Yesterday night in Paris. Looks like calcium pulses.

Coupes drastiques du budget de la recherche + durcissement des règles d’attribution des financements ANR «Allez à l’ERC!» qu’ils disent, mais l’ERC saturée prend des mesures pour limiter les candidatures #deadend#recherchefrançaise Une petition semble vaine mais il faut commencer quelque part 👉

When reality surpasses fiction! Top: fictional forecast for August 2050, broadcast by French TV in 2014 to warn about the consequences of global warming. Bottom: Real French forecast for yesterday, June 22, 2026.

Congrat for the all awardees (and sorry for those who didn't get it). Very few awardees from France this year (specially in biology), a result of long term under-investment ? (The less you put in...the less you get).

Applications are open for the international course “Developmental Biology” organized by the Institut Curie in partnership with @sorbonne-universite.fr 📅 Oct. 19–28, 2026 (Paris) ⏳ Jul. 19 & Sept. 18 🔗 training.institut-curie.org/courses/developmental-biology-2026

🥉 Third Prize Winner! 🥉 Congrats to PhD student @anthonyrabate.bsky.social (Université Lyon 1) for this stunning shot, "A tulip field in the drosophila testis"! 🌷 These are young elongating spermatids captured via expansion microscopy. 🔬✨ #FluorescenceFriday #Cilia2027

How ancient are the building blocks of animal sensory systems? Key components of animal sensory systems evolved before animals. We find that choanoflagellates possess diverse & spatially segregated TRP channels, pointing to ancient origins of sensory specialization. doi.org/10.64898/202...

Aggregation in Ministeria induced by bacteria, plus increased mating inside the aggregates. This is really cool! Congrats @multicellgenome.bsky.social and team.

📢 We are looking for a Junior Group Leader to join us at @institutcurie.bsky.social! Having joined the department just over a year ago, I can honestly say that it is an exceptionally stimulating and supportive scientific environment, filled with outstanding colleagues — all in the heart of Paris.

"Humbled to receive this recognition. This belongs as much to my team, my family, & to my home, Palestine: the people, the place, the joyful stubbornness to enjoy life." Cheers buddy @gautamdey.bsky.social Thx to my mentors @sophiemartinlab.bsky.social, @paveltomancak.bsky.social, & Pierre Gönczy.

Congratulations to Gautam Dey (EMBL) and Omaya Dudin (University of Geneva) for being awarded the EMBO Gold Medal 2026 in recognition of their outstanding contributions to the #LifeSciences in Europe! 🧪 https://www.embo.org/press-releases/embo-gold-medal-2026-awarded-to-gautam-dey-and-omaya-dudin/

🎓💙 Congrats to @Yaëlle Wormser, winner of the 2026 French final of “My Thesis in 180 Seconds” (MT180)! 🏆 In 3 minutes, she made accessible a complex study on an enzyme essential to the bacterium that causes tuberculosis with clarity & passion. 👏 #MT180

New preprint! In an fun collaboration with @imaeso.bsky.social and @mirimiam.bsky.social led by Manu F-M, we set to explore the potential adaptation of transposable elements 👾 to host adenine DNA methylation by recruiting prokaryotic DAM methyltransferases: www.biorxiv.org/content/10.6.... 1/6

New preprint! Cell division has to happen at the right place but how Archaea pick that place is unknown. We now identified a three-protein system, Dip, that positions the divisome at midcell in H. volcanii and is broadly conserved across Archaea. A thread 🧵 www.biorxiv.org/content/10.6...

"Complex" multicellularity is often obligate. But why? Why couldn't an animal retain the option to live as a free-living, reproducing protist sometimes? Wouldn't this extra option make life better, more flexible? Answer: this wouldn't be stable. Read below for a population-genetic reason why ⬇️

And now it's out! Happy that PNAS selected for the cover this SEM image snapped by @samjlord.bsky.social, one of the most evocative visualizations of Euplotes that I have ever encountered. www.pnas.org/doi/10.1073/... Stay tuned for what is shaping up to be some fascinating follow-up in the lab...

Back happy but exhausted from our first lab retreat in Carry-le-Rouet- amazing science discussions, fieldwork, some disputable pétanque, and the discovery of some local choanos ❤️ As a bonus, learning about Trichoplax by our local guest A. Pasini. Thanks to @embo YIP for providing all the funding

Any idea of what is this? In the sky above avignon, FR.

These images show live embryos of animals (jellyfish, crustacean, worm, sea urchin, sea squirt, beetle) and one of animals closest single-celled relatives. They were captured taking advantage of fluorescent proteins localised on the outer membrane of cells, allowing us to observe cell outlines. 1/9

This year, the annual symposium of my Chaire @college-de-france.fr will be on The Evolution of Developmental Mechanisms. An impressive lineup of speakers and weirds animals, including humans. Free entrance and coffee breaks. Come, have a seat, relax and enjoy the best possible basic science🤘RT🙏

Drosophila border cells are beautiful to watch… but far from easy to image. Kudos to the brave and skilled @vitoryang.bsky.social, who took on the challenge of establishing border cell migration imaging in the lab! His movies are astonishing, and now our first-ever study on #cell #migration is out!

Orban concedes defeat. The support of Trump, Vance, Putin, Lavrov, Weidel, Milei, Le Pen, Fico, Babis and many others could not overcome Hungarian anger at a stagnant, corrupt regime www.theguardian.com/world/live/2...

Had a lot of fun at the @embo.org cytoskeleton forum @sorbonne-universite.fr this week! As a bonus, got to discover the view from the tour de Jussieu (which is very nice, as from it, you don’t see the tour de Jussieu). Kudos to organizers @romet-jegou-lab.bsky.social @echardlab-pasteur.bsky.social
