Since the outbreak of the COVID-19 pneumonia epidemic, some US politicians have begun to concoct the COVID-19 virus "laboratory leak theory". Even after the Biden administration took office, in order to increase the pressure on China, it not only frequently broke the epidemic The source points to China, and even the World Health Organization has become the target of being threatened by the United States. However, paper can't hold the fire after all! Regarding the tracing of the COVID-19 virus, new clues have come from the United States. According to a report by Guangming.com on August 23, according to a recent article published on the American academic journal website, Ralph Barrick, known as the "coronavirus hunter," has been working on researching, transforming and manufacturing the coronavirus for decades. Virus "technology". Barrick and the two research institutions engaged in research on high-risk viruses and coronaviruses in Fort Detrick, the US Army Medical Research Institute of Infectious Diseases, and the "Comprehensive Research Facility" under the National Institute of Allergy and Infectious Diseases, are both Have close ties.
Barrick, 67, is a professor of virology and infectious disease at the University of North Carolina at Chapel Hill. He has been in the field of coronavirus for more than 30 years and has his own laboratory. According to the official website of the National Academy of Sciences, Barrick mainly studies three RNA viruses, including coronaviruses that cause severe respiratory infections. Statistics show that since 1983, Barrick has published more than 400 papers in his own name or as an instructor, including 268 papers on coronavirus.
According to the US "MIT Science and Technology Review" magazine, Barrick has mastered a technology that uses "reverse genetic technology" to transform and even "enhance" the coronavirus. With this technology, he can not only cultivate a living virus based on the gene fragments of the coronavirus, but also modify the gene of the coronavirus to create a new coronavirus.
According to the US "Journal of Virology" website, in 2002, Barrick's leadership team established the world's first reverse genetic system of murine hepatitis virus based on fragment assembly. Relying on this system, scientists can conduct research on viruses in vivo. By changing the genes or structure of the virus, they can understand the role of each gene in the interaction between the virus and the host. In 2008, Barrick and others published a paper in the Proceedings of the National Academy of Sciences, detailing the method of designing, synthesizing and activating a SARS-like coronavirus, and specifically verified that this artificial virus can not only infect mice Sickness can also invade human respiratory ciliary epithelial cells.
It is worth noting that Barrick has close ties with the two research institutions in Fort Detrick that are engaged in research on high-risk viruses and coronaviruses. A large number of scientific research papers show that Barrick has conducted many research collaborations involving coronaviruses with the US Army Institute of Infectious Diseases. Barrick's abundant coronavirus "resources" and the "technology" for transforming and manufacturing the coronavirus are widely used in Fort Detrick through these cooperation and contacts.
