"The Trump Administration is proposing to repeal the Roadless Rule, opening 45 million acres of national forests to road construction, destructive timber harvest and energy development."

Today is the last day for public comment. Weigh in: defenders.org/roadless-rule

About half the oxygen you breathe was made by phytoplankton. A year of them from orbit, Sept 2025 to Sept 2026, on a map where every ocean is one body of water. Watch the polar night swallow each pole in turn.

A 10K contribution and a $900 million return. The scale of the graft in Homeland Security is a) off the charts and b) possible because no-one believes they will face any accountability

In her last hours as DHS Secy, Noem's agency bought 5 planes from a donor at markups. In all, DHS gave $900M in contracts to that donor’s companies during her term. One plane had electronic bidets, 2 bedrooms, bar, wine chiller, a manta-ray skin table. www.nytimes.com/2026/10/04/u...

This paper doesn't really present direct evidence for pre-Cryogenian or even pre-Ediacaran animals. It overturns a bad taphonomic constraint that had been used to force molecular clock estimates indicating an Ediacaran origin, but revised estimates still need to be taken with a bucket of salt.

My inbox is being flooded with fully AI-generated emails from prospective students. I tried to work out why I can't bring myself to read them, and ended up with some thoughts and advice for writing cold emails in the age of AI.

Killed. NSF’s SBE was killed, in violation of law. The President does not have the power to choose to kill programs at a whim by defunding them. The imperial presidency was a mistake and we are in a separation of powers constitutional crisis.

The administration has found yet another way to fuck with solar power.

canarymedia.comThe USDA just made it way harder for farmers to get grants for solarEven farmers who were already promised funds from the REAP program may never get them under the Trump admin’s new restrictions. Some are suing.

Surveys have found that only a few hundred mountain yellow-legged frogs are left in the wild in SoCal. This year our partners group released hundreds more. @mongabay.com covers the reintroductions and the fight against chytrid. 🐸

Or with a Niklas-style exploration of fitness tradeoffs and adaptive landscapes

@sethf.bsky.socialOct 1, 2026, 3:57 PM

That would be very cool, especially if integrated with some biomechanical modeling...
