With all the excitement about the election I don’t want this story to get lost. This morning 8 car wash workers in Boston were kidnapped by federal agents in the largest workplace raid in the area in recent memory.

The details are horrifying.

Many of them held legal status but were unable to immediately produce their documentation to the agents, according to their manager.

thank you for all the support; the statement from our union is now live here with some more reporting.

now that this is public I can confirm that the majority of today’s layoffs were women of color. there are no longer any Black women working at Teen Vogue.
I can answer this. I interviewed Peterson's tailor a few years ago, although the interview was never published because I fell behind on work. Here is the story of this suit. 🧵

Alright, this one’s been sitting in my drawer for a year now, after @mcxfrank.bsky.social and I got turned down for a public commentary.
But before I forget about it completely, here’s the preprint:

In social movement studies, we talk about how marches and protests expand the threshold of acceptable risk so that people take more and bigger social risks IN PUBLIC, EN MASSE. This is extremely important for the bourgeois white folks holding signs and building social rapport.
Not a shitpost: #NoKings is feel-good performative activism for comfortable mostly upper and upper middle class white folks and that’s good, actually. Millions of people in the streets protesting a fascist regime is good. It is good for the normie baseline to be massive displays of public dissent.
Senator Ed Markey (D-MA) at the Boston No Kings rally today, wore the trans pride flag like a scarf draped over his shoulders and included in his speech. "Because here in Massachusetts, we stand for what is right. We stand with trans people because trans rights are human rights."

Unfortunately, when I (and others) had asked for info/guidance prior to the shutdown, “a new funding announcement is being prepared” was pretty much the extent of what was communicated — no info about what the amended timeline might look like

How do the brain’s event representations change as we gain familiarity with an experience?

Brain regions’ representations can become coarser or finer as event familiarity increases. Fine-tuning predicts memory recall.

🚨We believe this is a major step forward in how we study hippocampus function in healthy humans.

Using novel behavioral tasks, fMRI, RL & RNN modeling, and transcranial ultrasound stimulation (TUS), we demonstrate the causal role of hippocampus in relational structure learning.

Probably a long shot, but I was wondering if anyone knows anything about the NSF SBE postdoc fellowship having recently (as of last Friday) been archived without being replaced/re-issued?
