The NYTimes article on Mamdani at Bowdoin is "a wreck, but of a form so pure, so purely Timesian, you almost have to admire it. It certainly is instructive." lithub.com/maybe-dont-t...

What a beautiful agrivoltaics facility Majdi Abou Najm and @ucdavis.bsky.social colleagues have built. Thanks for the fantastic workshop and tour!

Why is it always so tough to log into Editorial Manager to do a peer review. If journals want me to do a peer review, they should make the process as seamless as possible. I shouldn't have to track down a login that was created for me despite already having four for the same website...

So they didn’t like the ad. Let’s just post Reagan’s 5 min speech against tariffs as it appears on YouTube.

Over and over. On all platforms (some of y’all are still on X).

My colleague @sarahhird.bsky.social has been fighting for family care leave for over a year now. So impressed with her leadership!

ctmirror.org/2025/10/21/t...
Opinion: This is UConn: Zero paid family leave for professors
UConn currently lets every pregnant/expecting individual reinvent the wheel, cobbling together a leave plan with whatever resources and departmental grace they can muster.

Americans have been dragged, tackled, beaten, tased and shot by immigration agents.

They’ve had their necks kneeled on.

They’ve been held outside in the rain while in their underwear.

At least three citizens were pregnant when agents detained them.

More Than 170 U.S. Citizens Have Been Held by Immigration Agents. They’ve Been Kicked, Dragged and Detained for Days.
The government does not track how often immigration agents grab citizens. So ProPublica did. Our tally — almost certainly incomplete — includes people who were held for days without a lawyer. And near...

Purdue to the rescue of IU student newspaper, whose institution was attempting censorship. Details in alt!
Sara Whitmer • • • 1h • 8 I'm sure many of you have heard by now that earlier this week, IU k*lled the print edition of its student paper, the IDS. The issue that was supposed to print this week contained criticism of the Whitten regime and IUs further slide into scist control, and they couldn't allow that to happen during Homecoming, when all the rich alumni are in town. Enter Purdue! The Purdue student paper, The Exponent, owns its own presses. Yesterday, in an act of tremendous solidarity with their biggest rival school, they printed the forbidden issue of the IDS. They then drove it to Bloomington overnight and stocked all of the IDS boxes on campus, just in time for Homecoming. Solidarity is what makes us stronger, and solidarity will be what ultimately allows us to triumph, if we can ever truly get it together. I hope everyone has a fun, safe day if they're going out today, and I hope we can think about what acts of solidarity we can begin taking to really make this movement MOVE - beyond a permitted expression of upset into more active resistance. 75 12 comments
