  Eh, the giant panda isn’t the best example. It’s digestive system is still optimized for meat, which is why the need to eat a lot of bamboo and eat very specific parts of it that have a similar nutritional makeup as meat. They wouldn’t be able to survive eating other plants, but they could survive (and thrive) eating meat.

  That’s kinda misleading though. Large molecule PFAS are harmless to us (Teflon for example). It’s the small molecule PFAS are dangerous and those aren’t really used for any kind of non-stick surfaces.

  That phrase first came out when incandescent bulbs were the most common, so they consumed like 60W vs 7W for an equivalent LED bulb. The brain is somewhere around 20W.

  A study in Canada was published in 2019 looking at the differences between 2 neighboring cities where on stopped fluoridating water in 2011. They saw that saw a significant increase in cavities in children in the city that stopped fluoridating vs the other. This is despite the fact the the city without fluoridation actually has somewhat higher adherence to brushing, flossing, and going to the dentist. No difference was seen yet in permanent teeth, but that’s because the study would need more time to see effects there.

  Of course, we still should do more studies on fluoride neurotoxicity. Most studies look at levels of fluoride at 1.5mg/L or higher, which is more than double the recommended level by the US (0.7 mg/L). There is a hard limit in the US of 4mg/L, but the EPA strongly recommends a limit of 2mg/L. This only really matters for locations with very high levels of fluoride in the groundwater, and is thus quite rare. The EU’s limit is 1.5mg/L.

  Fluoride in the water is beneficial in the pre-eruptive phase (when teeth are still growing). Fluoride ingestion increases tooth resistence to cavities if the ingestion happened while they were growing.

  This does mean that fluoride in water isn’t really useful after you have all your permanent teeth though.

  To be fair, the star system was garbage. I agree with the rest though

  Just because Russians can’t approve commits anymore?

• ⁨Comment⁩ on ⁨Linus Torvalds affirms expulsion of Russian maintainers⁩ ⁨⁨11⁩ ⁨months⁩ ago⁩:

  Russians aren’t restricted from getting their changes submitted, they just can’t be maintainers. This means that they need another maintainer to approve their changes, just like if you or me were to submit a change. A lot of people seem to be misunderstanding what actually happened.

  Capsaicin is a fungicide, which is extremely useful in the environments where spicy peppers grow.
