RIP Margaret Hamilton, the brilliant computer scientist whose contributions to software for the Apollo Guidance Computer were absolutely crucial to the Apollo Moon landings. She also helped shape the discipline of computer engineering while at MIT's Instrumentation Lab: news.mit.edu/2026/margare...

Agency-wide, NSF made far fewer new grants (~6,200, down from an average of ~11,000) and underspent its buget by 1.4 billion. See previous coverage:

The US science-funding agency is withholding $1 billion of its budget so that the money can go to a special White House project.

89% of SBE NSF grants were never awarded!! My field (Cognitive Neuroscience) is included in this gutting, as are so many others. Plenty of horror stories in the same space are also coming from NIH. It’s not just delaying research; it’s labs shutting down and a next gen that won’t be trained.

I don’t think everyone realizes how bad things are for US science: For the fiscal year that just ended, the Trump regime withheld $1.4 billion from the National Science Foundation’s research budget, which is about 1/5 of its primary research budget.

The move, affecting about one-fifth of the National Science Foundation’s primary research budget, is the latest sign of how the White House is asserting more control over grants.

Not really a prank, But whenever after school activities ended, I had to notify my parents to pick me up. I would use the pay phone to call collect & say my name was "Anita Ride". When the operator asked "Will you accept the charges?", my parents would say "No" (but then leave to get me).

For folks asking why bother commenting because the OMB won't care: comments help build cases for the courts by explicitly laying out harms. That's why it's really important to have your comments be as specific as possible. Also, contact your senators and reps! They actually do care about this.

Elizabeth Bonawitz @ebonawitz.bsky.social · 12/07/2026
Right! Furthermore, the OMB has to read & respond to all new comments (this slows them down, forces them to engage with the potential impact of these policies). And additionally, a strong showing by the public tells politicians we care about this and so they pay attention and care more too.
