Last year, based on the previous funding cuts, professors in our field told us to start planning for a backup career. Now we are facing more funding cuts, they should probably just train us explicitly for the backup career.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

Which just makes me want to share it again: www.nature.com/articles/d41...
Gladys Mae West obituary: mathematician who pioneered GPS technology
She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

Early-career researchers are rightly worried about the road ahead, and have drafted an open letter to UKRI & #STFC, calling for a "strategic correction" to avoid irreversible loss of curiosity-driven UK research - an essential part of future discoveries, tech, & growth. bsky.app/profile/si-w...
We’ve drafted an open letter from early-career researchers in response to UKRI reprioritisation and the funding crisis in Particle Physics, Astronomy and Nuclear Physics (PPAN).

This risks losing an entire generation of young researchers from UK science. We cannot let that happen.

I've posted this before, but what is the point of "Letters" anymore? I don't remember the last time I saw a paper where a quick turnaround was warranted. Our journals usually only use a single referee, so adding the additional time pressure is only further hurting quality. #exoplanets

A great paper examining the hot Jupiter HAT-P-30b, lead by final-year PhD student Alastair Claringbold (@exoarcturus.bsky.social), as a part of the BOWIE ALIGN program. The program aims to understand how migration history impacts atmosphere composition. #exoplanets

You and 24 of your friends (and/or enemies, as you like) can have AAS journal editors come run a workshop on how to be a good referee!
🔭We normally hold these Sunday mornings before the start of AAS meetings, but we are willing to hold them in cooperation with local organizers if we have 25 to 30 people signed up to participate. We did this at IU this Fall and brought in four editors to run the meeting and lead discussion.

just so it's clear: this is the exact core function of genAI

Fascist government and climate deniers love it because it can produce the aesthetics of knowledge without any actual tendency towards truth. It is automated denialism.

Shame on every climate scientist promoting its use (there are lots)
Bob and I were among the hundreds of researchers that were supposed to conduct the 6th U.S. National Climate Assessment. Now it looks like they're gonna produce it with a few people and Grok? Communities need rigorous and accurate information about climate change. This will put communities at risk.

NCAR is quite literally our global mothership.

Everyone who works in climate and weather has passed through its doors and benefited from its incredible resources.

Dismantling NCAR is like taking a sledgehammer to the keystone holding up our scientific understanding of the planet.

Unbelievable.
