there’s indigo and another plant that grows in europe and also makes indigo but less, so you can just farm this thing, unlike purple dye that requires tons of work, and depending on period it was used by commoners (before 1200 or so, in western europe)

it’s a bit funny to look at this today, but woad (that euro indigo) trade was a big deal, it got protected by tariffs and blockades and diplomacy, and all for nothing, ultimately both woad and indigo farming was completely destroyed by synthetic indigo production. indigo wasn’t first/easiest dye to make, but it’s far from the most complex thing you can cook, even in 1900s. prussian blue is much cheaper than synthetic indigo anyway

blue leds may fuck up your circadian rhytm but won’t give you ballsack cancer (probably)

i heard it’s because leds get brighter per mA but circuits don’t get updated and leds are fed the same current as 5, 10 years ago

fedi is always broken, and if it’s not broken enough it’s a sign to start new software so that if lemmy federation is fixed you can have new and exciting problems with mbin/piefed/lemmy interactions

even worse if admin of remote instance with open signups is awol

iirc there was a state backed bot farm on mastodon, some might have crossed over

there’s a couple of repost bots, but these are pretty obvious. you can always block them

for liquids there’s aluminum or glass

wait it’s just another spin on cellophane (with some cellulose formate)

it’s good that process uses less harmful reagents, but it’s not new-new thing

article suggests a form of intense immune response, some sugars can trip these immune system tripwires rather easily. (look up meat allergy) the proper question is, how selective it can get and what are side effects

because platinum sucks, and if you want to get real selective, you can tie together antibody and something like diphtheria toxin, but it’s not chemistry anymore, that’s firmly in biology ballpark

no because your liver makes sugars anyway. however there’s a more limited, more targeted way to deplete blood of select aminoacids that some cancers can’t make (asparaginase can be used this way)

it’s one of these things that sound good and doesn’t work. many such cases

techbros graced everyone else with disruptive, innovative methods of money laundering

it’s nit funny only if it’s your job to clean up after them
