  • The side effects they’re finding are that it unexpectedly prevents Alzheimer’s symptoms and other neurodegenerative issues, influences the brain to want to drink less alcohol and smoke/vape/chew less nicotine, and helps with chronic pain.

    The point, though, is that it makes metabolic changes by having people eat less. Pointing out problems with drugs that increase resting metabolic rate (so that they burn more calories without exercising) or decrease absorption of macronutrients in digestion (so that they take in fewer calories from the same food) doesn’t really inform how we look at these behavior-altering and desire-altering drugs. They’re losing weight by eating less, not by interrupting the relationship between eating and net caloric intake.



  • You’d never get Kessler syndrome at Starlink altitudes.

    Starlink satellites orbit at around 550km, and get dragged by the little bit of atmosphere that is at that altitude. Each collision might make more debris, but the conservation of momentum means that any debris that gets kicked to a lower orbit will probably burn up on the atmosphere while any debris that gets kicked to a higher altitude will be smaller mass and therefore cause less damage on the next collision after that.

    Collisions can still happen, but the runaway conditions where debris begets debris won’t happen at those orbital velocities and altitude.







  • I weigh my coffee/water to keep the brew ratio the same

    Yeah, I developed my current routine by weighing, but because I use literally the same containers every morning I can eyeball the amount of beans or water in those containers and know that I’m basically at the ratio I used to measure. Maybe tomorrow I’ll eyeball it, and then measure, to confirm I’m still calibrated at the right level.



    1. Don’t feed wild animals. For this rule, the particular type of food doesn’t matter. Wild animals are harmed from human feeding, even if the food is nutritionally beneficial to them.
    2. Bread spoils fast, and spoiled foods in the environment can make a lot of animals sick.
    3. Bread doesn’t contain the nutrients that many birds need, so birds (especially young birds) that eat too much bread at the expense of not eating other foods might become unhealthy from deficiencies on other fronts.

    I point out these three distinct reasons because the overall points being made don’t make it OK to feed wild ducks peas or whatever else. For farmed animals, though, farmers will want the overall nutritional profile to meet some standard, at which point old bread and other scraps could very well be part of a broader diet, in a way that manages household waste.







  • No, it’s a guy who edited the genes of some embryos in the hopes that a particular gene mutation would give resistance to HIV.

    Only: the gene editing didn’t actually give the specific version of the gene studied to have an effect on HIV susceptibility, the gene is also associated with memory and other brain function, and the gene was incompletely edited so that there are multiple versions of the genes in both kids, when the studied mutation needed to be present in both chromosomes of the chromosome pair in order to show some kind of effect on HIV.

    Even if you believe that the evidence is strong enough to support the idea that a mutation in this gene can give HIV resistance, this guy didn’t actually do it in a way that was scientifically sound, and now two real human beings have to live their lives with the effects, including any off target effects, whatever they might be.
