You are talking about a CCP government that intentionally killed 10s of millions of its own people over the years, and let infected people out of Wuhan fly all over the world. Do you honestly think they worry about diverting or misrepresenting funds?Infection_Ag11 said:B-1 83 said:You are genuinely clueless about the nature of Chinese and the Chinese Communist Party.Infection_Ag11 said:Quote:

Then you are forced to argue they should never be giving grants to anyone, anywhere, ever on the basis that someone might lie about the funding utilization and it slip through the cracks. And scientific innovation both here and globally suddenly takes a huge it.
I think it is you who doesn't understand how intertwined our economies and scientific endeavors are. At present, thousands and thousands of American and Chinese scientists operate in each other's countries or with each other's funding on numerous projects and this relationship has tremendously benefited your life in ways you likely wouldn't know about unless I told you. You use no less than 10 objects/products/services every day that are at least in part due to this relationship.

The double CGG spike protein insertion alone, and proximity to WIV (working with/for Peter Daszak) vs. the supposed bats with the disease precursor (over 500 miles away) are vastly less likely to have been the provenance.

They knew early on, this is not my opinion but the opinion of virologists.

In July, the NIH attempted to backtrack. It reinstated the grant but suspended its research activities until EcoHealth Alliance fulfilled seven conditions, some of which went beyond the nonprofit's purview and seemed to stray into tinfoil-hat territory. They included: providing information on the "apparent disappearance" of a Wuhan Institute of Virology researcher, who was rumored on social media to be patient zero, and explaining diminished cell phone traffic and roadblocks around the WIV in October 2019.
But conspiracy-minded conservatives weren't the only ones looking askance at Daszak. Ebright likened Daszak's model of researchbringing samples from a remote area to an urban one, then sequencing and growing viruses and attempting to genetically modify them to make them more virulentto "looking for a gas leak with a lighted match." Moreover, Ebright believed that Daszak's research had failed in its stated purpose of predicting and preventing pandemics through its global collaborations.
It soon emerged, based on emails obtained by a Freedom of Information group called U.S. Right to Know, that Daszak had not only signed but organized the influential Lancet statement, with the intention of concealing his role and creating the impression of scientific unanimity.
Under the subject line, "No need for you to sign the "Statement" Ralph!!," he wrote to two scientists, including UNC's Dr. Ralph Baric, who had collaborated with Shi Zhengli on the gain-of-function study that created a coronavirus capable of infecting human cells: "you, me and him should not sign this statement, so it has some distance from us and therefore doesn't work in a counterproductive way." Daszak added,
"We'll then put it out in a way that doesn't link it back to our collaboration so we maximize an independent voice."
Baric agreed, writing back, "Otherwise it looks self-serving and we lose impact."
Baric did not sign the statement. In the end, Daszak did. At least six other signers had either worked at, or had been funded by, EcoHealth Alliance. The statement ended with a declaration of objectivity: "We declare no competing interests."
Daszak mobilized so quickly for a reason, said Jamie Metzl: "If zoonosis was the origin, it was a validationof his life work. But if the pandemic started as part of a lab leak, it had the potential to do to virology what Three Mile Island and Chernobyl did to nuclear science." It could mire the field indefinitely in moratoriums and funding restrictions.

Professor Montagnier is well-known for his radical, and often controversial, views within the scientific community.
One molecular biologist at the national research centre Le Centre National de la Recherche Scientifique (CNRS), Alexis Verger, last week tweeted a "reminder" that the professor is known for being anti-vaccinations, pro-homeopathy, and believes that "water has memory".
He has also been known to attempt to "regenerate DNA sequences from pure water and digitized electromagnetic signals and send them by email", said Dr Verger.
Professor Montagnier caused controversy in the scientific community when, one year after winning the Nobel prize, he claimed that "a good immune system" was enough to protect people against AIDS.

While the analyses above suggest that SARS-CoV-2 may bind human ACE2 with high affinity, computational analyses predict that the interaction is not ideal7 and that the RBD sequence is different from those shown in SARS-CoV to be optimal for receptor binding7,11. Thus, the high-affinity binding of the SARS-CoV-2 spike protein to human ACE2 is most likely the result of natural selection on a human or human-like ACE2 that permits another optimal binding solution to arise. This is strong evidence that SARS-CoV-2 is not the product of purposeful manipulation.
Quote:
Although no animal coronavirus has been identified that is sufficiently similar to have served as the direct progenitor of SARS-CoV-2, the diversity of coronaviruses in bats and other species is massively undersampled. Mutations, insertions and deletions can occur near the S1S2 junction of coronaviruses22, which shows that the polybasic cleavage site can arise by a natural evolutionary process. For a precursor virus to acquire both the polybasic cleavage site and mutations in the spike protein suitable for binding to human ACE2, an animal host would probably have to have a high population density (to allow natural selection to proceed efficiently) and an ACE2-encoding gene that is similar to the human ortholog.
Quote:
Estimates of the timing of the most recent common ancestor of SARS-CoV-2 made with current sequence data point to emergence of the virus in late November 2019 to early December 201923, compatible with the earliest retrospectively confirmed cases24. Hence, this scenario presumes a period of unrecognized transmission in humans between the initial zoonotic event and the acquisition of the polybasic cleavage site. Sufficient opportunity could have arisen if there had been many prior zoonotic events that produced short chains of human-to-human transmission over an extended period. This is essentially the situation for MERS-CoV, for which all human cases are the result of repeated jumps of the virus from dromedary camels, producing single infections or short transmission chains that eventually resolve, with no adaptation to sustained transmission25.
Quote:
Basic research involving passage of bat SARS-CoV-like coronaviruses in cell culture and/or animal models has been ongoing for many years in biosafety level 2 laboratories across the world27, and there are documented instances of laboratory escapes of SARS-CoV28. We must therefore examine the possibility of an inadvertent laboratory release of SARS-CoV-2.
In theory, it is possible that SARS-CoV-2 acquired RBD mutations (Fig. 1a) during adaptation to passage in cell culture, as has been observed in studies of SARS-CoV11. The finding of SARS-CoV-like coronaviruses from pangolins with nearly identical RBDs, however, provides a much stronger and more parsimonious explanation of how SARS-CoV-2 acquired these via recombination or mutation19.
The acquisition of both the polybasic cleavage site and predicted O-linked glycans also argues against culture-based scenarios. New polybasic cleavage sites have been observed only after prolonged passage of low-pathogenicity avian influenza virus in vitro or in vivo17. Furthermore, a hypothetical generation of SARS-CoV-2 by cell culture or animal passage would have required prior isolation of a progenitor virus with very high genetic similarity, which has not been described. Subsequent generation of a polybasic cleavage site would have then required repeated passage in cell culture or animals with ACE2 receptors similar to those of humans, but such work has also not previously been described. Finally, the generation of the predicted O-linked glycans is also unlikely to have occurred due to cell-culture passage, as such features suggest the involvement of an immune system18.

I don't know whether this was lab generated or naturally generated, although I suspect it came from that lab. But I doubt it was deliberately released. I would think you'd want to deliberately release it away from a lab that's studying coronaviruses. Hell, I figure you'd want the point of origin to not even be in your own countryTAMUallen said:
The source of Covid is the lab China. Question is if it was deliberately released or if it was accidental.
So, we just have never found a coronavirus with this mutation (insertion), but it was probably just a natural insertion the virus somehow developed right next to WIV from a bat species no where near there, and a pangolin, though we never found the guilty pangolins either?Quote:
In the case of the gain-of-function supercharge, other sequences could have been spliced into this same site. Instead of a CGG-CGG (known as "double CGG") that tells the protein factory to make two arginine amino acids in a row, you'll obtain equal lethality by splicing any one of 35 of the other two-word combinations for double arginine. If the insertion takes place naturally, say through recombination, then one of those 35 other sequences is far more likely to appear; CGG is rarely used in the class of coronaviruses that can recombine with CoV-2.
In fact, in the entire class of coronaviruses that includes CoV-2, the CGG-CGG combination has never been found naturally. That means the common method of viruses picking up new skills, called recombination, cannot operate here. A virus simply cannot pick up a sequence from another virus if that sequence isn't present in any other virus.
Although the double CGG is suppressed naturally, the opposite is true in laboratory work. The insertion sequence of choice is the double CGG. That's because it is readily available and convenient, and scientists have a great deal of experience inserting it. An additional advantage of the double CGG sequence compared with the other 35 possible choices: It creates a useful beacon that permits the scientists to track the insertion in the laboratory.
Now the damning fact. It was this exact sequence that appears in CoV-2. Proponents of zoonotic origin must explain why the novel coronavirus, when it mutated or recombined, happened to pick its least favorite combination, the double CGG. Why did it replicate the choice the lab's gain-of-function researchers would have made?
Yes, it could have happened randomly, through mutations. But do you believe that? At the minimum, this factthat the coronavirus, with all its random possibilities, took the rare and unnatural combination used by human researchersimplies that the leading theory for the origin of the coronavirus must be laboratory escape.
When the lab's Shi Zhengli and colleagues published a paper in February 2020 with the virus's partial genome, they omitted any mention of the special sequence that supercharges the virus or the rare double CGG section. Yet the fingerprint is easily identified in the data that accompanied the paper. Was it omitted in the hope that nobody would notice this evidence of the gain-of-function origin?
