Predatory aggression evolved through adaptations to noradrenergic circuits - Nature
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...
www.nature.com
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. 👇
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 :

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.

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)

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.
