science@lemmy.world•This Is Awkward: Mushrooms That Cause 'Tiny Human' Hallucinations Don't Contain PsychedelicsEnglish
25·1 day agoClickbait headline, the primary object of that study was to figure out phylogeny of these mushrooms. finding no known genes associated with known hallucinogens is a bonus and pretty useless info because the compound responsible for this activity is not known, how do you know how it’s made then
or you can keep water moving and cool from one side only, then remove water from above when you’re done, no need to chip away bubbly ice

Fuck AI@lemmy.world•They put Ed-fucking-Zitron on CNBC to talk about GenAI!
30·2 days agoed has been on a full on media offensive for like a month now, he’s been on chapo, majority report and seems like any financial/economics podcast he could get into. somebody has put him on political compass type quiz thing last week. before that, he built up enough street cred to get publicly undisclosed openai audit and he’s been on bloomberg right after. financial press got some permission to talk about bubble existence after uber ceo said that they didn’t see return on investment in ai, which was some two months ago. the peak signal is there, yeah; the signal is that i hear that from top 10 fedi ai booster

2·3 days ago“hey what if we tried to make cancer grow faster” is not a great pitch
they got funding because it wasn’t what they were trying to do, but it did ended up being the case, but it worked anyway so, so far, all is good. but don’t expect that it will become a new drug, because 90% of clinical trials fail, and here maybe there is some other less malformed cancer line that will grow faster after administration of that drug, which is sort of what was could be expected now that we know mechanism

13·3 days agocells have different enzymes, enzymes do different things, to keep everything in order you need some way to control these enzymes. there are many, many ways in nature to do this, but the one relevant here is that some enzymes have tyrosine residue sticking out in a specific way. when phosphate is attached to them, extra charge appears, which can bend enzyme out of or into shape, switching it on or off or changing something about the way it works.
the job of flipping these switches belongs to tyrosine kinases, and in many cancers something is wrong about these. the ones relevant here are from RAS/MAPK pathway and PI3K/AKT/mTOR pathway, and these are involved in many things, but among them is cell growth and division. blocking one or other tyrosine kinase from working is something that many of anticancer drugs do, and it works pretty well, because overactive (for whatever reason) or mutated tyrosine kinase is often present. in many cancer cells, if for some reason MAPK is made to be more active, cancer cells might grow faster.
now the thing is, there is something peculiar about the specific way in which RAS/MAPK cascade is broken in that cancer type, that when it’s cranked up cells stop spreading and break apart. this is something that this new drug seems to be doing (through a couple of layers of other enzymes), and it’s weird, and unexpected, and in no way you’d get funding for that, but it works apparently

No Stupid Questions@lemmy.world•Would a metal gazebo be safe during a lightning storm?
8·4 days agois it grounded properly? it would be trivial to install a proper lightning protection on it with a little digging (sheet metal roof might be too thin to conduct lightning current safely and without damage. not a legal advice. consult your local building code)

Ukraine•The Netherlands is sending its worn-out wind turbines to Ukraine instead of the scrapheap
4·4 days agoI mean after refurb, because i used to know someone who bought one for too high price to ever pay off. But if you want industrial size offgrid kind of thing because regular grid is out, then math is different

Ukraine•The Netherlands is sending its worn-out wind turbines to Ukraine instead of the scrapheap
2·4 days agoDo these turbines pay for themselves in normal times? I’m not convinced. That math changes if you include price of not having power and that seems to be core issue here

you sure about it chief? bigger wheels also have larger rotational inertia

No Stupid Questions@lemmy.world•Why do tires have the width and diameter they do?
11·4 days agoThe larger the tyre (diameter), the higher the top speed achievable practically
this only holds when it’s using the same transmission?
as of width, here i think tradeoff is that with wider tire you can use lower pressure, and if it’s wide enough, also lower diameter. with lower pressure i think there might be less wear (?) but also bigger width means there’s more rubber to flex and that means energy losses by this mechanism. this is why it makes sense to use wider tires where all the power is not supplied by user
