One recent study reports the discovery of MERS-like viruses that use the ACE2 receptor like some SARS-like viruses.

Pre-covid, I would've thought it was neat.

Post-covid, all I can think of is that some scientist out there might try to make a hybrid of MERS- and SARS-like CoVs.
As a scientist, you really hope that -all- other scientists will have learnt from this pandemic not to try crazy **** that could potentially generate a pandemic pathogen or bring one from nature into urban centers.

But academia is like the Wild West.
Don't forget, in 2018/2019, scientists unintentionally created chimeric SARS-like viruses with enhanced pathogenicity in humanized mice and intentionally did more of the same work with human pathogen MERS, in a city of 11 million + international flights.
theintercept.com/2021/10/21/vir…
The above work was proposed to NIH who did not tell the scientists to cease and desist.

In Sep 2021, the grant holding organization, EcoHealth Alliance denied to reporters that the chimeric MERS experiments had been done despite submitting data on this to the NIH in Aug 2021.
Once you come to the realization that there's little regulation and little awareness of what scientists are doing with dangerous or novel pathogens around the world, you realize that a lab-based pandemic could be one scientist's bad day or accident away from happening.

If there was any science behind the rapid change of mind regarding a potential/likely lab #OriginOfCovid among the Proximal Origin authors, please share it with the world.

What was the evidence that emerged between Feb 2-4, 2020, that persuaded you SARS-CoV-2 was 100% natural?
The scientists implicated in this #OriginOfCovid drama can easily demonstrate the scientific process if there was any.

They should also amend Proximal Origin so all contributions are acknowledged. Why obscure the leadership provided by scientific leaders?
If people are worried that emails are getting taken out of context, you're welcome to peruse them yourselves:

I sometimes get the question "Aren't you afraid pushing for an investigation of a lab #OriginOfCovid will fuel dangerous conspiracy theories?"

I think scientists who appear to have conspired to suppress an investigation into a lab origin are the ones fueling conspiracy theories.
Do these highly redacted emails inspire public trust in science?
Does finding out that top scientific leaders in the US and UK planned to put their own members into the World Health Organization #OriginOfCovid group and put pressure on them inspire public trust in science?

The @WHO 2021 #OriginOfCovid study was not scientific. We don't need a repeat.

"Chinese counterpart eventually agreed to discuss the lab-leak theory in the report “on the condition we didn’t recommend any specific studies to further that hypothesis.”"

@WHO Troublingly, 5 out of 10 @WHO-convened international members of the 2021 team that signed off on the unscientific report is on the new SAGO team.

Countries cannot expect the @WHO SAGO effort to be a credible and thorough investigation of the #OriginOfCovid

Each country that cares about not having a pandemic happen again in the near future should initiate their own investigations free of competing interests.

Many people ask, what is the direct evidence for a lab #OriginOfCovid

If anyone had produced direct evidence of a lab or a natural origin, do you think we'd still be arguing about it 2 years later?

We need an investigation because we need to search for this direct evidence.
What can be said is that a natural #OriginOfCovid has been investigated much more thoroughly than a lab origin, at least publicly.

And the 2-year search for an intermediate host or original animal source of SARS-CoV-2 has found not a shred of direct evidence for a market origin.
.@TheLancet @richardhorton1 writes: "Proponents of a laboratory leak have so far provided no evidence to undermine this [Huanan market origin] explanation."

He might be unaware that even pro-natural origin investigators have failed to find evidence...

Because when everything you've done is above board, your legally FOIA'ed emails are massively redacted and the lead author of the Proximal Origin letter suddenly had ~5,000 of his tweets "auto-delete".
thetimes.co.uk/article/spectr…
And when you're not trying to cover up anything, you need to confer with the unacknowledged contributors to the paper as to how to explain the origin of Proximal Origin to journalists.
And when you're following the science, you need to stack the @WHO #OriginOfCovid group with your friends and put pressure on the group.

Although a formal #OriginOfCovid investigation has yet to happen, it's good to reflect that scientific progress has been made.

1 year ago, experts were comparing me to QAnon and calling a lab accident, concealed to hide incompetence, a conspiracy theory.

The hypothesis that SARS-CoV-2 might have been genetically engineered was breathlessly compared to the US insurrection.

Afaik there has yet to be any evidence that SARS-CoV-2 was not genetically engineered...
On the other hand, we saw a deluge of documents released in late 2021 pointing to gain of function research + a 2018 roadmap for inserting novel cleavage sites into novel SARS-like viruses (this genetic engineering could've produced SARS-CoV-2). theintercept.com/2021/09/23/cor…
