We didn't buy one but it does look mildly handy for stuff like a family calendar app that would sync to everybody's devices... but not worth it to have it built into the fridge vs a standalone device a la Google Hub or DIY. Certainly I can't see paying extra to have the screen to have ads on the damn thing.

I could see a rise in more anonymous conversation places like this one, although maybe Discord scratches that itch for the younger crowd? I remember back in the day when posting online was an exercise in not doxxing oneself, but then Social Media really encouraged folks to post their real name alongside stuff that occasionally gets them fired or harassed.

https://www.ncbi.nlm.nih.gov/b... No, this is intro to immunology stuff. You'd have to explain why you'd expect chiral preference from random assortment of the binding site. It'd merely take two different antibodies, one for each spin. It isn't like an enzyme's binding site that needs a large area to match.

If you just want to cover the flavor, you can get a soda stream, carbonate it, and drip in a few drops of your favorite citrus and its pretty refreshing without adding sugary drink mixes or taking the time for tea. When the CO2 runs out you can swap them at Target and other grocers.

Proof? It's basic immunology for how antibodies are made. Random reassortment, downselection of overbinding and self-binding which causes apoptosis. Then distribution to lymph nodes and the b cells wait around for activation. Upselection and redistribution for activated b cells, which gets you immunized to something you ran into or perhaps sensitized to an allergen.

Different species, yeah. Like pre-cretaceous there's no flowering plants, frogs, no mammals larger than a dog. And that's just conspicuous land biosphere stuff. Very different from anything humans have lived in. Like if the ocean got too acidic for most fish there'd still be life there but it'd be weird to us, lots of jellyfish, some squid. Not much good to eat without lots of processing.

Yeah its the kind of thing that would either starve immediately or have the potential to grey goo us with incompatible amino acids. It seems more likely if it did get a foothold that our native prokarya and archaea would figure out some enzymes of their own before too long just given the breadth of them. What impacts this would have on megafauna and megaflora would be more unpredictable. Low level, I'd think antibodies would still work, so it might not doom vertebrates. But clearing large amounts of reverse aminos from food might hurt digestion efficiency greatly. Ruminants might not care much but maybe things like obligate carnivores go extinct. Eusocial insects might just fine new gut biomes and be fine. Lichens would presumably also just adopt both types of flora if they made it that far.
