Grant Project Number: 2R01AI110964-06

“Aim 1. Characterize the diversity and distribution of high spillover-risk SARSr-CoVs in bats in southern China. We will use phylogeographic and viral discovery curve analyses to target additional bat sample collection and molecular CoV screening to fill in gaps in our previous sampling and fully characterize natural SARSr-CoV diversity in southern China. We will sequence receptor binding domains (spike proteins) to identify viruses with the highest potential for spillover which we will include in our experimental investigations (Aim 3). Aim 2. Community, and clinic-based syndromic, surveillance to capture SARSr-CoV spillover, routes of exposure and potential public health consequences. We will conduct biological-behavioral surveillance in high-risk populations, with known bat contact, in community and clinical settings to 1) identify risk factors for serological and PCR evidence of bat SARSr-CoVs; & 2) assess possible health effects of SARSr-CoVs infection in people. We will analyze bat-CoV serology against human-wildlife contact and exposure data to quantify risk factors and health impacts of SARSr-CoV spillover. Aim 3. In vitro and in vivo characterization of SARSr-CoV spillover risk, coupled with spatial and phylogenetic analyses to identify the regions and viruses of public health concern. We will use S protein sequence data, infectious clone technology, in vitro and in vivo infection experiments and analysis of receptor binding to test the hypothesis that % divergence thresholds in S protein sequences predict spillover potential.”

Color me shocked, but that’s the funding proposal and there’s nothing in there even approaching whatever you’re talking about. But hey, maybe you’re referring to the rejected DARPA grant proposal leaked by DRASTIC:

“THE PROPOSAL PLANNED TO INTRODUCE “KEY RBD RESIDUES” INTO LOW RISK STRAINS TO TEST PATHOGENICITY IN HUMAN AIRWAY-CELLS”

Wowie, looks like we have a hit! Rather than reading their spin though, I went and found the REJECTED grant proposal:

“We will sequence spike proteins, reverse engineer them to conduct binding assays, and insert them into bat SARSr-CoV backbones (these use bat-SARSr-CoV backbones, not SARS-CoV, and are exempt from dual-use and gain or function concerns)”

If you’re not aware, these backbones are common lab vectors which aren’t pathogenic themselves, made from different viruses. Their sequences are significantly different than either SARS-CoV or SARS-CoV-2. So, chimeric receptor/backbone pairs are used to assess viral entry into humanized cells more so than virulence. You may disagree with whether or not that’s still too dangerous of a method, but it’s a moot point here because 1. The backbones proposed here are completely different than COVID, so it can’t be the same viral agent and 2. This is a REJECTED PROPOSAL. None of this was actually done and it’s fantasy to pretend it is.

Next claim: aerosolized droplet for vaccines:

“We will complement [broad scale immune boosting with bat interferon] by coupling agonist treatments with SARSr-CoV recombinant spike proteins to boost pre-existing adaptive immune response in adult bats… we will incorporate [recombinant spike proteins] into nano particles or raccoon pox virus vectors for delivery to bats”

They’re not proposing aerosolizing whole droplets with competent SARS-CoV in them you moron, they’re basically saying “hey, you know those nasal sprays we use for the flu every year? Let’s give that to bats”.

Ooh, my favorite. No scientist with integrity says that the genome wasn’t manipulated.

You’re gonna have to tell that to the couple hundred scientists who have been studying this for a while:

“There is no logical reason why an engineered virus would utilize such a suboptimal furin cleavage site, which would entail such an un- usual and needlessly complex feat of genetic engineering. The only previous studies of artificial insertion of a furin cleavage site at the S1/S2 boundary in the SARS-CoV spike protein uti- lized an optimal ‘‘RRSRR’’ sequence in pseudotype systems (Belouzard et al., 2009; Follis et al., 2006). Further, there is no ev- idence of prior research at the WIV involving the artificial insertion of complete furin cleavage sites into coronaviruses.”

There really isn’t any evidence of manipulation at all. The backbone isn’t a standard lab construct. The cleavage site could have arisen from recombination. In the spirit of good science, I would never rule anything out, but the evidence very much supports a natural origin. Lab leak from a sample? Maybe, but that’s different than genetic engineering. For that you need stronger evidence. The strongest bit of evidence we have is the stonewalling from WIV and China, which is certainly suspicious. But, it’s unfortunately incidental and that isn’t good enough to jump to conclusions.

Try actually reading the text of these proposals before reading someone else’s spin on it.

The original grant was to the EcoHealth Alliance, which then subcontracted the Wuhan institute to collect wild samples from bats. In other words, the whole point of the research was to try and catalogue viruses that existed in the wild with pandemic potential.

It’s not coincidence that lab samples there or in other facilities exist that are close in sequence to viruses later identified in humans. That was, in fact, the goddamn point of surveying bat coronaviruses: to identify those with spillover potential. And it’s absolutely possible one of these collected samples was mishandled and leaked from the lab. After all, lab leaked viral outbreaks happen almost every other year, and there were already safety concerns at this particular site published long before the pandemic.

But what you and every other mouthbreathing idiot is trying to say is that Fauci, a director of the NIAID at the time, personally directed gain of function research to engineer new viruses to infect humans and then that virus escaped. Which, speaking as a molecular biologist myself, is laughably backwards.

[-] justdoit@lemm.ee 75 points 9 months ago

No self-respecting scientist concluded that either a natural origin or a lab leak were the definitive cause of the pandemic. This is clear if you actually read scientific literature. It’s why phrases akin to “the most supported hypothesis is X” or “the Y theory is unlikely without more supporting evidence” are used. Both hypotheses were and are still possible explanations.

It’s people who get their scientific info from sources like the Telegraph that keep jumping to conclusions. Or people who don’t understand what a section leader at the NIH does, how research grants work, or what gain of function research is. You know, like yourself.

It’s a red flag when I’m making new friends too.

It just screams “I don’t read up on any viewpoints presented to me”

Just a very small correction- as with all biology, natural selection will drive a virus to replicate more effectively, that’s it. This does NOT mean a virus will automatically become less lethal over time. That’s an older hypothesis that scientists found was not in line with observation.

The newer hypothesis is known as “virulence-transmission trade-off”. The oversimplification of the idea is that if a mutation increases both transmission and virulence, it will also tend to be selected for. COVID is inconsistent with both hypotheses in certain ways though, so really predicting its virulence in the short or long term has proven difficult.

Oh no thanks, with the release of Ahsoka I’m filled up on fantasy for a while

Can we take a moment to appreciate the very real possibility that the Soviet space program of the 50s would have been able to land a lunar probe better than the current Russian program?

(Obligatory /s, space is hard and shit goes wrong sometimes)

This is an obvious exaggeration, but I can’t help but feel like we’re witnessing a death match between American democracy and the Republican Party.

I’m talking YouTube channels with a few thousand views, streamers with single digit viewers, writers who only get a few reads on their submissions.

Since the fediverse is all about boosting connection to smaller voices, let’s share the love!

One point to keep in mind is that drama also brings engagement IN, not just out. When the drama subsides, the temporary boost in activity from new users or lurkers will go down too.

That being said, the percent decrease was always gonna be in the single digits. The average redditor was never gonna stick with a prolonged protest of a service that remains free to use.

I do not miss you, holy-fucking-shit man, but I imagine I’ll be seeing you again here soon anyway.

What Reddit-ism is gonna make its way here next?

Just got very lightly flamed by another user for making fun of crypto and was told that Lemmy and crypto have “the exact same advantages and disadvantages”. Now I disagree heavily there, since even if it shares some principles I’d argue that the scale of the problems change when you’re talking about a global finance system versus a social media platform filled with beans. But it did get me curious- how many of you are crypto supporters?

285

Can’t a corporation just enter the space whenever they want to? Can’t they start or even buy out larger instances? Even if Lemmy does take off, wouldn’t this inevitably happen anyway if the space gets popular enough?

[-] justdoit@lemm.ee 33 points 1 year ago

This isn’t easy to answer for a lot of reasons. People “leave Reddit” in a lot of ways. Some deleted their account. Some nuked all their comments but left the account up. Some just deleted the app. Some stopped using Reddit but will eventually return. Some JOINED Reddit specifically to watch the exodus drama. Some made bot accounts to fuck with the numbers for fun. And of course, some users joined without ever being aware there was drama at all. Looking at the change in the number of users alone won’t yield the answers.

Other useful metrics would be number of posts/comments contributed, and daily active user statistics. But again, engagement may have actually been driven upwards recently because drama is fun to be a part of and redditors are notorious keyboard warriors.

Growth of lemmy and other similar platforms is another metric to use, but that number is affected by the converse of all of the reasons I listed above as well: A lemmy account doesn’t mean they deleted Reddit. It doesn’t mean they’ll stay off it. Not to mention lemmy’s growth is likely inflated by people signing up for multiple instances due to slowdown.

tl;dr: No one is gonna have a good answer to this yet. If they say they do, it’s likely gonna be a pretty inaccurate estimate.

So considering there’s a substantial push to get away from places like Reddit and Twitter, as an outsider I’m wondering how the fediverse is going to actually provide solutions to some already bad problems within higher resource platforms:

ADMIN/MOD ABUSE: Redditors are no strangers to mods/admins nuking comments, astroturfing, signal boosting/silencing, and so on. Doesn’t that problem just become worse in a federated system? As an example, a subreddit mod may ban users for whatever reason, but a lemmy instance admin could drag all their communities into their own drama if they choose to defederate, no? Losing access to entire instances instead of just one community/subreddit based on a power-tripping admin seems a big flaw. Am I missing something?

REPOSTING/X-POSTING: Reddit was already just the same tweets posted to like forty different subreddits, recycled weekly. On lemmy, there are now a handful of instances that contain virtually the same communities too. The lemmy.world/c/memes and lemm.ee/c/memes communities will post virtually the same content. And that’s just one. Aren’t feeds going to be overrun by duplicate posts in /All?

PRIVACY: I have no clue about this… are there extra security or privacy issues with something like lemmy?

SERVER ISSUES: This kinda goes without saying, but a small instance will already struggle to host even their own local users as traffic increases. Communicating across more and more instances is going to be extremely taxing. Access issues/desyncs seem like they’ll be inevitable. Doesn’t a federated system have more trouble scaling up than a centralized one because of this? How could small independently run servers keep up with exponential processing costs? Won’t this just squeeze out smaller instances? Add this to issues when instances choose to defederate, and you have two competing incentives: spreading out users to keep server stress low, and centralizing users to keep local engagement high. Isn’t this kind of a big hurdle?

Sorry for the wall of text- excited about lemmy in general but really have no idea about whether these are issues.
