Quand tu arrives à confonde "transGENIC mice" et "transGENDER mice", c'est que tu es celui qui as le plus besoin de la science que tu essayes d'étouffer depuis 2 mois.
"8 million dollars for making mice transgender" is the new "they're eating the dogs"

Is there a plausible scenario where US science funding is decentralized to the states? (Assuming we pay less in federal taxes and more in state taxes.)

Nice story on fabulous new work from @dingliu.bsky.social in my lab, just out today!...
Two dueling sets of hypothalamic neurons—one that responds to isolation and one to reunion—help maintain a mouse's social homeostasis, a new study reveals.

Soft touch quells loneliness in mice
Touch modulates one of two dueling types of hypothalamic neurons that, thermostat-like, balance an animal’s drive for social interaction.

Our new review article with @michelcayouette.bsky.social is out on temporal patterning and glial reprogramming in adult CNS, and its implications for treating degenerative diseases. All work from our lab discussed here was funded by NIH.

Come along to my (free, online) UCL NeuroAI talk next week on neural architectures. What are they good for? All will finally be revealed and you'll never have to think about that question again afterwards. Yep. Definitely that.

"We introduce a modern Hopfield network with continuous states and a corresponding update rule. (...)
The new update rule is equivalent to the attention mechanism used in transformers. "

How do hibernators survive for months without water? Reduced neuronal activity in the CVOs is key! www.science.org/doi/10.1126/...
Suppression of neurons in circumventricular organs enables months-long survival without water in thirteen-lined ground squirrels
Water deprivation is a life-threatening condition that engages a protective physiological response to couple osmolyte retention with potentiation of thirst. This response, typical for most mammals, sa...

If you scan all the code you can find and create a statistical model from it, and invert the model to create code, the output will be on average not good, just average. Also the code that comes out will not have been written by anyone on your team so when it breaks you have no one to ask about it.
A study measured the performance of 800 developers before and after getting GitHub's Copilot.
It found:
- No change in productivity
- No change in burnout levels
- A 41% increase in the bug rate!??
Aren't you thrilled we're burning the world to power these AI models?

Devs gaining little (if anything) from AI coding assistants
Code analysis firm sees no major benefits from AI dev tool when measuring key programming metrics, though others report incremental gains from coding copilots with emphasis on code review.

I went to a national astronomy event the past week-end and the astrophysics QA fell short of my expectations. I was specifically interested in the perspective of this pub.: arxiv.org/html/2401.12.... I have enough knowledge to understand it., but not enough to assess whether it's sound.
