while researching personalized mRNA cancer vaccines, researchers discovered that the non-specific immune effects of mRNA vaccines are strong enough that they don't need to target cancers to benefit cancer therapy

it's a silly idea but i feel a weird compulsion to create breakcore/drum&bass music videos using timelapses of the nuclear energy videos from @whatisnuclear.com . no idea who'd watch that. "breakcore mix to watch particle tracks to" "breakcore mix to install containment building domes to"

surely that gas bottle is for supplying nitrogen-free breathing air for maximum knurdness (westhunt.wordpress.com/2012/03/23/a...). the only downside is an aesthetic on the level of the golden EVA suit from the 2007 movie sunshine. or a plus if you want to be left alone...

older fuel also has less controllable burn rate due to fissile products building up, so it's more desirable to vary burn rates using fresher fuel, tho i could be completely wrong. it's interesting that i haven't seen the real rationale for this spelled out, must be another case of xkcd #2501

not sure how true, but alternative history in which the maginot line was extended and prevented surrender of france, so that ww2 never really took off.

the chinese HTR-PM600 commercial gas-cooled high temperature reactor is actually a combination of 6 smaller reactors housed in one containment building. this can be useful for doing maintenance, but i guess the moderator arrangement of surrounding the fuel load has issues scaling up.
