Washington Post article on STEM cuts at federal agencies. NSF tops it at -42%!

Washington Post article on STEM cuts at federal agencies. NSF tops it at -42%!

“Between January 2025 and February 2026, STEM and health employees at science-focused agencies saw nearly 15,000 jobs cut. The rate outpaced cuts among other federal workers.”

OPM data - Figure from Wash Post article 19 April. (Where US science has been hit hardest.)

NSF at -42%!

a Uloborus spider wrapping prey

these spiders lack a venom apparatus (rare in the spider world!), and instead secure their prey in a tidy silken ball, combined with toxic digestive fluids!

look closely and you can see silk strands coming from the spinnerets

Two flies with red eyes that are shaped upward like horns. The flies have pale legs and undersides with brown on the top of the head, a brown and tan striped scutum, and a dark brown and pale striped abdomen. The fly on the left is getting ready to shove the fly on the right with his front leg.

Just a lil guy defending his mushroom.

We found a log covered in mushrooms and spotted some small hammerhead flies on it. Turns out these are feisty fruit flies and the males are serious about defending their patch. One of our coolest finds so far! #invert

We call ourselves "intelligent," yet the humblest fungus can decompose waste and build soil, a tree can harness solar energy, and a wetland can purify water—all without toxic byproducts. True intelligence is learning from these systems, not bulldozing them.

Look at the women at NASA.

They are the ones pushing the boundaries of science, solving problems most people can’t even understand, and carrying this country forward, while our politicians right now posture and stumble through talking points.

And they are doing it all with joy.👇

The spider looks so innocent sitting there eating a fly while two other flies look on. Who, me ?

Awesome series 👍

Humanity did that. Science did that. Publicly-funded research did that. Excellent universities did that. Diversity did that. International cooperation did that.

Artemis II is a perfect example of what we can do at our best.

Welcome home, Integrity crew!

The machines are fine. I'm worried about us. On AI agents, grunt work, and the part of science that isn't replaceable.

Hey, I wrote a thing about AI in astrophysics

U.S. Forest Service unveils extensive closures of research facilities Cost-cutting move is expected to cause resignations and turmoil

What will happen to the 82 USFS experimental forests around the country? Many sites have decades-long experiments that are tracking how forests are changed by timber harvesting practices and climate change. As I say here, “you can't just pick up an experimental forest site and move it to SLC.”
