I can't stress enough how close U.S. science is to the cliff.

"Numbers released in May by the National Science Foundation (NSF) indicate that if Congress approves the cuts to the agency proposed by the White House, the number of early-career researchers it supports could fall by 78%" (@science.org)
‘It’s a nightmare.’ U.S. funding cuts threaten academic science jobs at all levels

Because no one spends as much on science as the US does, destroying NIH, NSF, NOAA, NASA, EPA, USDA, USGS, etc. is leading to a brain drain, but it's not to other countries but rather from science. This senseless destruction of US science will hurt the US and the world for a very long time.
davidho.bsky.social
David Ho @davidho.bsky.social · Mar 11
To see why destroying the US science enterprise is so detrimental to the world, we have to realize that the US spends more on research and development than any other country in the world (by far), and if we remove China and Japan, the US spends almost as much as ALL other countries combined.
Bar graph titled "Top 20 Countries by Research and Development Spending." The United States leads significantly in spending, followed by China, Japan, and Germany. Other countries include the United Kingdom, South Korea, France, and Australia, among others.

The NSF has frozen all research grant awards—cutting off life-saving science midstream and demanding ideological screenings for future funding.

This is censorship disguised as oversight.
