I normally don't do these things but this guy is really special! His name is Lito (@avioesemusicas) and he's famous in Brazil for making really fun airplane videos, I watch them all the time too He explains how airplanes work in normal ELI5 language, and also explains airplane crashes etc, lots of people credit him for helping them stop being scared to fly as Lito showed how safe it is If you ever read Hacker News, you know about prions, which they love to discuss, they're one of the scariest things you'll ever read about, as they can flip seemingly at random in your body and cause Creutzfeldt–Jakob, a terminal disease I'm Dutch so we had a big outbreak of mad cow disease in the 1990s when I was a kid and I remember it well. You can get it from eating infected meat (but it's very rare), or prions can flip in your body randomly and cause it, or you can have surgery and one of the surgery tools can have it on them from previous patients The issue with that from what I read is that it's close to impossible to wash off, and it won't die at extreme heats either, you just have to throw away all surgery tools (which you can't) 85% of Creutzfeldt–Jakob is a randomly flipping prion though, so that's most probably Anyway, Lito here can participate in a promising trial by @Harvard @broadinstitute @ionispharma @mayoclinic but the next batch is only in October, so he's hoping the internet (like this tweet) can help him get in earlier, so he has a chance And that trial hopefully helps us find a cure for this crazy disease So if you can spread this, do so! This guy is really awesome, THANK YOU ❤️
