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?
2·7 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

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

4·11 days agomethane cracker? that’s a very unusual unit that outputs hydrogen and carbon. i could find info about opening of ethane cracker in 2025, but that’s for plastics, next to shutdown of another similar unit

Ask Lemmy@lemmy.world•How can you detect cancer spreading Nitrates in the water supply?
7·13 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

Ask Lemmy@lemmy.world•is it a good idea to put foamboard covered with aluminum foil on top of windows in my attic?
4·19 days agoReflective side out, and on the outside this should work. Aluminum foil or a thermal blanket would also work and are lighter

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.

67·25 days agohornyposting on main must be one of these elusive family values then i guess
AC also needs to deal with line resistance, and cheap, efficient multi-MW, multi-kV DC/DC converters aren’t there so far, but there are prototypes (and drop-in transformer replacements https://en.wikipedia.org/wiki/Solid-state_transformer) Advantage is that these converters can be more efficient than transformers and you don’t have to deal with reactive current (if DC). Obvious downside is that frequency control isn’t there
if power electronics get a bit better than they are now, we could switch to DC power transmission and DC/DC converters instead of transformers. bunch of infrastructure could be replaced one by one, but benefit is slight except for already used undersea cables
but on generation side, it’s either photovoltaics or spin a magnet

No Stupid Questions@lemmy.world•Which path would the electrical current take?
24·26 days agoIt’s easier to see that this circuit is rather symmetric when you redraw it

Then with both switches closed blue wire (the one in the middle) should only carry small current. If both halves are exactly the same it should be zero
In general when circuit doesn’t include nonlinear components (semiconductors most commonly) you can sum two valid solutions and you’ll get another valid solution. Note that when one switch is closed, current in blue wire goes one way and when the other is closed, in opposite way



rtl-sdr uses the same chip as dvb-t tuners, but the everything else part is completely different
