Suggestion for scientists and science communicators/journalists:

When the available evidence to support/rule out a particular hypothesis is little to none, let's stop saying "there is no evidence for X" and instead say "we are still gathering evidence to know whether X is true".
Watching #InTheSameBreath @HBO documentary drove home the damage that can be caused by experts making statements like there is no evidence of human-to-human transmission or masks protecting against Covid etc.

Could have been avoided if experts said we're still looking into this.
Saying that there is "no evidence" for something implies that a search for evidence has been conducted and turned up nothing.

In many cases, investigators are still in the process of searching for evidence. A premature assertion of "no evidence" would mislead the public.
People are off to the races with extreme hypotheticals.

I think the phrase you're looking for is "the available evidence is inconsistent with (insert your extreme hypothesis here)".

For example, the available evidence is inconsistent with a #PopsicleOrigin of Covid-19.

I know people are exhausted by COVID-19, but I highly recommend "In the Same Breath", a superbly produced @HBO documentary by @wangnanfu revealing the scale of the outbreak in Wuhan, then New York & how difficult it was for people to share their stories.
hbo.com/movies/in-the-…
@HBO @wangnanfu One thing that surprised Wang (and me) was a case where a 31-year-old patient admitted to hospital in Nov 2019 was said to have caught Covid-19 in hospital and was ill through December, Jan, Feb, before passing in Mar 2020.

There is surely more to learn about the earliest cases.
Also painful to watch was the mirror reflection of the outbreaks in Wuhan and New York - healthcare workers were misinformed by the authorities about how the virus spreads, not given resources to protect themselves, and censured by their employers for "spreading rumors".

How can we determine whether scientific journals are opening their gates to #OriginOfCovid debate by publishing articles that aren't biased towards only a natural origin?

The public has embraced the debate, but I don't think our scientific journals have.

There have been some notable exceptions in top scientific journals, e.g., @PNASnews Nov 2020, David Relman: To stop the next pandemic, we need to unravel the origins of COVID-19
pnas.org/doi/10.1073/pn…
Bloom et al. @ScienceMagazine Investigate the origins of COVID-19

I did a mini thread in Feb on why I do not find the ENaC hypothesis compelling, particularly one that involves a UNC specialist telling a Wuhan scientist to use the furin cleavage site from ENaC in their SARS-like viruses.
It's possible a Wuhan scientist independently chanced upon the FCS in ENaC and thought it might be a good insertion for SARS-like viruses, but it's just as likely they saw other cleavage sites (RRAR) in novel viral sequences and used that as inspiration.
It would be more striking to me if the match including the entire FCS insertion "PRRA" or if the rest of the match "RSVAS" (5 out of 8 matching letters) didn't already exist in many of SARS2's close relatives.

I'm noticing a recent uptick in people tweeting about Covid-19 having been created in the US by collaborators of the Wuhan Institute of Virology.

Please think through this carefully. You're saying the Chinese have proof the US created this virus and unleashed it on Wuhan...
... and though the Chinese gov has been desperate to shift the #OriginOfCovid outside of China - desperate enough to inculcate its people with the idea that the virus can spread through frozen 🐟 and the 📬 - they refuse to use the proof that the virus was made in the US.
Your hypothesis is, despite possessing proof that the virus originated in a US lab, the Chinese state media engaged in a disinformation campaign last year that went nowhere... even making up a Swiss scientist to complain about the #OriginOfcovid inquiry.

Not sure @PeterHotez read the @PNAS letter carefully.

"SARS-CoV-2 is, to date, the only identified member of the subgenus sarbecovirus that contains an FCS, although these are present in other coronaviruses"
@PeterHotez @pnas "We do know that the insertion of such FCS sequences into SARS-like viruses was a specific goal of work proposed by the EHA-WIV-UNC partnership within a 2018 grant proposal (“DEFUSE”)"
@PeterHotez @pnas "We do not assert that laboratory manipulation was involved in the emergence of SARS-CoV-2, although it is apparent that it could have been. However, we do assert that there has been no independent and transparent scientific scrutiny to date..."

From the @TheLancet COVID-19 commission chair:

"EHA-WIV-UNC was involved in the collection of a large number of so-far undocumented SARS-like viruses.. manipulation within.. (BSL)-2.. raising concerns that an airborne virus might have infected a.. worker"

@TheLancet Hey @shingheizhan our peer-reviewed @MolBioEvol figure is cited in the letter!
@TheLancet There are 2 components to the Harrison & Sachs letter.

1. There are parties in the US that have repeatedly resisted sharing information relevant to #OriginOfCovid and they should be compelled to cooperate in a formal, ideally bipartisan, US-based investigation.
