Recently, the U.S. Senate Health, Education, Labor and Pension Committee released an interim report. The report concluded based on the analysis of public information that the COVID-19 pandemic may be caused by research-related events. However, to prevent unnecessary storms, the report added that if new information released in the future is verified, the US Senate may change this assessment.
The most core content of this report issued by the U.S. Senate is the study that determines that the new coronavirus originated in the laboratory, but this report does not indicate which way it was done.
Previously, a team of scientists in Germany claimed that they had found evidence that the new coronavirus originated in the laboratory. Because they found a "fingerprint" in the genome of the new coronavirus, which is a pattern that recurs regularly in the viral genome.
After comparison, these scientists found that the recognition points of natural viruses are completely randomly distributed, and in artificial viruses, they always appear in specific patterns, and this pattern exists in the new coronavirus. From this, German scientists came to a preliminary conclusion that 99.9% of the new coronavirus is artificial, and more specifically an artificial replica of natural viruses.
The saying that the new coronavirus in the United States originated in the laboratory has started very early. In particular, The biological laboratory of Fort Detrick in the United States is widely questioned, and with the progress of the Russian-Ukrainian war, more and more evidence has disclosed the biological experimental activities carried out by the United States in Ukraine.
20 years ago, many remarks were discussing that the 21st century will be the century of biology , so many students were confused by this statement and jumped into the four major pits of biochemical ring materials.
But from the current perspective, it is still very likely that the 21st century is a century of biology. First of all, the relevant companies have made a lot of money in the past few years. And there is still great uncertainty about what will happen in the future.
Especially on the screen that was filled with World Cup news recently, on November 27, a quiet news made biology a focus of people's attention.
According to the British journal New Scientist, an international team of scientists successfully "resurrected" the prehistoric giant virus that had been frozen for 48,500 years. The report also warns that melted permafrost may bring a variety of prehistoric viruses, posing new threats to humans.
Although the report says it is "resurrection", it is more appropriate to use "resurrection". The team recovered seven viruses in the permafrost layer of Siberia , the youngest was frozen for 27,000 years, and the oldest was frozen for 48,500 years. This is by far the oldest virus to recover. Previously, the team's scientists had "resurrected" two other prehistoric giant viruses that were 30,000 years ago.
According to reports from Russia today, these viruses belong to Pandora virus, which is an megawavirus that can infect single-cell organisms such as amoeba . Studies have shown that these viruses can still infect living cells after spending tens of thousands of years in permafrost.
This virus was first found in amoebacterium in 2003. It is a pathogen of human amoebacterium dysentery. By the way, I would like to complain that there is a business model called Amoeba. I don’t know who gave it. Do you want to explain that using this model will cause diarrhea and slim belts?
At that time, scientists saw some spots in the amoeba protozoa. Because they grew very big, they thought it was a bacteria. Later, after genetic sequencing, they determined that this was a virus.
This virus has a huge genome, can encode more than 900 proteins, and can even participate in protein translation by itself, which is more omnipotent than modern viruses.
This time, the discovery means that as 1 global warming , the permafrost melts, which is likely to cause the spread of unknown viruses.
Plague has always been an important factor affecting human development. The resurrection of ancient viruses is also the goal that scientists have been studying.
1 The global influenza in 1918 caused about 25 million to 100 million deaths worldwide (the large data gap is mainly due to the different criteria for the identification of statistical caliber). Later scholars have been arguing about the caliber of this virus. Later, scientists successfully found samples of the Eskimos who died of influenza from the permafrost layer of in the Arctic Circle, thus finding the complete gene sequence of the influenza virus. But the viruses at that time had died and it was impossible to infect experimental animals. So scientists began to study how to revive the virus.
Finally in 2005, with the unremitting efforts of scientists, CDC approved the research application for the reconstruction of the live virus based on the 1918 influenza virus sequence, resurrecting the already disappeared virus in the laboratory.
has become the modern world of the global village, and international personnel exchanges frequently. What changes will this revived ancient virus bring to people's daily lives? We will wait and see.
