@josueortc.bsky.social @wutsaiyale.bsky.social explored spatiotemporal cholinergic & calcium signalling dynamics across learning.
🎨Using dual-color imaging and multimodal transformers 🤖, he showed how cortical neuromodulation reshapes with experience and task demands.

Earlier this year, after receiving emails from people in the throes of AI psychosis, I stayed in touch with one man as he journeyed to recovery.
I'm grateful to James that he was willing to go on record. He wanted people to know: humanlike chatbots are dangerous.

What problem is explainability/interpretability research trying to solve in ML, and do you have a favorite paper articulating what that problem is?

IMO, the #1 personality trait for a successful scientist is perseverance and #2 is a deep (insatiable) curiosity (dopamine!) about the world. After that is luck/serendipity, decent intuition and way down the list is “good grades”, problem solving or some other measure of intellectual capability 1/2

The White House is taking new steps to undermine every international student at our universities.
It has approved a new rule restricting student visas to 4 years max. That's not long enough for PhD students, or about half of undergrads, to finish their degree.
Likely to enter force within days.

The GAO just found the Trump admin illegally delayed/cut $8B+ in NIH research grants—blocking Congress-approved funds, harming medical research, and violating the Impoundment Control Act. Science, equity, and accountability are on the line. Congress must act. www.highereddive.com/news/nih-cut...
Trump administration illegally axed NIH grants, government watchdog says
The U.S. Government Accountability Office can file a lawsuit in an attempt to restore the grants, though the agency has not yet opted to do so.

Some people don't feel as close to this as they ought to. Most of us are just a bad break or two away from winding up on the streets, and addiction & mental health crises can affect anyone. They're gutting services and rendering more of us disposable, and there's a carceral disposal system waiting.

All of NIH funding to Northwestern University is frozen. This pause includes noncompeting approved funding, new and competing grants with fundable scores. No reimbursements for money already spent have been received since March. This situation is rarely reported so please Please get the word out!
