#NIH is hanging by a thread. The #CDC has been decimated. #RFK Jr. and Russell #Vought are psychopaths--I don't say this frivolously--they are cold, calculating, inflicting violence on millions through public policy. It is where we are right now. These men are not normal. 1/

Something I wish more people understood: part of the point of shock-and-awe grant terminations at NIH and NSF has been to make scientists and university administrators afraid to speak out against the administration. And it's working. But, some of us were never going to get a grant from them anyway.

One thing very few people know, even in the climate-health research space, is that - in addition to NIH / NSF / NASA / EPA blocking any new research on climate change and health - all the philanthropies have decided to take NGO-shaped roles rather than fund research, and so they aren't stepping in.
