Of all the harm this administration has done to US science, today's proposed changes to the way federal grants are awarded and administered is the most damaging yet.
The text of the federal register document is impenetrably tedious by design, so here's an excellent summary of what it says.

I asked the White House to explain.
“This is not a researcher entitlement program,” said an official, defending their new approach.

Federal funding of biomedical research has been a remarkably successful partnership, with benefits that are so intertwined in our daily lives that they can be easy to take for granted.
So what will we lose if the U.S. continues to defund research?
