Hugely important point! Industry takes risks in developing drug candidates and then bringing chosen ones into clinical trials. Academia takes risks in developing students and helping them become more capable of being independent scientists in industry, academia, and other sectors.

"NIH officials are telling grantees who submitted annual progress reports [...] to remove papers that name co-authors affiliated with foreign institutions if NIH had not previously approved a foreign component." Sad and absurd in so many ways.

A really good explanation of why relying on cherry-picked science to draw a Tylenol-autism link (as RFK seems poised to do) is really harmful, along with a reminder that Tylenol deserves a lot of scrutiny for other reasons. open.substack.com/pub/insideme...
open.substack.com
Tylenol has entered the chat: RFK Jr. wants to link it to autism, even though the best evidence says otherwise.
It's not pseudoscience. But it's not settled either, nor is it "safe" to assume otherwise.

I stand with Joachim Frank. I would hope that others would have had a better understanding of history. 2/2
Joachim Frank, a German American biophysicist at Columbia and 2017 Nobel laureate in chemistry, said he was outraged by Columbia’s unwillingness to litigate instead of negotiate. The stance, he said, had emboldened Mr. Trump to ask for even more money from other universities. Dr. Frank called the administration’s decision to withhold funding over accusations that Columbia had tolerated antisemitism a “ruse for the government to take control of the universities, in a model essentially similar to what happened in Hungary and Turkey.”
