How Congress can restore the independence of US science Members must go beyond reinstating US government research spending and re-establish decentralized governance at the National Institutes of Health and other agencies.

The most impt change at #NIH and to US science this year is bigger than grant cancellations— it’s how the agency is governed.

For 75 years NIH has been largely independent of presidential control. That’s changed this year. New piece from me and @nataliebaviles.bsky.social in @nature.com

Two-photon calcium imaging at 24,000 lines/s, with the resonant axis spanning 4x what other systems can do. Inertia-free. Diffraction-limited. No tradeoffs. Che-Hang Yu developed a 4x angle multiplier for laser scanning. His paper is out today: opg.optica.org/optica/fullt... 1/n #fluorescenceFriday

Embedding unreliable AI deep into the source code of the military without human oversight is the single stupidest thing we could do as a species.

And that is *exactly* what the United States is about to do.

Yes! Some clear thinking. Once we move away from "species x is a good/bad model for y because of z handpicked reasons" we can do science.

In 2023 a bill to prevent AI from autonomously launching nuclear weapons *failed to pass*. This was apparently not newsworthy.

America, and probably the world, stands on a precipice. Call you Congresspeople, right now.

The urgent plea of @garymarcus.bsky.social demands rapid action: the US Military, in the hands of fascists, seeks to bend Anthropic to the knee in the aims of incorporating AI into military weaponry. Gary asks us to call our political representatives right now. I just did. Now it's your turn.

A summary of the last decade's news:

2016: the cunts are in charge now
2026: documents reveal that the cunts were always in charge

Calcium spikes know which way the wind blows!

LLMs should be a private cognitive tool, like a calculator, which is not currently possible under our existing model of corporate AI. Crucially, they do not think and have no agency, again in the same way as a calculator

Broader engineering principles than those most of us are familiar with, for sure!

Reverse Engineering of Biological Complexity Advanced technologies and biology have extremely different physical implementations, but they are far more alike in systems-level organization than is widely appreciated. Convergent evolution in both ...

No! It's the other way around. Engineering principles *generate* complex systems:

What’s Wrong with Political Philosophy? Learning from Bernard Williams and Judith Shklar Podcast Episode · Past Present Future · 11 February · 1h 9m

Podcast recommendation: I had never heard of Judith Shklar before, but her idea that hypocrisy weighs against cruelty couldn't be more relevant to our current politics. Depth of discussion is a nice antidote to the rising tide of bs too... podcasts.apple.com/gb/podcast/p...

Not just a gut feeling: It is indeed harder to find reviewers....

My book is now published! 🌏🎶🧪

You can download it for free at academic.oup.com/book/62353 - I’d be grateful if you do!
I also published an accessible summary with audio/video today in @nature.com: www.nature.com/articles/d41...
Try reading that first, then give the whole book a read if you like it!

that's because it was the same country back then... and we're still trying to get rid of them

this is simply because spiritual energy cannot be localised to a unique source

If you use peer review for your own work but refuse to contribute to it yourself then you know what you are: we all have one.
