Born in 1894, physicist Marietta Blau’s research led to a way to capture the tracks of speeding subatomic particles.
In 1937, Blau & Hertha Wambacher made a discovery that launched the field of particle physics. But she was forced to pause her work in 1938 bc of the Nazis.
Blau was nominated several times for the Nobel Prize but never won. Cecil F. Powell later built on her work & earned the Nobel Prize in Physics. https://www.sciencehistory.org/stories/magazine/the-dark-stars-of-marietta-blau/ #history #science #historyremix

QUOTE OF THE DAY
“The concept of shooting birds is awful — nobody wants that. But none of the alternatives have worked, and at this late date no other option is viable. Extinction is a forever thing.”
Naturalist Karla Bloem responds to a federal plan to cull half a million invasive barred owls (Strix varia) in an effort to save the northern spotted owl (Strix occidentalis caurina) from being the first US owl species to go extinct.

Genomic analysis suggests that the outbreak probably began in December or January, but a shortage of data is hampering efforts to pin down the source.Mallapaty, Smriti
Scientists have been absolutely clear that we MUST make immediate and drastic changes if we are to avoid catastrophic eco-system collapse. But, as Greta Thunberg has said, all we ever get from politicians and industry leaders is more useless blah blah blah…

AI-generated books on Amazon now have the potential to kill people, as they've moved into the realm of mushroom foraging. Guides have popped up like, well, mushrooms, packed with information that makes no sense and could easily be dangerous, illustrated with structures that are "the mycological equivalent of a picture of a hot blond with six fingers and too many teeth," writes Vox's Constance Grady. Here's more.

Let’s clarify:
Having a patent means only that you can stop others from making, using, selling or importing your invention – it doesn’t mean the invention works well or without risk.
“FDA approved” means a product’s benefits have been found to outweigh the risks for a specific purpose – not that it’s of high quality or low risk in general.
