I am being asked to tell my department which pieces of lab equipment should be supported with backup power because they expect rolling blackouts and brownouts in 2026 due to increased energy demands from AI. In case you're wondering how my day is going.

The GRFP announcement from NSF cuts out an entire cohort of 2nd year students from consideration, without warning. This is so deeply unfair that it warrants a formal protest from the scientific community. If someone wants to work with me to craft an open letter and solicit signatures, LMK.
New: After a long wait, the GRFP solicitation is live! Deadlines have been extended to early November, so applicants have a bit over a month to submit. www.nsf.gov/funding/oppo...

My first first-author paper came out yesterday online-first in #Oecologia! We reported that neotropical swollen-thorn acacias increased their investment in mutualism with ants during an El Niño drought event. Mutualism may indeed be strongest during tough times.

And PIs, don't tell your students/postdocs to do it, even if *you* did and were okay in the past! They may not feel like they can push back if they're not comfortable, and the stakes have gotten a lot higher.

The time for everyone to be cute with the rules is over, especially if you are not a U.S. citizen. By the book, people.
And honestly for the time being, maybe decide if you need those specimens or if a colleague outside the U.S. can do the work.
