Many people know that China’s coastline is very long and has many island resources. In addition to some large-scale and tourism-influenced islands, there are also many other aspects of the distribution of island resources, and this can also show that its island resources are very prominent. In the world, many countries also have abundant island resources. Some islands have different shapes, distinctive features, rich cultural connotations and rich landscapes. The resulting culture is very rich, which also promotes the development of their islands. Will become bigger, and this part of the resources can also be seen to a certain extent that the island resources are very representative, and the cultural charm generated by this is relatively large. The editor will introduce a few See the island resources, especially some animal resources inside the island.

Colon Islands

This island is located off Ecuador in the eastern part of the Central Pacific Ocean. It is composed of 13 small islands and 19 rocks. It has a large area and a long history. The reason for its formation is also very simple. It gradually formed after a long time of accumulation. Nowadays, this island is called the “living museum of biological evolution”. This is mainly due to its unique climatic environment and geomorphic characteristics, which have prompted many creatures to settle here, and over time, it has formed a very important place in the world. Rare cultural atmosphere, so when developing its island tourism, its cultural charm is even greater.

Animal resources

The most worthwhile animal is the penguin. Many tourists will be confused. Penguins should live in the South Pole in the southern hemisphere. Why do penguins live in the northern hemisphere? In fact, this is also the power of nature. Because this is the only island in the northern hemisphere where penguins live, and there are many reasons. One of them is that it is affected by the Peruvian cold current, which makes it not a high-temperature and rainy natural environment, but suitable The penguin survived.

In addition to penguins, there are also many other types of islands in this island, such as sea lions and seals. Of course, it also contains some special species. So over time, it has formed a very unique cultural charm, which also promotes this island. The ecological environment of the city has become better. Because it is less disturbed by the outside world, many natural environments have been better preserved, which also makes tourists feel very appreciative.

Editor’s View

The island resources in the world are very rich. No matter which island resource it is, tourists need to focus on protection, strengthen and enhance the awareness of protection. Only through protection, the development of its islands can be protected to the greatest extent. Therefore, after the performance of its island development in the future, it will also be loved by many tourists. The development of tourism also needs to strengthen the protection of its islands.

The project “Research and production of biochips based on DNA microarray technology for the diagnosis of some human diseases”, belongs to the Program to develop a number of high-tech industries managed by the Ministry of Industry and Trade. The goal of the project is to master the technology of manufacturing biochips based on DNA microarray; to produce biological chip sets that meet the quality standards of in vitro diagnostic biological products – IVD; At the same time, these biochips can be applied to clinical diagnosis. BIMEDTECH officials and employees implement the project To implement the project, BIMEDTECH collaborated with leading units such as the National Institute of Hematology and Blood Transfusion, the Central Lung Hospital and the Cardiology Institute – Bach Mai Hospital to conduct surveys of known gene mutations. found in biochips of international production and a number of new or specific genetic mutations in humans and pathogens in Vietnam that are associated with diseases: thalassemia, 17 bacterial strains non-tuberculosis (NTM) and clopidogrel-resistant patients in patients undergoing cardiovascular intervention. Along with that, BIMEDTECH has invested in building a clean room system and the world’s leading advanced and modern equipment and machines into the factory in the Hi-Tech Park of Ho Chi Minh City. BIMEDTECH has signed cooperation agreements with high-tech companies in the United States and Europe to receive technology transfer for the production of DNA and Protein Microarray, the foundation for developing products for the diagnosis of a number of diseases in Vietnam. people. Take the lead in mastering technology With the support of the program, BIMEDTECH team has developed 3 products: BIMEDCHIP Thalassemia Detection Kit for diagnosis and treatment of thalassemia. This is the first in vitro diagnostic kit product made in Vietnam that allows simultaneous detection of many mutations causing congenital anemia including alpha and beta – thalassemia in just one test with accurate results. , fast time to get results with suitable cost. Thalassemia is a group of inherited anemias. Vietnam is a country with a high prevalence of thalassemia in the world: About 3% of the population carries the thalassemia gene, the prevalence is about 0.5-1% for the Kinh ethnic group, and a high increase of 10-25% in the Kinh population. some hill tribes. Early diagnosis and treatment of thalassemia reduces morbidity and mortality from thalassemia. Next, is BIMEDCHIP Non-tuberculous Mycobacteria Panel Kit for TB diagnosis. This kit provides results quickly, in as little as 6 hours, compared to traditional culture methods that can take weeks. Providing fast and accurate results helps medical staff to provide effective and timely treatment regimens, bringing benefits to patients. In particular, BIMEDCHIP Cardiovascular Drug PGx Testing Kit allows to detect whether a patient has changes in genes related to liver metabolism of Clopidogrel, Statin, Sinthrome drugs or not in a single test, thereby helping medical staff choose the right dose or drug for each patient, bringing the best effect for drug use. The successful implementation of the project is expected to contribute to improving the current limited production of medical equipment in Vietnam, meeting the increasing health care needs of the community, and at the same time. making an important contribution to the successful implementation of the Program on the development of a number of high-tech industries.

– Currently, ASF has reappeared in a number of small livestock establishments in the province. From 5-5 to 11-6, the disease occurred in 11 households, 7 villages and groups of communes and wards: Suoi Tan (Cam Lam district), Cam Phuoc Dong (Cam Ranh city), Phuoc Dong, Vinh Hai (Nha Trang City). The number of dead and diseased pigs forced to destroy 236 pigs with a weight of 10,463kg. It is expected that the disease tends to arise and spread quickly in the near future. – To control ASF, from now until the end of the year, what solutions will the industry have, sir? – ASF is a contagious disease, so proactive monitoring, early detection, warning, timely and effective application of epidemic prevention and control measures is the most important solution. Along with that, the process of analyzing the epidemiological situation shows that pig farms and facilities with good biosecurity and veterinary hygiene conditions will minimize the possibility of infectious diseases. Therefore, the ASF prevention and control plan in 2021 sets out the goal of successfully building at least 4 disease-free pig breeding facilities, meeting the supply of breeders for breeders. The plan also sets a target that 90% of large-scale farm breeding establishments, 50% of medium-sized farm breeding establishments and 30% of small-scale farm breeding establishments will apply pig husbandry measures. biological safety. – To achieve the above goal, what are the requirements and tasks of the plan, sir? – For biosafety pig production, farmers shall declare, update and declare livestock activities with local authorities; strict application of biosecurity measures and good husbandry practices. At the same time, the use of animal feed must have a clear origin and meet the prescribed standards; Limit the use of leftovers and recycled food from restaurants, hotels, and industrial parks. The organization of rearing the herd applies only to pig production facilities that have not been affected by ASF or where the disease is present but 21 days have passed. For localities that have not announced all ASF, they can only be raised at concentrated establishments that have been certified for disease safety, biosecurity or certified by local authorities and veterinary agencies to meet all requirements. disease safety requirements to re-herd and increase herd. Together with breeders, local authorities and veterinary agencies will closely monitor the disease, promptly detect and handle outbreaks as soon as they arise, to avoid spreading. In particular, the timely and proactive declaration of farmers when the pig herd shows signs of disease and the proactive monitoring of the veterinary agency will be implemented in parallel. The plan has specifically calculated the process of culling pigs infected or suspected of being infected; the control of transportation and trade of pigs and pig products; management of pig slaughter and the consumption of pork products; cleaning, decontamination and disinfection of the livestock environment when there is no epidemic and at the points where the epidemic occurs… – Can you tell me the financial mechanism to implement this plan? – According to current regulations, for pig raising establishments, cooperative groups and cooperatives, the State will partially support, farmers partly; and livestock production enterprises and households in joint ventures and production linkages with enterprises in the province to self-finance funds to organize the implementation of ASF prevention and control measures. In 2021, the provincial budget to implement the ASF prevention plan is nearly 3 billion VND, the district budget is more than 1.1 billion VND. Funding from the state budget is mainly used to purchase and organize spraying of chemicals to clean and disinfect the breeding environment; sampling surveillance, ASF diagnosis; propaganda and training on ASF prevention and control… – Thank you Sir!

The 5-hectare burdock field in Mac Binh village, Thai Tan commune is invested by Mr. Nguyen Manh Ha, Director of Senfarm Agricultural Cooperative, in association with households in the village, setting up a tree farm. on alluvial land along the Thai Binh river. According to Mr. Ha, burdock is a relatively easy plant, taking care of burdock is only difficult in the first one to 1.5 months because it has to be watered regularly, then the plant grows on its own, almost without care. fertilizer, only waiting to harvest when the plant has matured. Harvesting burdock is also different. Because burdock roots are deep in the ground, with tubers up to 1.2 m long, an excavator must be used. After six months of planting, burdock is only harvested, but the economic efficiency is two to three times higher than that of carrot, which is a traditional local crop. Fresh burdock root is supplied to high-class agricultural stores in Hanoi and food manufacturers at prices ranging from 90,000 to 120,000 VND/kg. Burdock can be grown all year round, which is quite convenient in crop rotation. It should be noted that the soil suitable for burdock is loose soil, preferably alluvial soil in the riverside area. Here, the root system develops well, provides enough nutrients, the tree will grow well, has high resistance to pests and diseases. In addition, the tree does not tolerate waterlogging, so the soil must be able to drain well. Burdock seeds need to be purchased from a reputable establishment that has the ability to grow quickly and has good resistance to pests and diseases. From the successful trial planting, Mr. Nguyen Manh Ha has guided people in the commune to plant and buy burdock root to help them, forming a chain of production and consumption links. Accordingly, some households have switched from growing carrots to burdock. In addition to planting and producing burdock, Senfram Agricultural Cooperative also cooperates with processing factories to market products such as fresh burdock, sliced ​​dried burdock, burdock cake, and other products. fermented burdock products, burdock tea bags…

Dr. David Muller with the high-density biopatch. Photo: Hung Vu. The technology allows researchers to use a bio-patch containing a dry layer of vaccine and then apply pressure from the injection device to deliver the vaccine into cells below the surface of the skin. Besides not using needles, this technology being tested on mice also has the outstanding advantage that it does not need to be stored in the cold chain. According to Dr David Muller, Australia’s leading virologist who was involved in the development of the new injection method, the Covid-19 vaccine delivered via a high-density biopatch induces a better immune response and faster. This technology has also shown to be more effective against dangerous variants of the current SARS-CoV-2 virus. What is unique about this single-dose vaccine technology, says Dr. Muller, is that it can help accelerate global vaccine coverage efforts, especially in low-income countries and regions of the world. remote areas. Tests to date have shown that when coated on a dry patch, the vaccine remains stable for at least 30 days in an environment of 25 degrees Celsius and 1 week if it is at 40 degrees Celsius. Using this technology, vaccines will not need to be preserved in complicated and expensive cold chains like today. The developers believe that the applicability of the new technology is very promising. In addition, scientists are also looking for funding to be able to conduct clinical trials on humans in the near future.

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.

Eel farming according to new model. (Photo: Anh Tuyet/VNA) Farmers in Can Tho city are very excited because intensive farming of field eels using water circulation technology has helped them stabilize their livelihoods and get rich with typical products. This is a research achievement that has been implemented into reality by scientists of the Can Tho University . Associate Professor, Dr. Pham Thanh Liem, Head of the Department of Freshwater Aquaculture Technology, Can Tho University, Head of the project, shared from the fact that eel farming households in Can Tho are implementing two projects. farming, with soil and without soil with plant media or bamboo/nylon blisters all have limitations. Because, for the farming model with land, the stocking stock is large in size, often using natural seed, the food used is trash fish or homemade food, low density, eels hiding in the mud become a hindrance in the management of feed and health of farmed eels. In landless farming model , if it is an eel obtained from the wild, the growth and yield are lower than the land culture model. The rate of water change in both farming methods ranges from 1-1.3 times/day with 100% fresh water. Both of the above methods give low eel farming productivity of less than 10kg/m2. If the stocking density is increased, the water exchange rate will increase and increase the risk of disease, environmental pollution and food safety. Since 2018, the research team has implemented the intensive farming model field eels by water circulation technology. This is a model that meets food safety and traceability requirements, while maintaining environmental quality and protecting natural resources. The strength of the model is the application of technical and biological solutions, self-cleaning and reuse of water sources, increasing the maximum eel farming density up to 600 fish/m2 and increasing productivity to 25kg. commercial eel/m2. The productivity of farmed eel also increased from 2.5-4 times compared with conventional farming model; profit efficiency is from 36.5-60.2%. Households raising eel under the new model ensure safe operation, control of pathogens, health and quality of farmed eel products; minimize the rate of water change, increase the output of cultured eel; improve and increase the growth rate, eel quality and production efficiency; allows the treatment of contaminated water and helps control the discharge process. Thereby, contributing to environmental protection; forming and developing farming technology to create clean, high-quality products, meeting the needs of consumers. Currently, the model is starting to be transferred and deployed in a number of breeding and commercial eel farming sites in Can Tho city. Mr. Nguyen Thanh Tan, owner of Binh Thuy farm, Long Tuyen ward, Binh Thuy district has implemented the eel farming model in the form of water circulation since 2019, on a test area of ​​30m2, including 5 tanks, each tank is 6m2. The culture tank is designed to connect to the water circulation system including a biological filter tank, a solid waste settling tank and a water tank. The flow of water through the aquarium is adjusted from 0.5-0.8 liters/min. Black nylon rope is tied into a beam with a length of 20-30 cm, used for sheltering eels. This cord is cleaned daily and renewed once a month. Model of an eel tank based on water circulation technology. (Photo: Anh Tuyet/VNA) Eels are incubated for 90 days, size from 1.4-3.2g/head. Eel feed is industrial pellets, with 41% protein content. Instead of having to change the water every day like the old model, in the water recirculation model, the water is changed every 2-3 weeks. This helps farmers reduce labor costs, water costs, as well as help stabilize the water quality of the aquarium, and the eels are healthier and faster. After 8-9 months, commercial eels can reach 400g / head, farmers’ profits doubled compared to the old model. “In the commercial eel farming group of Binh Thuy district, there are currently more than 10 households out of 40 members who have switched to raising eels using water circulation technology. In general, the model is quite easy to install, the initial cost is The income is not high. The members are aware of supporting each other in farming techniques as well as product output. Therefore, most of the farming households give quite positive feedback,” said Mr. Tan. According to Associate Professor, Dr. Pham Thanh Liem, in the near future, the model will be replicated in Ninh Kieu and Phong Dien districts. The purpose is to support farmers to increase the technology content in farming and farming.

Kariko Katalin. Photo: Euronews What is mRNA technology? Vaccines with mRNA technology are Covid-19 vaccine most awaited. The US Food and Drug Administration (FDA) pioneered and quickly approved this vaccine. Compared with traditional technology, mRNA promises to be more effective, faster, safer, with fewer side effects; can compare the difference like a motorbike and a jet. The concept of mRNA was learned in 9th grade, biology lectures taught that mRNA has the function of conveying information that regulates the structure of proteins. Letter m = messenger = information. To make it easy to understand, the process of synthesizing each protein in the human body is like solving a complex math problem, mRNA becomes a manual of mathematical formulas. If humans can create a vaccine in the form of artificial mRNA, when injected into the body, the mRNA will disguise itself as a “thief” that sneaks in but does not wake up the “host”, it silently builds a defense system. are antibody proteins, so that when the virus attacks, it will be destroyed by that system. mRNA urges, haunts Kariko Katalin Kariko Katalin is obsessed with mRNA, she understands this is a very special type of RNA that holds all the secrets to creating billions of billions of proteins in the human body. Theoretically, science can completely manipulate mRNA to create a targeted protein, doing that, mRNA becomes the most powerful weapon to control a variety of diseases. But that’s just a theory. Understanding of mRNA in the 1980s was still very limited. In principle, when injecting mRNA into the human body, it is an allergen, so the body’s defense system will immediately destroy it before the mRNA can perform its functions. That is, the mRNA vaccine, no matter how cleverly disguised, is still a “thief”. But what is more serious, is that the human body’s instinctive resistance to the “thief” is too strong, creating a severe immune response that is potentially fatal. After a lot of failures, most scientists gave up, no one cares about mRNA anymore, that knowledge is scattered on the pages of 9th and 10th grade biology textbooks, so that students can take exams with these questions. boring question. Kariko Katalin was undaunted and continued to dive into research. All efforts paid off when Katalin’s work attracted the attention of two young companies Moderna (Canada) and BioNTech (Germany), after which the giant Pfizer (USA) decided to invest in the production of Covid vaccines. -19 by mRNA technology. That is like winning a ticket to Mars. mRNA technology will not stop at vaccine production, but in the not too distant future, a series of “diseases” such as cancer, stroke, or other dangerous diseases also promise to be “cleared”. The floating life of Kariko Katalin Kariko Katalin was born on January 17, 1955 in Szolnok (Hungary), in a cottage without amenities, but full of love for a family home. Kariko Katalin inherited a gene for biology from her father, a pork salesman, a gene for research perseverance from her mother, an accountant, and was inspired by her passion for biology from the teachers at the school she attended. study. Due to poverty, Kariko Katalin devoted herself to her university years, winning a scholarship to the People’s Republic of Hungary, the most prestigious scholarship at that time. Katalin went on to study for a doctorate, then worked at the biological research center of the Hungarian Academy of Sciences in Szeged. Kariko Katalin pursues mRNA technology. It is an area that requires a lot of investment. Hungary in the 1980s was the most liberal and open country in the former Soviet bloc, but it also didn’t have the money to fund major research. Kariko Katalin lost her job at the age of 30. She initially looked for a job in the European Union, but nowhere would accept it, because Katalin had no significant scientific achievements. One afternoon in 1985, Kariko Katalin and her husband took their 2-year-old daughter out of Hungary to find her way to America. The only asset of any value is the old car, which sold for £900 on the black market. To make it through, Kariko Katalin had to cut open her daughter’s toy teddy bear, insert £900, and then sew it back up. Initially in the US, Kariko Katalin was accepted to work at Temple University, but soon her group was disbanded because of lack of funding. In 1989, Kariko Katalin joined the faculty of pharmacy at the University of Pennsylvania. Although she is a full professor, this is the most difficult time, the salary is very low and no one believes her. Things took a turn for the worse in 1995, Kariko couldn’t get funding, couldn’t find a project, and the University of Pennsylvania decided to fire her. It was a horrible time. The room Kariko Katalin lived in was leaking in every evening rain. She has just been diagnosed with cancer while her husband is in Hungary and cannot come to the US because of visa problems. How much time and dedication work seems to be slipping out of hand. “I started to suspect that maybe I wasn’t good, I wasn’t smart. I try to tell myself that everything is here, I just need to do better experiments,” said Kariko Katalin. Turning point In 1998, Kariko Katalin finally received the first $100,000 grant. Strangely enough, that year she also met a man of her life. It was that fateful afternoon, Kariko Katalin went to photocopy documents, she met Drew Weissmen, a colleague who had just moved from the National Institutes of Health. In the meantime, Kariko Katalin told Weissmen about the idea of ​​creating mRNA. Immediately Weissmen saw before his eyes a priceless fortune. Weissmen decided to invest, collaborate with Kariko Katalin, determined to develop mRNA technology in the field of biomedicine. In 2005, the attenuated version of mRNA was released. After reading the study, Derrick Rossi, a Canadian stem cell expert who is doing a PhD student at Stanford University, was amazed. The time has come. Realizing a super profitable business opportunity, Rossi quietly sought investment capital, he founded a small company, named Moderna. In Germany, a new research team also discovered the potential of Kariko Katalin, a new company BioNTech was founded, based in the US. In 2013, BioNTech hired Karko Katalin as a senior mRNA specialist. Moderna and BioNTech did not do much until 2020, when the Covid-19 pandemic broke out, Moderna promoted the production of vaccines by mRNA technology, adding the company BioNTech invested by Pfizer billions of dollars determined to turn their ideas into Kariko Katalin come true.

The Revenant (2015) Movie content: The Revenant is based on a true story, the film tells the story of the hunter Hugh Glass (played by Leonardo Dicaprio). After a bloody battle with the Native Americans, Hugh was wounded and ruthlessly abandoned by his comrades in the snowy mountains. From there, Hugh Glass must do everything to survive the brutal cold, predators and war with the tribes in the wilderness. Thanks to his strong will, the hunter miraculously survived, crossing a distance of more than 3,000 miles (4,828 km) alone to return and take revenge on John Fitzgerald (played by Tom Hardy) – who was once the old friend of mine. The scene where Hugh Glass (Leonardo DiCaprio) is attacked by a mother bear is one of the most spectacular and unrealistic moments in this movie. The bear used its claws and fangs to bite and jump on Hugh. You may not know: The bite force of the gâú is 1,160psi (it’s like a human biting a sausage), their claws are 10-15 cm long and their weight is about 300-400 kg. You see, no one can survive such a war. Another strange point is that the grizzly bear attacks the main character because he is a threat to its cubs. For a mother, nothing is more important than protecting her cubs, but the bear just stops in the middle of a fight, leaving the opponent alive and gone. In another scene, Glass takes off his wet clothes and gets inside the horse’s belly to keep warm. It was a method used by many soldiers during the war, but…the main character spent the whole night inside the horse. Since the snow was everywhere, the temperature was definitely below zero and the horse’s corpse was dead. will freeze after a few hours. If it was in real life, Glass would have no chance of coming back alive the next morning. He could freeze to death in the night. In short, although “The Revenant” is based on a true story, we should only treat it as a feature film. The Leader – Alpha (2018) Movie content Alpha: The Leader is an ambitious action-adventure film from Sony. Not only possessing an overwhelming exterior depicting the majestic ancient world, the work also embraces an extremely touching scenario. The film is the story of the feud between a prehistoric boy (Kodi Smit-McPhee) and a stray wolf. Also from here, human history completely changed. In this movie we enjoy the majestic landscape and beautiful friendship between a boy and a wolf. But there are many mistakes in the movie that are quite obvious. The beginning of the film is the fight of a boy and a buffalo. But you can’t say it’s a war either: The animal just attacked the boy, and if it were in real life, he’d be broken/paralysed. At the end of the attack, the boy falls from a rock but only dislocates his hip. The wolf’s behavior is also quite strange. Its injuries don’t look too serious and a wild animal would rather follow its pack than stay with its enemies – a wolf can still walk on three legs. . Talk a little bit about the appearance of the wolves. We see prehistoric mammoths and saber-toothed tigers in the movies, but the wolves in the movie look like today’s wolves and are no bigger than a normal dog. How can they survive in a world full of giants? The Meg – The Meg (2018) Another recently released movie about a giant shark. It is difficult to judge the appearance and behavior of prehistoric monsters, but all creatures will be subject to certain biological laws. The size of the shark in the film is described as 70 – 75 ft (21.3 – 22.8 m) long. But scientists think its size was 60 ft (18 m). One of the heroic characters in the movie also said that such a shark could easily bite a whale in half. But they do not specify the size of the whale. What do we imagine when we think of whales? It is true that there are really huge whales. But there are whales that are only 13 – 16 ft (about 4 – 5 m) long like the dwarf sperm whale, while the size of a blue whale is 110 ft (33.5 m) – almost twice the size. shark size. As for bite force, sharks can bite a whale in half. But can the shark expand its jaws to that extent? Scientists have proven that megalodon can attack whales, but these whales must not be too large, only 40 – 50 ft (12 – 15 m) long. Sometimes in the movie, the shark attacks only one person (one of the main characters). But scientists don’t think this is characteristic of prehistoric predators. They will not chase 1 or 2 humans, but may swim to attack places with many people (such as the beach). In the beach scene at the end of the movie when the megalodon hunts on the beach, the shark approaches people swimming far from the shore and opens its mouth to swallow them, however it suddenly hears the sound of whales and swims away. . But in reality, it would have easily swallowed the prey that was lying right under its nose and continued to attack other victims.

Covid-19 shows that the future of the world is biological, not digital. (Source: CNN) Millions of people around the world are viewing images of desperation in many parts of India as infection rates exceed 300,000 cases per day. Reports show severe hypoxia in the South Asian country with a double-strain variable, accompanied by images of corpses waiting on pavements, when crematoriums become overwhelmed, even. in the capital New Delhi. At the end of March, the World Health Organization (WHO) released a draft report on the origins of the Covid-19 pandemic with findings that many have come to expect: SARS-CoV-2 virus may have been Spread from animals to humans. It can be said that the uninteresting cause has caused the biggest global turmoil in a century, and just as it has caused many earlier pandemics in history: Human card in nature. At the same time, the world may be coming to the end of an era of digital hype. Sharp warning For years, it has been said that digital technology will lead the world to a future without scarcity. Yet the reality of the pandemic is a sharp warning about how the real world can reverse fantastical, unrealistic delusions. Every new technological advance promises a fundamental transformation of society, eliminating inefficiencies and inequality and empowering people through division of labor. Blockchain technology, artificial intelligence and 3D printing technology are hailed as the leading flags bringing about major changes in lifestyles and working, not only in developed countries but also in underdeveloped countries. lice in countries with no basic living conditions. The belief in technology may even be reflected in the Western response to the pandemic. Instead of considering the social commitment citizens engage in – placing the collective interest above individual rights by requiring masks and implementing other restrictions – and having a strong public health response, rapidly to control the Covid-19 outbreak, Western countries were again hoping to develop vaccines as a last resort, and at the cost of large-scale economic disruption and commodity disruption. hundred thousand people died. In the US alone, a study has shown that hundreds of thousands of lives could be saved during a pandemic if previous regulations on blockades, masking and social segregation were strictly enforced. . The SARS-CoV-2 virus has caused global chaos because of its ability to enter the human body through biological transmission and disrupt the functioning of organs in the body. Vaccines that prevent viruses are seen as a mechanism that promotes the human body’s natural response to infection. If humans want to avoid another global health disaster, humans need to restrain their growth, stop attacking natural and biological systems based on the argument that all other living entities must be subordinated. for human development. The need for economic development has destroyed the natural world so much that disasters such as the Covid-19 pandemic are more likely to occur as population and human greed lead to self-exploitation. course more. The time has come to stop these attacks. Maintain integrity and resonance Human survival depends on maintaining the integrity and resonance of natural systems and internal biological processes. That includes habitats, objects that enter the human body (pollutants and viruses), things people consume (water, air and food), and the biological effects of waste produced by children. maker. During the early months of the pandemic, reports showed that the Earth was benefiting from reduced greenhouse gas emissions, as the majority of the middle and upper classes could study remotely and work from home. However, the switch to working from home is not without consequences for the environment. The more secluded lifestyles have to depend on people who work in the real world, produce and process food, feed the groceries and deliver food to people at home. Goods ordered online still have to be transported by means of transport such as ships, vehicles and need to be delivered by the delivery person. Meanwhile, infrastructure in the real world has been deeply affected by the Covid-19 pandemic. Essential workers around the world, whether in hospitals, meat packers in the US, construction sites in Singapore or glove manufacturers in Malaysia, have all been hit hard by the boom. Play by Covid-19. This suggests that we not only need to limit encroachment on the natural world, but also need to invest more in basic protective measures (also known as “guaranteed resilience”) such as supply. safety and assurance of food, water, sanitation, housing, a good public health system and access to energy. Forecasts suggest that the human population will peak 10 billion by 2064, and greater pandemic risks will accompany other man-made threats, from climate change and biodiversity loss to Vulnerable food systems and limited available land. Digital technologies can play a role in mitigating and countering such threats only when people are imbued with the fact that human existence is fragile and fully dependent on a suitable biosphere. The sooner people realize that truth, the sooner people can be sure that technology development efforts are put into ideas that really help people, and not in utopian plans. should come from the narrow definition of human evolution.

Black-headed caterpillars cause 70-80% damage in the coconut orchard they appear. According to the Department of Agriculture and Rural Development (Agriculture and Rural Development) of Ben Tre province, since the discovery of the black-headed pest in July 2020 to the beginning of April 2021, the whole province of Ben Tre has more than 160 hectares of coconut orchards. black attack, in which the area heavily infected with burnt leaves was 51ha. This is the area where more than 40% of the leaf boats are damaged out of the total number of leaf boats surveyed based on the guidance of the Southern Plant Protection Center (Plant Protection Department). Currently, the blackhead worm continues to cause harm in districts of Binh Dai, Chau Thanh, Mo Cay Nam, Mo Cay Bac, Ben Tre City and Cho Lach. The largest outbreak was in Huu Dinh commune of Chau Thanh district with over 66ha of infected coconut orchards. Mr. Dang Thanh Hai, in Huu Nhon hamlet, Huu Dinh commune, has 2,000 square meters of coconut over 40 years old that are being attacked by blackhead worms, causing heavy damage. Mr. Hai said that because the coconut tree is 30-40m high, it is impossible to spray this insecticide, so he had to destroy it. “Coconuts grown for a long time, used to suffer many diseases but did not die, now the black-headed worm eats them, causing mass death of coconuts, irreversible. Blackhead worm is very dangerous because it eats coconuts very quickly, within 2 months it has spread, cannot be cured “- Mr. Hai said. Up to now, the areas of coconuts heavily damaged by blackhead worms in Phu Long and Dinh Trung communes, Binh Dai district, are basically controlled by functional agencies. However, the application of mini aircraft to control the epidemic is ineffective. In other harmful blackhead worm detection locations, the Department of Agriculture and Rural Development has coordinated with local authorities to organize workshops and trainings to guide farmers in implementing control measures. Up to now, farmers are basically aware of the harm level as well as basic control measures, self-treatment and spraying. Mr. Phan Tan Loc, Head of Agriculture and Rural Development Division of Chau Thanh district, said: “The black-headed worm attacked about 80 hectares of the district’s coconut garden. The locality has organized the spraying of drugs according to the instructions of the authorities, but it is not effective. Therefore, the district proposes the Provincial People’s Committee to extract funding for researching special treatment drugs, soon going to the army to spray simultaneously to stamp out the epidemic, to avoid widespread spread; deploying extensive propaganda to people about temporary management measures for people to know and implement ”. Implement temporary management measures The black-headed worm attacked the coconut garden in Ben Tre. After the outbreak of black-headed worm, Ben Tre Plantation and Plant Protection Department coordinated with Southern Plant Protection Center to take samples of harmful pests and send identification samples. Center for Plant Inspection and Inspection, the Plant Protection Department has identified this pest with the scientific name Opisina arenosella Walker – a serious pest originating from southern India and Sri Lanka. In Vietnam, the blackhead worm that harms coconuts is a new pest that has not been researched and has a registered pesticide for control. Therefore, the Plantation and Plant Protection Department of Ben Tre province has issued a temporary control measure based on the reference information of the Southern Center for Plant Protection and some actual records of the unit. At the same time, to carry out propaganda and training on knowledge of blackhead pest prevention for farmers in Ben Tre. In addition, the District Plantation and Plant Protection Station also actively coordinates with relevant sectors to actively propagate, organize training courses, guide coconut farmers to recognize and manage blackhead worm. . Regarding the temporary management measures, the Department recommends that farmers regularly visit the garden to timely detect and implement preventive measures. In case of detecting a black-headed worm, people quickly prune, destroy leaves and leaves that are damaged by worms, burn or bury them in water to reduce the pest population effectively and safely for people and the environment. . This is an important and necessary measure to take immediately after a pest is detected. People should also balance fertilizer, divided into many fertilization times a year. Mr. Huynh Quang Duc, Deputy Director of the Department of Agriculture and Rural Development of Ben Tre province, said: The view of the Ben Tre Agriculture sector is to coordinate with companies and businesses inside and outside the province to immediately apply quarantine measures to reduce honey. number of worms, limit the spread while waiting for research results to have a complete process. Pest control with the motto of environmental protection, organic coconut production has been successfully built by businesses and farmers. To stamp out epidemic diseases, but ensure a stable production environment and especially protect people and animals living under coconut canopy … In the long term, deep management of blackhead by biological means to ensure the environment, ensure the quality of coconut products with the quality of food safety accepted by the domestic and foreign markets. According to Mr. Duc, Ho Chi Minh City University of Agriculture and Forestry is speeding up the implementation of the project “Research and assessment to determine the harmfulness of coconut leaf-eating worms and build models and propose solutions. biosafety management and prevention in the province of Ben Tre ”to apply results in production. The school has set up a room for propagating parasitic bees at the Department of Planting and Plant Protection, expanding one room at the Center of High-tech Agriculture to both research and release quickly parasitic bees. Good on black-headed worm pupae and larvae. Mr. Vo Van Nam, Head of Plantation and Plant Protection Department of Ben Tre province, said: The Department has recorded many natural enemies of the black-headed worm that harms coconut in gardens in Binh Dai district. Typically, parasitic bees, stink bugs catching prey, weaver ants, pincer beetles … Therefore, the Ben Tre Department of Cultivation and Plant Protection recommends that people choose pesticides that are less toxic, less harmful to the kind of natural enemy. In the coming time, will aim to control blackhead worm with biological measures because Thailand has successfully applied this measure with parasitic bees. In addition, the Department is also cooperating with the Ho Chi Minh City University of Agriculture and Forestry to conduct research as well as to breed this natural enemy. “Can Tho University has also studied and tested a probiotic to prevent blackhead worms with plant extracts. Initial testing on some infected areas has been effective, farmers are very excited. Ben Tre is building organic coconut gardens, so the protection of these coconut areas with bio-products is extremely necessary. Next time, this unit will continue to test to complete the process and products. If the product continues to achieve high efficiency, we will put into the process to recommend farmers to use “- Mr. Nam said.

After nearly thirty years of hard work with organic agriculture, with the fire from the head, Chairman of Que Lam Group Nguyen Hong Lam, up to now, Que Lam has built a circulating agricultural ecosystem. Farming and Ranching. That ecosystem includes 14 member units operating throughout the country, to both Cambodia and Laos, 8 microbiological organic fertilizer factories, and thousands of models linked with farmers in provinces. and especially the 4F complex in Thua Thien – Hue province, the first 4F complex in Vietnam. It is important that with the persistence and steadfastness on the journey of organic farming, the Que Lam Group has contributed to changing the perception and thinking of farmers, scientists, and managers in this field. . If in 2018 there were only 32 provinces accompanying Que Lam on an area of ​​nearly 60,000 hectares of crops, by 2020, 51 provinces and cities will join in on an area of ​​more than 100,000 hectares. These are very encouraging results, showing that awareness of an organic agriculture has changed the landscape of agricultural production in Vietnam.

Tests with neutrobots have been performed quite successfully in mice. It can use intelligent biological camouflage and overcome difficult barriers to get closer to the source of the disease in the body and offer the best treatment. The Preeminence of New Micro Robots Microbots are nothing new, it’s like disguising robots into bacteria or using magnets to move them across blood vessels. But what sets Chinese scientists’ new micro-robot designs apart from the crowd is that it can overcome one of the body’s toughest biological barriers, the blood-brain barrier (BBB) ​​- a single layer. extremely high selectivity protection. Designed to stop pathogens and allow only nutrients to penetrate, BBB is the challenge of micro-robots that the body often considers an outside invader. It is very difficult for micro robots to cross this last line of defense and get closer to the hidden tumors behind it. One author of the above study is Professor Zhiguang Wu at Harbin Institute of Technology specializing in nanotechnology. The new micro-robots, he said, can overcome obstacles that hamper many conventional medical treatments. According to Professor Wu, “the passive diffusion of conventional drugs is subjected to a long, ineffective period of time and blocks biological barriers, which can lead to strong side effects. Meanwhile, the new swimming micro-robot / nano-robot, can move into hard-to-reach tissues using their propulsion, load different drugs and actively swim to diseased sites to transporting drugs ”. This is very important because when it comes to fighting cancer because the more targeted the treatment the better. It is especially true when it comes to brain tumors. Because the tumor is in a difficult position in the brain and BBB’s strong protection, drug treatment can be difficult, and removing the tumor requires brain surgery. Even then, usually only 90% of the tumor can actually be removed. In the past, micro robots were inspired by the way a bacteria or sperm move through the body. All light, acoustics and magnetic fields are used to propel them along the host’s body. Through it, a variety of biomedical tasks can be performed, including cutting the membrane, retaining the distributed drug in the gastrointestinal tract, and distributing the drug through the eye dropper. However, even though the researchers control the motion of these micro-robots more than typical drugs in the body, most micro-robotic designs still face one major hurdle: the body’s immune system, especially BBB. To fool BBB’s defense systems, scientists have designed a new micro-robot that is biologically camouflaged to “sneak through” the fence without being detected. The neutrobots are disguised and introduced into the bloodstream. How does the new micro robot work? The use of self-propelled, drug-dispensing micro-robots could open the door for scientists to get closer and more individual-based access to tumor treatment than oral or given medication. permission before. To treat glioma, a type of brain cancer, in mice, Professor Wu and colleagues have designed neutrobot-based micro-robots that can be controlled with a magnetic field. First, they created nanoparticles from a gel embedded with magnetic iron oxide particles, and the popular cancer drug paclitaxel. Next, these nanoparticles were encased in a disguised E. coli bacterial membrane. Disguised as harmful bacteria, these nanoparticles are submerged by in vitro mouse neutrophils much more easily than the bare nanoparticles that are not camouflaged. The researchers found that the camouflage also prevented drug leakage and made these particles less toxic to neutrophils. The research team tested the neutrobots’ ability to navigate and deliver drugs in vitro. Under the control of a rotating magnetic field, the neutrobots reach a speed of 16.4 µm / second – about 50 times faster than the natural neutrophil. By tracking the neutrobots under the microscope, the scientists can let them travel in complex directions on the artificial substrate. In their trials, the team showed that their neutrobots were able to successfully penetrate mouse BBBs to bring the drug into brain tumors. Despite these successes, scientists still have many things to do before they can be applied to humans. One issue that needs to be fixed, the authors explain, is how to better track each neutrobot as they pass through the body. Right now magnetic resonance imaging can track neutrobot groups as they move but cannot track individuals. “Our research has verified that treatment with neutrobots can prolong survival in mice with gliomas. Therefore, it may not be too long to bring stories about micro-robots in science fiction to reality, ”said Professor Wu.

【Xin Zhiyuan Guide】A new generation of Xenobots-They are assembled into the body automatically through single cells, and after assembly they can be moved without the aid of muscle cells, and even demonstrated the ability to store memories.

Last year, a team of biologists and computer scientists used frog cells to create a new type of miniature self-repairing biological robots called “Xenobots”-biological machines that can move around, push heavy objects, and even make Group behavior.

Today, the team has successfully developed a new generation of Xenobots on this basis-they are automatically assembled into a body through single cells, and can be moved without the aid of muscle cells after assembly, and even demonstrated the ability to store memories. The new generation of Xenobots robots move faster, can move in different environments, and have a longer service life. At the same time, they still have the ability to teamwork and can repair themselves after being damaged.

Researchers say that this versatility makes it possible for Xenobots robots to perform tasks in more environments. Relevant research results were titled “A cellular platform for the development of synthetic living machines” and were published in Science Robotics magazine on March 31.

Shuttle at will, just because of this special “leg”

It is understood that the researchers used artificially “modified” heart cells in the previous generation of Xenobots robots. Due to the natural rhythmic contraction of these cells, Xenobots robots have the ability to move around.

In contrast, the new generation of Xenobots robots adopts a “bottom-up” approach. The extracted frog stem cells self-assemble and grow into spheroids. The cells in some spheroids will differentiate to produce cilia-like tiny hairs after a few days. Protrusions, these protrusions can move back and forth or rotate in a specific way.

The corresponding author of the paper, director of Allen Discovery at Tufts University, and professor of biology, Michael Levin, said: “We are witnessing the plasticity of cell clusters. Although these frogs have completely normal genomes, we use their cells to construct A new’body’ completely different from the default state.”

At the same time, these cells can also reuse their genetic coding hardware to achieve new functions, such as using cilia to achieve movement. Even more surprising is that they can not only take on new roles spontaneously, but also create new physical behaviors without the need for long-term evolutionary selection of these characteristics. ”

Figure | Xenobots move through cilia and show teamwork ability

In order to test the ability of a single Xenobots to move in different environments, the researchers constructed different experimental environments from a completely open field to a restricted capillary with an inner diameter of 580nm. In all cases, except for some Xenobots that were challenged in narrow passages, Xenobots were able to move in space.

Under certain circumstances, Xenobots may move in the opposite direction. The reason is that the intracellular and tissue-wide polarity is established by cell rearrangement during the self-assembly stage created by Xenobots, and cannot be changed on a short time scale. Therefore, the rapid changes observed in the study may be due to real-time control of cilia, such as changes in the beating frequency of individual polyciliated cells, rather than changes in structural polarity.

Like many unicellular and multicellular organisms that use cilia for exercise, this exploratory behavior (spontaneous changes in exercise) may be affected by random internal physiological processes and micro-changes in the environment, such as spontaneous currents in an aqueous medium.

In the experiment, when the channel width of the “maze” is reduced to 2mm, Xenobots will continuously hover around a wall of the maze. According to observations, most Xenobots tend to exhibit an elliptical movement pattern. This behavior may be due to the wall inhibiting the completion of the elliptical path, which in turn drives the final directional movement.

Figure | Xenobots can pass through a variety of terrains including mazes

In addition, the researchers placed Xenobots on one end of a 2cm capillary with an inner diameter of 580nm. Unexpectedly, 42% of the tested Xenobots were able to pass through capillaries end to end. All individuals exhibiting movement successfully passed through the entire capillaries, and none of them stayed or reversed in the middle between the two ends. To movement.

Figure | Xenobots through tiny capillaries

The researchers said that these data are sufficient to show that Xenobots can successfully traverse various environments without having to go through a special configuration to adapt to a given scene, which is an ideal feature in many software robot applications.

Stronger collection and handling functions

At the same time, the researchers also modeled Xenobots of different shapes to determine whether they exhibit different behaviors when they are alone or in a “team”.

They hope that Xenobots can do some meaningful work in real life, such as life tools for removing microplastics in the ocean or pollutants in the soil. Facts have proved that the new generation of Xenobots is faster and better than the previous generation model in tasks such as garbage collection. They can clean the petri dishes in groups to collect larger iron oxide particles.

Figure | Xenobots work together to collect piles of tiny particles

In addition, Xenobots can also cover larger flat surfaces or move in narrow capillaries. These studies also show that in the future, computer simulation can optimize the additional functions of biological robots to adapt to more complex behaviors.

Also has a memory function? !

The core feature of robotics is that it can record information and use this information to modify the actions and behaviors of the robot. In order to confirm whether Xenobots have this function, the researchers designed a Xenobots with read and write functions, and they used EosFP’s fluorescent reporter protein to record this information. This protein usually emits green light, but when exposed to 390nm wavelength light, this protein can emit red light.

Researchers injected messenger RNA encoding the EosFP protein into the cells of frog embryos. Xenobots made from these stem cells have a built-in fluorescent switch that can record blue light exposure around 390nm.

To test the memory function of Xenobots, the researchers let 10 Xenobots move on a surface where a spot is illuminated by a 390nm beam. Two hours later, they discovered that three robots were emitting red lights, while the rest remained green, effectively recording the robot’s “travel experience.”

Figure | Xenobots can record information by changing the color

In the future, this proof of the principle of molecular memory can be extended to detect and record light, radioactive contamination, chemical pollutants, drugs, and diseases. The further design of the memory function can record multiple stimuli, allowing the robot to release compounds during the stimulus, or to change its behavior based on the sensation of the stimulus.

Bongard said: “When we give robots more functions, we can use computer simulations to design more complex behaviors and the ability to perform more complex tasks. We can not only report the conditions in their environment, but also modify and Repair the conditions in its environment.”

Even self-healing

What’s more surprising is that the new generation of Xenobots is also very good at “healing” their wounds, and can heal serious full length lacerations by half the thickness within 5 minutes of injury. In the experiment, all the injured robots eventually healed their wounds, restored their original shape, and continued to work as before.

Figure | Xenobots can repair itself

The researchers said that one of the advantages of biorobots is metabolism. Unlike metal and plastic robots, the cells in biorobots can absorb and break down chemicals and work like small factories such as synthesizing and expelling proteins. The entire field of synthetic biology previously focused on reprogramming single-celled organisms to produce useful molecules, and now it can be used in these multi-celled organisms.

Like the previous generation, the upgraded Xenobot robot can survive in the embryonic energy store for up to 10 days and run tasks without additional energy. However, if they are kept in a nutritious “soup”, they can also run at full speed for several months.

Before, Levin introduced a wonderful description of biological robots in a TED talk, and he also described what we can learn from these biological robots. He not only described the great potential of micro-biological robots to perform effective tasks in the environment or potential therapeutic applications, but also pointed out the most valuable benefits of this research, using robots to understand how individual cells gather, communicate, and specialize to create greater The organism. This is a new model system that can provide a basis for regenerative medicine.

The researchers said that Xenobots and subsequent alternative versions are also expected to provide information on how ancient single-celled organisms evolved into multicellular organisms, as well as the origin of information processing, decision-making, and cognition in biological organisms.

Only PDO is also used to help lift and slim the nose shape, remove dark circles, puffiness, reduce crow’s feet, aging wrinkles in the smile groove, making the face a few years younger and increasing vitality quickly. without relaxation. This method is less risky if performed by highly skilled cosmetologists. The doctor who knows how to combine acupuncture will know how to implant just to create aesthetics and improve the health of the woman from the inside, making the beauty more complete.

Only Bio Meyisun is currently being imported and distributed exclusively in Vietnam by Hoang Binh Trading Services Company Limited (HB Medical). This is a type of criteria with European quality standards (CE) continuously from 2012 to present, produced by 21 Century Medical, the largest manufacturer in Korea with 23 trademark copyrights on self-criteria. biology and aesthetic needles.

Ms. Hoang Thu Ha, General Director of Hoang Binh Trading Service Company Limited

Ms. Hoang Thu Ha, General Director of Hoang Binh Commercial Service Co., Ltd. shared: “In beauty salons in Vietnam, people call Bio Meyisun bio only collagen because when put this thread in the dermis, the Skin cells are stimulated to mobilize, in this process endogenous collagen makes the skin shiny, brighter and more beautiful than before “.

Biological self-digestion thread (PDO) is the type that has only been used to sew medical incisions for more than a decade. Only PDO Bio Meyisun is capable of spontaneously self-destructing over a period of 6 to 8 months. This type of thread has been improved through the needle in many different forms to serve the aesthetic purposes of the Korean cosmetology industry since 2011.

Biological self-destruction is a remarkable step forward in the health industry when it has been proven effective and safe in clinical practice.

In 2012, self-targets started to be applied in Korea in the field of aesthetics. Foreseeing that trend, in 2013, Hoang Binh Trading Service Co., Ltd. officially imported and distributed in Vietnam. Each new criterion appears with more superior features and is applied in major hospitals as well as spas and beauty salons across the country …

In the medical facilities, reputable aesthetics will always focus on using only quality. Only biological aesthetic is certified to be highly adaptable and safe to use for the human body. However, this product is present due to the emerging market demand, the types of thread that are not of good quality such as the easy-to-puncture and the standard decomposition time, the low-quality needles are not sharp and are not produced according to the market. In compliance with safety standards, buyers need to know to distinguish standard goods with full safety documents and are legally distributed by reputable companies with import permits from the Ministry of Health. Ms. Hoang Thu Ha said: “Only implanted in the body to beautify and improve health, so users need to be strict about safety standards. If the product is of the right quality as announced, self-destruction is a great “weapon” for doctors because the implantation method only helps the body to heal itself from the inside, gradually dealing with the root causes of the disease. without taking medicine. This is a promising approach to the future ”.

Thuy Nga and Kim Ngan’s mother.

Kim Ngan became crazy because he saw the bloody shooting scene

In Ms. Huong’s memory, Kim Ngan is a cute, obedient and filial girl with her mother. When she was a child, she attended French school. She hired a private teacher to teach her, so she studied very well. She was mostly ranked 1 – 2 in her class during the five months of her studies. From a young age, Kim Ngan was cute, everyone wanted to pamper and took pictures of children.

When she came to America, Huong met her old friend, the wife of musician Truong Hai. This musician found Kim Ngan too beautiful, so he invited her to record a song as well as take pictures to print on the cover of the music tape. Unexpectedly, how much was released was not enough to sell. Since then, Kim Ngan became a singer. According to Ms. Huong, her daughter is very gentle, very sociable with her colleagues. Concurrent singer like Lynda Trang Dai can confirm this.

Kim Ngan married at 19 years old, divorced at 29 years old. At that time, everything kept going one by one. Kim Ngan struggled to settle the divorce, so business was so unprofitable that he had to sell his own record label to return to Los Angeles. She brought her 2 little girls home. At that time, Huong was still in the US, the whole family of 4 generations lived together.

At that time, the court tried Kim Ngan custody of the children. The ex-husband, father of two girls, named Bắc is allowed to visit the child. He loves his son very much, so every time he comes to visit, he takes his children to go out and go shopping. buy a lot of clothes, toys. Therefore, the two children insisted on staying with their father. Although Kim Ngan loves her children very much, but thinks she has failed, she has no money left, so she let her ex-husband take care of the children. At that time, my daughter was only a few years old, my second child was one year old.

Young Kim Ngan beauty.

After that, Ms. Huong returned to Vietnam to open a clothing shop and go between the two countries. During this time, Kim Ngan had a new boyfriend and became pregnant with this person. “There is no such thing as Ngan wandering the street and being raped and pregnant,” said Huong.

According to Huong, Kim Ngan’s third son currently lives with his father in Fullerton, California. The boy is handsome, educated and active, always asking who his mother is. Kim Ngan’s ex-boyfriend promised that when he was an adult he would let him take back his mother.

Also during the time when Mrs. Huong was in Vietnam, Kim Ngan went to a dance hall in Canada and had an incident that changed her life. While she was acting, a scuffle happened that caused a woman who had been hit by a bullet to die in a pool of blood. Kim Ngan was so scared that she had just returned to the US and ran to her sister’s house, crawling under the table and trembling. Since then, wherever the sister goes, she will not leave.

“From a young age, Ngan was already mentally weak. A woman like that went to the end again, with no money, no name, no husband and children. Later, the event of seeing the person shot dead, Ngan became mad. The frightening thing is that the female audience who got hit by the bullet has not died. sweetly told.

Kim Ngan is sick but knows who loves her to love her

Mrs. Huong is very sad because since Kim Ngan was mentally ill, she did not allow anyone to access, including her mother. At first, the singer was still close to her mother to eat and go shopping. She used to rent a room for the mother and daughter to live in.

One evening, Kim Ngan said the chattering was very loud, she was deaf in one ear, so all the sounds pressed into the other ear gave her a headache and could not sleep. She told her daughter: Ngan, you should go inside and lie down, let your mother stay out, you talk too loudly, you can’t sleep. Unexpectedly, Kim Ngan got angry, left, and was no longer in that room.

Those who love Jun Pham are familiar with the image of a male singer and a close father as friends. However, to be able to freely express the feelings as at present, the father and son have had to go through many difficulties, together trying to remove misunderstandings and problems.

Singer Jun Pham Hui talked about memorable memories with his father.

Like many other sons in the Vietnamese family, Jun Pham used to be unable to talk freely with his father. According to Jun Pham, his father is a strict person, so all the joys and sorrows in life are confided to his mother. Things kept going like that until the incident happened to his family, his mother passed away.

“At the age of 18, Jun’s mother unfortunately passed away. At that time I was lonely because I couldn’t share with anyone. The sadness, the change in puberty, the worries about going to college …, I can’t tell my dad. Because my dad is a man, sometimes I don’t understand and can’t share it. At that time, I was just selfish thinking for myself but didn’t understand that I lost my mother, but my father also lost my wife. I must be very sad too ”, Jun Pham said

The male singer also said that at that time, he could not accept the fact that his father went out for a drink every night, leaving him at home. When the anger peaked, the father and son had a quarrel so loud that the male singer intended to leave home. But the very next day, the hypertensive father was hospitalized and Jun Pham felt extremely sorry.

“At that time, I realized that I was so bad, I only cared about the past but forgot how important the present is. At that time in the hospital, I just sat holding his father’s hand and said sorry, promising that from now on I will always admit my mistakes “- Jun Pham recalled.

According to the male singer, thanks to that argument, the father and son understood each other better: “From that day on, Dad became lighter. I understand that he lost his very loyal wife, how could he get used to it. My father changed my mother to support me and I changed my mother to take care of him, it happened for 10 years. For those 10 years Jun tried to stand by his side to understand, he also tried to stand on Jun’s side to understand … so that now the two of us can love each other more, easily saying things like ‘I love Dad ‘or’ I love you ‘.

Trac Thuy Mieu and Dai Nghia are two MCs who sympathize with Jun Pham’s situations.

Expressing sympathy, MC Dai Nghia said that for family love as well as love, we must learn and sympathize with each other to be able to put love in. Sometimes a generation gap or being a man makes it difficult for father and son to sit down and talk emotionally like a mother and a child. Therefore, it takes practice to understand and love family members.

Talking more about his father, Jun Pham revealed that, although strict, he is extremely resourceful, loving his children. In addition to knowing how to repair household items when things are broken, he is always ready to go to the kitchen to cook delicious dishes for his wife and children. This caused Trac Thuy Mieu to exclaim: “Cha Jun is a rare case, a very civilized person who loves his wife like that”.

Until he matured and achieved certain success, he understood that what his father worried about was absolutely correct. And during that time there was an unforgettable memory Jun Pham: “The first time Jun took his salary and sent it all to his father. At that time, my father was very emotional, hugging Jun and crying always made me goosebumps and remember that feeling, I was so happy. Although I now make a lot more than 2 million, I still feel that 2 million is the biggest I brought to my family. From that moment on, Dad felt he was growing up. Dad and Jun accept to sit down and talk and share with each other ”.

Starbucks switched to paper straws, but other tools still used plastic.

The trend of using paper straws

The campaign to stop using plastic straws has created a global craze over the past few years, with many reputable brands and a large number of consumers turning to paper straws.

In Vietnam, a number of major beverage brands have also responded to the messages of environmental protection, limiting the use of plastic waste, and encouraging the replacement of biodegradable and recyclable materials.

Pioneering brands can be mentioned as coffee shop chain The Coffee House, Trung Nguyen Legend Café, Starbucks Coffee … replacing plastic straws, plastic bags, disposable plastic spoons with bio straws, bags Bio, bio-spoon is completely biodegradable. Gong Cha and Phuc Long tea chains have replaced plastic straws with straws made from bagasse and paper.

But are paper straws really the same eco-friendly alternatives as the brands claim? Chung Shan-shan, scientific director of environmental management and public health at Hong Kong Baptist University, doesn’t think so.

According to SCMP, the main argument for using paper straws instead of plastic straws is that paper is biodegradable. That is, paper straws can decompose naturally and do not float in the ocean and then be swallowed by fish or turtles. However, environmental protection is not simply about swapping plastic for paper.

Although paper straws will decompose into smaller pieces, they are still capable of being swallowed by small animals. Furthermore, the term “biodegradation” can be misleading.

“The Hong Kong Environmental Protection Agency’s Biodegradability Test Standard considers the degree of degradation of different materials by keeping them at a constant temperature of 56 to 60 degrees Celsius for 180 days. . If the carbon content of that material is reduced by 60% then it can be considered biodegradable. So in fact, the so-called biodegradable materials can last longer than 180 days and even then, they do not disappear completely “, this expert emphasized.

“Although paper is biodegradable, it will not decompose even after a very long time if it contains too much pulp. You can find newspapers in landfills, where even after 10 or 20 years, the words on it can still be read.

Also, the garbage in the cities is ultimately in landfills, not in other spaces. The waste that decomposes in landfills still releases toxic methane gas into the atmosphere.

Paper straws spoil the taste of drinks

Paper straws easily spoil the taste of drinks.

Since China introduced restrictions on the use of plastic materials last year, non-biodegradable single-use plastic straws have begun to be phased out from the country’s food industry in late 2020. and the eco-friendly straws that are used nationwide.

Experts say, thanks to the trend of protecting the environment, paper straws and similar products are bringing huge revenue for manufacturing companies. According to a report by Huaan Securities Co Ltd, the size of the paper straw market in this country could reach 28 billion yuan (4.33 billion USD) by 2025.

But in addition to the controversy over the degradability, the paper straws have also complained about the quality, as well as affecting the taste of the drink. Most of the time, biological straws are worn out when left in water for a long time. They mix paper flavors into drinks, causing discomfort for diners.

Huang Xinyi, a 30-year-old worker in Beijing, told China.org: “Paper straws taste like paper or cardboard and cannot be soaked in drinks for long. That is why, I need to drink all the drinks right after I buy it.

No matter how environmentally friendly the paper straw is, it is having trouble being accepted by the consumer. “Paper straws also have an impact on the environment. On the one hand, they consume a large amount of wood resources, on the other hand, they also pollute the production process. More efforts are needed for research and further work.” developing other alternatives, “said expert Lin Boqiang from the Energy Policy Research Institute at Xiamen University, China.

When complaints related to paper straws became a popular topic, Chinese netizens made comments about alternative straws such as biodegradable plastic, metal straws …

Environmental protection half-hearted

Highland Coffee is the brand that propagates the most about environmental protection but still uses plastic cups and plastic straws.

While major beverage brands in Vietnam such as Gong Cha, Phuc Long, The Coffee House, Trung Nguyen Legend Café, Starbucks Coffee … are replacing straws, mugs, bags with environmentally friendly materials. Responding to customers’ requirements as well as environmental responsibility, there are still opinions that this is just a half-hearted change, stopping at the level of “cutting”, not giving up altogether.

Some companies only change straws, but still use plastic cups, others are the opposite. Or even the most controversial recently is Highlands Coffee, when shouting out loud environmental campaigns on media channels but doing it in a way unlike anyone else.

This chain of drinks uses the highly reputed beverage handle section: “Biodegradable, eco-friendly handle”. However, in addition to the handle, the other things are still plastic cups, plastic spoons, even using a plastic straw, not using a paper straw.

The online community said that the changes and calls of the above brands are still only polished and “colored”, instead of serious implementation for the environment, as required by consumers.

It is said that firms can not completely replace plastic utensils for the purpose of maximizing profits. To replace the whole process and equipment, it will take a lot of time and cost.

Regarding the trend of moving from plastic to paper straws, Chung assessed that people want to reduce the use of plastic products but do not want to sacrifice convenience. Even though they are paper straws, they are still disposable waste.

“Unless you get rid of disposable items in natural places with a lot of wildlife, swapping plastic straws for paper straws won’t make any difference in the city,” Chung added.

The only guaranteed way to make a difference to the environment, says the expert, is that people stop using disposable straws.

“Even if we create products using the most eco-friendly materials, if they are still single-use products, the Earth’s environment will still be affected.” said.

This expert suggests that users can drink it directly or use a chopstick or spoon to eat topping in a cup.

In conclusion, it doesn’t make much sense to switch to environmental materials unless we use reusable items.
