This is worrisome for the future of R&D.
Across scientific disciplines, US university departments are cutting the numbers of PhD candidates they plan to accept in the current application cycle, for students due to begin in 2026, according to a Nature news article. Some plan to pause admissions altogether. #Academicsky 🧪
US PhD admissions shrink as fears over Trump’s cuts take hold
Some doctoral programmes are admitting no students at all amid uncertainty about federal science funding.

Trump will probably ask for a Nobel price in Physiology and Medicine for his discovery that acetaminophen causes autism. Such lies and falsehoods will cause real harm and cost lives.

1/ Last night, RFK Jr. announced the cancellation of $500 million in mRNA vaccine research. This means 22 projects, many in active clinical trials, are just... stopped. RFK Jr. stated the #mRNA "poses more risks than benefits," but that claim is simply not backed by science. 🧵
