Here is a compilation of a few “evidence” that is said to strengthen the belief of those who are passionate about the existence of UFOs and aliens: Unexplained stories about UFOs 1. Captain William Schaffner Incident, North Sea On September 9, 1970, Royal Air Force pilot William Schaffner was flying over the North Sea when he spotted a strange object in front of his plane, hovering over the water in the North Sea. He decided to investigate, but a few minutes later radio contact with Captain Schaffner’s plane was lost. Schaffner’s plane was later found on the seabed. However, the dome was closed and there was no trace of the pilot. No one knows what might have happened to the captain. (Photo: Marca) 2. The incident Tehran, Iran On September 19, 1976, Iranian military forces detected an unidentified flying object in the sky over the capital Tehran. When two Iranian air force jets approached the mysterious object, the pilots lost radio contact with the ground. When preparing to fire at the UFO, their weapon system also failed. Only after leaving the vicinity of the strange ship did they resume full control of their aircraft. 3. The Lights of Rendlesham Forest, England The Rendlesham Forest Incident is the name given to a series of scenes that occurred in 1980 following an alleged landing of an unidentified flying object in Rendlesham Forest. The British Ministry of Defense has never considered this event a threat to national security. Therefore, the incident was never formally investigated. 4. US Navy encounters UFOs The encounter occurred during a combat exercise conducted in the Pacific Ocean off the southern coast of California on November 14, 2004. (Photo: History) Pilots of six F/A-18 Super Hornets reported detecting “something” in mid-air, and on radars of US Navy ships and other fighters in the area also appeared. this flying object”. In 2014-2015, fighter pilots of the USS Theodore Roosevelt aircraft carrier strike force also reported recording sensors that detected unidentified aerial objects. Amazing images of UFOs In 2016, the US Intelligence Agency (CIA) released a number of photos of mysterious flying saucers that had appeared in the past that the agency had never made public before. The UFO photo was recorded by Stock in 1952 in New Jersey, USA. At about 4:30 p.m. on July 29, 1952, Mr. Stock was sitting in his yard with a friend when they saw a strange object appear in the sky. He ran into the house to get a camera and took 5 pictures of this UFO. The mysterious object flew at an altitude of about 60m, then accelerated and disappeared. The flying saucer was then described as possibly made of metal, solid and had a transparent dome-shaped upper part. Stock and friends say that the disc is blue or blue, makes no noise and is about 10 meters wide. The image was taken on October 20, 1960 in Minneapolis, Minnesota, USA Another image released by the CIA is a strange, large, glowing disc, believed to have been taken on October 20, 1960 in Minneapolis, Minnesota, USA. This image has never been confirmed to contain any content, but it is believed to be one of the first examples of so-called “stealth UFOs”, the term referring to flying saucers hiding in the clouds to avoid was discovered. Pentagon admits UFOs In May 2019, the Pentagon admitted it was investigating UFOs after naval pilots claimed to have recorded UFOs during training exercises in 2004 and 2015. The program to investigate and study threats from unidentified flying objects (UFOs) took place from 2008 to 2011 and cost up to 22 million USD of the US Department of Defense. This is the first time the Pentagon has acknowledged the existence of this program. (Photo: Defense) In 2020, the Pentagon officially released three short videos showing UFOs, previously released by a private company. The footage, titled “FLIR1”, “GIMBAL” and “GOFAST” was captured by a camera on a US military jet. The videos show what looks like an unidentified flying object moving very fast under the infrared camera. Two of the videos feature officers marveling at the speed of the unidentified flying object. One of them speculated that the object could be a drone. NASA discovers thousands of exoplanets NASA has confirmed the number of extrasolar planets (exoplanets) in the thousands, and we can expect that number to continue to grow as we improve the technology that spaceflight can travel. into other regions of space. (Photo: Insider) This opens up the meaning: There are thousands of known planets that have not been discovered for a long time; and several other planets waiting to be discovered that could be in potentially habitable environments. Existence of the Search Institute for Extraterrestrial Intelligence (SETI) The Search for Extraterrestrial Intelligence (SETI) Institute was founded by Carl Sagan and Jill Tarter, two American astronomers who believe there is more interplanetary life than we thought. (Photo: SETI Institute) SETI’s mission is to “discover, understand and explain the origin and nature of life in the universe, the evolution of intelligence.” The institute’s brilliant minds are working day and night to find ways to trace it. life and aliens in outer space. Another scientific organization searching for intelligent life in the universe actually exists on Earth. It’s proof of how seriously humans care about “aliens”.

Illustration. Sunlight is the source of ultraviolet rays (also known as ultraviolet rays – UV rays). This type of radiation is the cause of a lot of damage to the skin. The level of damage from UV rays depends on the intensity of the light, the length of exposure to the light, and whether the skin is protected. Without protection from the sun’s rays, just a few minutes of exposure a day over time will produce noticeable changes to the skin. Freckles, age spots, blood veins, rough skin, wrinkles, loss of collagen, keratinization are all caused by the sun and one thing is for sure, the sun can cause skin cancer. The basic mechanism of action is as follows: When sunlight affects areas of the skin, immediately, skin cells will react by increasing the production of Melanin – the pigment that determines skin color. The more melanin, the darker the skin. There are 3 types of ultraviolet rays: UVA, UVB and UVC. UVC rays have the highest carcinogenic potential, but are absorbed and reflected by the ozone layer, so they do not reach the ground. However, there are currently many places where the ozone layer is punctured or thinned, the risk from UVC is very great. 99% of sunscreens have no UVC protection. In the scope of this article we only talk about UVA and UVB. Sunscreen for oily skin Oily skin that suffers from a thick layer of cream on the face will be extremely sticky and uncomfortable, not to mention if the cream is inherently whiter than the skin, when it is mixed with oil and then unevenly colored, it is a disaster. You should choose sunscreens that contain the words “No Sebum” (non-greasy) or “Oil Free” (oil free) on the package, or sunscreens that are gel, water or spray to avoid causing irritation. skin. If you do not have acne problems or too sensitive skin, then chemical sunscreen with light texture and fast absorption is the right choice. Also, another note: if you want to choose sunscreen when swimming, it’s best to choose those that say “Water Resistant” or “Water Proof” on the package, with an SPF of 50 to 70. and index PA+++. These can last up to about 40 minutes to 1 hour and then you need to reapply for the best sun protection. Sensitive skin Sensitive skin is easily irritated in the sun and many chemical ingredients are in sunscreen, so say no to chemical sunscreens (sunscreen) but choose a more benign physical sunscreen (sunblock). with skin. Choose a product with a thin, light texture or a sunscreen that clearly states sensitive skin. Normal skin This is the most indulgent of all skin types, so you can use almost any sunscreen. However, in the summer, it is still advisable to give preference to light, cool products that do not cause mystery to the skin. Sunscreen for dry skin For dry skin, choose sunscreen products that contain moisturizers, to provide the necessary moisture, improve dryness and create a protective film to protect the skin from dehydration. In addition, sunscreens for dry skin should also incorporate a waterproof feature, ingredients containing antioxidants to enhance skin protection from the bad effects of ultraviolet rays and prevent skin irritation.

According to Mr. Cong, during more than 2 months of mining Chia, the actual amount of copper received back only stopped at 3 units. Currently, on the Huobi exchange, Chia is being valued at $820. This means that after 2 months and 3 billion of capital, he earned about 56 million VND. Fear of missing out on green Bitcoin The reason given by Mr. Cong is that although Chia saves electricity, it is difficult to compete with the super mines in China. Besides, the dramatic drop in the price of cryptocurrencies in the past week also increased the payback time of Chia mines. The hard drive is what determines the success or failure of Chia mining. “I invest a lot of money but I am quite vague about my income. The reason is that I fear that I will miss the opportunity to get rich like the way Bitcoin created 4 years ago. There were very few Bitcoin miners back then, I was one of the first. That’s why I have faith in Chia. But things don’t seem to be as I thought,” Cong said. According to Mr. Cong, his Chia mining system uses a 6TB HDD. Each of these hard drives costs 6.5 million VND. The number of hard drives in Mr. Cong’s mine is close to 300. Previously, the price of HDDs was only about 2-4 million VND. However, the wave of Chia mining has made the hard drive double in price. To cope with the huge write rates of Chia miners, many memory manufacturers have designed SSDs specifically for this purpose, like TeamGroup’s T-Create Expert model with a write limit of up to 12,000 TB. Amazon Web Services also recently opened a Chia mining service for the Chinese market. Hard drives increase in price, are in short supply but still have to buy more “In the game of chia mining, whoever has the most large capacity hard drives, that person has a higher chance of winning. And the winners at this point are the mining pools in China. They buy large quantities of hard drives at very high prices to gain an advantage in the market,” said Mr. Reply Zing , a representative of GearVN store confirmed the shortage of goods with large capacity drive models. However, this company’s customers, mainly individual users, have not been affected much. Hard drive prices have doubled since April because of the green Bitcoin craze. “GearVN’s customers are mainly end users and gamers, with a demand for hard drive capacity from 1 TB to 4 TB. In this segment, the price and supply are still stable,” a GearVN representative shared. This is also considered the biggest risk when participating in the “Green Bitcoin” market. According to experts, the difficulty of Chia mining is many times faster than Bitcoin. This means that mining systems must be invested with as many hard drives as possible. Previously, Bitcoin could be mined at individual scale because of the slow increase in difficulty. In the Chinese market, many traders have gathered thousands of hard drives to redistribute to Chia miners. According to ADATA, thanks to Chia, the number of SSDs sold by this company has increased 5 times in the past month. The shortage of goods makes many manufacturers of hard drives and SSDs prioritize serving the Chinese market. Order time in other markets is 2, 3 times longer. “In the past, every time a new order was placed, the waiting time was about 4-6 weeks. Now, the waiting time must increase to 8-10 weeks, high-capacity lines can sometimes be up to 13-15 weeks. Calculated, the standby time increased 2, 3 times, “said a representative of a distributor of the Seagate hard drive brand. Despite having an advantage in power consumption, Chia has a problem with mining materials, here is the hard drive. “I have to constantly buy hard drives while the price is getting more and more expensive. Without a hard drive, we wouldn’t have a place to store the strings of codes that can form a Chia,” said Cong. Uncertain future Chia was created by Bram Cohen, the “father” of the BitTorrent peer-to-peer file transfer protocol. The company behind this currency is Chia Network, backed by investor Naval Ravikant, some well-known companies such as Andreessen Horowitz or Cypherpunk Holdings. From May 3, this currency will be publicly traded and exchanged. According to the Business Insider , Split based on PoST (proof of space and time) consensus algorithm. In it, PoS (proof of space) describes an allocated hard drive space for blockchain block storage. In other words, the “miner” Chia will reserve a certain amount of memory space on the hard drive to store blockchains. Mining is very little, but participants have to constantly buy more hard drives in order to have space to store the blockchain. They will be awarded based on the ratio of memory cells that “miners” have to store compared to the entire network, as verified by a VDF server (aka Timelord). Chia Network, the representative company, said that this currency has good security, consumes less energy than coins using the PoW (proof of work) consensus algorithm. Unlike Bitcoin, Chia has no limit on the amount of coins mined on the blockchain. Instead, the number of diggers that can be mined will change continuously depending on demand. Chia Network, the company responsible for this currency will hold 21 million Chia in order to control price fluctuations, reducing the possibility of problems. Although the future of Chia is envisioned as ideal, the coin has only been traded on a number of crypto exchanges since early May with the token XCH. At first, the price per dong has more than doubled from $700 on May 4 to $1,600. However, facing the decline of the entire cryptocurrency market, Chia also suffered a price drop. Besides, too much hard drive also makes the Chia project away from the original “green” purpose of the founders. The owner of the net shop unplugs the machine, digs coins and waits for the translation to end Due to the impact of the Covid-19 epidemic, Mr. Nguyen Minh Quan (Thu Duc City) had to close the net shop, remove the graphics card to dig coins, earn extra income waiting for the reopening of the shop.

The Egyptian pyramids are a giant structure in the middle of the desert and can be seen from extraterrestrial satellites. Building these pyramids was certainly a huge task, so who did it? The pyramids could not have been built by Jewish slaves, as no archaeological remains that can be directly related to the Jews have been found in Egypt dating to 4,500 years ago, when the needles Giza pyramids were built, archaeological research has revealed. Also, the story told in the Hebrew Bible about the slavery of the Jews in Egypt refers to a city called “Ramesses.” A city called pi-Ramesses was founded during the 19th dynasty (circa 1295-1186 BC) and named after Ramesses II, who ruled 1279-1213 BC. This city was built after the pyramid construction period ended in Egypt. Furthermore, no archaeological evidence has been found of the lost city of Atlantis for any length of time, and many scholars believe the story to be fictitious. For aliens, this idea is said to be impossible. In fact, Egyptologists say, all the evidence suggests that the ancient Egyptians built the pyramids. However, how the pyramid builders lived, how they were rewarded and how they were treated is still a mystery that researchers are still investigating. The pyramids and the people who built them Egypt has over 100 ancient pyramids, but the most famous include the first-order pyramid, built during the reign of pharaoh Djoser (circa 2630-2611 BC) and the first real pyramid. was built during the rule of pharaoh Snefru (circa 2575-2551 BC). The Great Pyramid was built at Giza during the reigns of pharaoh Khufu (circa 2551-2528 BC), and two of his successors, Khafre (circa 2520-2494 BC) and Menkaure (c. 2490-2472 BC), there are also pyramids built at Giza. The pharaohs gradually stopped building pyramids during the New Kingdom (1550-1070 BC), choosing instead to be buried in the Valley of the Kings, about 483 km south of Giza. Over the past few decades, archaeologists have found new evidence that provides clues as to who the pyramid builders were and how they lived. Surviving records, including papyri manuscripts discovered in 2013 at Wadi al-Jarf on Egypt’s Red Sea coast, suggest that large groups of workers helped bring the materials to Giza. The papyri found at Wadi al-Jarf tells of a group of 200 men led by an inspector named Merer. This group of workers moved the stones by boat along the banks of the Nile, 18km from the Great Pyramid at Tura, where the stones were used to build the pyramid’s outer layer. Egyptologists have previously theorized that the pyramid builders were largely done by seasonal farmers, times of the year when there was little agricultural work to do. The papyri detailing the pyramid’s history is still in the process of being deciphered and analyzed, but the results indicate that the group led by Merer did more than help build the pyramid. These workers appear to have traveled through much of Egypt, possibly as far as the Sinai desert, carrying out many of the construction projects and tasks assigned to them. This raises the question of whether they are part of a permanent professional force, rather than a group of seasonal agricultural workers who will return to their fields. Pyramid builder treatment? According to Pierre Tallet, a professor of Egyptology at the University of Paris-Sorbonne in France, who is deciphering papyri manuscripts and co-leader of the team that found them, the workers were given a diet that included scrubs. is, vegetables, poultry and meat. In addition to a healthy diet, the papyri manuscript describes members of the working group regularly receiving textiles, which could have been seen as a reward at the time. In addition, officials in senior positions involved in the construction of the pyramids may have received land grants, said Mark Lehner, director of the Association for Ancient Egyptian Studies (AERA), a Massachusetts-based research institute. Historical records show that there were times in Egyptian history when officials were granted land. However, it is not known whether the land-granted officials were involved in the construction of the pyramid. Lehner’s team was excavating a town in Giza that was inhabited and frequented by several workers who were building the Menkaure pyramids. So far, archaeologists have found evidence that the ancient inhabitants of this town once baked large quantities of bread, slaughtered thousands of animals and brewed large quantities of beer. Based on animal bones found at the site, and considering the nutritional needs of workers, archaeologists estimate that about 1,800 kilograms of animals, including cattle, sheep and goats, were slaughtered on average. average daily, to provide food for workers. The remains of the workers were buried in the tombs near the pyramid, showing that the workers had healed their bones. This shows that they have access to medical care that is available at the time. The rich diet of the pyramid builders, combined with evidence of medical care and receiving textiles… has led Egyptologists to generally agree that workers did not must be slaves. However, this does not mean that all workers have equal accommodation. AERA excavations show that some of the more senior officials lived in large houses and had the best cuts of meat. In contrast, Lehner suspects, lower-level workers may have slept in simple houses or “rested” at the pyramids themselves.

A few days ago, the account of the magazine W Han released a series of photos of Rosé (BLACKPINK) inside the May issue with a quote about an exclusive interview Saint Laurent’s creative director Anthony Bacarello and woman idol . The interview with Anthony Bacarello reads: “ Rosé is the future girl of Saint Laurent, the way she lives, the way she leads fashion and the way she presents herself in public is amazing. ” Many people believe that based on what Saint Laurent’s Creative Director said, Rosé is not currently the official brand ambassador of the company, but in the future, this position will definitely not “slip”. out of the female’s hand idol . When asked about Anthony Bacarello, Rosé also said: “ If I were a good muse to him then great, it would be good if he could get a lot of inspiration from me. ” According to Rosé, she is one of Anthony Bacarello’s muses, and she is doing well in this role. Saint Laurent has also never officially announced that Rosé is the brand ambassador of the brand in the mass media. But from what Creative Director Anthony Bacarello said and the huge impact Rosé has had on its product sales over the past few years, Saint Laurent cannot find another qualified artist. brand ambassador over Rosé.

He added that the Abel Prize (considered the Nobel Prize for Mathematics) in 2021 was awarded to a pioneer in the field Zero Knowledge Proof – Scientist László Lovász (Mathematical Institute Alfréd Rényi and University of Eötvös Loránd in Budapest, Hungary), and Avi Wigderson (Institute for Advanced Study in Princeton, USA). The puzzle is as follows: Isla works in an office with 100 employees. One day, she discovered that her favorite paperclip was stolen by someone else. She identifies the suspicious object. Annabel, her colleague, said she was also suspicious of a person. Isla wants to know if she and Annabel are suspicious of the same person, but the two don’t want the other to know who they are doubting, in case they suspect different subjects. Isla thinks over and over how she and Annabel can check if they suspect the same person without revealing the information they find suspicious to the other party. The question is whether Isla and Annabel can find a way to reconcile their thoughts without letting the other know who they are doubting? This method should ensure that, after comparison, Isla knows whether she and Annabel are suspicious of the same person. Second, they need to make sure the other person doesn’t know they are distrusting. This verification is part of the protocol Zero-knowledge . At first glance, Alex Bellos judged that this was a puzzle without a solution. For example, Isla cannot say “The person I suspect was late for work on Monday” because it revealed some information about the other person. He also came up with a third party two-man solution, Dan, a good friend they trust a lot. Then, Isla and Annabel numbered the office staff from 1 to 100. Next, they write the number to replace the name of the suspect on a piece of paper and give it to Dan. If Dan confirms the two numbers are the same, they suspect the same person and vice versa. However, this solution is not perfect as no one can guarantee Dan from disclosing his number to the other person. Everything depends on the level of trustworthiness of the third party. Therefore, it cannot guarantee the non-disclosure of information as the quiz requires. Nearly 200 people participated in discussing Alex Bellos’s riddle and proposing measures to verify that Isla and Annabel were suspicious of the same person. Then, the author Alex Bellos together gave 3 relatively suitable methods. Can you take any measures to ensure the request of the assignment or not, ie Isla and Annabel know if they are suspicious of the same person and do not disclose information about the suspect to the other person? Readers who have difficult problems that need to be answered or want to share good calculations can send them to the newsroom at giaoduc@zing.vn.

Ancient Mayan civilization simulated on a 3D model. The laser survey showed that in a mountainous region north of Yucatán, called Puuc, the Mayans built remarkable structures, including artificial reservoirs, more than 1,200 stoves, several fields. ladder to cultivate … Research lead William Ringle, professor emeritus of anthropology at Davidson University in North Carolina, USA said: “It looks like this is a very prosperous area because we have all the stone houses. build. ” Furthermore, the Mayans of Puuc built four major towns dating from the Middle Ages (700 BC to 450 BC) and population centers dating from 600 to 750 AD, during the Late Antiquity period. dictionary. While these structures were recorded, laser data analysis revealed that these Puuc communities had distinct city layouts that were not seen in other Maya regions. Researchers have known of the ancient Mayan settlements of Puuc since the 1840s, but there has never been a comprehensive survey of the area so far. By calculating with laser light, a software can create a detailed 3D topographic map of ancient Mayan civilization. Researchers spent about 20 years doing basic research in the Puuc region. Analysis of the lidar maps, which encompass about 237 square kilometers, revealed 7,900 housing quarters, including on the hills, indicating that the Puuc area with a large population was concentrated mainly on the Different communities, with a few in the hinterland of Puuc. Many of these residential structures still have stone veins marking different rooms – each house has about 2-3 rooms. These details suggest that Puuc may be one of the most densely populated areas in the Maya Lowlands, an area that includes parts of modern-day Mexico, Guatemala and Belize. Despite the densely populated, it seems that the people in Puuc mainly live in peace; the communities are quite close together – usually between 5 and 10 km, but there is no evidence of any defensive structure. “There are images of warriors on some of the sculptures, but it’s not to the point where people stop themselves from the neighbors,” the researchers said. Water reservoirs A densely populated area needs a lot of water, but Puuc, like the rest of Yucatan, is mostly on limestone, a porous rock. Since there was no water or river or lake, people had to find other ways to get it. Puuc is located on a hilly and raised area, making it above groundwater level. To solve this problem, the Mayans built “chultunes”, or tanks, that were lined with mortar to collect rainwater. The Mayans also built “aguadas”, or reservoirs, with long drainage channels. Lidar’s survey revealed that some of these channels were several hundred meters long. Terraces The lidar survey also revealed evidence of an intensive and widespread rock-producing industry, consisting of quarries and 1,232 circular stoves, potentially used to sinter sandstone so that produce lime, or calcium oxide. This lime is probably used as a construction mortar and to help soften corn. “When people down there cook corn, they usually soak it in lime the night before to soften it a bit, and then they will grind it,” says Ringle. Therefore, lime is an essential commodity, even at the household level. ” The number of stoves was a surprising revelation, Ringle added. They are everywhere. And that shows that it’s a sizable industry in Puuc. Other research has shown that these stoves can be operated using very little firewood. “It tells us that people probably had the raw materials pretty close at hand, even though they didn’t burn the entire forest,” Ringle said. The lidar image also showed the first clear evidence of the ladder at Puuc, actually all north of Yucatan. Although the area has hundreds of hills, only 8 hills are terraced fields for cultivation. This shows that this practice is not popular in Puuc. The ancient Maya civilization existed for more than 2,500 years, before the people mysteriously abandoned their city. There are many theories that explain why this happens. Stories are told that the Mayans mismanaged their landscape and this led to their own destruction. This new study is contrary evidence. The study was published online April 28 in the journal PLOS One.

Recently, Duong Yen appeared in a commercial event. She wears a luxurious, elegant dress, with a very radiant and fresh charisma. But netizen Still think that Duong Yen’s appearance is poor. The first is the curly hair that makes Duong Yen a few years old. The actress’s face, which is already very small, is covered by thick and long hair, making her look even thinner. But the most shocking are the legs of Duong Yen. In the photo released by the studio, Duong Yen has quite small legs but is still smooth, straight, and exactly the type of legs desired by every girl. But in the fan’s photo that has not been edited, Duong Yen has very long legs that are so thin that they are bony, and the knees are protruding. Also because the legs are too thin, they are no longer slim as before. From any angle, the legs of Duong Yen also make the audience suffer because they are as tiny as a baby’s feet. Many people do not understand how Duong Yen can be healthy enough to work when his physique is so slender. Duong Yen is one of the actresses with the longest legs in C-Biz, 1m72 high and the legs are up to 1m15, helping her to have the desired body proportions. However, the actress is quite thin, making her legs no longer toned and healthy. Everyone thinks that if Duong Yen adds a few more pounds to her fleshy body, her legs will be much better.

Variant B.117 was first spotted in London and neighboring Ken County. Photo: AP Researchers in Shanghai have traced the original evolutionary trail of variant B.117, which has caused a new wave of COVID-19 infections in several countries, according to the Morning Post. But they found no trace of it in virus samples collected from people around the world. However, when they expanded their search to animals, they discovered some of the original B.117 forms in dogs, including one taken in the US last July. Such precursor variants include most or all of the original variant B117 in the Canidae breed, and they may re-infect humans after a period of rapid mutation. ”, Professor Chen Luonan and colleagues at the National Key Cell Biology Laboratory, wrote in an article published April 16. The appearance of the B117 variant has puzzled researchers. After being isolated from two patients in Kent County, southeast England, and London in September 2020, it quickly became the dominant strain of SARS-CoV-2 in the UK and many other countries, at a rapid rate. spreads faster than previous strains. Some experts believe this variant may emerge from local communities under pressure from antiviral drugs used during the pandemic. According to a popular theory, it suddenly appeared in Britain and then spread to other parts of the world. But variant B.117 has nine distinct mutations, rarely found in previous human strains – according to Professor Chen et al. These mutations do not occur in adjacent genes, but spread across the entire genome of the virus. The likelihood of all of these mutations appearing at once is extremely low. The Shanghai team believes that the above nine mutations are produced one after the other. Their model suggests that the variant may have originated outside the UK and received mutations on a non-human host. Dogs are the most suspect, followed by weasels or cats. However, Qu Liandong, professor of virology at the Harbin Veterinary Research Institute, who was not involved in the study, said more solid evidence is needed to support this theory. According to Qu, the strains found in dogs are not quite the same as the first strains identified in British patients. And although the number of genome sequences that researchers have globally reached in the hundreds of thousands, it is still small compared to the total number of patients there. If the dog is to be a host, “we’ll have a big problem.” Photo: AP Professor Qu, who studies infectious diseases in humans and animals, said that if pets like dogs become hosts, “we will have a big problem”. “Nearly all of our measures against the pandemic so far have taken into account people only. If the animal was involved, it would completely change the ‘game’, he said. When bird flu breaks out on a chicken farm, all chickens there must be destroyed, according to standard worldwide practice. If the disease can infect humans, all susceptible animals – including healthy ones – must be disposed of in the affected area. Dogs are close companions for humans, but if they are proven capable of carrying or creating mutant variants of the Sars-CoV-2 virus, they can also be destroyed, Professor Qu said. An alternative solution is to vaccinate animals. “But we can’t give the dogs human vaccines. We may need to develop some completely new versions. We have had a hard time vaccinating humans. How can the program be extended to both dogs or other animals? ”- Professor Gu raised the problem. There is growing concern that the B.117 variant could make dogs very ill. Veterinarians near London noticed a sudden increase in pets – including dogs and cats – with myocarditis earlier this year, and many of these animals tested positive for variant B. 117 – according to a Reuters report in March 2021. Another problem is, humans and animals have different immune systems and it is often difficult for viruses to spread from one species to another. The SARS-CoV-2 virus is thought to have originated in bats, but it can take decades to adapt to humans. When and where it made the animal-to-human transition is still unclear. Professor Chen’s team said that variant B.117 has a unique evolutionary strategy of increasing infectivity, so it can spread more easily from host to host, but at the same time reducing the number of copies it makes in the host. The researchers believe that whether this strategy helps variant B.117 overcome the species gap requires further study.

Earth has been 4 billion years old since its birth in the universe. In the long history of the Earth, the stars, planets, satellites, asteroids in the universe along with the Earth have all had a fixed or uncertain mode of action. The formation of the Solar System, the Moon, asteroids crashing into the Earth, comets … prove that claim.

As the development of human civilization took shape on Earth, we began to explore the mysteries of the universe and our own planet.

Humans have discovered countless impact craters on Earth formed by the “falling stars” that once crashed into the Earth. These “falling stars” are then referred to as “meteorites / asteroids”, and the traces they leave on Earth are known as “meteorite craters” or impact craters.

It can be said that the crater is a symbol and evidence of the intersection of cosmic objects and the Earth. Not only that, some scientists who support the “exogenous” theory even believe that the water and energy necessary for life on Earth today are due to the impact of meteorites and comets.

Although this is not supported by strong evidence, the craters are still very valuable to scientists studying celestial celestial bodies. It is of great significance for the study of the formation and evolution of the Earth, the change in climate, the environment and animals in ancient times, the role of biological processes and mineralization.

Today, many meteorite holes have been discovered, through studying them, people have discovered many unknown secrets from ancient times as well as unique minerals created when Huge asteroid collided with the Earth.

THE LARGEST THIEN THIEN THE PLANET

According to the report of the Earth Impact Database released in 2016, worldwide there are about 190 impact craters detected so far. And the planet’s largest, oldest and most severely eroded asteroid crater is Vredefort Crater in South Africa.

The Vredefort asteroid crater is a crater that has existed on Earth for 2 billion years – it is the result of a meteor’s shock impact with the Earth at speeds right between 40,000 and 250,000 km / h. The diameter of the Vredefort Crater exceeds 300 km, making it the largest and oldest meteorite crater in the world (second after the Yarrabubba crater in Australia (2,229 billion years old), NASA updates for 2020.

The Vredefort meteorite hole in South Africa.

This huge meteorite hole is located in the Free State province, South Africa. Because the crater is so large, local people do not realize it is the “legacy” from the “meeting” of the Earth and meteorites. However, its enormous size has attracted scientists and geologists from all over the world.

In 2005, the United Nations decided to include the Vredefort impact pit on the list of World Heritage Sites in need of protection.

LOOK AT THE PAST – FORWARD TO THE FUTURE

Talking about the crater / meteorite hole, many people do not know the Chicxulub (Yucatán peninsula in Mexico), 150 km in diameter, occurred about 65 million years ago.

Many scientists believe that perhaps the extinction of a generation of dinosaurs on Earth at that time was related to the climate change due to the impact of this meteorite.

Likewise, as the world’s largest crater, the formation of the Vredefort Crater should have had a serious impact on Earth’s climate and biological evolution. We just haven’t figured out exactly what it has affected and how it affects it.

Before that, the United Nations formed a scientific research group, based in South Africa, and conducted scientific research in the Vredefort crater for seven years. In the end it was asserted that the meteorite’s destructive power plunged into Vredefort enough to change the climate and the structure of the African plate. Scientists are continuing to study the long-term effects from Vredefort’s earlier.

What is different from Vredefort’s other meteorite craters in the world is that it has grown from what should have been abandoned into a city complete with hundreds of thousands of inhabitants, and generations of people have been in This huge crater is like a peaceful paradise.

Scientists said, meteorites that plunged into the Earth may leave large “scars” for Earth on the bottom of the deep sea. Because the asteroid craters we’ve found so far are all above ground.

Due to the very large and deep seabed area, scientists currently do not have enough technology to conduct detailed investigations. Therefore, the impact crater on the sea floor remains an unsolved mystery in the scientific world. If you want to research, you must go through a long process of discovery by scientists, and this will also be the direction that scientists need to strive for in the future.
