I have often been critical of the leadership @aaas.org but they just took action on the new OMB rules that will politicize science, speaking out and notifying members. I hope all take the time to follow their advice, contact Congress, and most important, post a comment www.aaas.org/news/aaas-st...

Scotland rightfully proud of him this year. His great contribution was to proffer a wide-ranging Earth model strongly based on observations and unbound by Biblical time -- plus living in the right place and time.

I'm writing an NSF grant proposal now. How do I justify spending my time writing proposals to an agency that is targeted for a greater than 50% budget cut, has made almost no new awards in 2026, and clearly is being destroyed from the inside out according to the Russ Vought playbook?
