Peter Hegemann and Georg Nagel – awarded the 2026 medicine prize – discovered a remarkable protein, channelrhodopsin, in a single-celled alga. Hegemann wondered how Chlamydomonas, a single-celled alga, is able to swim towards a light source.

For two weeks, our entire lab is dropping everything to focus on one mission: deploying @embl.org's Advanced Mobile Laboratory to cultivate microbial eukaryotes from Alpine ecosystems. Our dream? Isolating new #Ichthyosporeans never cultured before. Let's see what we find. 🔬🏔️

Must admit, ever since I was a kid, I’ve dreamt of seeing microscopy images of #protists in @lemonde.fr Today, protists are everywhere, and several images were taken by the team. And seeing #ichthyosporeans there too?! 🥹 One step closer to showcasing the beauty of the invisible microbial world. 🔬✨

Together, our results show that the key hallmarks of epithelial cell extrusion are evolutionarily ancient, predating the last common ancestor of sea anemones, flies, and vertebrates🪼🪸✨ 5/5

Inés Fournon Berodia @inesfournon.bsky.social · 16/12/2025
Finally we found active TOR-signalling within rosettes and late apoptotic extruding cells to be phagocytosed by neighbouring rosette cells suggesting a link between cell extrusion and nutrient recycling ♻️ 4/5

Inés Fournon Berodia @inesfournon.bsky.social · 16/12/2025
We also developed an image-based machine learning pipeline 🤖 for automated cell segmentation and rosette ID using Cellpose as the basis. With this we found that extrusion density increases and epidermal cell density decreases during starvation 3/5

Inés Fournon Berodia @inesfournon.bsky.social · 16/12/2025
We also showed conserved active ERK signalling in the rosette cells and confirmed the apoptotic nature of the extruding cells. As previously studied in flies🪰 and mammals 🧫 2/5

It reads "Meet the sea anemone Nematostella vectensis" and shows pictures of pink sea anemones half-buried in sand. Ruth Styfhals, a young woman wearing a green sweater, presents a slide on a screen in front of an audience. The audience is seen from behind at the forefront of the picture. The slide reads "Ctenophores: the oldest animals?" on a bright blue background.
