Many thanks to @nkonst4.bsky.social and the @ijmonod.bsky.social for the invitation and to everyone I met on the day for the engaging a discussions.

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 🧠🪱🔬🧪

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. 👇

How does evolution turn a harmless bacterial feeder into an active predator? Our new study led by @marianneroca.bsky.social and published in @pnas.org explores how sensory systems were rewired to enable prey detection and predatory behaviour in nematodes. www.pnas.org/doi/10.1073/... 🧵below!

it is out! if you like behaviour or nematodes or genes or neuronal circuits or evolution or machine learning or all of the above don't hesitate to have a look.

Why do some worms graze on bacteria while others hunt and kill? Our study, published today in Nature, reveals how predatory aggression evolved in nematodes. Led by @gunizgozeeren.bsky.social and @leoboeger.bsky.social across the @jameslightfoot.bsky.social and @monikakscholz.bsky.social labs.

That is an interesting map in severals regards but I am not sure if it shows where we like to share science the most 🧪or where we like to hang up in pub the most 🍻 ! If you like both hurry to take your ticket, only one week before it start ! here is the link for Germany : pintofscience.de

Have you ever wondered what is on the surface of a #nematode like #Celegans? …it turns out they are surprisingly greasy little critters and covered in many different lipids. To read more about this, check out the excellent paper from the Chauhan lab which we were very happy to be a small part of.
