NIH Record Ceases Publication This will be the final issue of the NIH Record.

A sad day at NIH...

The NIH Record was a great way for NIH folks to find out what was going on across NIH.

Many important stories published there over the years.

How ICE Already Knows Who Minneapolis Protesters Are

A Minnesota woman observing ICE agents in her car was cornered on one-way streets. An agent approached, called her by name—citing facial recognition. Days later, her Global Entry and TSA privileges were revoked, with no explanation.

If he was then the Lieutenant Governor takes over, flatters Trump for a day or not, and keeps doing the same thing while agreeing to hand over part of the state's strategic reserve of lutefisk to cat food companies.

1/n. I agree w/ Josh's emphasis on computationally grounded approaches, coordinated x-species work, and skepticism that emotion only encompasses constructed feelings. As he notes, hierarchical frameworks can encompass multiple levels of processing,

Why emotion research is stuck—and how to move it forward Studying how organisms infer indirect threats and understand changing contexts can establish a common framework that bridges species and levels of analysis.

My perspective in @thetransmitter.bsky.social on why emotion research feels stuck and how we might move forward—by focusing on how the brain uses internal brain models to shape emotional processing across species. www.thetransmitter.org/emotion/why-...

Exclusive: key NIH review panels due to lose all members by the end of 2026 Thirteen of the agency’s advisory councils, which must review grant applications before funding is awarded, are on track to have no voting members.

🚨 New from me: Grant review at more than half of NIH's institutes could be frozen by the end of the year.

That's because crucial NIH grant-review panels are slated to be empty at those institutes by Jan 2027.

A wonky bureaucratic problem with big implications.
