The 40s and 50s where the decades for unethical human experimentation. There's all kind of random shit that we shouldn't know, but do know because of that period.
That was the era of more horrifying and particularly bad science. The 50s though, that’s the era that brought rules like “you have to provide an honest explanation of what you’re testing to human test subjects” and no they didn’t just think it up as a good rule to have out of the blue.
“This discovery could be revolutionary. Imagine being able to monitor organ function without invasive procedures, or see precisely where a vein is to draw blood. It could also pave the way for breakthroughs in understanding how diseases affect the body at a microscopic level.”
I once wrote a short paper for a high school science class about MKUltra and the Holmsburg Prison Experiments. Nothing quite like heading a supposed man of science refer to a bunch of humans like they are cattle.
