"You may disagree with their unconventional approach, but the truth is that these people behave, to all intents and purposes, like a small scientific community: they search and analyze data, they share and discuss their findings and, more importantly, they make discoveries."
Timely piece by @emmecola on how a coalition of twitter users, several anonymous, have been at the front of investigating the origins and sample history of RaTG13 + connection to SARS-like cases among miners from a Yunnan mine full of bats in 2012. mygenomix.medium.com/the-origin-of-…
Their work and fringe (I say this positively) influence on scientists & journalists has led to measurable outcomes. Namely, this @Nature addendum, confirming that RaTG13=4991; was seq'ed in 2018, not post-covid; linked to severe respiratory cases in 2012.

I find it both encouraging & problematic that it is outsiders & non-experts - who are often indiscriminately denigrated as conspiracy theorists - that are making these insightful, key discoveries about SARS-CoV-2 lineage viruses & holding top journals and scientists accountable.
I have a very strong pro-science pro-expert stance (otherwise why would I still be a scientist?). I believe that the vast majority of the time, experts are on the right track and working together (or against each other) so that the research community & humanity advances steadily.
So I'm still hopeful that, as the pandemic is overcome worldwide, more established & trainee scientists will start considering and publicly discussing both the scientific and "detective" findings surrounding SARS-CoV-2-like viruses and what this means for the #originsofSARSCoV2
Regardless of how fiercely you disagree with someone, threatening or calling them conspiracy theorists before engaging on the facts is unconstructive & polarizing.

If we can destigmatize the discussion of plausible lab origins, it will deradicalize the theories being circulated.
@emmecola your article reminded me of @TheAtlantic MH370 story “engineers and scientists.. on the internet, called themselves the Independent Group.. collaborated so effectively that the Australians took their work into account.. formally thanking them.” theatlantic.com/magazine/archi…
The independent group of internet sleuths was also featured by the @SYSKPodcast MH370 episode - "they also agitated for more transparency" and even obtained raw data (~15:55 min mark onwards). iheart.com/podcast/105-st…

Are these the 8 other SARS viruses from the Mojiang mine? Where can the sequences and metadata be accessed?

The partial RdRp sequence for Ra7896 can be found here: ncbi.nlm.nih.gov/nuccore/MN3126…

Associated with this May 31 preprint, later in Nature Comm: biorxiv.org/content/10.110…
Latinne et al. (EcoHealth, WIV et al.) say "Our host datasets included.. 528 β-CoV sequences (273 new sequences, including 97 new SARSr-CoV sequences (Sarbecovirus) from 31 bat species"

Could be helpful to post the 97 SARSr-CoV sequences in one dataset.

@shingheizhan and I just submitted for peer review our rewritten pangolin CoV manuscript within a mini-review of what we currently know about RaTG13 and the chances of natural spillover in Wuhan. We are hopeful that it gets through this time and will be published in early 2021.
The story about the possible intermediate host and how SARS-CoV-2 spilled over into humans has changed so much over the past year. We were told in Jan that the virus came from wild animals sold at the market. And then in Feb that it was likely pangolins...
All of these trails have fizzled out... leaving no trace of an intermediate host, no clear evidence of natural spillover, while the closest virus relatives are from bats in Yunnan, a thousand miles away from Wuhan city.

Thread breaking down the newest peer-reviewed study suggesting that COVID was on the West Coast in mid December, 2019.
It's not impossible that SARS-CoV-2 arrived in Europe and the US in Dec 2019, but consider that out of 640 throat swabs from Wuhan patients w influenza-like illness, Oct 2019-Jan 2020, only (9) samples in January tested positive for SARS-CoV-2. nature.com/articles/s4156…
Even in the city where cases were detected in Nov 2019, even when only patients with influenza-like illness are considered (not random blood donors), the virus could only be detected in January 2020 patient samples.

Nothing really surprising in the new Wuhan leaked documents shared by CNN, but I find this sobering:

"The documents show health care officials had no comprehension as to the magnitude of the impending disaster."

cnn.com/2020/11/30/asi…
A month before, one of the first whistleblowers was made to sign a letter on Jan 3, 2020 confessing to spreading rumors and violating the law.
"In the future, doctors will be more afraid to issue early warnings when they find signs of infectious diseases." bbc.com/news/world-asi…
The day after Dr. Li signed the letter, a leading Chinese vaccine developer Sinopharm kicked into high gear manufacturing a covid vaccine on Jan 4; 2 weeks before China confirmed human-to-human transmission.

“With publication count highly valued, analysis may also be delayed as teams ‘salami slice’ the underlying results into multiple papers.” 🤣
Been in research for 12+ years and can say that the inability to reproduce a considerable amount of work published even in high IF journals has real costs - to scientists' careers, the research ecosystem, and taxpayers who are ultimately paying for the vast majority of research.
Research publishing can be compared to a game of bluff, where the biggest winners are not necessarily the most honest. But in research, there's no reward for calling someone's bluff, which can likely drag you through years of hell, stalling your own career.

Great article by @sciencecohen
"Not urgently needing the vaccines at home to fight a virus it has largely quashed, (China) is playing a global game.. using the vaccine to promote the diplomacy of foreign policy objectives."
sciencemag.org/news/2020/11/g…
In-depth discussion of China vs the West's vaccine approaches: which can induce broader immunity, is easier to manufacture and distribute, has the risk of antibody-dependent enhancement of covid, and, importantly, can be readily manufactured locally in other countries...
"crucially for China’s vaccine diplomacy, many.. countries have manufacturers that have produced inactivated virus vaccines for decades.. (those) that cannot access vaccines bankrolled by Warp Speed—especially those that hosted China’s.. trials—might have a more secure vaccine.."
