Meanwhile, pro-democracy, pro-Europe protesters in Tbilisi, Georgia, are tonight nearing their 700th consecutive day of protest against the pro-Russian government. They haven't missed a single day in the last 23 months.

RFK: "There's five hundred million Arabs in the world. And yet they don't produce science. They don't win the Nobel Prize. They don't win the Fields Prize. They don't win the Wolf Prize. They don't produce literature."

I love society journals! One must be judicious as many are published by Elsevier, Wiley, Springer and the like so, while you are supporting the society indirectly, you may not be permitted to upload the author accepted manuscript without paying open access

Trump's closing midterms message? Gas and ass. Good luck, America.

This report is genuinely overwhelming, in terms of the evidence both against Trump and of a ham-fisted cover-up. Including one instance in which Ghislaine Maxwell was actually about to mention one of Trump's young accusers and Todd Blanche told her to stop talking.

When Trump calls women "piggy" or tells them to "shut up" when they ask him about sexual assault, this is why. We don't need eleventh level chess. The man is defensive because his history is long and sordid and unmistakeable.

God, imagine being an impressionable 19 year old kid and seeing that your own professor said this about something you’ve been hoping to study. WTF, get a grip.

“If AI continues to improve at present rate, then in a few years, there’ll be nothing human mathematicians can do that AI can’t do better” can professors please stop spreading doom. It affects undergrads & isn’t the whole point to keep future generations inspired & enthusiastic so fields dont die??

My calendar (and recent letter of rec writing spree) reminds me it is that time of year to wish for violent death to happen to programs that require those stupid fucking rankings. Those programs that have eliminated them are doing the lords work.

Are you really suggesting that reviewers should not read articles under consideration? Are authors happy with that?

JFC--they are telling us to turn over one of our most important tasks as researchers to AI. This is appalling. I also imagine someone is making money here......

How can AI support researchers in peer review? Springer Nature and Google DeepMind are partnering to co-design an AI peer review assistant that helps reviewers navigate manuscripts and focus on where their scientific judgement matters most. Learn more: spklr.io/63320EVgT8

I live in a rural town and, like, I don't know how to tell you this, but the girls play on the boys team and vice versa all the time because otherwise we don't have enough players for a game and it's literally always fine so stop being weirdos about kids sports and just let trans kids play.

Day 10, comparing only counties with Sunday voting in 2022 and 2026. Dems up 51% in these counties, about 12,000 extra votes. Pubs up just 8%, about 1,300 extra votes. 😵

Paper now out in Nat Comm by the Gatsogiannis group (wit us): Fantastic cryoEM structure of #VCP/p97-Ufd1-Npl4 with FAF1 showing how the accessory adapter coordinates Ufd1-UT3 to feed #ubiquitin into p97. Plus incredibly detailed dynamics of the complex. Thx for a great collaboration.

If Brazil can do it so can we. Democracy is not inevitable, we have to put in the work to make it happen.

The mobilization itself was already not something I ever expected to see, but to actually win? Hell, to double the winning margin from the 2022 runoff? Genuinely surreal. Maybe child raping billionaires *don't* have to run the world with a shit-eating grin. Maybe that can stop.
