Speculation about the mysterious origin of the aurora has been around for a long time. But until now, unsubstantiated inferences have been clearly proven. The mystery has been revealed According to a new study published in the journal Nature, a team of physicists from the University of Iowa has finally demonstrated that the aurora is “generated by strong electromagnetic waves during geomagnetic storms.” The Northern Lights appear over a waterfall in Iceland.

Research shows that these phenomena are known as Alfven waves, which launch electrons to Earth, causing the particles to produce a stream of light that scientists call the aurora borealis. “The measurements reveal that the small number of electrons undergo ‘resonant acceleration’ by the electric field of the Alfven wave, similar to a surfer catching a wave and continuing to accelerate while surfing with the wave,” said Deputy Professor Greg Howes, of the Department of Physics and Astronomy at the University of Iowa, is also a co-author of the study, said. The idea that electrons “surf” on an electromagnetic field is a hypothesis first introduced in 1946 by Russian physicist Lev Landau. The theory is named after the physicist who called it Landau damping. After more than 70 years, the Landau damping theory has been proven. Aurora re-creation After decades of research, scientists have understood how the aurora is produced, but only now have they been able to simulate these colorful bands of light. For the first time, artificial auroras have been recreated in the lab using large plasma physics equipment (LPD) at UCLA’s Basic Plasma Science Facility (BaPSF).

According to the CNN , the scientists used a 20-meter-long room to reconstruct the Earth’s magnetic field using powerful magnetic coils on UCLA’s LPD instrument. Inside the room, the scientists created a plasma environment similar to what exists in near-Earth space. “Using a specially designed antenna, we project Alfven waves down the machine, just like when you quickly shake a water hose up and down and watch the waves move along the hose,” Mr Howes said. When they began to experience electrons “surfing” along the wave, they used other specialized instruments to assess how the electrons received energy from the wave. “Although the experiment did not reproduce the range of multicolored light in the sky, our measurements in the laboratory matched predictions from computer simulations and mathematical calculations, demonstrating that the Electrons surfing on Alfven waves can accelerate up to 72 million km / h and create aurora,” Mr Howes said. Study co-author Craig Kletzing added that these experiments allow them to make key measurements to prove the spatial and hypothetical measurements that actually explain how the aurora is produced. The aurora was taken in Alaska. Photo: Getty Images. Many space scientists are also excited by this new news. “I feel so excited! There are very few laboratory experiments that can prove hypotheses and models related to the space environment. Because space is so vast that it can’t be simulated in a lab,” said Patrick Koehn, a scientist in NASA’s Helicopter Physics Division. According to Koehn, understanding the acceleration mechanism of the electrons that produce the aurora will be useful for many future studies. Long road ahead Currently, the theory of how the aurora is generated has been proven, but there is still a long way to go to predict the strength of each upcoming storm. “Predicting the strength of a particular geomagnetic storm, based on observations of the Sun and measurements from spacecraft between the Earth and the Sun, remains a difficult unsolved problem.” Mr Howes said. Howes said they have established the bond of electrons surfing on Alfven waves about more than 16,000 km above the Earth’s surface. And now, they must learn to predict the strength of those Alfven waves using spaceship observatories.

Wax coconut, a famous specialty of Tra Vinh province. Photo: MD. The Board of Evaluation and Acceptance of Scientific and Technological Tasks of Tra Vinh Province has just accepted the topic “Design and manufacture of equipment to determine the percentage of wax in coconuts” by Dr. Nguyen Minh Hoa, Tra Vinh University as the chair. Wax coconut is a famous specialty of Tra Vinh province. However, determining the percentage of wax in coconuts has long depended on the experience of gardeners. The use of Deep Learning classification equipment helps gardeners determine the percentage of wax in coconuts with the correct probability of up to 95%, determine the percentage of solid wax and liquid wax with 80% probability, should be graded by the council. rather. Mr. Luu Van Nhan, Deputy Director of the Department of Industry and Trade of Tra Vinh province, said that in the past to choose wax coconuts, gardeners’ experience was to shake, but often not absolutely accurate. Nhan said, while still working in Cau Ke, a delegation of the National Assembly ordered 50 waxed coconuts, he asked a reputable agent to collect them. But after asking, I found out that there are many fruits like normal dried coconut. Council for acceptance of coconut wax measuring equipment. Photo: Minh Dam. “In such cases, I believe the gardener is not intentional but just mistaken. Therefore, determining the percentage of waxy coconuts is extremely meaningful to avoid the fact that a 150,000 VND waxed coconut turns into a coconut. dry 10,000 VND. I find this research very close to the actual situation and has high practical application significance”, Mr. Nhan emphasized. According to Mr. Nhan, when applying this device, large-scale farmers, businesses that buy raw wax coconuts, and trading facilities will have more favorable conditions in business, especially the There is no doubt between the buyer and the seller. Now Mr. Nhan wants to buy 50 waxed coconuts, just put it in the machine will have results, from that result the price negotiation will be very close to reality. But Mr. Quick said that, to move towards commercialization, the research team’s product should be improved as compactly as possible for easy portability. The meter for measuring the percentage of wax in coconuts works at the acceptance test of the research topic. According to Dr. Nguyen Minh Hoa, Vice Rector of Tra Vinh University, the knowledge economy is developing in line with the trend of industrial revolution 4.0, higher education institutions play a more important role to find new knowledge, transmit spread knowledge and apply that knowledge through scientific research activities and technology transfer into practice. At the same time, schools need to update the latest research from these scientific research results and transfer this technology into teaching to students in order to improve training quality. Because this is a measure for schools in applying knowledge to create practical values ​​for life. At Tra Vinh University, it is clear that 3 basic components including training, scientific research, technology transfer are inseparable, the development trend expands over time to meet the requirements of educational innovation. university education.

Dr. Nguyen Minh Hoa shared: “Over the years, Tra Vinh University has promoted applied research and technology transfer activities among lecturers and students. In particular, focus on strongly developing the invention space among students and lecturers – makerspace, developing student research groups – IEEE Student Chapter at Tra Vinh University, developing Lab – invention space for students students, lecturers, student cooperative models, student farmer associations, and policies to encourage the incubation of start-up ideas, applied scientific research and technology transfer to serve the community. “. In the coming time, Tra Vinh University will continue to prioritize the implementation of projects to deploy research products with commercial potential, focusing on investing in strong research directions, prioritizing community service and closely associated with businesses, departments inside and outside the province in ordering scientific research and technology transfer.

You must have heard a lot about the miraculous effects of planks. 1 minute plank has the same effect as 1000 sit-ups and plank also helps burn excess fat effectively. And then as a magical boost, you plan to exercise to get the body you want. However, practicing constantly is not effective and also does not really understand how to feel muscles. This article will be very detailed about those! Plank not only helps flat stomach The truth is that the plank has a direct effect on the abs because of its high resistance and balance. Not only the abdomen, but all major muscle groups around the abdomen including transverse abs, longitudinal abs, external obliques, and glutes are involved. You will feel your stomach heat up day by day. That is the process of burning the excess fat that covers each muscle bundle. This increases firmness and helps create better body curves. The anatomical picture clearly depicts the muscle groups involved in the plank. The reason why you only hold 1 movement at a time but are very tired is that. The structure of human abdominal muscle groups is divided into 4 main groups and all 4 are affected and developed by just one plank movement. How does Plank help you in creating abs? It’s not just base 11 but much more. Transverse abs (diaphragm): Helps you to lift heavier weights. Straight abs: These muscle groups will increase athletic performance. In particular, this abs helps women to have a flat, toned stomach. For men, it helps to build 6-pack abs. – Oblique abdominal muscles (intercostals): Increases the ability to fold better. – Butt muscles: Muscles create the description of “peach butt” as women have always dreamed of. How long is the plank effective? Plank is an exercise with extremely simple movements, you just need to practice the correct posture and stay in that position for as long as you can tolerate. Is practicing plank as long as possible as rumored? This is one of the misconceptions that many people encounter. According to research by Spine Professor Stuart McGill of the University of Waterloo in Ontario, Canada, practicing Plank for a long time will have no effect except to help you break world records. In addition, practicing Plank for a long time also has the risk of causing unnecessary injuries to the body and reducing training performance due to loss of strength and wrong form. Research by Professor Stuart McGill was carried out on 168 students of the sports school and the results showed that the average plank time for men is 1 minute 47 seconds, for women is 1 minute 30 seconds. In addition, the professor also gave the results after a month and a half of research that the group who performed short plank exercises had better muscle contraction and endurance than the group that performed consecutive planks. According to consultant of Promix Nutrition and Mr. Albert Matheny, founder of the SoHo Strength Lab fitness center, the effective plank hold time is at least 10 seconds. PhilanthroFIT founder and famous personal trainer in the US, Mr. Doug Sklar said: “Each person should try to do at least 3 sets of plank, each set is at least 60 seconds.” Conclude: The plank training is effective when you hold the plank position for at least 10 seconds and the optimal time to do the plank is about 2 minutes. Tips for newbies to plank You should not be too confused, but you should also be alert enough to measure your strength and find a sample video to practice with. For those who have not exercised regularly, it is difficult to plank for 1 minute. Therefore, you should divide into short breaks, to ensure you have the correct technique and, importantly, feel the muscles described above. You should not be eager to exercise for a long time when your abs are not strong. When the abs are not strong but you want to try to maintain the plank for longer, it is easy to lead to the wrong plank movement, the back plank causes the spine and back to bear the load. This can damage the spine and cause back pain. When you lose strength, you will easily stumble upon these mistakes that lead to injury. If you have just started practicing and can not hold the plank position for long, you can divide the plank into several small sets, each set you try to hold the correct position for at least 10 seconds then rest for 5-6 seconds and then Repeat the movement about 5-6 times, which means that each time you practice at least you can do more than 60 seconds. Once you get used to it, you can gradually increase the plank time. Note “blood and bones” when planning Plank requires a great deal of force, so to avoid muscle cramps or stiffness, you need to warm up and stretch before and after exercise. Regardless of any exercise, it requires a certain amount of perseverance, the abs will not go up or the fat will not go down in just day 1, 2, but need to be done regularly and regularly. To perform an effective plank, you must also combine it with a healthy balanced diet. Don’t fast or starve and don’t overeat, just eat enough. Summer is coming again, high temperatures will make you sweat more, so it will be essential to drink enough water. Reasonable water index is 40ml/1kg body.

Researchers wear protective gear at the Wuhan Institute of Virology. Photo: Xinhua US President Joe Biden announced last week that the US intelligence community had questioned two possible origins of the COVID-19 pandemic: “Human contact with infected animals or a laboratory incident. “. He ordered a new investigation “to bring us closer to a final conclusion”. According to Bloomberg, no matter where the investigation leads, the history of laboratory safety shows that leakage of pathogens has happened, sometimes with deadly consequences. Smallpox virus leak By the late 1970s, smallpox had been eradicated from the wild, but research on the disease continues in several laboratories around the world, including one in Birmingham (UK). where a virulent strain of smallpox virus is handled. In the summer of 1978, a medical photographer working there named Janet Parker became ill. When pustules spread on her body, the local doctor diagnosed it as a severe case of smallpox. Victim Janet Parker in the smallpox virus leak from the laboratory. It was the third leak of the smallpox virus in that decade from a UK laboratory. The British government has drastically stopped the outbreak by urgently isolating hundreds of people and vaccinating many others. Thanks to those efforts, only one other person became infected, and that was Parker’s mother. However, the female photographer experienced a painful, lonely death in quarantine, and is believed to be the last known fatal victim of smallpox. But there are other victims of the incident. At that time the press mentioned the director of the laboratory in Birmingham, a smallpox virus expert named Henry Bedson. Although there was no evidence, the media still blamed him for the incident. Quarantined at home and in despair, Bedson slit his own throat and died shortly thereafter. The British government has organized a thorough investigation into the outbreak. An investigation found Mr Bedson may not have followed adequate safety procedures and speculated that Parker contracted smallpox from a virus that leaked into the gas pipeline. Technicians at a laboratory in Rockville, Maryland (USA), where smallpox vaccine is produced. A lawsuit later dismissed this explanation, and raised the disturbing possibility that Parker herself had entered one of the workspaces without proper protection. To this day, the debate over the Parker incident remains unresolved. Anthrax spores from the lab When laboratories let pathogens leak in a secret environment, it is much harder to confirm the source of the outbreak. A case in point is the anthrax outbreak in Sverdlovsk, a rather isolated city in the former Soviet Union. In 1979, rumors of anthrax killing dozens, even thousands, began to spread to the West. Later that year, Soviet newspapers confirmed some reports, noting that more than 100 people had contracted anthrax after eating contaminated meat, and over 60 had died. It was a tragedy, but perhaps unavoidable because anthrax is readily apparent in local animal populations. However, US intelligence officials are not convinced by that. Satellite images show disinfecting truck-like objects around the city, with a significant focus of activity on a mysterious military facility known as Complex 19. CIA analysts have reported hypothesized that the Soviet Union leaked a weaponized form of anthrax. The Soviets reacted indignantly to this allegation. In 1980, Russia’s official news agency Itar Tass published a rebuttal titled “A Seed of Deception,” accusing the US of making false statements to gain geopolitical advantage. Sverdlovsk was once one of the military secret cities of the Soviet era. Then, under the administration of President Ronald Reagan, the CIA sought to better handle what happened. They asked Matthew Meselson, a distinguished geneticist at Harvard who worked on the bioweapons ban program, to directly assess the evidence. Mr. Meselson was not convinced by the US intelligence findings. In the 1980s, he rejected another theory that the Soviet Union used some kind of fungal weapon in Laos – and he initially held the same view on the anthrax case, endorsing the main explanation. information from the Soviet Union, with one important caveat: Without a thorough investigation in Sverdlovsk, it would be impossible to know for certain what happened. Essentially, Mr. Meselson supported the explanation that the meat was tainted, judging it to be “completely reasonable and consistent” based on what was known about anthrax. He also arranged meetings with Soviet scientists to add credence to this interpretation, with slides of pathology samples taken from the victims. The US intelligence community, however, remains skeptical. And in this case, the intelligence agencies, not the scientists, turned out to be right. After the breakup of the Soviet Union, Meselson and other researchers finally had access to pathological samples taken from the victims’ lungs, which showed they had died from inhaling anthrax spores. Subsequent revelations added to the picture of what happened. Turns out Complex 19 is a biological weapons facility. Here they produce anthrax spores. According to the Laboratory Director of Complex 19 at the time, a filter connected to the spore dryer was clogged. This still happens often. The military officer in charge left a message for his replacement on the next shift but did not enter the logbook as is customary. When it came to the next shift, the replacement team looked at the notebook, saw nothing, and restarted the purifier. A series of anthrax spores quickly spread throughout the vicinity. Mr. Meselson eventually pieced together all the data and published a paper in the journal Science, which combined wind data with interviews, pathological samples and other evidence to describe the outbreak. Coal killed more than 60 people. That was in 1994, 15 years after the incident. Mysterious flu virus leak In addition, there is another incident that took place in the Soviet Union that is still a mystery. In the same decade that witnessed the leaks of smallpox in Britain and anthrax in the Soviet Union, there was also an unusual strain of flu at the time, called H1N1. Laboratory virus leaks have had deadly consequences. Photo: Atlantis In 1977, an H1N1 outbreak broke out on the border between China and the Soviet Union. The epidemic eventually spread worldwide that year, causing an unusual proportion of young patients. The mortality rate from epidemics is relatively low compared to some strains of influenza. But that’s not the problem. The worrying aspect of the epidemic is that this particular strain of H1N1 has not been present since 1950, when it was superseded by other strains of influenza. The appearance of that kind of “back in time” was confusing. Some researchers speculate that the virus may have “escaped” from a laboratory in the Soviet Union or China, but both countries deny this theory. However, the matter remains a puzzle for virologists. Many theories have been born and come to explain the so-called “frozen evolution”, among which the most prominent is the hypothesis that the virus spread to humans from a laboratory, possibly testing a vaccine to neutralize the disease. swine flu. A scientist involved in the development of a vaccine. Photo: Reuters The exact origin of COVID-19 may not be known All of the above incidents occurred in the 1970s. Laboratory safety was expected to have improved since then, but that has not always been the case. After the SARS outbreak in 2003, laboratories around the world began studying the virus. Since that time, there have been no less than 6 laboratory leaks of SARS. The first occurred at the National University of Singapore, where a student contracted the virus from a sample of the virus. This was followed by an incident in Taiwan/China, where a researcher contracted the virus, possibly during the disinfection of waste products from the laboratory. After that, several leaks happened at the National Institute of Virology of China. In one incident, a researcher infected her mother with the virus, and she died of SARS. In all cases, human negligence, mainly exacerbated by inadequate safety protocols, was the cause of the pathogen leakage. History has supported the theories being put forward that the current COVID-19 pandemic may not have a natural origin, but we are not in a position to rush into judgment. When it comes to lab leaks, the investigation and review process often takes a long time, and sometimes the answers remain unsatisfactory and incomplete. In the case of the COVID pandemic, we must prepare for the possibility that the world may never know the exact origins of a pandemic that has claimed millions of lives.

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.”

Before the Lab was officially launched on May 27, PTIT’s technology experts collaborated with Naver Labs Europe’s team leaders to carry out the first research projects. It is expected that these studies will make a significant contribution to the digitalization process in Vietnam, and at the same time contribute to turning the country of more than 96 million people into a global player in artificial intelligence in the early next decade. . Academy Director – Mr. Vu Van San said: The corporation’s “global AI research and development belt”, along with ongoing research activities at PTIT, the cooperation and sharing of core AI values ​​from Naver will play a significant part in the building the Academy’s “miniature digital nation” and jointly developing and creating high-tech “make in Vietnam””. The main activities of the International Research Department on Artificial Intelligence and Multimedia Data include: Organizing courses for students including training in Embedded, IoT, AI, Big Data, Blockchain, Data; Organize student and faculty exchange programs. Vietnamese students and lecturers will have the opportunity to participate in exchange activities arranged by Naver; Transfer and apply Naver’s strong technologies, products and services; Developing new curricula and international training programs; Grant scholarships to outstanding students in the AI ​​field of PTIT; Conducted a joint research project between Naver and PTIT.

The large-capacity “field” Covid-19 laboratory at the Bac Giang Center for Disease Control has been fully installed with the cooperation and transfer support of the Military Medical Academy (Hanoi). This area has an area of ​​​​about 200 m2 and was built quickly in 3 days. The center consists of 8 specialized rooms. In which, 2 laboratories meet biosafety level 2. The most dangerous room is the initial sample processing room. This is the workplace of many officers from the Military Medical Academy, Bac Giang Center for Disease Control and volunteer technicians. Responsible for operating the laboratory is Lieutenant Colonel, Dr. BS Ho Huu Tho (Head of Department of Gene Technology and Cell Genetics, Military Medical Academy). According to Dr. Tho, the special feature of this laboratory is that the SARS-CoV-2 virus detection process is highly sensitive, with the cost savings being reduced by nearly half compared to traditional methods. At the same time, the center has the capacity to test tens of thousands of people every day. According to Dr. Tho, this is the world’s first gene technology, using artificial intelligence to analyze PCR results to detect SARS-CoV-2 pathogens (known as AIMS RT-PCR technology). The sensitivity of this method was evaluated against an in vitro RNA standard set for a detection threshold of 7.2 copies/reaction, nearly 7 times lower than the WHO recommended procedure, when evaluating under the same experimental conditions (50 copies/reaction). This study was clinically evaluated on 142 positive cases, 1,034 negative cases for SARS-CoV-2 and 14 other respiratory viruses. The sensitivity and specificity of the method were both 100%. More importantly, the procedure was successful in mixing 100 patient samples in a single real-time reaction without compromising sensitivity. As such, this is a simple, super-sensitive and potential test method for large-scale screening of SARS-CoV-2 with cost savings many times over. According to Dr. Tho, this method is like a weapon we switch from a defensive state to an attack against the Covid-19 epidemic. To communicate with the staff working in the lab, the commander had to use a walkie-talkie system because the windows were always foggy because of the mist and Chloramin B disinfectant. Besides, the technician was wearing clothes For protection, entering the lab will be called by the number corresponding to the job they are undertaking. After each opening to receive samples, the room is sprayed with disinfectant to avoid the risk of infection. All generated waste is also collected and treated according to regulations of the Ministry of Health. To maintain testing capacity, nearly 100 cadets of the Military Medical Academy are divided into small teams working for 8 hours, with 3 rotating teams each day to ensure that the laboratory is always open 24 hours a day. Tran Hoang Minh (student of Military Medical Academy) and friends relax before the shift. He is in charge of the work of separating and taking samples, so the risk of infection is very high. However, Minh feels proud to work at this center. “The laboratory capable of large-scale testing is a very powerful weapon in the fight against the epidemic. With mobilized human strength, strong weapons and high determination, I believe the epidemic will be quickly controlled.” male students share.

A heart cell organ that can beat like a real heart. Photo: livescience According to sciencemag.org, this mini organ (cell organelle) mimics the real heart of a 25-day-old human embryo and could help solve many mysteries, such as why children’s hearts don’t have scars. after having a heart attack. Not involved in the new study, but Zhen Ma, a cardiac organelle development bioengineer at Syracuse University, says it’s a great study, and the experiment is important in understanding Congenital heart defects and human heart formation. This process has so far relied solely on animal models. Although other mini-organs such as the brain, intestines, and liver have been grown in the lab for more than a decade, the heart cell organ presents a more challenging challenge for scientists.
The first cardiac organoids were created from mouse heart cells. They may beat on a lab plate, but they look like a bunch of heart cells, not a real heart. According to Aitor Aguirre, a stem cell biologist at Michigan State University, the cardiac organelle needs to function. With the heart, one wants the heart cell organ to have chambers and function to beat in rhythm. Watch a video of a mini heart beating in the lab (source: Sciencemag.org): To create an embryonic-like self-organizing heart cell organelle, the authors of the new study programmed human pluripotent stem cells (cells that have the ability to develop into any type of tissue). which) for this cell to turn into other types of heart cells. They wanted to create three layers of cells in the wall of the chambers of the heart, one of the first developing parts of the heart. Next, they embedded these stem cells in different concentrations of growth-promoting nutrients. They tried until they found a recipe to get these stem cells to form tissue in the correct order and shape in the embryo. After a week of development, the cardiac organelle was structurally equivalent to the heart of a 25-day-old embryo. At this stage, the heart has only one chamber, which will later be the left ventricle of the mature heart. Cardiac organelles are only about 2mm in diameter and have the typical major cell types in this stage of development: myocytes, epithelial cells, fibroblasts, and the epicardium. They also have a clear chamber that beats at a rate of 60-100 beats per minute, similar to the heart rate of embryos of the same age. Lead study author Sasha Mendjan, a stem cell biologist at the Institute of Molecular Biotechnology of the Austrian Academy of Sciences, said: “When I first saw it, I was surprised that these chambers had self-forming. What’s amazing is that you see right away whether this experiment works and if this organelle is working, because it has a pulse.” Scientists were able to study heart formation in unprecedented detail. Photo: livescience The mini-heart has so far been more than three months old in the lab and will help scientists monitor the heart’s development in unprecedented detail. They can know the source of heart diseases such as congenital heart defects in children and heart cell death after a heart attack. Mendjan and his colleagues also frozen organelles to test their response to injury. They found that cardiac fibroblasts, a type of cell responsible for maintaining tissue structure, travel to the site of damage to repair dead cells, as happens in children who have had heart attacks. Scientists have long wondered why children’s hearts can regenerate after being damaged without scarring, unlike adults. Mr. Aguirre said the next step would be to connect this organ of beating heart cells to a network of blood vessels and test its ability to pump blood. Mendjan’s team intends to find a way to modify the nutrient solution to produce a four-chambered heart cell organ. With this innovative heart cell organ, researchers were able to learn more about heart problems that can arise when the walls of the heart’s chambers begin to form. Meanwhile, Mr. Ma said that growing a more mature heart cell organ with all four chambers and structure is a matter of the future. He thinks this will take a decade to materialize.

Up to now, VHT has registered a total of 276 industrial property applications, of which in 2020 it completed research on 48 core technologies applied to products, registered and accepted 66 patent applications. VHT has been granted 4 new international patents by the US Patent and Trademark Administration (USPTO). VHT is also granted 19 domestic patents, 5 utility solutions and 7 exclusive designs. Along with that, VHT has 25 articles published and presented at prestigious national and international journals and scientific conferences. According to VHT Deputy General Director Nguyen Cuong Hoang, the protection of intellectual property by registering national and international patents is an important basis for VHT to be the owner of core technology, ready for integration. It has full competitiveness with international corporations, affirming Viettel’s leading position in the field of research and development of “Make in Vietnam” products. 4 VHT’s patents are protected exclusively in the US: 1. “Random data division in multiprocessor distributed systems” – OCS Research Center. 2. “Method of detecting water surface targets in noisy environment, application in coastal radar station” – Radar Center. 3. “Invention of power steering mechanism for parallel robot by spring system with constant power assist” – Center for Simulation Modeling. 4. “Method of adjusting and controlling the power of the receiving link adapting to the transmission environment in the base station system” – Broadband Radio Equipment Research Center. Mr. Nguyen Cuong Hoang said that in order to achieve success in the past period, VHT always closely follows the viewpoint in the field of research and development in the word “VTOPIC”. Specifically: V – Virtual, using simulation tools to support the research process; T – Technology, VHT determined to follow the field of research and development from core technology, latest technology (latest technology); O – Open, VHT determines the spirit of openness internally and externally, willingness to cooperate internationally, transfer technology on the basis of its own ownership; P – People, VHT holds talented engineers, in the team there are more than 30% doctors, masters from abroad, there are leading international experts from the US, Singapore, Taiwan…; C – Challenge, setting high goals and challenging is the guiding principle for development; I – Infrastructure, VHT has the most modern lab system in Vietnam and can be said to be not inferior to any country in Southeast Asia.

Broadband Radio Center Answering the question of why VHT can achieve many high-tech research and development achievements, especially the successful registration of 4 exclusive patents in the US, Mr. Nguyen Cuong Hoang said, the important issue especially their capacity and technology; Internal strength is decisive. All the results have been accumulated over 10 years of VHT. Currently, VHT has world-class products in many fields such as military, information machines, radar equipment, etc., which can completely compete with the world’s leading corporations. “If I can compete in terms of technology, there are certainly a lot of core technologies and algorithms that I can bring to register for intellectual property. Which markets do I target, I will start to register for protection in that market. The first milestone to conquer is the US, if it is already in the US, it will be much simpler in other markets because the US is the most difficult market”, said Mr. Nguyen Cuong Hoang. The VOTO driving simulation cabin system is researched and developed by VHT In the world today, the US is considered one of the countries with the most patents. Patents granted by USPTO will have to go through many of the world’s most rigorous censorship and evaluation processes. Therefore, getting a patent from this agency is an extremely difficult process. Mr. Phan Thanh Hai, Director of the Appraisal Center, Intellectual Property Department (Ministry of Science and Technology) said: In the last 5 years, the number of Viettel’s patent applications has grown continuously. The fact that Viettel has 4 US-patented patents has great significance in affirming the technological capacity and development orientation of Vietnamese enterprises. Nguyen Vu Ha, General Director of VHT affirmed: “The US patent is a recognition of inventions and scientific research, thereby, affirming that Vietnamese people can compete with corporations. major technologies such as Huawei, LG, Nokia… Intellectual property rights are affirming an indispensable role in the process of forming a comprehensive economy and sustainable development. The certificate of intellectual property rights is the evidence to ensure the success of each enterprise entering the world arena.
