They were going to experiment with multiple backbones, experimenting with multiple variations of spikes, looking specifically to try novel types of furin cleavage sites.
There was no public reporting of what happened with this research. We don't know what they have because WIV database was taken offline. They claimed to have searched it, but what they claimed was the closest match in the database was not, in fact, as close as a sequence they had published. Given that demonstrable lie, there is no way to verify any claim about what sequences were or were not known and possibly involved in this research.
Furthermore the person who submitted the proposal was also the person who broke ethical standards to preemptively shut down all discussion of a human release.
That isn't to take away from the possibility of a natural spillover. The facts that you say about that are facts. But accidental release is also possible. And the lack of transparency from those who are most likely to have made the mistake heightens suspicions, it does not lessen them.
It is research that "sounds like" what happened with the SARS-CoV-2 zoonotic spillover, but that isn't a strange coincidence. They were researching the thing they were worried about happening, and then it happened. Their research proposals naturally rhyme with what actually occurred because they had studied and understood the problem enough to guess more or less accurately what the process would be. There are still massive gaps in between this proposal and SARS-CoV-2 that you could fly a plane through.
The investigation will continue and those missing items you mention just might turn up since it appears from the leak that there are might be a significant number of unpublished sequences at WIV and EHA, etc.
If science is unsatisfied by what is found, actual scientists will move on and look elsewhere. This leak evidence is compatible with the man origin suspicions however.
"The grant proposal very specifically is concerned with using the WIV1 and SHC014 backbones, nothing related to SARS-CoV-2." The counterargument is "Well, they could have altered the proposal when they pursued funding elsewhere." The takeaway is that it is not likely this specific proposal was funded elsewhere, leading to SARS-CoV-2.
"If they actually carried out the research in this grant proposal you don't get from there to SARS-CoV-2, those are all SARS-1-like." I do not personally know how to evaluate the accuracy of this claim, but if true, it resonates with the first claim: this proposal funded elsewhere would not lead to SARS-CoV-2.
The argument claims about it being hard/expensive I think are less compelling, as there is a lead time of several years with experts in field performing research. A more compelling version of this argument would look like (completely making up numbers): "On average, it takes 4.5 years to develop the first samples of a novel virus using a selected backbone, CRISPR technology, and gain-of-function culturing. Therefore, even if this research was funded in 2018 we would not expect it to have led to SARS-CoV-2". I'm not saying that argument is accurate at all, just saying it's more specific than "it's difficult".
The argument claims about the evidence being missing I think isn't going to be motivating for a person who has a reasonable expectation that secret research is done and does not have trust in government transparency (either US, China, or otherwise). I'm not making a point here that evidence isn't needed (far from it, evidence IS needed). I'm evaluating from a polemic perspective what kinds of claims and arguments are useful for advancing the conversation with someone who holding a dissonant viewpoint.
Thank you by the way for making specific claims that can be fact checked such as the two referenced at the top of this comment.
It isn't as simple as altering the proposal. You're speculating a very large and hidden process using sequences that were kept perfectly secret and have not been leaked, with virus backbones that would take considerable effort to create but which were never shared publicly (and kept perfectly secret before SARS-CoV-2 happened before there was any need for perfect secrecy). We have this leaked information from 2018 about the proposal with the WIV1/SHC014 backbones which leaked because it was not kept with perfect secrecy. Yet they managed to do all that work in perfect secrecy without any leaks. That is the hallmark of a conspiracy theory. It requires a bit of a time machine because Daszak would have to have known in 2018 to tighten up his "OpSec" in response to the pandemic that hadn't happened yet and leaks that hadn't yet occurred.
Things are also getting worse for the lab leak theory on other fronts, I just stumbled across this a few minutes ago:
https://www.nature.com/articles/d41586-021-02519-1
If there's multiple lineages from multiple zoonotic spillover events that makes the lab leak theory a poor fit and will require a lot more mental gymnastics.
That sounds like a very tenuous line of reasoning to me. Almost like saying "We know that Mr. A proposed shooting Mr. B, so let's reconsider that Mr C. may have stabbed Mr. D."
Also, I'm not sure why the lab leak hypothesis is suddenly trickier. They had all sorts of samples.
Labeling this all as "mental gymnastics" as in the article, or "a dagger in the heart of the lab leak hypothesis" is just the sort of motivated analysis confirmatory bias that caused all this in the first place. I'm not sure how arguing that SARS-CoV-2 involved two spillover events with crossover from multiple species is less mental gymnastics than "a lab had multiple samples".
Honestly I'd like to see more dispassionate discussion of this. That Nature piece is shameful.
At some level I don't care if it was a lab leak or not but I wish there wasn't this level of motivation behind both sides.
In any event, the grant proposal should raise a lot of red flags regardless. What bothers me often is this implied assumption that if the lab leak hypothesis is false, everything else is fine. It's all fine that a plausible biosecurity failure scenario was ridiculed, that major research groups clearly lied about and tried to cover up conflicts of interest, that we can trust these (GoF) lines of research are safe, that we can just trust the authority figures to not cause another pandemic, etc. etc. etc.
It's like seeing smoke billowing out of a building and refusing to accept that there's a fire until you see the flames. Very convenient that your standard of evidence surpasses anything we can possibly obtain after the CCP scrubbed everything.
I would also argue that in the age of factory farming it is not so clear if more human-animal contact happens in rural areas or in big population centers. SARS was eventually traced back to palm civets which are farmed animals. In this industry wild animals, many of which are susceptible to SARS-like coronaviruses, are being bred in large numbers. To me this sounds like a perfect breeding ground for the viruses as well.
Better than TV.
Also, factory farming is far safer than all other forms of farming. If the outbreak was unrelated to WIV and centered in Wuhan, wet-markets and exotic animal markets are the likely culprit.
But nobody is alleging that they did all the work in perfect secrecy. Clearly we know about a lot of the work: you'd use the same equipment, location, and so forth. Only a few things are left that need to be secret; namely, the origin of the viral sequences that preceded SARS-CoV-2. And if those were present in the wild it seems not entirely surprising that WIV could have simply obtained them.
Furthermore, it is not really that surprising that research which potentially develops weapons of mass destruction is kept secret, pandemic or no. Whether it caused the pandemic or not, people are still generally concerned that this kind of thing was occurring.
I have to say though, the flagged reply was thoroughly entertaining. Thank you sir or ma’am for the high praise; I aim to please.
But maybe some things just haven't leaked yet? Or were kept secret by others even more skilled at secrecy & misdirection than Daszak?
But, this nature piece is really problematic. When removing likely sequencing errors, the independent "spillover events" appear to fit perfectly into a single phylogeny with each node separated by a single mutation. And the A clade descends cleanly from the B clade. There are not enough mutations between them to support a complex explanation like multiple spillovers. This is linked but not explained properly by the nature piece https://virological.org/t/evidence-against-the-veracity-of-s...
Why? The wet markets in Wuhan were sterilized and emptied (meaning that the animals inside were removed, killed, and their carcasses disposed of) at the very start of the outbreak - several days before anyone had definitive evidence that SARS-CoV-2 could be transmitted by person to person contact.
I'm sure that the Chinese government would love to have definitive evidence that SARS-CoV-2 is zoonotic, but that evidence likely went up in smoke (January 1st, 2020) weeks before anyone realized that COVID-19 would turn into a legitimate pandemic (January 23rd, 2020).
The stuff you cite is circumstantial at best. Yes, given the seriousness of covid i would like someone to investigate it, but i would hardly call it billowing smoke.
> Very convenient that your standard of evidence surpasses anything we can possibly obtain after the CCP scrubbed everything.
Is that really relavent? Say CCP would in theory destroy evidence if such a situation arised. That's not an argument that says it is china's fault, its just an argument that we might not ever know. Its not like the people arguing that it was natural aren't using lack of chinese whistleblower as the evidence for naturalness.
At the very least i'd like evidence that suggests there is a higher probability that it was a chinese experiment than a natural occurance. Occam's razor and all. Arguing that it might be impossible to know what happened, increases uncertainty, but doesn't affect the relative probabilities.
But that doesn't invalidate the animal transfer hypothesis. Because that isn't how science works -- or even just how KNOWLEDGE works. No one[1] operates under perfect certainty; we collect stronger or weaker evidence for various possibilities.
This grant application doesn't "prove" that SARS-CoV-2 was leaked from a lab. But nothing "proves" it wasn't. The existence of this grant application is evidence supporting the lab leak hypothesis, demonstrating conclusively that someone in the world was thinking, prior to the pandemic, about performing modifications to coronaviruses similar to what we have observed in the virus.
[1] Except mathematicians: https://xkcd.com/263/
I don't think that a lab leak is implausible, but your statement that the small pointers "cease being coincidences" because they fit a narrative imparts far, far too much certainty to the lab leak theory.
The internet doesn't handle subtlety well, so just to spell it out...
If we admit things are coincidences then they can't be added up to get evidence. Lots of coincidences isn't evidence. The point is these things aren't coincidences. If a new coronavirus breaks out next door to a lab studying coronaviruses, then the lab is a possible source of the virus and the proximity is evidence. It is weak evidence and still unlikely, but evidence nonetheless.
However, when the lab is very close and the closest known bat virus (RaTG13) is a very long way away as is the case for SARS-CoV-2 then that is starting to get quite murky as evidence goes. It would be much easier for RaTG13 to travel the rather large distance from its natural location to Wuhan in a freezer/test tube than in a bat.
This is why there has been a lot of attention on certain animals, such as raccoon dogs and minks. It turns out that a lot of the early infections linked to the various Wuhan markets were from shop owners and employees who either sold or were in close contact a small number of animal species. It also turns out that these animals can be infected by SARS-CoV-2. See https://ncrc.jhsph.edu/research/animal-sales-from-wuhan-wet-....
The issue is that (as far as I'm aware) there's no immediate evidence that SARS-CoV-2 jumped to humans from any of these animals, only that there was an (again, as far as I'm aware) unknown intermediary species. However, because the animals at the wet market were disposed of, there's no way to definitively link SARS-CoV-2 to them.
Every single denial comment around here hinges on this confusion in terms and then tries to stick the "no proof" meaning to all the evidence, instead of bringing whatever evidence there is that it was a natural strain evolution or debating the various points.
Funny how instead a meta analysis of the discussion show one side piling up evidences while the other insists in trying to convince people that no proof equals no evidence.
If it’s conceivable that gain of function research can release a virus that kills millions, then the burden of proof is with the researchers to prove that they’re safe and this didn’t happen.
(a) It was successfully created in the lab using gain of function research they were developing
(b) It was accidentally or purposefully cultured naturally from one of the many strains they had collected from the field
(c) A researcher, assistant, or contractor was infected in the field as they were doing field work
Option (c) is particularly compelling because it doesn't require much additional complexity beyond the "official explanation". It still maintains that the origin of Covid-19 was a zoonotic spillover event, but points to the research as the direct cause of that event. And it's not necessarily the case that if the virus was in the bat population already that it necessarily would have spread. Rural populations might become briefly infected with a pandemic-level virus, but the spread is naturally quarantined since they have little contact with major metropolitan areas.
In other words, your argument is like saying occam's razor concludes that fire extinguishers start fires because they are always found in the vicinity of fires.
Also I think many on this thread greatly underestimate the adaptive and evolutionary capabilities of nature. Having done some wet lab myself, I'm impressed at the ability of nature to do lateral gene transfer, and also it's damn hard to make any experiments work. Plus there are multiple layers of safety and containment around any lab experiment. Movies make engineering look like AI robots in labs and biology experiments that work on the first try, and people who say lab near outbreak must implicate the lab have probably spent more time watching movies about outbreaks than trying to engineer organisms themselves. Having spent a lot of time trying and failing to engineer organisms, occam's razor screams to me that the most likely explanation is natural evolution.
The real lab of concern are the hundreds of millions of people living in close contact with animal reservoirs, performing millions of competitive, uncontrolled evolution experiments daily, with single hosts sometimes simultaneously infected by multiple viruses, thus facilitating lateral gene transfer... and this continues to be the status quo. If you can accept that MERS and SARS CoV-1 are naturally evolved, then occam's razor would indicate that SARS CoV-2 is just one point in a series, and yet another coronavirus outbreak is likely to emerge in the next decade or so, from a dense urban area near animal reservoirs.
Distracting ourselves by fantasizing that only humans could be so devious to create such a virus makes us miss a very important opportunity to try and prevent the next outbreak through careful monitoring and research.
So, if you believe that we should have fire departments and fire extinguishers near ignition sources then, maybe we should have /more/ labs like Wuhan's in high risk areas, not less. And we'd want to encourage more cross border cooperation, not antagonize it, because viruses don't give a damn about your politics.
It's concerning that threads like this, on a forum as ostensibly pro-science as HN, are pushing ourselves further away from science and transparency...
The closest relative to this virus (it's not even that close, just 95% similarity) was found in a bat cave hundreds of miles away. They flew it in Wuhan and made experiments on it (this is all documented, not some crazy theory). Something tells me it's more likely to escape from the lab right there, rather than somehow infect people for hundreds of miles undetected. Your analogy is wrong, the lab is not really a fire extinguisher, because a fire extinguisher cannot cause fires on it's own! Lab leaks happen all the time https://en.wikipedia.org/wiki/List_of_laboratory_biosecurity...
A better analogy is: a nuclear scientist works with heavy metals at a lab (far away from home), suddenly his family gets radiation poisoning. I wonder if it was the scientist that made a mistake, or should we focus all our search for natural radiation sources in the family's house? Sure, it's always a possibility, but what is it more likely? Also, you should at least acknowledge that the person is working with radiation and investigate that possibility thoroughly.
Those lab safety measure were criticized by the US state department https://www.washingtonpost.com/opinions/2020/04/14/state-dep...
> And we'd want to encourage more cross border cooperation, not antagonize it, because viruses don't give a damn about your politics.
The Chinese took the virus database offline 2 months before the official outbreak...what a coincidence. And what a cooperation effort. Renaming the closest relative virus to hide it's trail. And a lot more.
Yeah, we need more cooperation, and China needs to do it first. They created this mess, the least they can do is cooperate rather than hinder investigations. We need better lab security and better protocols worldwide.
Applying Occam, I’m going to bet that the origins of the virus will turn out to be entirely zoonotic or that someone got infected doing fieldwork rather than the lab engineering claims.
It doesn't seem neccesary for a chinese lab to be involved, and the only evidence so far (afaik) is that it exists and was studying something similar. Meanwhile there exists (albeit definitely not ironclad) evidence that china wasn't involved.
If there is no evidence beyond circumstantial evidence that china had a lab near by, and there is a pretty much equally reasonable explanation that the event happened by chance, than i think occam's razor favours the one with less entities involved.
I'm not saying that china isn't involved. I'm saying that we basically have no idea and the argument that china did it is no more strong than the alternative. On the balance i find the natural explanation more compelling, but ultimately we have no idea. I also think there may be some cognitive biases going on - covid 19 has hurt, and we want scapegoat to blame. If it was natural, than we have only ourselves to blame for being underprepared. If china did it, we convinently have someone to hate.
How many major cities are there? hundreds. How many with a research center experimenting on coronavirus? (1 china, 2 in the USA) Just in China there are more than 100 cities with 1 millions people. Odds are 99+% that it has something to do with the research center. A very generous take would be that it has 1% chance of being unrelated.
If you take the other hypotheses, it goes like this: some bat coronavirus -> jumps to an unnamed animal -> jumps to a human. There is an unknown entity in this equation, which is the third party animal. This is necessary for the theory to work.
If you make me chose between a theory that has all the elements and one that might or might not find a mythical animal in the future...I think Occam's razor favors the one with all known elements. Otherwise, ad-absurdum, you can win any argument stating it's Occam's razor: you just introduce a single magic black box which can substitute any number of entities.
I am not doing this to blame China. I blame China for the opacity of the response, which at times seemed like they didn't care what happens with everyone else. I can blame China regardless of how this virus appeared. I also blame our top scientists, which covered their asses instead of coming out with everything they know and work for the greater good.
What I do want is better bio-labs safety protocols, something that can be monitor by third party inspectors, say from UN, just like we have for nuclear facilities. Lab leaks happen, it's not a Chinese thing: https://en.wikipedia.org/wiki/List_of_laboratory_biosecurity...
There seems to be an extraordinary amount of CYA here.
