    I almost forgot there were ML models besides LLMs! [RFdiffusion](https://www.bakerlab.org/2023/07/11/diffusion-model-for-prot...), used for the protein discovery, is a model somewhat related to diffusion-based image generation. So much of the attention right now is about what LLMs can do with their coding, agentic, and research capabilities as they get more and more powerful and self-improving. It's fun to be reminded that ground-breaking things still can come from "your dad's neural networks."

    Also... just because I was checking through the results of the paper to see if it was actually an interesting result: "The SHRT binder provided complete protection (100%) to mice . . . . The LNG binder exhibited comparable efficacy, completely neutralizing α‐cobratoxin but not the non-target ScNtx"

      Yeah David Baker and co. are using a lot of diffusion models for their research! And yeah some of these mice results are very good, and hopefully they translate to a good degree to humans

    The "over 100,000 deaths" seems like a slight exaggeration, this paper bounds the estimate at 40,000-80,000: https://www.nature.com/articles/s41467-022-33627-9 Wikipedia's "Epidemiology of snakebites" had similar estimates.

    That's still a lot of people! But I was skeptical of 100,000, especially without a source.

    • Lol_arco 7 hours ago
      Yes you're right! It's very hard to estimate how many people die from snake bite, for a thousand reasons (under reporting, incomplete snake databases, etc). This meta analysis indeed puts the numbers above 100.000 https://pmc.ncbi.nlm.nih.gov/articles/PMC11020954/ but I get where you're coming from! The uncertainty in these data is huge.

    Now, how to prevent the attempts of big pharma to patent these to make tens of thousand of Indians/Africans pay big $$. These AI modelers are reputedly not validly a human creation = patent/copyright. These protein constructs might have a long room temp shelf life = needed in most Indian/African bite victims.

      These will probably be ignored rather than patented/monopolized by Big Pharma. A few million treatable cases per year globally, concentrated in low-income countries, is a small market to chase. Medical needs in low-income countries need to be addressed by governments or nonprofits rather than for-profit companies.

      EDIT: replaced "100,000 treatable cases" with "a few million treatable cases" per https://pmc.ncbi.nlm.nih.gov/articles/PMC11020954/ referenced by Lol_arco.

        One hopes a storable and long lasting product will be able to save many of those 100,000 deaths(??), but you are correct - it might not offer enough $$ to USA pharma?

    This means they also are amazing at designing venoms. Biological and chemical warfare in the ai age have the potential to be really fun and amusing
    • fancyfredbot 4 hours ago
      As opposed to before the AI age when biological and chemical warfare were a friendly affair?
    • squigz 2 hours ago
      I'm not a chemical warfare expert, but I feel like we're probably not limited by our own ability to come up with new ideas in that regard. I imagine we already have plenty of horrible options.

    Now do spiders.
    • jfengel 4 hours ago
      Spider bites are far less deadly. Worldwide, yearly deaths from spider bites number in the dozens, not tens of thousands.

      Spiders target small prey and it's hard for their venom to kill something as big as a person. It's certainly unpleasant and can cause significant damage even when it doesn't kill, but snakes are responsible for far more deaths.

      • lupusreal 1 hour ago
        Scorpions would be a much better candidate than spiders. They kill fewer people globally than snakes, but still thousands a year.

      And ticks.
      • cinntaile 7 hours ago
        That's not quite the same. Ticks can spread bacteria, viruses and pathogens. Venom consists of proteins. I assume this impacts development.

        Tick vaccines for different diseases such as lyme disease are in development though. For TBE they already exist.

          Anything that effectively deters or kills them without being dangerous to humans would work for me (and is convenient enough).

    > So, I love snakes: I think they are the coolest animals out there

    No they are not. Said almost no-one.

    These creatures contribute almost nothing to society and even if they're used to get rid of pests, there are other animals that do it better without being an extreme danger to humans or they can be safely caught and released.

    But instead, these creatures just want to bite, spit or strangle you if they feel like it and in some cases really just want to kill you (because they think you will kill them first).

    You cannot reason with these creatures with full of venom in their fangs even if the situation was an accident.

      Animals have to contribute to society to be useful to the ecology of our planet?

      > You cannot reason with these creatures with full of venom in their fangs even if the situation was an accident.

      You can't really reason with any creature other than a human, and that's often spotty too!

      That is interesting and I think it's a popular opinion. I think in line with the Epic of Gilgamesh or the Old Testament.

      But allow me present another opinion.

      Snakes don't do things they don't have to do. They don't kill for no reason (cf humans, cats). They do what they have to do, without much emotion or fanfare. They shed their skin and don't carry extra weight. In other cultures, a snake is a symbol of wisdom, rebirth and healing (eg the rod of Asclepius).

      Outside the symbolic arguments, I think snake venom does have some research use (eg blood thinners) and some would argue snakes are mechanically cool.

      Just another perspecive ofc, and I respect yours.

      In the end, snakes want to survive in a competitive world.

      Snakes are cuties and almost all of them are completely harmless. A great many of them have very sweet and gentle personalities.
