We noticed something interesting (and frustrating) this winter because we had a number of cold spells here in Florida - when humidity drops, the food in our cages loses moisture and therefore weight, artificially increasing our food consumption measures. Curious if anyone else has noticed this?

Asking an LLM to provide step by step instructions on how to disable the LLM is one of only a few legitimate use cases.

Room with sex criminal donor in it

Even if he smiles
at you

Even if his publicist
says he thinks you’re smart

Even if he shares your passion for evopsych

Even if it’s Jim Watson’s birthday

If your institution, like mine, complied in advance with the unenforceable "Dear Colleague" letter, I hope you're asking leadership how these programs are being reinstated.

This training was excellent. We did 2 roleplays of an ice raid. We did so much better in round 2. It was helpful both in concrete learning terms but also in confidence building.

Some clinician friends have told me that for them, this means seeing patients, but not billing - still participating in the good, impactful aspects of work but while having economic impact. This is the energy I'm trying to channel.

I'm trying to figure out what participating in a general strike looks like as an academic scientist in the current climate. Some thoughts, but I'd love to see more -
- declining admin tasks (sorry not sorry to Concur)
- not placing orders/spending money
- working on anti-AI policies for lab/syllabi

Trump administration sends letter wiping out addiction, mental health grants The Trump administration sent hundreds of letters Tuesday terminating federal grants supporting mental health and drug addiction services. The cuts could total as much as $2 billion.

β€œThis cruelty will be measured in lives lost… We are witnessing the dismantling of our recovery infrastructure in real-time, and the administration will have blood on its hands for every preventable death that follows.”

Given the current news... for people not in Philly, this is just a reminder that you do not, under any circumstances, "gotta hand it to them."

Talk is one thing, but it hasn't kept my neighbors safe.

My experience with this is that I can *always* access in incognito, so i do this for compulsive checking. But it also works if I clear my cookies, so for e.g., section day or RPPRs or something, this has consistently helped.

Heads up I will be hiring a postdoc and some techs in the new year! Lots of ephys and fiber photometry. If you've got soon to graduate PhD students or undergrads, send 'em my way!

How basic neuroscience has paved the path to new drugs A growing list of medicationsβ€”such as zuranolone for postpartum depression, suzetrigine for pain, and the gepants class of migraine medicinesβ€”exist because of insights from basic research.

β€œBasic neuroscience hasn’t produced new drugs.” πŸ’Š

Not true - zuranolone (PPD), suzetrigine (pain), gepants (migraine), and more... were born out of a long arc of studies in the lab.

I wrote a Perspective on why this matters. @thetransmitter.bsky.social

I am just saying that community fridges are great, consider supporting ones in your community. But also consider this one in South Philly, where you can support with a donation AND this excellent spooky season merch.
