Today's @ScienceMagazine papers on the #OriginOfCovid are not game-changing - they largely say the same thing as the original preprints in February but in a much more subdued and chastised manner.

My take on it:

@ScienceMagazine I'm going back on break from twitter, but I have a manuscript on the evidence around a market/wildlife trade #OriginOfCovid that is under peer review.

I hope to be able to share a peer-reviewed form of it later this year #NeverGiveUp
@ScienceMagazine For people looking for a summary of the evidence on #OriginOfCovid I've written a medium post with 5-6min read time.

It explains the plausible origin scenarios and why investigators are having a hard time determining how the outbreak in Wuhan started.

@ScienceMagazine I've updated my critique of Worobey & Pekar papers to
1⃣ explain how ascertainment bias led to cases unlinked to the market clustering in its vicinity
2⃣ address the virus-positive cage sample
3⃣ point out flaws in their "2 strains 2 spillover" hypothesis

Peter Daszak, who partnered with the Wuhan lab that likely caused the pandemic and is being debarred by HHS, continues to chair @NASEM_Health's forum on microbial threats.

Daszak's forum is hosting @theNASEM workshop on the future emergence of pathogens.
nationalacademies.org/event/43921_01…
@NASEM_Health @theNASEM The event disclaimer and website make no mention of Daszak's involvement in this event or any conflicts of interest. Image
@NASEM_Health @theNASEM This echoes Daszak's behind-the-scenes coordination of the infamous letter in @TheLancet casting lab #OriginOfCovid as a conspiracy theory without disclosing his conflicts of interest.

In 2020, leading virologists deceived a @nytimes journalist, resulting in NYT dropping the lab leak hypothesis.

Years later, these virologists continue to deny their perfidy while attacking experts like @sigridbratlie who call out their deception.
telegraph.co.uk/us/news/2024/0…
@nytimes @sigridbratlie At the @USFHealth Covid meeting, natural #OriginOfCovid proponents exalted one of these virologists.

Thankfully @ewinsberg read out the slack messages of these virologists which completely contrasted with their public stance.
@nytimes @sigridbratlie @USFHealth @ewinsberg Some consider the lies of leading virologists as indirect evidence for a lab #OriginOfCovid e.g. see the end of this anonymous analysis on youtube.

Why are some smart virologists making so many claims they should know are false?

I gave a 15min talk on a likely laboratory #OriginOfCovid at @USFHealth's @HdxAcademy meeting on hotly debated Covid topics earlier this month. The exchange with natural origin proponents and Q&A are worth watching. The recording is available now: digitalcommons.usf.edu/usfcovid/2024/…
@USFHealth @HdxAcademy The meeting covered other topics including lockdowns, vaccines, and public health messaging. I left the meeting with my mind changed on one topic - a sign of high quality scientific exchanges on issues that remain unresolved.
@USFHealth @HdxAcademy Several talks recalled the panic in the early days of the pandemic, especially in hospitals overwhelmed by covid cases. In crisis, public health decisions & messaging were often developed in echo chambers and not based on science.

National Academy of Sciences president @Marcia4Science says "NAS stands ready, as it always has, to advise the incoming administration."

How does @theNASciences plan to advise the new gov on #OriginOfCovid and research that can start pandemics?
science.org/doi/10.1126/sc…
@Marcia4Science @theNASciences In Feb 2020, @theNASEM convened 3 of the most highly conflicted experts to advise the US gov on #OriginOfCovid

They were Peter Daszak & Ralph Baric who collaborated with the Wuhan lab, and Kristian Andersen who published Proximal Origin. nationalacademies.org/news/2020/02/n…
@Marcia4Science @theNASciences @theNASEM What reassurance do we have now that @theNASEM @theNASciences are capable of convening experts without glaring conflicts of interest to advise the incoming administration on scientific issues?

Accidentally swore and got bleeped on my live interview with On Point @MeghnaWBUR while discussing why lab #OriginOfCovid must be investigated and why scientists must not lie or obfuscate the truth for political reasons.
wbur.org/onpoint/2024/0…
@MeghnaWBUR Meghna did an excellent job putting the arguments of natural #OriginOfCovid proponents to me so I could refute them directly in the interview.

The scientific evidence does not support a double spillover of the virus at the Wuhan market.
@MeghnaWBUR Those who condemn platforming the lab #OriginOfCovid hypothesis refuse to participate in a joint interview with me.

They say it's because they do not want to legitimize a lab origin but I believe it's because their arguments cannot withstand informed scrutiny.

I respect Dr Fauci's decades of service in gov. Being in charge during a pandemic is no small challenge & no one can lead for so long without making mistakes. However, it needs to be said that Dr Fauci has not surrounded himself with wise & honest people regarding #OriginOfCovid
These are the virologists & experts he trusted on #OriginOfCovid

In their private messages in early 2020, they mocked other virologists for not being able to predict their own lab leaks & misled a @nytimes journalist asking about a potential lab origin.
These experts published an influential letter 'The Proximal Origin of SARS-CoV-2' that was used widely to shut down questions about a lab leak.

In private, they wrote that evidence against a lab leak was not strong and speculated on genetic engineering.
