Sad to hear that Margaret Boden, pioneer in cognitive science and artificial intelligence, has passed away. Just a few days ago, someone reactivated the post below. I warmly recommend watching the video. Thank you Margaret for founding and shaping our field. www.sussex.ac.uk/broadcast/re...

URGENT: FlyBase has lost practically all its funding overnight; even user fees are tied up in denied grant funding. 🤬🤯 Any lab using @flybase.bsky.social please donate using the link in post below. This incredible community, on whose backs our #Drosophila labs depend, can't be left out to dry.

It took us many years to improve idtracker.ai in both accuracy and tracking time. Here it is.

Choose Science. Choose Europe. A new Marie Skłodowska-Curie Actions Postdoctoral Fellowships 2025 call is now open. With a budget of €404.3 million, it will support around 1,650 researchers from Europe and beyond. Apply by 10 September → europa.eu/!fBTMgF

We (mostly @adammarblestone.bsky.social and Mary with the help of the amazing scientists in our network) made a map of “fundamental development” gaps in science and technology. Go explore gap-map.org.

Had to happen at some point: today, the o1 model solved in one go the PhD thesis of one of the students in the lab. Shall we add the model as a coauthor? Shall I stop having students or shall we work on more complex problems?

Just found this. You pin this post below and you get a feed of only papers from your following. Worth a try.

How can randomness be a source of living order? Can physics explain how an embryo emerges out of chaos? In this new paper in Science, Bernat Corominas-Murtra, @ehannezo.bsky.social & cols. show how embryos solve their own Rubik’s cube ist.ac.at/en/news/from...

Today we report that an engineered skin bacterium, swabbed gently on the head of a mouse, can unleash a potent antibody response against a pathogen. Could lead to topical vaccines that are applied in a cream. @djenetbousbaine.bsky.social led the charge... @natureportfolio.bsky.social 1/55

How can physics define universal laws for computation, from cells and chips to brains? In this @pnas.org Perspective, led by @sfiscience.bsky.social David Wolpert and Jan Korbel, they suggest how Stochastic Thermodynamics can provide the proper framework pnas.org/doi/epub/10....

🔍 AI Researchers: Working on radically new AI frameworks or using unconventional math to rethink AI? 📢 Please send us names (incl. self-nominations!) for speakers at the New Math Approaches to AI meeting, Feb 3-4, 2025, at Champalimaud Foundation in Lisbon 🇵🇹. Let’s 🚀 push AI mathematics forward!

I recently went to a talk by Tom Baden (@neurofishh.bsky.social). One of the best I've ever seen. It's a radical reinterpretation of what color vision was initially for. And during questions it covered the roles of the green cone and the UV cones (yep, plural) in mouse vision. youtu.be/gzfiUZ2_5pc
