  • OED:

    1. totally or partially resistant to a particular infectious disease or pathogen.
    2. protected or exempt, especially from an obligation or the effects of something.

    Merriam Webster

    1. : not susceptible or responsive

      especially: having a high degree of resistance to a disease

    2. a: produced by, involved in, or concerned with immunity or an immune response

      b: having or producing antibodies or lymphocytes capable of reacting with a specific antigen

    3. a: marked by protection

      b: free, exempt

    So unless you pretend that MW’s 2b sense is the only valid one, the immunity is immunity.

    If you have a sample of HIV at 37°C in blood, but with all the immune cells removed, it’ll still all become inert after around a week simply due to chemical reactions with other components of blood etc… It’s pretty comparable to a population of animals - if you take away their ability to reproduce, they’ll die of old age when left for long enough even if you’re not actively killing them.

    • this is a shitpost community, not a biotech publication, so immune here means the dictionary definition, not any domain-specific technical jargon, otherwise people can’t make shitposts about diplomatic immunity
    • lacking the receptor that HIV uses to hijack the regular immune response in order to reproduce means the regular immune response destroys it
    • even in a normal person, after exposure, a lot of HIV gets destroyed by other parts of the immune system, often enough to eliminate it before an infection gains a foothold. Once an infection takes hold, it outbreeds the immune response as it’s the part best equipped to deal with a large viral load that it interferes with.
    • if you’ve got the virus in your body, but due to the lack of the receptor, it can’t reproduce, then it doesn’t remain viable for very long as each viron accumulates damage over time, and ceases to function once it’s too badly damaged. People carrying a disease have enough viral reproduction going on to balance out the virus being destroyed.


  • Even if you ignore that there’s an entirely valid sense of the word immune that has nothing do do with biology (i.e. the one in phrases like diplomatic immunity), my original comment is entirely consistent with the dictionary definition of the biological sense of the word. There are probably sub-fields of biology where immunity is used as jargon for something much more specific than the dictionary definition, but this is lemmyshitpost, not a peer-reviewed domain-specific publication.



  • When a normal person is exposed to HIV, it reproduces inside of them, so can then go on to expose more people, and if there’s enough of it, infect them in turn (if there’s a smaller amount, their immune system will normally be able to clean it up before it gets enough of a foothold). If someone’s lacking the receptor, then no matter how much they were exposed to, their immune system will eventually manage to remove it all without becoming infected because it can’t reproduce. If they had a ludicrously large viral load, then there’s a possibility that it could be passed on before it was destroyed, but most of the ways people get exposed to HIV aren’t enough to infect someone who’s vulnerable, let alone infect someone else via secondary exposure if there’s not been time for the infection to grow.


  • Usually, having to wrangle a junior developer takes a senior more time than doing the junior’s job themselves. The problem grows the more juniors they’re responsible for, so having LLMs stimulate a fleet of junior developers will be a massive time sink and not faster than doing everything themselves. With real juniors, though, this can still be worthwhile, as eventually they’ll learn, and then require much less supervision and become a net positive. LLMs do not learn once they’re deployed, though, so the only way they get better is if a cleverer model is created that can stimulate a mid-level developer, and so far, the diminishing returns of progressively larger and larger models makes it seem pretty likely that something based on LLMs won’t be enough.




  • Enzymes are specific to a particular molecule, or class of molecules with a particular pattern. A PEI buildplate is not getting eaten by the proteases in a dishwasher tablet. The reasons you’re not supposed to rinse things before putting them in the dishwasher are:

    • most dishwashers have sensors to detect how much material is ending up in the water, and if things have been rinsed, it can mislead them into thinking the load is lighter than it really is.
    • dishwashers replace some of the dirty water part way through the load, and the enzymes are more soluble than the dirt, so if there’s not much food residue for them to stick to, they can end up getting rinsed away part way through the cycle.
    • it uses water and your time to rinse the dishes first, which is a waste if it doesn’t make them end up any cleaner.


  • If he got incredibly lucky, they’re immune to AIDS. It’s much more likely that they’re not and will develop symptoms of new and exciting genetic disorders never seen before.

    The biggest problem was that the technique used is really unreliable, so you’d expect off-target edits to be more common than on-target ones for a human-sized genome. For bacteria, you can get around it by letting the modified bacteria reproduce for a few generations, then testing most of them. If they’re all good, then it worked, and if any aren’t, you need to make a new batch. Testing DNA destroys the cells you’re testing, so if you test enough cells in a human embryo to be sure that the edits worked, it dies. You can’t just start when the embryo is a single cell to ensure that the whole thing’s been edited in the same way as you need to test something pre-edit to be able to detect off-target edits.


  • I think it was pretty reasonable of them to worry - lots of people who don’t like spending unnecessary money also don’t like spending not-obviously-necessary money on safety equipment, and there’s plenty of material on the internet that would imply resin printing is completely safe as long as you don’t drink the stuff. Resin printing with woefully inadequate ventilation/PPE is really common, so it’s a pretty safe bet that anyone asking questions is probably also doing something unsafe without realising it, especially as resin not liking the cold is something a lot of people learn about fairly early on (unless they live somewhere where it never gets below 20°C).





  • It’s pretty easy to put something on the box like this can make your phone buzz if you forget to brush your teeth, and people who worry they’re sometimes forgetting to brush your teeth will see that as an advantage without necessarily realising that they need to give the manufacturer their email and the right to associate it with their brushing telemetry.
