The conditions that have led to what’s happening in the US today exist in democracies around the world.
They are an inevitable outcome of our collective failure to adapt to fundamental changes in the information ecosystem on which our democracies were originally built.

Fully agree. Our story feels incomplete to me without those things, but we simply had to get it out the door. But, I think Todd & co. are working on those follow-ups now!

of course, don't mean to imply that one method is better or more sensitive in general than the other (that depends on exp design & theoretical questions). just that they can be sensitive to different neural features.

(...but correct me if i'm misremembering)
So the decoders we used didn't require the neural signatures to be aligned across subjects, but only across sessions w/in subject. Seems likely that at finer spatial scales, multi-subj decoders would lose sensitivity more quickly than subject-specific ones.

hey thanks for mentioning David! Interesting ideas in this thread. Yes we were able to identify relatively reliable signatures at the region level. One potentially relevant difference btw our studies: our decoders were subject-specific, whereas yours were fitted on data from multiple subjs, IIRC.

It's a demoralizing time to be a US scientist but that is part of their strategy. My friend Jeff Dangl just emailed our faculty reminding us that NSF and NIH grant review panels are still being held and staff there want us to keep submitting. Stay engaged and keep fighting! 1/n

Against Language Barriers: A Call to Protect International Education in Dutch Academia

Check out our new study by @atabk.bsky.social! He tweaked a word list memory task to have hidden rules at encoding, which shifted and created β€œevent boundaries.” People recalled pre-boundary words more, and post-boundary words less. Other fun bits in the paper include a reinforcement learning model!

beautiful, heartbreaking words in this judge's rejection of trump's request

The Executive may succeed for a time in weakening the courts, but over time history will script the tragic gap between what was and all that might have been, and law in time will sign its epitaph.

Discussions this weekend made it clear that folks don't necessarily realize that our existing "scientific pipeline" of federal funding for basic research didn't just happen. The entire approach was deliberately designed to work this way, on purpose

MANY PROPOSALS WERE WITHDRAWN BY NIH ON THIS CYCLE FOR SIMILAR REASONS. Is this yet another mechanism to avoid funding research? I don't know. Chime in here if you know of other cases.

The Coming Out of a Transgender Scientist "I know that I am making the right decision because whenever I think about changing my gender role, I am flooded with feelings of relief."

We're disappointed to see Ben Barres's powerful book "The Autobiography of a Transgender Scientist" among the ~400 titles removed from the Naval Academy Library. Needless to say, we're proud to have published his book and will keep it β€” and his memory β€”Β alive.

Home - Immigration Justice Campaign We believe in a society that sees migration as a tool for liberation and prizes the dignity and humanity of all people.

Seeing a lot of anger over people in ICE detention having to eg file habeas claims on their own.

There are existing efforts to support these folks: not just full legal rep, but partial assistance (easier to scale).

Here’s one volunteer network (full disclosure: my org) immigrationjustice.us

When a person is abducted, there's a number to call to report & identify. A habeas petition challenging the abduction is electronically filed in that district, by a lawyer admitted in that district, within 30 minutes of the call. Anywhere in the country, 24 hours a day.

Nothing else is good enough.

I gave a talk Wed on the "Grand Plan," and I ended it by describing why this paper is such a big deal.

If you are interested in individual variability, precision medicince, or the RDoC agenda writ large, this is a terrific example of emergine ways to measure what we've never been able to before.

1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

I always hated the "this is the greatest country in the world" refrain, but it is striking to me that the things they are killing in government β€” an unrivaled scientific research enterprise, incredible public lands, etc β€” are some of the only things that made such a statement vaguely defensible.
