This coming so close after the announcement by DeepMind that they're releasing the data on hundreds of thousands of protein folding structures has me with a growing knot in my stomach.

As generous and useful on a human-scale an announcement as that was, my first thought was how it could be abused. So too prion research.

Who'd've thunk that muscle bulk could be so scary? (!)

Kinda a morbid question but could you just sever the finger moments after the prick? Or would the blood pump so fast that the prion(s) is already in your body.

My housemate is an organic chemist and from a past conversation apparently there is a cautionary paper regarding a grad student who lost a hand due to delayed amputation of a finger after similarly being jabbed with some nasty chemical. Can’t find the paper unfortunately.

In this case I guess the message targets people in other cities than the doomed one. "This could happen to your city too".

you'd still have to wait a decade after the first attack to make threats on the second city.

I think reading about prions is the scary part, no need to wait for the deaths.

I remember hearing people arguing that the Covid lab leak hypothesis was implausible because of stringent safety measures.

I really don't want to go too far down the rabbit hole but IIRC some of the concern was due to a lack of stringent safety measures in a lab / similar labs.

I've always thought a _very_ effective strategy would be to get a crop-duster and spray a prion-contaminated mist over a major city, basically contaminating every public surface in a large area I'm also not sure how you would begin to clean up afterwards - do you remove the surface of everything in your city? To those saying bio-terrorism is ineffective or would not kill a lot of people in any appreciable time-scale,…

It's not really effective because it takes years to manifest symptoms of prion disease. Terrorism usually has a message attached to it, and "you're gonna start dying in 10 years" is not conducive to messaging.

living with knowing that i probably have 10 yrs before die in a gruesom neurodegeneration, knowing that if i interact much with our world that maybe i spread this to others, seriously terrifying, depressing, would induce misery.

"Terror" is the point of "terrorism". It's in the word.

Terror only propagates through mass media. Mass media is the issue.

Given that an attack of this sort would be propagated through mass media, then the claim that the attack would be ineffective is wrong.

Scary. I think and airborne human transmissible prion disease that kill in a few years is the kind of event that can bring our society back to prehistoric living in just a few decades. Hope it never happens.

I find prions unbelievably scary too. What reassures me is that they've had about 3 billion years to wipe out life on earth and haven't done it yet. Which means there must be some natural limits on their spread we don't know about yet.

Because we have had many population isolated. Indians never got black plague because Europeans isolated, but got smallpox when Europeans show up. Syphilis was deadly until making of penicilin, probably came back with Europeans from Indians. If whole world is connected then disease maybe can go through whole population.

From Wikipedia [1]: « Prions are misfolded proteins with the ability to transmit their misfolded shape onto normal variants of the same protein. They characterize several atal and transmissible neuro degenerative diseases in humans and many other animals. It is not known what causes the normal protein to misfold, but the abnormal three-dimensional structure is suspected of conferring infectious properties, collapsing…

The mediation HCG is processed from pregnant women’s urine and has been shown to potentially contain prions. I took it for years. Yay.

The sad thing is there’s a recombinant version that would be safe, but it also costs thousands of dollars.

Makes complete sense that there was resistance until a viable mechanism was proposed. Otherwise it just sounds like voodoo.

No, because the underlying data demonstrated that there was a statistically significant death effect occurring, with a wide range of evidence implicating prions, before there was a mechanism. You shouldn't require a plausible mechanism to trust your experiments (seen this a hundred times, like in RNA enzymes, heart of the ribosome, various dna-is-the-heritable-agent experimetns).

Yes you should: because all you have otherwise is a death rate that could be caused by any number of things. Biological organisms die all the time for all sorts of reasons: there's a difference between showing a series of factors lead to an death rate, and proposing the specific mechanism by which that happens and it's important.

That light behaves like a wave did not summarily prove there was an aether through which it propagated, and not finding it up-ended physics.
