Covid-19 does not have a credible natural ancestor: study | India News

LONDON: Amid calls for new research into the origins of Covid-19, a new study found that Chinese scientists created the virus in a laboratory in Wuhan and then tried to cover their tracks with reverse-engineered versions of the virus to do it. seems to have evolved naturally from bats.
The novel SARS-CoV-2 coronavirus does not have a “credible naturallancestor” and was created by Chinese scientists who were working on a ‘Gain of Function’ project in a Wuhan laboratory, the Daily Mail reported Sunday, citing a new article. research of British professor Angus Dalgleish and Norwegian scientist Dr. Birger Sorensen.

Covid-19 does not have a credible natural ancestor: study | India News

The new research claims that scientists took a natural coronavirus “backbone” found in Chinese cave bats and spliced ​​it with a new “beak,” turning it into the deadly and highly transmissible Covid-19.
The document also cites that the researchers found “unique fingerprints” on Covid-19 samples that they say could only have arisen from manipulation in a laboratory.
Authors Dalgleish and Sorensen wrote in their paper that they had prima facie evidence of retroengineering in China for a year, but were ignored by major academics and journals, DailyMail.com reported.
The study alleges “deliberate destruction, concealment or contamination of data” in Chinese laboratories and notes the silencing and disappearance of scientists in China who spoke about the activities.
The research, obtained by DailyMail.com, is expected to intensify the ongoing debate about China’s role in creating the virus that has claimed thousands of lives.
In the 22-page article to be published in the scientific journal Quarterly Review of Biophysics Discovery, Dalgleish and Sorensen reconstructed how Chinese scientists, some working with American universities, allegedly built the tools to create the coronavirus.
By the way, “gain-of-function” projects, which involve modifying natural viruses to make them more infectious, had been banned by former US President Barack Obama.
In an exclusive interview with DailyMail.com, Sorensen said that four amino acids in the peak are positively charged, causing the virus to firmly stick to negatively charged parts of a human, becoming more infectious.
Because these positively charged amino acids also cancel each other out, it was rare to find even three in a row in natural organisms, while four in a row is “extremely unlikely,” he said.
“The laws of physics mean that you can’t have four positively charged amino acids in a row. The only way to do it is if you make it artificially, ”Dalgleish told DailyMail.com.
“The implication of our historical reconstruction, we now postulate beyond reasonable doubt, of the intentionally manipulated chimeric virus SARS-CoV-2 makes it imperative to reconsider what types of gain-of-function experiments it is morally acceptable to undertake,” they wrote.
In the paper, the scientists wrote that a natural virus pandemic would be expected to gradually mutate and become infectious but less pathogenic, which did not happen in the case of Covid-19.
Dalgleish and Sorensen claimed that after the pandemic began, Chinese scientists took samples of the COVID-19 virus and “ retroactively engineered it ”, making it appear as if it had evolved naturally.
“We think retro-engineered viruses have been created. They changed the virus, then they tried to distinguish that it was in a sequence years ago, “Dalgleish told DailyMail.com.
The scientists also noted that Chinese scientists who wanted to share their knowledge have been unable to do so or have disappeared.
Sorensen said he believes the virus escaped from less secure areas of the institute, where he believes a Gain of Function investigation was conducted, DailyMail.com reported.
“We have seen laboratory leaks and we know it is happening. We also know from the reports we have seen that the coronavirus is being worked on in biosafety level 2 or 3 laboratories. If they get gain of function in such labs, what do you expect? ” he said.
In February 2020, Botao Xiao, a molecular biomechanics researcher at the South China University of Technology, published an article stating that “the killer coronavirus likely originated in a laboratory in Wuhan,” highlighting the safety concerns at the institute. . However, he withdrew the document weeks later after Chinese authorities denied any accident at the laboratory.
Dalgleish further told DailyMail.com that he believed China’s resistance to the theory that COVID-19 is a man-made escaped virus comes from scientists who fear the disclosure will shut down their field.
“This seems like a weak defense to protect the discipline so that this kind of genetic engineering is not interfered with. I don’t worry about it. Gain-of-function engineering should have been outlawed a long time ago,” he said.
Although former MI6 chief Sir Richard Dearlove publicly said that the scientists’ theory should be investigated, they said their research was dismissed by major scientific journals who insisted the virus jumped naturally from bats, DailyMail reported. .com.
However, leading academics, politicians, and the media have now begun to contemplate the possibility of Covid-19 escaping from the Wuhan Institute of Virology (WIV) in China, where experiments included manipulating viruses to increase their infectivity with in order to study its potential effects in humans.
US President Joe Biden said on May 26 that he had asked the US intelligence community to “redouble its efforts” to reach a conclusion on the origins of Covid-19 and report back to him within the 90s. days.
China’s state media rejected the idea that Covid-19 had originated there, saying it is “a conspiracy created by US intelligence agencies.”
A few days ago, an article was published in the Wall Street Journal that revealed that three researchers from the Wuhan Institute fell ill in November 2019 and had to be hospitalized. The report was based on previously undisclosed US intelligence. The researchers were admitted to the hospital a month before China reported the first case of Covid-19.
The revelation has sparked debate and raised questions about whether China was aware of the deadly virus long before it informed the world.
Recently, former New York Times science journalist Nicholas Wade published an article in the Bulletin of the Atomic Scientists arguing that the evidence is stronger than the virus leaked from a laboratory than the fact that it occurred naturally. .
In an elaborate report, Wade said that much of the Chinese virologists’ work on gain of function in coronaviruses was done in the BSL2 security level laboratory, which requires fairly minimal security precautions. The pandemic broke out in the Chinese city of Wuhan in December 2019. “For the laboratory escape scenario, the origin of the virus in Wuhan is a no-brainer.
Before that, an Australian newspaper revealed that Chinese scientists were thinking of biological weapons, envisioning a World War III scenario. The Australian newspaper Weekend cited a Chinese government document that discussed the weaponization of the SARS coronavirus.
DailyMail.com further reported that China had installed the first of five to seven Biolabs planned in Wuhan in 2017 for the purpose of studying the highest-risk pathogens, including Ebola viruses and SARS.
In March, the director general of the World Health Organization (WHO), Tedros Ghebreyesus, also called for more studies after the publication of an inconclusive report on the field visit of an international team to Wuhan to investigate the origins of Covid. -19, citing difficulties in accessing raw data.
