LG would be South Korea. Maybe it contacts tracks on PCB below and it’s some kind of semi-conductive rubber

No Stupid Questions@lemmy.world•If someone's injected with cancer cells, they develop cancer. Could at least part of the increase in cancer be to do with people getting other people's cancer cells inside their bodies?
0·7 days agocancer is in large part an old people disease, if you avoided dying of cholera you’re more likely to die of something else. also now there’s a lot of people who were exposed to carcinogens decades back, and we got better at treating pr preventing some other common causes of death like stroke or heart disease

Technology@beehaw.org•A Finnish town is heating itself with 2,000 tonnes of crushed rock: its giant “sand battery” can cover almost a month of heating demand and has cut district heating emissions by 70%

1·11 days agoThis will continue as long as there are CCGTs used as baseload, then it will drop as CCGTs (and biomass + waste burners) will cover the gaps

Ask Lemmy@lemmy.world•How can you detect cancer spreading Nitrates in the water supply?
0·13 days agoyeah this is only practical option, the analysis isn’t that expensive, but equipment to run it is. but also people who have their own water wells have to submit their own samples

News@lemmy.world•Trump orders Pentagon to redesign US aircraft carrier to use steam catapults to launch jets
1·14 days agoNo they don’t, there’s still 4 units one per launcher. Most of problems you mention seems to come from energy storage system. Energy is stored in the flywheels, which requires annoying converter, so chinese variant uses giant set of supercapacitors instead which is just a bit heavier and has less problems with communications interference. Also can be split in many parts and fit in any space you have. Mostly benefit of being designed later. Zero surprises if americans figure it’s better but institutional inertia keeps them using the old one

News@lemmy.world•Trump orders Pentagon to redesign US aircraft carrier to use steam catapults to launch jets
2·14 days agoThey don’t actually. Steam catapult is operated with completely separate steam supply, and major design goal of ford class was to remove it so even if pedo in chief wanted, retrofit is physically impossible. That separate steam supply needs extra freshwater because it’s not condensed and recovered. EMALS is much milder on plane and pilot because it’s a big linear motor that gives constant acceleration instead of spike then decreasing like with steam. Efficiency of steam catapult is also dogshit compared to turbine + energy storage system

Ask Lemmy@lemmy.world•is it a good idea to put foamboard covered with aluminum foil on top of windows in my attic?

Once Evo got familiar with the genomes of Phi X-174 and its kin, the researchers prompted the model to write new versions of its own. Evo generated 700,000 potential versions; the scientists pursued only the ones that looked as if they had the best odds of succeeding.
They ended up making DNA molecules from 285 of Evo’s suggested sequences. […] All told, they discovered that 16 of Evo’s genomes produced viable new viruses.
Dr. Crook cautioned that Evo’s viruses were not radically new creations. They tend to be very similar to natural species, relying on the same underlying biology.
