Our latest paper is out in Nature 🥳 We investigated the underlying neuromodulatory regulation of aggressive behavior in the nematode Pristionchus pacificus 🪱🧠🔬 And we show that novel behaviors can evolve through changes of single neuron function by switches in neuromodulator-receptor expression. 👇

Noradrenergic circuits support and balance aggressive behavioural states in predatory nematodes, distinguish predatory from non-predatory nematode species and are associated with the evolution of comp...

The IL2 neurons are my new favourite neurons in Pristionchus. In our new paper, lead by @marianneroca.bsky.social, we show which sensory modalities are crucial for a predating worm, which all are sensed in the IL2’s. And the IL2’s are sensitive to octopamine, promoting aggression in these worms 🧠🪱🔬🧪

How does a predator sense its prey?
🪱The nematode Pristionchus pacificus preys on other nematodes, but how it detects them in its environment? That is what we have been exploring :

No more work for me this year. Had a lot to do again at the end. But was worth it and fun. I think next year will be cool 🔬🪱🧬
Now, I‘ll be enjoying the break and Christmas🎄and as a starter, I always enjoy the neat little stories ⬇️

Interested in neuromodulation, predatory worms or hidden Markov models? Or the combination of all three? Then come and see my poster (number 21) today in poster session 1 at the #BernsteinConference.

Yesterday’s PhD symposium of the #BernsteinConference was great fun. Today I spent the morning in the Senckenberg museum, what a great exhibition! Too much to look at in 3h, will have to come back.
Now heading to the start of the main conference. Looking forward to a lot of great talks and posters.

Me: this is great, glad to see authors ripped off by AI getting their due.

Me after using the search tool: I am one of these ripped off authors.

Academics, it only takes a minute. Seven of my papers are in this and I had no idea.
There are tons of graphic novels, academic papers, film and TV scripts, & prose novels/nonfiction on the LibGen list Anthropic used.

As settlement approaches, make it easy for the class action lawyers to contact you! Here’s how

New preprint: Scientists, how many times has this happened to you? You collect all kinds of data from a camera or microscope. But then you are faced with an analysis pipeline that threatens to take 100x longer than collecting the data did!

The funds are approved! We're hiring a postdoc to build a CRISPRa toolkit to identify new aging mechanisms in C. elegans.

Guter Artikel! Mit „die anderen sind doch noch viel schlimmer“ kommen wir auch nicht weiter. Auch weil wir uns alle gegenseitig beeinflussen. For better or for worse.

Viele von uns fliegen zu weit und essen zu viel Fleisch. Doch schuld am Klimawandel sind Reiche oder Politiker. Diese Doppelmoral der Mittelschicht-Ökos ist gefährlich.

Are LLMs correlated when they make mistakes? In our new ICML paper, we answer this question using responses of >350 LLMs. We find substantial correlation. On one dataset, LLMs agree on the wrong answer ~2x more than they would at random. 🧵(1/7)

Kudos to @bcmerchant.bsky.social for some absolutely essential reporting from the frontline of AI’s enshittification of our culture (not to mention our software).

Worth the long read.
AI is being used to justify firing workers at major tech companies, leaving those that remain to pick up the pieces.

AI code is being shoveled into crucial Google products, replacing trainers at TikTok, and worse.

This, in tech workers' own words, is how AI is killing jobs in Silicon Valley.

Scientists who study climate don't automatically attribute all changes to human activity. Rather, we carefully investigate every possible natural factor that could explain the planet's warming.

Could these be the real culprits?

The evidence is in--and the answer is NO.
