds, some advanced techniques have been transferred to the province, such as: fragrant rice, short-term rice, salt-tolerant rice; varieties of maize, green beans, soybeans, peanuts; high-tech products such as Kim Hoang melon, V2 seedless orange… The results of the strengthening of research and application of science and technology in various fields have made important contributions to the development of economic regions. – Social, key economic regions, bringing into play the advantages and potentials of localities. According to the assessment of functional sectors, in general, the S&T staff has actively participated in teaching and scientific research activities at universities, and S&T research at non-business units and enterprises. science and technology industry… In the course of work, the staff of science and technology, on the basis of their capacity and professional qualifications, have been arranged and used by agencies and units to preside over S&T tasks; supporting individuals in S&T activities to participate in domestic and international scientific conferences; participate in programs and projects of investment and cooperation in science and technology; critique the socio-economic development projects and plannings of the province…, contribute to improving the quality of programs, schemes and policies promulgated by the Provincial Party Committee, People’s Council and People’s Committee. Along with that, professional agencies have also built a database of S&T experts to join specialized S&T councils; participate in solving local S&T issues; at the same time, gather and attract many highly qualified S&T staff who have reached the end of their working age to participate in S&T research and training. Besides the achievements, the province’s S&T human resources still have limitations, such as, S&T human resources, although increasing in quantity and quality, are still small, not commensurate with the potential and development requirements. socio-economic development of the province. There is a shortage of leading officials and experts in high-level technology fields. S&T human resources are unevenly distributed, the structure and qualifications are not reasonable by region, region and field of operation; most of them are concentrated in the state sector, urban areas, private sectors, enterprises and rural areas are still low… The spirit of research cooperation and teamwork skills of the S&T force is still limited. Some branches and localities have not yet paid attention to and enlisted scientific human resources from the central government. Policies to attract, employ and reward S&T staff are slow to be renewed, inconsistent and ineffective. Some research works are still limited in quality, with low scientific content… Currently, the fourth industrial revolution and the process of extensive international integration have been posing many problems for the development of S&T human resources of the province in particular and the country in general. The explosive development of interdisciplinary, multi-industry and cross-sectoral technologies of the fourth industrial revolution not only brings opportunities but also poses great challenges for construction and development requirements. S&T human resources. Machines and artificial intelligence replacing human power will lead to the inevitable consequence that the demand for low-skilled cheap labor will give way to the demand for high-qualified human resources. Therefore, more than ever, the requirement to develop S&T human resources becomes more urgent. In particular, the process of comprehensive international integration is demanding that S&T human resources have global skills, update and keep up with new trends in the development of science and technology. Facing difficulties and challenges, in order to create a breakthrough in the development of S&T human resources to meet development requirements in the new situation, it requires functional sectors, committees and authorities at all levels to perform synchronously. many solutions such as raising awareness and renewing thinking for staff doing state management of science and technology. Develop a strategy and long-term vision on the creation of S&T human resources, in which the focus is on developing high-quality S&T human resources in association with the local socio-economic development strategy. Promoting the development of S&T human resources, including training and retraining associated with using and appreciating talents; well implement policies to nurture talents for young scientists. In addition, continuing to pay attention to sending S&T human resources to practice and work at international organizations, research institutes and universities abroad; strengthen bilateral and multilateral international academic exchanges and exchanges. At the same time, building a network of research cooperation with foreign scientists and expanding training programs abroad, so that S&T staff can experience the international academic environment and be trained in activities. international research and development. Along with the well implementation of mechanisms and policies, it is necessary to promote socialization and effectively mobilize investment resources outside the state budget, especially from enterprises for training, retraining and development activities. S&T human resources. Increase mobilization of non-budget investment to develop potentials, especially material and technical foundations of S&T organizations, contributing to improving working conditions for S&T human resources. Thereby, promoting the creative potential of the S&T team, serving the cause of industrialization and modernization of the homeland and the country.

(Source: unctad.org) The United Nations Conference on Trade and Development (UNCTAD) on May 12 announced that it will bring together experts in the meeting of the United Nations Commission on Science and Technology for Development (CSTD) from 17-21. /5 to find out how science, technology and innovation (STI) contributes to a resilient and sustainable recovery after the pandemic COVID-19 . Shamika N. Sirimanne , Director of Technology and Logistics of UNCTAD and who also heads the CSTD Secretariat, said the COVID-19 pandemic has highlighted the urgent need to prioritize STIs for policymaking, resource allocation and international cooperation. However, governments also need to ensure that the developmental benefits of STIs are translated directly into the daily lives of people around the world. It is important for all countries to have equal access to the benefits of life-saving treatments, not only for pandemics but also for diseases related to poverty, future medical emergencies and infectious disease outbreaks, Ms. Sirimanne added. Experts will look at the opportunities offered by technologies some of which are being used to respond to the pandemic, such as artificial intelligence, big data and robotics. While these technologies may enable developing countries to stay ahead of previous technology models and transform economies and societies, these countries – especially the least developed – often not ready to adopt them due to resource and capacity constraints. According to Sirimanne, the COVID-19 pandemic has highlighted many manifestations of deep digital inequality within and across countries. She said proactive policy interventions, mobilization of all stakeholders and international cooperation are needed to guide STI advances towards a resilient and sustainable recovery from the pandemic. In an increasingly digitalized economy and society, the security and accountability of data transactions are critical to building trust and creating disruptive innovations in the technical world. number. In this respect, blockchain technology can be a game-changer, with the potential to revolutionize processes from finance to the pharmaceutical industry, from government public services to humanitarian and humanitarian work. development aid. Blockchain serves as the underlying technology for cryptocurrencies, enabling open (peer-to-peer), secure and fast transactions. The application of blockchain has expanded to include various financial transactions such as online payments and exchange platforms, as well as the Internet of Things (IoT), healthcare systems, and supply chains. “While we have seen a few examples of blockchain’s potential to address sustainability challenges, it is important to avoid hype and ensure that we understand the potential blockchain can have,” said Ms. transformed into an effective answer to the needs of developing countries.” Digital technology has played an important role in addressing the pandemic and enabling resilience in many ways. These include the use of big data and artificial intelligence for public health interventions and the use of digital services to accelerate infection surveillance and testing. Other trends include the use of the Internet and video conferencing platforms for work and education as well as expanding use of e-commerce and online entertainment platforms. “But on the other hand, those who lack affordable connectivity have been severely disadvantaged during this pandemic,” added Ms. Sirimanne. “Other challenges have emerged including misinformation. propagation, privacy and data protection, and network security. CSTD is a subsidiary of the United Nations Economic and Social Council (ECOSOC) and is the United Nations’ focal point for STIs to develop, in analyzing how STIs, including information technology and media, acting as a driving force behind the 2030 Agenda for Sustainable Development.

Increase investment in innovation About 36.4% of the total of more than 350,000 enterprises in Ho Chi Minh City have applied science – technology and innovation. Mr. Le Xuan Dinh, Deputy Minister of Science and Technology affirmed that the creative capacity of Ho Chi Minh City represents a very important part of the creative capacity of the nation. Therefore, it is very important to pay attention to developing the scientific and technological potential of Ho Chi Minh City in the coming period. From the background of science – technology, will make a change in the quality of economic growth of the City. The background of science and technology is reflected in the number of human resources participating in this field, the level of investment in scientific research and innovation activities in businesses and the startup community. If 5 years ago, the concept of start-up and start-up was new, now, this community is growing rapidly in both quantity and quality. Deputy Minister Le Xuan Dinh assessed that Ho Chi Minh City is a pioneer in the country in the start-up movement. According to data from the Department of Science and Technology of Ho Chi Minh City, in the past 5 years, Ho Chi Minh City has become the cradle of direct and indirect support for nearly 1,840 start-up projects in the stages of product completion, completion Adjusting business models, connecting domestic and foreign markets, providing financial advice, developing startup ideas, etc. Along with that, more than 1,000 events were held in the area to connect individuals, organizations, and innovative start-ups with experts, advisors, investment funds and markets through forums. forums, conferences/workshops… “The ecosystem supporting innovation startups in Ho Chi Minh City is the most comprehensively developed in Vietnam, with all components. Therefore, it is necessary to continue to invest and develop this community further”, emphasized Deputy Minister Le Xuan Dinh. Science Development Fund can invest in start-ups Ho Chi Minh City has set a target that by the end of 2025, it will support to improve innovation capacity for 3,000 businesses; support incubating and developing 1,000 innovative start-up projects; supporting the development of 100 innovative start-ups to access venture capital. However, HCMC only supports incubators and events; Direct support activities for start-ups are limited in both direct funding and tax policy. In addition to the start-up group, the promotion of small and medium-sized enterprises to set up funds for science and technology development also needs to be increased. Science and technology development fund is a fund set up by enterprises to invest in scientific research and technological development. This fund is often used to build laboratories; purchase machinery and equipment for research and development (R&D); buy technology copyrights, industrial designs… According to the Department of Science and Technology of Ho Chi Minh City, as of October 2020, in Ho Chi Minh City, only 121 enterprises have set aside a fund for science and technology development with a total amount of more than VND 4,400 billion. . These numbers need to be increased. Leaders of the Ministry of Science and Technology said that in the coming time, the Ministry of Science and Technology and the Ministry of Finance will finalize regulations on the use of science and technology development funds in enterprises. Currently, enterprises often use science and technology development funds to conduct R&D activities, while this fund needs to be used for all activities to support innovation, businesses can use this fund to invest. for start-ups. Therefore, perfecting the regulations on the use of science and technology development funds is also one of the solutions to promote startups.

During those 5 years, the young man observed plants and animals of many different regions, and one of which was especially important, was that he discovered sparrows in the Galapagos Islands and sparrows living in the Galapagos. deep in the continent, although similar, have evolved different biological characteristics to suit feeding in their particular habitat. Later, that guy wrote the book “On the Origin of Species” and introduced the theory of Evolution that shocked public opinion. That boy is Charles Darwin. There are 365 days in a year, and only one day is dedicated to Darwin. However, on the 200th anniversary of his birth, a poll was held and the results were that only 39% of Americans believed in the theory of evolution. At the same time, in England, home of the scientist, The Guardian reported that half of adults did not believe in Darwin’s theory and of those, 22% believed in God’s Genesis. Sole. Millions of Hindus have joined the festival on the Ganges River in recent days, causing an outbreak of the disease. In the Museum of Creation in Petersburg, Kentucky, there is a painting of Adam and Eve sharing a forest with a dinosaur 10,000 years ago, although we think dinosaurs went extinct 65 million years ago while humans are now New era appeared from 200,000 years ago is clear as day. The US and UK are the two leading countries in scientific research. I immediately thought of this story when I saw the pictures of the millions of Hindus in India celebrating the Kumbh Mela festival and then paying the price with the burning cities burning the dead. because of COVID-19. “The faith of the pilgrims will overcome the fear of the virus,” the state premier of Uttarakhand told the press ahead of the festival. Indeed, in just a few days, 3 million people jumped into the sacred Ganges River to bathe, the fear of a new virus that appeared more than a year ago that science warns is nothing compared to the power of the government. boss of the gods for thousands of years. Prime Minister Narendra Modi’s government has also proposed to study the hypothesis that Ganges living water can cure COVID. Yet, just a short time ago, Hindu politicians criticized Muslims for holding large prayers in New Delhi. Actually, they are all the same. Why is there such a thing as unscientific in an age that is thought to be very unscientific? Don’t we often read articles complaining about people’s increasing dependence on technology, on phones, on tablets – and technology is a totem of modern science? Even so, the formula for writing innocuous articles in health care categories is “proven science”—the word “science” is so overused that it becomes inert. But, it seems, the dominance of science and technology is just a fragile outer shell that can always be broken. And people rely on science for the comfort and convenience that scientific discoveries bring, not necessarily for truths or facts about the world. To find out about this strange phenomenon, Professor Andrew Shtulman of the Department of Cognitive Sciences Occidental University devised a test as follows. He invited 150 students who had taken science and math classes to read a few hundred scientific conclusions and asked them to mark the correct ones. A rather surprising result was that it took them a little longer to check the box “Earth revolves around the Sun” than the box “The moon revolves around the Earth”. Both of the above conclusions are clearly correct, but if the Moon revolves around the Earth is something that we can easily perceive, then the Earth revolves around the Sun is something that goes against our common sense and is only possible. know through education. This implies that science’s way to awareness is always resisted by a force of instinctual belief. So, sympathize with the old theologians who thought Copernicus was a heretic, because even the well-educated, raised in a 21st-century environment with bright scientific lights If there is a flash of light on the top of your head, somewhere in your mind there are still remnants of the feeling that the Sun revolves around the Earth, also that the ancient people did not have an inch of tools at hand. Painting “A dinosaur in the garden of Eden”. In a similar test run by University of Maryland psychologist Kevin Dunbar, he also observed blood vessels pooling in the prefrontal cortex when participants validated claims they thought were false. naturally in science, this part of the cerebral cortex is responsible for controlling consciousness. According to Dunbar, this is evidence that the acceptance of some scientific knowledge is not actually about absorbing facts but about suppressing myths. The truth is often hard to swallow, and it holds true in many fields, and even more so in the history of scientific research. The great breakthroughs that completely changed the axis of our knowledge, from heliocentric theory to the theory of evolution, from relativity to quantum mechanics, almost all brought up uncomfortable truths and to With scientific achievements, humanity must abandon the abiding realm of intuition to jump into a crater of flesh-burning truths. But not just dance once. Scientific truth is different from religious truth. The basis of religious truth is certainty, and the basis of scientific truth is doubt. Karl Popper, philosopher of science said that “Truth and certainty must be clearly distinguished. Knowledge is the search for truth. Not a search for certainty.” Or in the words of Richard Feynman, the essence of science is “the hard work of proving you wrong”. No need to take great examples of how Einstein proved Newton wrong and how people question Einstein today, just talk about chocolate, sometimes scientists say that This is a dish that is harmful to health, another time they say it helps to beautify the skin and keep it in shape. Compared to betting on a change like the flash pan of science, to many people, in many matters, religion or intuition seem to be more stable and secure “horses”. Science always puts people in such insecurity. Nowhere is our “me” more vulnerable than in science, because we are always faced with the fact that we are wrong. What’s more, there are many different kinds of truths, and scientific facts are not always better than others. But, there are subjective truths that can push people into a dead end. Like prayer can conquer COVID. Like the Ganges that can wash away diseases. Or as climate change is an exaggeration of zealot scientists. Indeed, according to the survey, a quarter of the population of the US – the world’s closest high carbon emitter – considers climate change a negligible threat! But, even more surprising, in a study published in the journal Psychological Science by Matthew Feinberg and Robb Willer of UC Berkeley, most people when reading dire messages about climate change don’t want to believe it. This is because, that “inconvenient” truth threatens the need to see the world as an organized, stable, and just place where honest workers are rewarded and vandals. will be punished. Meanwhile, climate change creates an equal apocalypse for everyone, guilty or not. Yet, the world is such a cruel place, where the origin of man is nothing more than a divine being, but a fish with finfish, where the Earth is never the navel of the universe, where religious ritual cannot save people from the virus, where the environment is being destroyed irreversibly. And in general, as Carl Sagan, one of the most widely known astronomers to the public, once wrote: “Better hard truths, in my opinion, than consoling illusions.”

1. Bright, clear, puffed fish eyes are a sign of good fish. If the ankle becomes cloudy, never buy it because it is a sign that fish are no longer fresh. In many places, fisheye is edible and is highly valued in cuisine in several countries. Photo: Canva. 2. Oily fish species such as salmon, anchovies, sardines, mackerel, freshwater salmon and tuna are rich in brain-healthy omega-3. Specifically, in 100 grams of salmon, there are nearly two grams of omega-3, while with mackerel, this number is up to more than 2.6 grams. Meanwhile, the recommended daily intake of omega-3 fats is 1.1 grams for women and 1.6 grams for men. Photo: Canva. 3. With oily fish that are rich in nutrients and omega-3s, it’s best to cook them gently. In fact, how to prepare or cook fish can affect the amount of nutrients left in a dish. Canned fish causes a significant loss of omega-3 content; Cooking at high temperatures such as frying or frying can degrade or oxidize omega-3s. Ideally, the steaming or baking method should be used to prepare oily fish. Photo: Canva. 4. There is a huge difference between industrial super frozen fish and home frozen fish. If not eating right away, consider buying frozen fish. Because most household freezers are low-powered, ice crystals form a lot, which can break down proteins in fish. Meanwhile, industrial super-freezing is carried out in closed cycles, often starting right on the fishing boat to prevent fish damage. Photo: Canva. 5. To start frying fish, first place the pan on the stove on a medium heat, let the pan heat up for at least a minute and then pour the oil. When cooking, fry the fish only when the oil has started to simmer, so the fish will be delicious without drying out. Photo: Canva. 6. Cooking fish meat by frying method is one of the simplest and most effective ways. Compared to boiling, the frying temperature is up to 75% higher because the oil has a boiling point higher than the boiling point of water. So frying is a quick cooking technique. Photo: Canva. 7. In cooking, there are two different methods of cooking fish and they give very different results. With the “en papillote” method, the fish is covered before placing in the oven. They will ripen by the water inside the fish meat. The dish will be soft and succulent and infused with spices. The second method of baking whole fish without covering makes for a great dish because 140 degrees C will crunch the outer layer of the fish while the inside cooks slowly and retains moisture. Photo: Canva. 8. Blanching fish can prevent the dish from drying out because the water cannot evaporate from the surface of the skin. A common blanching mistake, however, is to boil the water too much. At that time, the fish’s outer layer may quickly ripen and flake off. You can cover the fish with water so that the fish is fully cooked at a temperature of 71-85 degrees C, when the water is boiling. Photo: Canva. 9. When frying fish at high temperature, the water will evaporate and make the fish skin become golden brown. This is because when the heat reaches 140 degrees C, the Maillard reaction is activated, amino acids and sugars react with each other to brittle fish skin and create brown color and delicious taste. Photo: Canva. 10. There is a common concern among home chefs when thinking about poached fish is the fear that they will become soggy or soggy if they soak for a long time. However, it is true that 70% of the fish’s muscle cells are water, so they cannot absorb any more water. Blanching prevents the fish from drying out as the water cannot evaporate from the surface of the fish. Photo: Canva.

However, one sense that humans can soon master, is bat-like echolocation. Sixth sense experiment According to the Popular Mechanics Scientists in Japan have tested this ability in a laboratory, proving that humans can use it echolocation , or the ability to sense echoes for navigation. This ability helps people recognize the shape and rotation of many objects. Thanks to that, people can “see” in the dark. When the volunteer presses the tablet, a synthesized echo is emitted from the amplifier speaker (red line). The sounds obtained with the binaural are 1/8 of the original pitch by reducing the sampling frequency, which is transmitted into the volunteer headphones (green line). Photo: Miwa Sumiya. As bats fly around objects, they emit intense sound waves from different angles and bounce off at isolated intervals. Thanks to that, this tiny mammal can determine the topography, texture or movement of an object. According to Dr. Miwa Sumiya, if humans were able to perceive the patterns of time-changing sounds similar to bats, they could see the world in new ways. Dr. Sumiya, a researcher at the Center for Nerve and Information Networks in Osaka, Japan and was the first author of a paper to appear on Plos One on this topic. “Testing that humans are capable of detecting multiple environments via sound waves could add a new step in understanding the complexity of the human brain,” Sumiya said. According to Sumiya, humans have the ability to further understand the perception of other species (such as bats) by comparing with knowledge gained in echolocation studies of humankind. To test this theory, Mrs. Sumiya’s group made a meticulous arrangement. In one room, the researchers gave volunteers a pair of headphones and two tablets, one that produced a calibrated signal using a synthesized echo, the other to listen to pre-recorded echoes. . In room 2, only the strangely shaped 3D axes stand in one place and rotate around themselves. When prompted, 15 volunteers turned on echolocation signals from their tablets. The sound waves emit each beat, travel to room 2 and hit the 3D axes. Participants need a little bit of imagination to convert sound waves into a certain object. Sumiya explained that the synthesized echo-locating signals used in this experiment were high-frequency signals up to 41 kHz, which cannot be heard by humans. Dolphins are also a mammal that uses echolocation to detect and hunt. Photo: Getty Images. Researchers used a humanoid (1/7 the size of a real skull) to “hear” the sound in room 2 before passing it on to volunteers. The fake head is equipped with 2 microphones attached to the two ears and creating a 3D resonance. The sound output is quite similar to the surround sound experienced in movie theaters. Reducing the frequency of the echoes in both ears enabled volunteers to hear “with the feeling of being heard in real space”. Many people like to listen to podcasts or watch videos with headphones to create surround sound and give a tingling sensation in their ears. This is called the Autonomous Sensory Meridian Response, or ASMR. Result Finally, researchers and volunteers guessed whether echoes were coming from stationary or spinning objects. At the end of the experiment, the volunteers were able to accurately identify two pillars thanks to the time-varying echolocation signals emanating from them. Identifying clue is thanks to the pitch and timbre. However, it was difficult for them to discern the shape of the standing pillars. Sumiya’s group study is not the first to test the ability of human echolocation. Previous studies have shown that blind people can use mouth-clicking sounds to see 2D objects. However, Ms. Sumiya said her experiment was the first to specifically explore the ability of echolocation to change over time. The researchers said their work is evidence that both humans and bats are capable of decoding objects through sound. In the future, engineers could apply this technology to wearable devices such as watches or glasses to improve how visually impaired people can navigate the world, except for headsets.

Being passionate about plants and sticking to plant research, especially flowering plants, TS. Do Van Truong , Vietnam Museum of Nature, Vietnam Academy of Science and Technology, famous scientist for many discoveries for new species, dedicates his youth to focus on research in this field. TS. Do Van Truong on a field trip. Along with the professional work such as biodiversity research, plant resources … an important part of the TS’s indispensable work. Do Van Truong and colleagues to find and identify new species for science. And each new finding is published is a special story with lots of sweat and tears. TS. Do Van Truong recalled that in 2017, when he was on a field research trip in Kom Tum, he was on his way back to Nha Trang and happened to be surfing on Facebook and saw a young friend posting a picture of a tree wildly. See photo, TS. Do Van Truong saw that this was a very strange tree, never seen before. Immediately exceed 200 km to enter Binh Dinh area and approach strange trees. Arrived, TS. Do Van Truong received guidance from a local resident and confirmed that it only took half a day to both go and return. So at 10:00 a.m. the group set off with their inventory of a few loaves of bread for a makeshift lunch in the woods. As expected, about 2 hours later, we have reached the place where there are strange trees. The team was very happy and spent an hour observing, describing, recording, and collecting samples of strange plants to study. Due to the fact that indigenous people have a clear understanding of the terrain in the area, the group decided that when they returned, they would not return to the old road but approach another forest area to find a trail back to the village. However, the more you get lost. 5:00 pm, darkness collapses, only 2 small biscuits left, the phone has no waves, cold weather and small rain. The group decided to stop and approach the nearest mountain to hope for phone waves, because according to many years of experience in the jungle, TS. The more you know, the more you get lost and lose your energy. Hunger, cold, and even panic occasionally rekindled. 5am ​​the next morning, TS. Do Van Truong and his colleagues decided to go back to the old way. The group went continuously for 5 hours to reach a large stream flowing back to the village and met two communal militiamen who were on a mission to “find stray scientists”. As it turned out, during the night, many of the people in the village were unable to sleep because of their anxiety. The police, the military, even professional hunters were mobilized to find you. “It was a memorable trip in life. Hungry, thirsty, arriving in tattered clothes. Luckily, this strange tree was later researched and identified as genus (Michaelmoelleria F.Wen, YGWei & TVDo, gen. Nov.) And plant species (Michaelmoelleria vietnamensis F.Wen, ZBXin & TVDo, sp. nov.) new to world science ”Dr. Do Van Truong said Michaelmoelleria vietnamensis F.Wen, ZBXin & TVDo, sp. nov. The feeling of a winner TS. Do Van Truong added a memory, that is in 2018, during a trip to investigate and survey the flora of Vu Quang National Park (Ha Tinh), on the way back, colleagues discovered a tall vines. , beautiful flowers immediately take it and send it to you. At this time, TS. Do Van Truong is working in China, when he received the photo, he had a premonition that this was a very strange plant in his group. TS. Do Van Truong on a field trip When he returned home, he decided to find this vine. By the end of 2020, TS. Do Van cooperated with Vu Quang National Park to conduct a field trip to an area where strange plants were recorded before. This is a dangerous terrain and very far from the ranger station, so the group decided to sleep in the forest with determination to “hunt” with strange trees. At 6 am, the group will start their journey from the ranger station until 4pm to reach the desired area. However, within a radius of 1 km where colleagues used to take pictures, PhD. The red-eyed field still cannot see vines or regenerated seedlings of strange plants. TS. Truong commented that it is possible that individuals of strange plants have died due to the strong impact of previous droughts. At 5:30 it was dark, the group decided to camp, rest and drink wine for the sad: “Quiet space, darkness covered, and depressed mood. That feeling, I still remember until now ”, TS. Do Van Truong recalls. 7:30 the next morning, TS. Do Van Truong decided to search again, in the hope that the tree has flowers, that is to bear fruit, and is a source of seeds for regenerating seedlings. This is an area where the forest is not affected, definitely the trees are just around somewhere. He went back and forth many times, digging through the forest ropes, he finally found, it was a tree trunk lying hidden in a large cluster of trees. “At that time, she was sweaty and tired. But the feeling of victory is great ”. Up to now, on the basis of the results of analysis and research, PhD. The school has confirmed that this is a new plant species for world science, named: Aristolochia vuquangensis TVDo, sp.nov. Aristolochia vuquangensis TVDo, sp.nov. Fruit for efforts Hard, even dangerous, however, TS. Do Van Truong has received “sweet fruits”. In the period 2010-2020, PhD. Do Van Truong and colleagues have discovered and described 1 genus and 28 new species of higher plants for world science, of which 1 genus and 22 species were discovered and described in Vietnam. Also in the period from 2010-2020, PhD. Do Van Truong and colleagues have published a total of 26 scientific works describing new plant species in international journals. In which, 23 works were published in prestigious international magazines. According to TS. Do Van Truong, research to discover and describe new species for science, especially newly discovered species in Vietnam is of great significance. The first is to highlight the role and importance of biodiversity in Vietnam, which is a solid scientific basis for classification for conservation and application research. learning, probiotics …). In addition, scientists initially researched, propagated and successfully conserved a number of new species. This is an important basis to conduct research activities to develop precious plant genetic resources in Vietnam for the needs of use (medicinal herbs, ornamental plants, food for insects …), making an important contribution to the process. process of conservation and sustainable development of wild plant species. There are many concerns Being enthusiastic and pursuing plant research for many years, PhD. Do Van Truong said that he himself still has a lot of concerns. “Vietnam is a country with high biodiversity, but we do not have an in-depth research program on Vietnam’s flora. This is very unfortunate. We hope that there will be a unit with sufficient expertise and international relations to conduct a methodical and extensive research on the flora of Vietnam ”, PhD. Do Van Truong confided. One more concern of TS. Do Van Truong, that is attracting young people to participate in plant research. Part of the reason is that basic research is always a “silent” industry that has not been given adequate attention and investment. Moreover, the difficult life makes many young people who graduated from school are not eager to do research but turn to another direction. “If this situation continues, not knowing after 10-20 years, who will we marry to continue our work”. Invite readers to watch the video: Urgently clarify the cause of the son-in-law shooting, the wife’s parents died and then committed suicide. Source ANTV.

Fast sleep according to the military method The method below can take up to 120 seconds to complete at the beginning, but the practitioner should be able to sleep from the first 10 seconds later. According to experts, this method has helped pilots practice sleeping habits in 2 minutes or less. This easy military method of sleeping is really effective, even if they’ve just had a cup of coffee or have loud gunshots in their ears. Doctor, Doctor Truong Hong Son – Vietnam Institute of Applied Medicine – Photo: Hoa Ngoc Van To apply the military fast sleep method, take the following steps: Relax the whole facial muscles, including the muscles inside the mouth; relax your shoulders to relieve tension and let your arms drop to your sides; Breathe out gently, relax your chest; relax legs, thighs and calves; Clear your mind with gentle relaxation images. If you still cannot sleep, tell yourself and repeat: “Stop thinking, stop thinking …”, your head will become heavier and may fall asleep within 10 seconds. This is a scientifically proven method of fast sleep to be effective. How to quickly fall asleep using the 4-7-8 breath method In the first times of this 1-minute quick nap, it can take up to 2 minutes to see the effect. This is a method of combining breathing exercises while meditating with recall or imagination. To prepare to learn this quick nap, put the tip of your tongue on the palate and behind your front teeth. Keep your tongue there all the time “lull up” and gently pamper your lips as you learn to breathe, then do the 4-7-8 breathing method as follows: Let your lips open slightly and make a whistling sound when breathing out through your mouth, then close your lips and inhale gently through your nose, counting from 1 to 4 in your head. Next, hold your breath for 7 seconds then exhale for 8 seconds with a “Om om um um” sound. This is a way to simulate the sound of the “Om” mantra in yoga, which is responsible for eliminating toxins and purifying the pure gas inside the body. This mantra also helps make it easier to fall asleep by pushing out of the body the negative emotions inside it. Avoid breaking the stillness at the end of each cycle. Try to practice this quick sleep without thinking anything. How to quickly sleep with a method of muscle relaxation The general rule of thumb for a fast sleep with muscle relaxation is to alternate muscle tension and relax parts of the body. Follow the steps: Raise your brow as high as possible for 5 seconds, this will help stretch your brow muscles. Instantly relax muscles and feel relieved, wait 10 seconds. Smile wide, make cheeks stretch, hold for 5 seconds and relax. Pause for 10 seconds. Squint with half-closed eyes and hold for 5 seconds, relax. Then pause for 10 seconds. Tilt your head back slightly to comfortably look up at the ceiling, hold for 5 seconds, and relax as your neck falls back onto the pillow. Pause for 10 seconds. Just like that, continue the technique of stretching and relaxing down to the rest of the body, from the biceps to the chest, thighs to the feet. Let yourself fall asleep even without completing the stretching and relaxation of the rest of your body. When working on muscle relaxation techniques, focus on feeling the most relaxed of your body as a whole. How to quickly sleep in 120 seconds If the military method of fast sleep, 4-7-8 breathing and muscle relaxation are not effective, you can try a combination of 3 methods to help sleep within 2 minutes including: Tell yourself that you “need must stay awake “; Imagine a peaceful space; Do acupressure to sleep better. Telling yourself that you “need to stay awake” is a method based on the “paradoxical intent” principle that simply makes it easier to fall asleep. When you find it difficult to sleep, do what you are doing bad like learning English, finish the job at the company … Visualizing a peaceful space is the easiest way to fall asleep. According to the study, scientists believe that people who enter imaginary images fall asleep faster. Imagine yourself relaxing in a peaceful space like the beach in the sunset, a field of lavender flowers radiating gently, the rice field blowing in the wind … In addition, there are several methods of acupressure to help you sleep well when you have insomnia. This method can be found on the internet or through video medical instruction channels. However, in addition to the above methods, it is necessary to combine a healthy diet and a regular exercise schedule to see the effects. The most important thing is to learn how to let go of all your troubles before going to bed to get a good night’s sleep each day.

This is by doing small things like planting a tree, being environmentally friendly by reducing the waste load or reusing it. The stories in the book have a specific interaction for children to understand why we have to classify waste, reduce using plastic, love water …

In the midday of April 23, the “A-share first-quarter performance pre-increasing king” Hotview Bio once again rose by the daily limit, the stock price reported 174.13 yuan per share, and the total market value exceeded 10 billion yuan. In the past 9 trading days, there were 6 daily limits, and the stock price has increased by more than 3 times since April.

As the king of pre-increasing A-share performance in the first quarter, Rejing Bio realized a net profit of 660 million yuan attributable to the parent in the first quarter, a year-on-year increase of about 1,200 times. Regarding the reasons for the pre-increasing performance, Hotview Bio issued an announcement stating that the company’s two new coronavirus antigen detection kits have been certified by the German Federal Institute of Medicines and Medical Devices and can be sold in German supermarkets and pharmacies. Affected by the performance forecast, from April 12th to April 19th, Hotview Biotech gained 5 daily limit on 6 trading days.

It is worth noting that the company’s major shareholders violated regulations to reduce their holdings after the stock price of Hotview Biotechnology soared. Rejing Bio announced that in October 2020, shareholders of Fortune Group announced that three companies will reduce their holdings, and the reduction plan will expire on April 9. During the period, a total of 4.57 million shares were reduced, accounting for 7% of the company’s total share capital. The price of the reduction is maintained at around 40 yuan, and the amount of the reduction is 194 million yuan.

After the expiration of the shareholding reduction, the three Dachen companies are still reducing their shareholdings. Rejing Bio issued an announcement on this matter, stating that due to the negligence of the staff to reduce the shareholding procedures, the three companies of Dachen Group reduced their holdings of 1.368 million shares through a centralized bidding transaction, accounting for 2.2% of the company’s total share capital, and 2.2% after the stock price soared. The reduction in holdings is also close to 100 million yuan. (Text | AI Finance and Economics Zhu Quanhong)

Both the “social division of labor theory” and the “big brother” construction theory are in the past. In modern society, what is needed is a combination of liberal arts and sciences, and integrated talents who can comprehensively use all aspects of knowledge.

Rather than indulging in the unrealistic disputes over the arts and sciences, it is better to think about whether our current education has cultivated children’s ability to face modern issues. The comprehensive educational significance of the liberal arts and sciences is to help students build a variety of frameworks for viewing problems, consider the rationality of solutions from different perspectives, weigh the pros and cons of all parties, and assume their responsibilities.

Recently, the official WeChat account of the central bank published a working paper entitled “Awareness of my country’s Population Transition and Countermeasures”. The paper was written by four PhDs in economics. One of the reasons for the middle-income trap is that there are too many liberal arts students”, causing an uproar.

This view has caused many netizens to discuss the pros and cons of liberal arts students in personal job promotion, social and economic development, and so on. Liberal arts students have a long history of despising each other. There is a saying in “Siege” that “science students look down on liberal arts students”. Under the background of pursuing the development and revitalization of science and technology, science students often occupy a certain high ground, but the right to speak is usually in the hands of liberal arts students. The two sides are divided into camps, you come and I go, arguing against each other. However, are things really so clear-cut?

Not to mention that the economics studied by the four Ph.Ds is regarded as liberal arts in the current discipline classification of most universities. If their aforementioned views are valid, does it mean that the four PhDs in economics themselves are “superfluous”? Just from the current situation and trend of education reform, how do researchers accurately define liberal arts students and science students? Dividing talents into liberal arts students and science students, and judging whether talents are beneficial to national development based on their disciplinary background is worthy of reflection.

▌The current education trend is that the arts and sciences are not divided into subjects

The division of liberal arts and sciences is an education system implemented in some countries and regions. The teaching courses are divided into liberal arts and sciences, allowing students to choose and conduct separate education. In the context of Chinese or the Chinese character cultural circle, the liberal arts (or the full name of humanities and social sciences) refers to the subjects of politics, economics, culture and other related knowledge related to human thoughts; while the sciences are actually “science and engineering” The abbreviation is biased towards natural sciences and technology, where science includes mathematics, physics, chemistry, biology and other natural science subjects. The engineering disciplines include engineering disciplines such as machinery, civil engineering, and architecture. Although it is a collective term, there is a difference between science and engineering. The science subjects focus on theoretical research, and the engineering subjects focus on practical operations. Or in other words, “science trains scientists, engineering trains engineers.”

The sub-discipline of liberal arts and science is a historical product. Lu Xiaodong, the deputy dean of Yuanpei College of Peking University, pointed out: “The ideological foundation of the sub-discipline of liberal arts is Adam Smith’s theory of social division of labor. , It can improve the efficiency of the whole society. The direct reason for the implementation of liberal arts and sciences after the founding of the People’s Republic of China is that the new China fully imitated the era of the former Soviet Union’s “big brother”—the college entrance examination system and the higher education system are also inevitable.”

More than two hundred years have passed since the publication of the book “The Wealth of Nations”, which put forward the “Social Division of Labor Theory”. With the maturity of modern pedagogy, the development concept of putting people first rather than treating people as tools is deeply rooted in the hearts of the people, and the division of arts and sciences has been more and more questioned. The current education system has begun to reform such divisions, such as in the college entrance examination. Cancel the traditional distinction between liberal arts and science.

With the expansion of the pilot reform of the college entrance examination, Shanghai and Zhejiang have no distinction between liberal arts and sciences since 2017; Beijing, Tianjin, Shandong, and Hainan have no distinction between liberal arts and sciences since 2020; Fujian, Hubei, Jiangsu, Guangdong, Hunan, Hebei, Liaoning, Chongqing Starting from 2021, the reform will break the limitations of simple division of liberal arts and sciences, and give students more autonomy in subjects through the “3+1+2” model. It can be said that the direction of the comprehensive reform of the college entrance examination is to abolish the restrictions on the traditional arts and sciences, encourage students to explore personalized learning paths, and cultivate more comprehensive talents.

As far as the IB International Baccalaureate Organization course I teach, the academic training at the high school level also does not simply distinguish the characteristics of students’ liberal arts and sciences, but requires students to choose six specific courses from six subject groups for research. The subject groups are language and literature (mother tongue), language acquisition (second language/foreign language), individual and society (such as history, economics, philosophy, etc.), science (physics, chemistry, biology, etc.), mathematics, and art. Taking into account the characteristics of different individuals, students can choose an additional course in the first five subject groups to replace the art course.

This kind of curriculum is similar to the elective mode of American College of Arts and Sciences, aiming to cultivate students’ comprehensive ability. In order to open up students’ understanding and knowledge of different disciplines, TOK Theory of Knowledge will guide students to reflect on the nature of knowledge and explore how humans obtain knowledge that we take for granted (how we know what we claim to know).

In fact, before the division of liberal arts and sciences in middle schools, many majors were already integrated in liberal arts and sciences when enrolling students, such as journalism, economics and law (where the four Ph.Ds are located) and so on. For some traditional liberal arts majors, practitioners have realized the significance of interdisciplinary research and study for the cultivation of compound talents.

Taking the School of Journalism of Fudan University as an example, the “2+2 undergraduate teaching and training reform” implemented in 2018 allows undergraduates to rely on eight majors including computer information technology for wide-caliber training in the first two years, and enter the training of journalism and communication in the next two years. , So as to better adapt to the needs of the current development of the news dissemination industry. It is conceivable that a news talent who is good at new media technology and data analysis cannot be simply defined as a “liberal arts student”. Economics requires not only the use of a large number of mathematical tools for data analysis, but also a series of traditional “liberal arts” content such as consumer preferences, macro planning, and information feedback. Not to mention the current minor and dual degree policies provided by the university, allowing students to cross the boundaries of liberal arts and sciences and learn what interests them outside of their majors.

▲ “Two Cultures” is the first part of an influential speech delivered by British scientist and novelist CP Snow in 1959. In the same year, it was published as “Two Cultures and Scientific Revolutions” in book form. The main argument in the book is that science and humanities, which represent “the intellectual life of the entire Western society,” have been divided into “two cultures”, and this division is the main obstacle to solving world problems.

▌Art and science sub-subjects do not meet the needs of realistic problem-solving

Under the modern background of diversified demand for talents and encouragement of individualized development and training of students, the simple division of students into liberal arts students and science students, and even the judgment that “the liberal arts students misunderstood the country” has already ignored the context of the times. As mentioned earlier, both the “social division of labor theory” and the “big brother” construction theory are in the past. In modern society, what is needed is a combination of liberal arts and sciences, and integrated talents who can comprehensively use all aspects of knowledge.

The current world is facing unprecedented changes, especially when the shadow of the new crown pneumonia epidemic still looms over the world. The work and lifestyle of billions of people have changed, and the global economic recovery is still full of uncertainties. Problems such as medical support, drug R&D and distribution, accurate transmission of information, the impact of the epidemic on the economy and the intensification of the gap between rich and poor in society, racial conflicts and even conflicts caused by the reduction of living space are not a single traditional liberal arts or science knowledge that can be easily resolved. of.

Take the recent vaccination issue as an example. The development and experimental production of medical vaccines are based on scientific knowledge, and the promotion and management and distribution rely on language and social science methods. Individuals’ fear and rejection of vaccines cannot be resolved automatically by the experimental data of vaccines, and they need to be communicated and persuaded through empathy cultivated in the humanities.

Similarly, the progress of global epidemic prevention cannot be automatically succeeded only through the sales of pharmaceutical companies’ products, but also through coordination within the country and mutual assistance and cooperation between countries to ensure the fair distribution of vaccines. It can be seen that in solving problems, the social humanities and the science and engineering experimental disciplines are not originally opposed or the relationship between two alternatives, but to cooperate to achieve their goals.

▌What kind of people and abilities should be cultivated by education?

Rather than indulging in the unrealistic disputes over the arts and sciences, it is better to think about whether our current education has cultivated children’s ability to face modern issues.

In the current era of high-speed information, when the boundaries of knowledge continue to expand, global challenges are everywhere. In education, it is better to cultivate students’ “meta” ability to analyze problems, solve problems, and express effectively than masters of liberal arts and sciences. Specific knowledge is more important.

When children are studying science subjects, the teacher no longer keeps an eye on test scores, repeats exercises, and strengthens the application of formulas in different exercises, but allows students to train their thinking methods on the basis of knowledge and guide them to face For complex problems, transfer the experimental methods you have experienced in scientific learning, such as variable control and observation, and refine seemingly indissoluble complex problems into manageable modules, so as to think one by one and break each one. Maybe this is the case. The meaning of science learning.

Students can and must experience scientific experiments in person to truly appreciate the simple and orderly scientific process: observing phenomena, asking questions, setting hypotheses, testing hypotheses, and sharing results. Learn what is evidence-based, scientific thinking and logic. In the cycle, human cognition is constantly updated.

However, in the process from analyzing problems to solving problems, especially when making decisions, the data and facts contained in scientific discussions should not be the only yardstick. Even the efficiency of input and output in economics is not the entire decision. According to the basis, it is also necessary to take into account the ethics and humanistic care cultivated by the liberal arts.

Taking the discharge of nuclear waste water from the Fukushima Daiichi Nuclear Power Plant into the sea as an example, the report submitted by TEPCO to the World Atomic Energy Agency (IAEA) included deep underground pumping, mortar solidification treatment and then burial, electrolysis, evaporative release, The cost of these five plans for discharging into the sea ranges from tens of billions of yen to hundreds of billions of yen. In contrast, discharging the sea only requires a few billion yen. If we do not learn from the historical nuclear accidents of the United States, the Soviet Union and other countries, and do not consider the safety of marine life and the human rights of citizens, and only make this choice from the perspective of price, it will inevitably bring about possible nuclear pollution and certain international tensions. More far-reaching issues. The comprehensive educational significance of the liberal arts and sciences is to help students build a variety of frameworks for viewing problems, consider the rationality of solutions from different perspectives, weigh the pros and cons of all parties, and assume their responsibilities.

Some people may say that thinking about issues forward and backward will lead to hesitation, indecision, delay in making decisions, and missed opportunities for action. But this is exactly what scientific disciplines can strengthen the balance. It can help people make decisions when information is uncertain. New scientific theories always require new experimental designs for continuous testing, and creating new experiments can often activate original cognition, improve theoretical connotations, and extend more experiments in the future to help us understand current problems.

Science is precisely the process of setting models, making decisions, and constantly improving on the basis of inadequate information. Just like the choice when life is at a fork in the road, no one can fully grasp the information, but if the individual can master the analysis and action, reflect on the improvement Ability, face every choice with a positive attitude, so you don’t have to worry about one step wrong or wrong step. This is scientific literacy and scientific mentality.

In addition to individual choices, important decisions of companies, society, and the country often require collective decisions. At the same time, many decisions involve multiple interests, and any decision must have its beneficiaries, losers, and cost payers. Then, how to weigh the interests of all parties and how to persuade different people to compromise with each other to achieve the greatest common divisor. It will inevitably test the individual communication and expression skills cultivated by the humanities, the empathy and coordination of the interests of all parties.

We often agree that the training basis of the former lies in the reading and writing of language and literature subjects. Through studying various writing methods and content, students explore their expression effects, thereby improving their accurate expression level. The latter needs to broaden one’s horizons and perspectives and achieve diversity and tolerance through reading in history, politics, and literature.

However, we ignore that the quantitative thinking and argumentation methods that scientific disciplines value can also help to improve the individual’s ability to communicate and persuade: how to use quantitative data to analyze and persuade others to accept their opinions? How to distinguish the validity of the argument and avoid selective data use or imperfect logical chain? How to explain the benefits and costs of all parties reflected in the data? If researchers can develop such abilities in the process of receiving liberal arts education, they will not easily come to the conclusion that “one of the reasons Southeast Asian countries fall into the middle-income trap is that there are too many liberal arts students”.

Tesla releases data for 1 minute before the brake accident of Zhengzhou car owners

Tesla provided data from one minute before the vehicle accident and provided a text description. The full text of the text description is as follows:

When the driver stepped on the brake pedal for the last time, the data showed that the speed of the vehicle was 118.5 kilometers per hour. Within 2.7 seconds after the driver stepped on the brake pedal, the maximum brake master cylinder pressure was only 45.9 bar. After that, the driver increased the stepping on the brake pedal, and the brake master cylinder pressure reached 92.7 bar. The front collision warning and automatic emergency braking function were activated (the maximum brake master cylinder pressure reached 140.7bar) and played a role, reducing the amplitude of the collision. 1.8 seconds after the ABS was applied, the system recorded the occurrence of the collision. After the driver stepped on the brake pedal, the vehicle speed continued to decrease, and before the collision, the vehicle speed was reduced to 48.5 kilometers per hour.

To sum up, the vehicle is running at a higher speed, and the driver starts to depress the brake pedal with less force. After that, the automatic emergency braking function is activated and takes effect, increasing the braking force and reducing the impact of the collision. The driving system is normally involved in the work and reduces the speed of the car.

In addition, with regard to the condition of the vehicle 30 minutes before the accident, Tesla stated this: In the 30 minutes before the accident, the driver drove the vehicle normally and had more than 40 records of depressing the brake pedal. The vehicle has repeatedly stopped more than 100 kilometers per hour and stopped repeatedly.

Chanel loses a trademark dispute with Huawei, the court: the signs of the two sides are different in the direction of the semicircle, there is a difference in visual difference

Recently, Caijing Life was informed by the BBC that the French luxury brand Chanel had lost a trademark dispute with Huawei.

It is understood that this dispute began in 2017, when Huawei applied to the trademark agency the European Union Intellectual Property Office (EUIPO) for approval to register its computer hardware trademark, which is composed of two vertical semicircles intersecting.

Chanel objected to this, saying the design was similar to its “double C” trademark. Since then, the Trademark Office rejected Chanel’s objections in 2019, saying that there are no similarities and it is unlikely to cause confusion in the public mind.

Subsequently, Chanel again challenged this ruling in the Luxembourg court. The court rejected its appeal in Wednesday’s ruling and stated that the two signs have different semicircular directions and visually significant differences.

Image source: Shanghai Stock Exchange official website

In the second round of inquiries on the Science and Technology Innovation Board, the Shanghai Stock Exchange is mainly concerned with the disclosure and verification of company shareholders’ information, R&D expenses and science and technology attributes, legal compliance of overseas subsidiaries, market space and industry development direction, industry policies and trade policies, and customers There are 14 questions in total.

Specifically, the Shanghai Stock Exchange requires Kuaike’s e-sponsor and issuer’s lawyers to verify and explain: (1) Whether there are any stock holdings in the issuer’s historical evolution, and if so, whether it is legally dismissed, whether to verify and disclose the reason for its formation and evolution. Circumstances, dissolution process, whether there are disputes or potential disputes, etc.; (2) Whether the issuer’s disclosure of shareholder information is true, accurate and complete.

Kuaike Electronic Reply: After consulting the issuer’s industrial and commercial registration information, the questionnaire issued by the shareholder, the letter of commitment, the shareholder’s capital contribution or payment certificate, the bank flow of the major shareholder during the reporting period, and the shareholder Fuende Xingyu’s fundraising account collection details and interviews The relevant shareholders of the issuer confirm that there is no proxy holding of shares in the issuer’s history. As of this issuance, the issuer is 48 million yuan, and the issuer has experienced 2 capital increases and 3 equity transfers.

After verification, the issuer’s capital increase and equity transfer in the aforementioned historical evolution did not exist on behalf of stock holdings, and the shares were clear and clear, and there were no disputes or potential disputes.

Regarding the surprise share purchase, the Shanghai Stock Exchange requires the sponsor and the issuer’s lawyers to verify and explain: whether new shareholders have been added through capital increase, share transfer, etc. within 12 months before the declaration; if so, whether to verify and disclose the basics of the new shareholders in the prospectus The circumstances, reasons for the share purchase, share price and pricing basis, whether the new shareholder has an associated relationship with other shareholders, directors, supervisors, and senior management of the issuer, the new shareholder and the intermediary institution of the issuance and its principals, senior management, and economic Whether there is an affiliated relationship between the office staff, whether there is a situation of holding shares on behalf of the new shareholders, etc.

Kuaike Electronic responded that according to the issuer’s industrial and commercial registration information, capital increase agreement, capital contribution or transfer payment voucher, the issuer submitted an application for this issuance and listing to Shanghai in November 2020. Since May 2017, Chengdu Hongtai Yinke will hold Since the issuer’s equity was transferred to Chengdu Fuende Xingyu, the issuer has not changed, that is, no new shareholders have been added in the 12 months before the issuer’s declaration.

After verification, the sponsor and the issuer’s lawyers believe that: the issuer has not added any new shareholders within 12 months before the declaration.

Regarding the abnormal share price, the SSE requires the sponsor and the issuer’s lawyers to verify and explain: (1) The background and reasons for the shareholder’s shareholding, form of shareholding, source of funds, payment method, share price and pricing basis; (2) Historical evolution of the issuer Whether there is an obvious abnormality in the shareholder’s share price; (3) If so, please follow the fourth and fifth provisions of the “Guidelines for the Application of Supervisory Rules-Information Disclosure of Shareholders of Companies Applying for Initial Listings” (hereinafter referred to as the “Guidelines”). The specific circumstances of the thorough inspection; (4) If no, please explain the sufficient reasons and objective basis for determining that the share price is fair.

Kuaike Electronic responded that the background and reasons for the previous shareholder’s share purchases in the history of the issuer are reasonable, and the share price is fair and there is no obvious abnormality.

Regarding R&D expenses and technological innovation attributes, the Shanghai Stock Exchange requires the issuer to explain: the reason and rationality of the issuer’s R&D expenses and the proportion of revenues that are quite different from those of the same industry; the reason for the rapid increase in the number of R&D projects during the reporting period, and the R&D expenses of each project According to the latest audit report, state the issuer’s total R&D investment in 2018-2020 and the proportion of its operating income, and whether the issuer’s indicators still meet the relevant indicators of the “Science Innovation Attribute Evaluation Guidelines (Trial)” Request etc.

Kuaike Electronics responded that during the reporting period, with the continuous innovation of photovoltaic module technology and the application of high-efficiency and high-power panels, in order to ensure the company’s product competitiveness and product performance to meet the needs of module customers, the company needs to maintain product upgrades and forward-looking research Continuous investment has increased R&D investment year by year. During the reporting period, the company’s R&D expense ratio was higher than that of companies in the same industry, mainly due to the following:

(1) The product structure is different. According to publicly disclosed data by companies in the same industry, the main products of companies in the same industry are photovoltaic junction boxes. The company is committed to the research and development and production of bypass protection and connection integrated products. In addition to junction boxes, the main products also include component connection core components photovoltaics Connectors, in order to ensure the safe and stable connection of photovoltaic modules, it is necessary to keep the product performance of the photovoltaic junction box and the connector improved simultaneously, so there are more R&D projects involved and higher R&D investment;

(2) The direction and scope of research and development are broader. In addition to the general-purpose junction box and connector, the company’s research and development focus is earlier involved in the research and development of intelligent junction boxes among domestic companies in the same industry, especially MPPT efficiency optimization and fire shutdown intelligent junction boxes. In addition, the company’s R&D center also actively develops related product research and development, expands the company’s product line, and invests in the research and development of photovoltaic combiner boxes, energy storage connectors, PVT cogeneration and other products, so the research and development expenses are relatively high.

(3) Difference in business scale. In each period of the reporting period, the absolute amount of research and development expenses of Tongling shares was higher than that of the company. The average operating income of Tongling shares and the company from 2018 to 2019 were 792 million yuan and 329 million yuan, respectively. Their revenue scale was significantly higher than that of the company. Its research and development expenses account for a relatively low proportion of revenue.

In each period of the reporting period, the number of R&D projects being implemented by the company are 5, 8, and 14, respectively. The number of R&D projects has increased rapidly, mainly due to the rapid technological upgrading of the photovoltaic industry. The company has continued to increase in order to maintain market competitiveness.

Researchers have gathered tissue samples from patients for brain research after death. Accordingly, the “zombie” gene may influence the study of brain-related diseases if the team prolongs the time to access the sample. The researchers analyzed gene expression from living brain tissue and found that in some cells, gene expression increased after death. They observed that inflamed glial cells develop and grow arm-like branches several hours after death. “Most research confirms that all activity in the brain stops when the heart stops beating, but not really,” said Dr. Jeffrey Loeb, Dean of the Department of Neurology and Rehabilitation at the University of Illinois Medical School. , Chicago. The “zombie” genes are activated after the brain stops working. They are glial genes responsible for attention to damaged brain tissue. Photo: Dr. Jeffrey Loeb / UIC. According to the Yourgenome.com Gene expression is the process of converting genetic information in DNA into functional products such as proteins or other molecules. “It’s not surprising that glial cells develop right after the heart stops beating. These cells become inflamed and their job is to clear things up after brain damage such as hypoxia or a sudden attack. Stroke, “Loeb said in a university press release. Also according to him, the connections are very remarkable. Most research uses post-mortem human brain tissue to find treatments for disorders like Autism, Schizophrenia, and Alzheimer’s disease. However, these studies did not take into account continuation of gene expression or cell activity. “Our findings will shed light on research on brain tissue in humans. It’s just that at this point, we haven’t yet quantified the changes,” said Loeb. Loeb is the director of UI NeuroRepository (at the University of Illinois), a bank that stores brain tissue, with consent, of patients with neurological disorders. Brain tissue is collected and stored when the patient dies or is in surgery. Not all brain tissue is needed to diagnose the disease, some of which is used for research. Loeb and his team noticed that the gene expression patterns in living brain tissue did not match any previous findings of brain tissue gene expression after death. Therefore, they conducted a simulation experiment to observe the expression of all genes in the human body 24 hours after death. As a result, about 80% of the genes maintain relative stability within 24 hours. These include genes that provide basic functions of the cell. Another group of genes, brain activity (such as memory, thinking, and seizure) quickly subsides within hours of death. A third group of genes – the “zombie” gene – became more active while the other groups of genes gradually decreased activity. During the first 12 hours of brain death, activity of the “zombie” gene peaked. “We found 1,427 genes clustered. A cluster of 317 rapidly depleted genes was predicted to be neuron and coincided with genes dependent on activity. The second cluster of 474 genes is predicted to be glia, consisting of astrocytes and microglia. Notably, due to the rapid decrease in the cluster of nerve cells, the glial cell cluster has significantly increased “, the scientists shared. These findings mean that researchers need to take these changes into account and minimize the time from death to study as much as possible to curb those changes that are too big, Dr. Loeb said. “The good news is that we know which genes and cells are stable, are decreasing, and which are increasing over time, which helps guide post-death brain research better,” he said. Therefore, naming the genes that are most active in the brain after death as “zombies” only makes this research more remarkable. This has nothing to do with the zombies in the sci-fi movies. Understanding the brain’s chemical signals is key to helping scientists find ways to cure brain-damaging diseases like Huntington’s chorea. This research was supported by an abundance of resources from the University of Illinois neuroscience archive, a collection of brain tissue samples with epilepsy and other ailments.

1. The composition of different meats will have different amounts of protein. The relative ratio of fat to muscle, the amount of connective tissue and the type of muscle in the meat will determine the ratio of fat and protein inside. Among red meats such as beef, lamb, pig, deer … pork is high in fat and low in protein. This type of meat is usually pale pink to dark pink in color. 2. Modern “super meat” chicken, the most popular breed of chicken today, is the result of careful and continuous breeding of chickens for decades. They are crossed between different breeds of chickens to achieve large size and rapid growth. Today’s industrially-raised chickens are four times larger than those raised 50 years ago, reaching slaughter weights in just 35 days (half as short as traditional breeds). 3. Cows that eat grass have less fat than cows that eat grains, grains about 4% and their fat is usually located just under the skin, rather than in muscle. Although less, grass-fed beef fat contains more essential omega-3 fatty acids, which provide more health benefits than grain-fed cows. 4. Wagyu beef is one of the most searched foods in the world. This type of beef has a lot of fat, making the dish delicious and rich. Raising Wagyu cows has a strict and extremely strict process. Only cows that meet all process requirements are released. So the price per kilogram of premium Wagyu beef can go up to £ 500. 5. Nowadays, many families tend to store food for long periods of time. However, household refrigerators often have low capacity, poor performance far from industrial appliances capable of “super-speed freezing”. Therefore, the maximum freezing time is different depending on the type of meat. It is recommended that chicken pieces can be kept for up to 12 months in the freezer, while beef is for 6 months and bacon or sausage should only be kept for 1 month. 6. Today we often smoke food to create delicious flavors by smoked apple wood or sweet chestnut. When the wood burns, the lignin compounds in the wood decompose and diffuse into a series of aromatic molecules that will float up and stick to the surface of the meat. But lignin only begins to decompose and creates aroma when the wood reaches 170 degrees Celsius. 7. Whether you cut the grain across or along the grain has a significant effect on the softness of the meat, especially the beef. The fiber is understood as the direction of the muscle fibers. When cutting meat to eat, you should cut the grain for the best culinary experience. Sometimes, biting a piece of meat cut along the grain requires a force 10 times more force than biting the meat across the grain. 8. To make a crispy roast successfully, the skin needs to be dried before roasting. Ideally, we should rub the meat thoroughly with salt first and let it sit for a while. The salt will draw the water out. Then blot the surface of the meat dry and place it in the refrigerator to allow it to dry further before roasting. 9. Each type of meat has a different minimum cooking temperature. Chicken, undercooked or under the minimum heat, is dangerous. Chicken often contains harmful bacteria such as Salmonella or Campylobacter. Chicken should therefore be cooked at least 74 degrees Celsius. In addition, pork is recommended to cook at 62 degrees C to destroy harmful bacteria. 10. Salt has many effects in cooking. In addition to flavor enhancement and dehydration in foods, salt is also used to soften certain meats. When marinated long enough, the salt will alter the properties of the protein layer on the surface, making the meat softer. After about 40 minutes of salting, most meats will be noticeably softer.

Odd nature Previously, science only defined the concept of crystals, treating them as solid objects with homogeneous unit cells arranged in a periodic structure. For crystals, a unit cell can only be in the form of a cube, tetrahedron, or octagon. From rock to diamond, all crystals in the universe contain 14 symmetrical structures, each of which consists of a base cell and many atoms arranged in a special way, in which the their position is repeated periodically in three-dimensional space. When the idea of ​​pseudocrystals appeared, people believed that they did not exist in nature, but were only synthesized in a laboratory. Because, certain order of the atoms in pseudocrystals does not repeat the period, giving them innumerable symmetrical structures. Decoding the pseudo-crystal mystery can help science find a solution to the origin of the universe. Science goes crazy about pseudocrystals. Countless theories emerged, some even believed that this strange matter was sent from a distant galaxy inhabited somewhere in the universe. The appearance of pseudocrystals changed everything, ushering in the era of researching a distinct form of solids existence, in which the atoms arranged seemingly regular but without repetition. Experts call pseudocrystalline an “unpredictable unknown” in the universe, breaking the inherent harmony of the world of microscopic atoms. Others say crystal imitation is like a stray note, being “dropped” into sentences deposited between notes in the right rhythm to make a difference. The difference is the non-periodicity of the pseudocrystalline, which lacks translational symmetry. The experiments revealed an interesting fact: when translationally displaced a pseudocrystalline sample, the resulting image does not match the original. This goes against the inherent nature of conventional crystals, characterized by translational symmetry that causes the unit cells to be arranged according to a clear pattern. Because they are not repetitive, the pseudocrystals create many forms of rotational symmetry, which can be observed from many different angles with the same original pattern. For example, Florence pseudocrystalline found in a meteorite falling in the Khatyrka region (Russia) has the form of a 20-sided polyhedron (dichotomy), allowing observations from 60 different angles. Unique minerals The uniqueness of the fragment of a meteorite containing pseudocrystalline Florence lies in the aluminum metal (Al) composition, which raises a big question about the mechanism of pseudocrystalline formation in the universe. Experts also found iron and copper, and compounds of the two metals and aluminum on the meteorite. This is strange because so far, copper does not react with aluminum, unless there is human interaction with certain catalysts, otherwise the “mother of Earth” always separates the two metals. this. The International Mineralogical Association (IMA) has recognized that this dichromatic pseudocrystalline carries a new kind of mineral, with a different chemical composition with the chemical formula Al63Cu24Fe13. In early 2021, experiments at the California Institute of Technology (CIT) investigating three oxygen isotopes confirmed that the pseudo-Florence crystal was most likely from a carbonaceous chondrites meteorite – a material unlike anything on Earth. , formed within hours of the solar system’s birth, is regarded as a space rock, albeit quite pliable. Accordingly, studying this asteroid opens the opportunity to learn about the time of the Sun’s birth. The discovery of many metal isotopes suggesting the formation of the Sun is related to gravitational collapse (the phenomenon of extremely rapid contraction of large masses under gravity), caused by waves. shock from the nearby supernova explosion. Man has always believed that pseudocrystals do not exist in nature because certain order of atoms in pseudocrystals do not repeat the cycle. Yet, science is focusing on decoding strange minerals from space to develop the theory of evolution of the solar nebula, thereby understanding more about the history of the universe. These are pseudo-dichroic crystals with the mineral stishovite (crystallized by dense silica), traces of ringwoodite in meteorites (formed when the olivine mineral is pressed together by extreme pressure and exposed to a medium less pressure), or rare metal compounds such as aluminum-copper and nickel-iron. The most widely supported view believes that metals appear first in the solar nebula, then suffer the “shock” from an extremely strong asteroid impact before “clinging” to the surface of the asteroid. undergoes undetermined reactions to form foreign minerals. Complex structure For the first time, science has admitted finding traces of pseudocrystals in a meteorite, marking a new stage in the race to explain the origin of this matter. The mystery remains, regarding the reason why pseudocrystals appear in nature, and the mechanism by which atoms in pseudocrystals form a complex structure beyond existing theory. From here, two opposing schools were born. The perturbation theory believes that pseudocrystals are made up of atoms in a chaotic state, randomly linked into symmetrical clusters, after which the clusters will flexibly interact with each other, making the pseudocrystalline a zero shape. stability, then gradually decay. On the contrary, Paul Steinhardt, professor of science at Technion University (Israel), proposed the possibility that the atoms in the initial pseudocrystalline attract each other and form clusters with the form of pentagons, hexagons or many “senses”. other. These “senses” are then under the effect of a mysterious force to interact with other “senses” around, forming a certain shape. At that time, the clusters of atoms are bound together, gradually falling into a non-periodic state, creating pseudo-crystal. This connection is scientifically described exactly the property of the Penrose pattern (a famous concept in architecture created by two types of tiles that seal a plane in a non-periodic style). Paul Steinhardt argued that the atoms in pseudocrystals form clusters of many “senses”. While examining Florence’s pseudo-crystalline structure, some evidence confirmed it contained a new pseudo-particle named “phason”, which reverses the atomic clusters, breaking the rules of bonding between them. when one particle interacts with other matter. This finding reinforces confidence in the possibility that crystalline pseudo-crystallinity is completely natural, and emphasizes Paul Steinhardt’s hypothesis as being valid. Besides, science is also very active in learning about the stability properties of pseudocrystals. Two proposed mechanisms, mutually reinforcing in the existence of pseudocrystals, include arbitrary mechanisms and entropy mechanisms (chaotic measurements – the origin for understanding the dynamics of galaxies and the universe). . As the entropy value increases, some of the atoms in the pseudocrystalline vibrate and spin, thereby trying out “spontaneous” bonds, in multiple positions before they are “locked” into a specified position. . Atomic clusters can also overlap, sharing atoms under the influence of arbitrary binding mechanisms. Research on the pseudocrystalline model in the laboratory found that the stability of this material depends on the electron / atom ratio. Therefore, science speculates that the electron possesses the ability to stabilize the atom clusters. However, more evidence is still needed to confirm the stability of pseudocrystals in nature. Obviously, the journey to decode the pseudo-crystal is still very long, with many difficult questions. How, for example, does aluminum, copper and iron coexist inside alloys to form unusual minerals. The presence of aluminum in some meteorite samples raises the question of the metal appearing early in the formation of the solar system. More importantly, whether there exist other types of pseudocrystals in nature, and what kind of forces “lock” the clusters of atoms together. Answering these questions will help science sketch a new picture for the future of physics, while moving closer to the solution to the greatest mystery of all time: this universe ultimately comes from where…

While countries in turn closed their borders, scientists have broken their own borders, creating a global collaboration unlike anything that has happened in history. Never before have so many experts in many countries focused on a single topic and with such urgency, the researchers said. Nearly all other studies have to be halted. Within a few months, all of the global science was almost “COVIDed”. Photo: LG In a survey of 2,500 researchers in the US, Canada and Europe, Kyle Myers from Harvard and his team found that 32% turned their focus to pandemic. Neuroscientists studying olfaction are beginning to understand why patients with COVID-19 tend to lose their sense of smell. Physicists set out to create predictive models that inform policy-makers. Michael DL Johnson at the University of Arizona often studies copper’s toxic effects on bacteria. But knowing that nCoV existed on the copper surface for less time than other materials, he turned to investigating how vulnerable the virus might be to the metal. No disease has been so scrutinized by so many combined intelligence in such a short time. As of February 2021, the PubMed Biomedical Library listed more than 74,000 nCoV-related scientific articles – more than double those of articles on polio, measles, cholera, dengue, or other diseases. another has inflicted on mankind for centuries. Only 9,700 articles related to Ebola have been published since it was discovered in 1976. By September 2020, the prestigious New England Journal of Medicine received 30,000 nCoV-related articles – many 16,000 more than all of 2019. “All that difference is COVID-19,” said Eric Rubin, editor-in-chief of the New England Journal of Medicine. “This is an unprecedented shift in scientific priorities,” said Francis Collins, director of the US National Institutes of Health. In addition, online archives are readily available to provide research data and evidence before periodic scientific journals. Scientists identify and share dozens of viral genome sequences. More than 200 clinical trials have been launched, bringing together hospitals, laboratories and hundreds of thousands of volunteers globally. Speaking in The New York Times, Dr. Francesco Perrone, who leads a clinical trial of nCoV in Italy, said: “I have never heard genuine and excellent scientists talk about nationality. mine, your country. My language, your language. My geographic location, your geographic location. This is really far from true senior scientists. Photo: LG The New York Times revealed that one morning, University of Pittsburgh scientists discovered a weasel after exposure to COVID-19 particles developed a high fever. This is a potential step forward for vaccine testing in animals. Under normal circumstances, they would begin to review the research results with an article in an academic journal. But Professor Paul Duprex, the university’s lead virologist, shared the results with scientists around the world in just two hours, instead of spending months on an article. . A small measure of openness can be found on the servers of medRxiv and bioRxiv, two online archives that share academic data before it is published in journals. The archives are filled with thousands of coronavirus studies around the globe. Chinese researchers have contributed a considerable part to the nCoV research in this treasure. A Chinese lab announced the original virus genome in January, providing the basis for nCoV tests worldwide. Thanks to this initial genetic data, the world’s leading research institutions have based and supplemented the evidence, thereby successfully testing vaccine products with a preventive effect of up to 90% – 95%, in a time of unprecedented speed in history. By November, more than 197,000 nCoV genomes had been sequenced. Lauren Gardner, an engineering professor at Johns Hopkins University who has studied dengue and Zika, knows that the new diseases will come with a scarcity of real-time data. So she and her students created a global online map to count all COVID-19 cases and deaths. After one night’s work, they launched it on January 22. / 2020. Since then, the dashboard has been accessed daily by governments, public health agencies, the media and anxious global citizens. One of the foe-to-friend partnerships mentioned is a joint production cooperation agreement between US pharmaceutical firm J&J’s COVID-19 vaccine and leading rival Merck in March 2021. Emphasizing that the US is in a state of “national emergency” and it is time to act “drastically and boldly”, the two rivals have begun to speed up the production of vaccines, aiming to supply the country. 200 million doses in 2021, bringing America to community immunity. Photo: LG From Asia to Europe, Africa to the Americas, despite the differences in politics, culture, ethnicity, language … scientists share, cooperate, seek all vaccine solutions and remedy against viruses. Even though large, proprietary research may lead to sponsorship, promotion and reputation, scientists have left behind secret ways of working, hoarding data from competitors, to together find the light at the end of the tunnel to save all of humanity. These efforts have paid off. New diagnostic tests can detect the virus within minutes. Huge open datasets on the viral genome and cases of COVID-19 give the most detailed picture of the evolution of a disease that has never appeared in history. Along with the new discoveries revolving around, humankind is prepared with an abundance of scientific resources to be ready for the face of future pandemic. In particular, if no one dared to say anything for sure in March 2020, the positive results of a series of vaccines plus successful antiviral drug antibodies would have brought people to life. closer to the prospect of ending the pandemic. A series of countries launch a campaign to vaccinate hundreds of millions of people by 2021, with the aim of achieving the earliest community immunity, to bring the entire country back to normal as before. Borders will reopen, and laboratories and research facilities around the globe will revive again, and continue to seek solutions that will push humanity toward the future. That is the unchanging mission of science, in any historical moment.

She once defended her Master’s thesis in English with a score of 9.9 and was honored to be one of 31 students and researchers who received a “huge” scholarship awarded by the National University of Ho Chi Minh City.

Passionate about renewable materials

Do Nguyen Hoang Nga graduated from university with an engineering degree in Chemical Engineering at University of Technology – National University of Ho Chi Minh City in 2018 and continued to study for a master’s degree at the school. In 2020, she graduated with a Master’s degree with an average score of 9.63, a thesis in English with a score of 9.9. Hoang Nga is continuing her research work with the Sustainable Process Engineering team led by Assoc.Prof.Dr. Le Thi Kim Phung.

The team’s research direction is to develop technologies to convert agricultural-industrial by-products into renewable materials with high technical value such as aerogels, multi-disciplinary applications such as construction, environmental treatment, food packaging. and aimed at applications in medicine, fuel cells …

MSc Do Nguyen Hoang Nga said that the group is currently focusing on renewable materials from biomass. This field is quite new and is the trend of the current world when the environment is increasingly polluted. Her approach towards zero waste technology, turning worthless things into valuable products has fascinated her for the past two years.

“In 2019, I have access to aerogel synthesis technology from pineapple leaves through the cooperation between the Sustainable Process Engineering team and the Aerogel research team of Assoc.Prof.Dr. Duong Minh Hai – National University of Singapore. After that, my team and I continue to expand this research direction with other types of waste such as fly ash, waste cotton chips, pandan leaf fibers … Up to now, these studies have had positive results at room scale. experiment and pilot, as a basis to be transferred into industrial production when an organization is interested in placing an order “, shared Hoang Nga.

During the implementation of the studies, Hoang Nga and the group encountered many difficulties in funding and analysis equipment. Some of the equipment at the laboratory is not available, so the group has to link with domestic and foreign laboratories to send measurement samples. Passive analysis can sometimes make progress difficult. However, some research topics of the group are supported by funding from scientific funding funds, thus partly removing the group’s obstacles.

Hope to be available on the market soon

With the current research direction on renewable materials from biomass, Hoang Nga and his team wish to create more conditions for research and development of modern and efficient technologies in industrial production.

As an application-oriented research group, the group always puts the feasibility criteria when producing on an industrial scale on top. The direction of non-waste recycling from biomass is approaching in line with the trend of Vietnam as well as in the world when the problem of environmental pollution caused by waste is concerned by many people. After all, the team still wants to apply the developed technology on an industrial scale to the industrial scale of this material to be available on the market early.

Workshop scene.

Prof. Phan Anh reiterated that metaphysical science (Metaphysics) is the scientific field that studies metaphysical phenomena, in which there are many phenomena that appear in social life that people have ever met but did not. It can be explained with the foundations of classical science or traditional science. For example phenomena are related to the existence of consciousness after life (the soul?). Because of inexplicability, people are born with doubts about how real these phenomena are, how their origin governs them, or paranoia, from which trends appear:

1 / Reject and seek to explain by applying science but not enough scientific reasoning and not enough scientific evidence to convince, for example considering the existence of consciousness after life as “residual radiation. “.

2 / Believe but lack certain understanding, do not select information, get caught up in the facts, become superstitious

3 / Research to find out the characteristics and laws governing metaphysical phenomena in order to understand, explain the phenomena and deduce the “messages” behind the phenomena to have a way. behave, do not get caught up in the phenomenon like “superstitious” people.

It can be seen that there is a very thin boundary between Metaphysical Science and Superstition, and it takes great alertness to discern and acknowledge. For many years, a special ability of some people has been observed, including psychic abilities in many forms such as event prediction; receive information from the invisible realm; communicating with the deceased; plays a mediating role in the communication between tangible and intangible … Thus, those with special abilities can bridge the tangible and intangible and can therefore make important contributions to the research. practice some problems of metaphysical science. Some of these problems are:

• Whether or not, the existence of a space other than the tangible space that people are living and perceived by the common senses (invisible world).

• Yes or not, the existence of another conscious form and retains human information after life ceases (soul?)

• The role and influence of cultural and spiritual activities in social life such as worshiping, worshiping and using votive. Do’s and Don’ts.

• The characteristics and laws of the metaphysical world are drawn from the practical observation of phenomena that often occur in social life and the problem of decoding messages …

Professor Dao Vong Duc (former Director of the Institute of Physics, former director of the Center for Human Potential Research) has a speech “Inner nowhere and conveying spiritual interaction through the approach from contemporary physics. great ”. In the speech, there are some notable points. He recalled the history of scientific development that showed that great inventions were obtained not only on pure reason and logic, but also by aesthetic sensitivities and the support of intuition factors. The connotation of “intuition” is to have the Buddhahood “Salvation of Nirvana” in Buddhist terminology.

Studying the micro-subatomic world together with the forms of energy and the laws of interaction in which to create the world around us are the core problems of contemporary physics, in It is of particular importance to build the theory of Grand Unification Theory (GUT), with so far the fundamental interactions are gravitational interactions, electromagnetic interactions, weak interactions and strong interactions. .

He argued that the Grand Unity models based on Quantum Theory and Relativity led to a profound insight into the nature of space-time, the nature of interaction forms and mutual energy forms. application. In particular, there have been ideas about the existence of forms of super interaction with corresponding super energy associated with mysterious supernatural phenomena that the normal human senses as well as modern science and technology. are not qualified enough to detect. The outstanding achievements of modern science and technology originate from the advent of Quantum Theory and Relativity, the greatest achievements of twentieth century Physics. The cross-cutting axiom of Quantum Theory is the Dual Complementary Principle which states that all bodies at once manifest themselves with two seemingly contrasting natures: Waves and Particles. This principle is also completely consistent with the teachings expressed deeply in the Vajra Sutra and the Prajnaparamita Sutta.

He also reiterated the theory of Naturalism that the natural world is a closed system, implying that no external factors can influence that world. However, this is contrary to Gödel’s “Incompleteness Theorem” (1931) which proves that a closed logical system is never non-contradictory, always containing unsolvable propositions. In order to explain everything, there must be more extraneous elements – accepting beliefs, believing in something that cannot be proved. The Incompleteness Theorem proves that science can never fill its own gaps.

Heisenberg, the eminent physicist, who was the first to enlighten Quantum Theory in his Nobel Prize-winning speech, said that, “The first sipping of a cup of water by natural sciences can turn you into nothing. God, but drink more, heaven is waiting for you at the bottom of the cup “…

Senior Lieutenant Colonel Tran Duc Thinh (Deputy Head of Psychology Department) has a speech “Methods of accessing metaphysical information of people with special abilities”. Department of Psychology has spent nearly 25 years of establishment and growth. Through generations of leadership and enthusiasm, talent and foresight; with thousands of pages of documents, hundreds of video tapes – video tapes, hundreds of pictures with the multifaceted metaphysics (death).

According to him, there are a number of methods of accessing information of people with special abilities: Finding the grave through the image, looking at the “death” through the 6-fold chakra, capturing the Thai ancestor’s pulse, by spiritual intuition and the help of the “superior” of the martyrs, communication – contact with the spirits thanks to the help of “superior”, pressure of death, “karma” for treatment. Each method has its own advantages and disadvantages. He said that, evidence on a large scale, persistently following, taking notes, systematically researching the special abilities of human beings – Through many topics of the subject published – as well as conclusions in minutes of the Scientific Conference “Assumption – interpretation of Vong manifestations” of scientists in the speeches (gathered in “Entering the invisible world”). It can be affirmed that: “Vong’s existence is not a matter of controversy” – the issue of spiritism – psychic psychic is real …

There are many high-quality presentations by authors such as: researcher by Vo Lam Thanh, researcher Vo Xuan Tong, Dr. Nguyen Manh Hai, Dr. Nguyen Dang Quang, Dr. Mai Thanh Hai, Dr. Nguyen Hoang Diep … All We also offer points of view of a mysterious and scientifically unprovable world that is metaphysics.

Another family company launched an impact on the A-share market.

Recently, Tangshan Baichuan Intelligent Machine Co., Ltd. (hereinafter referred to as “Baichuan Intelligent”) submitted a prospectus, and plans to be listed on the Science and Technology Innovation Board, with a public offering of no more than 33.4 million shares, accounting for no less than 25% of the total share capital after the issuance.

The IPO Daily found that the equity of Baichuan Intelligent was mainly held by the actual controller, the father and the daughter. The company not only relies on the top five customers for its performance, but is also questioned by the Shanghai Stock Exchange whether it has the attributes of science and technology innovation.

The value of “post-90s”

It is understood that Baichuan Intelligent was established in 1998, funded by Qingyuan Environmental Protection and Liu Jianying.

As of the signing date of the prospectus, Baichuan Zhixin holds 72.09% of the shares of Baichuan Intelligent, Liu Jingyan holds 19.9% ​​of the shares, and Baichuan Zhihui holds 8.01% of the shares.

It needs to be pointed out that Baichuan Zhixin is 100% owned by Liu Jianying, Liu Jianying and Liu Jingyan have a father-daughter relationship.

In other words,Liu Jianying and Liu Jingyan directly and indirectly hold 91.99% of the equity of Baichuan Intelligent and are the actual controllers of Baichuan Intelligent.

In this regard, Baichuan Intelligent said that the company’s operations may be affected due to the relative concentration of the equity structure and the control of the actual controller, and there is a risk of the relative concentration of the equity structure and the actual controller’s control.

In addition, Baichuan Zhihui is the employee stock ownership platform of Baichuan Intelligent.

In other words, Baichuan Intelligent does not have any external shareholders. Relying on its own capabilities, Baichuan Intelligent wants to become a listed company.

In addition, if Baichuan Smart goes public, A-shares will usher in a “post-90s” worth over 100 million yuan.

The prospectus shows that Baichuan Intelligent intends to raise 1.449 billion yuan this time and publicly issue no more than 25% of its shares. Based on this calculation, if Baichuan Intelligent successfully raises funds, its valuation may reach nearly 5.8 billion yuan.

It is reported that Liu Jingyan was born in 1991 and currently does not hold any position in Baichuan Intelligent. After the successful listing of Baichuan Intelligent, Liu Jingyan’s equity ratio in Baichuan Intelligent will be diluted to 14.92%, and the value of the equity held may reach 865 million yuan.

Performance depends on the top five customers
