On met les enfants en cage et on les électrocute pour la #FeteDeLaScience au @grandpalaisrmn.bsky.social par le @palaisdecouverte.bsky.social.

Jochen was a brilliant and visionary scientist who inspired me and so many others. His creativity blew my mind more than once and his generous advice early on in my career was extremely useful. How lucky I feel to have met him.

Former French president Sarkozy guilty of criminal conspiracy in Libyan campaign financing trial – Europe live Nicolas Sarkozy has been found guilty of conspiracy, but innocent of other charges, in case surrounding millions of euros in illegal campaign funding from late Libyan dictator Muammar Gaddafi

Slowly and tediously, even the rich and powerful can be taken down in functional democracies. This is the third conviction for Sarkozy (and his acolytes). This should encourage other democracies in difficult situations to keep hoping for justice to prevail.

Trump Says the U.S. Will Institute $100,000 Fee for Skilled Worker Visas

I was on a H1B visa for part of my postdoc. Also when I started as Assistant Professor. Several of my postdocs where on H1Bs. This new fee will affect more academia than tech or finance companies because there is no way universities can pay that…

Patterned invagination prevents mechanical instability during gastrulation - Nature In Drosophila, the cephalic furrow counteracts mechanical stress as the developing head and the trunk tissues meet, providing evidence for how mechanical forces influence the evolution of morphog...

We had #four interdisciplinary teams, integrating dev-bio, evolution, tissue mechanics, and biophysical modeling, all going full throttle to understand the #CF. Still, it took more than 7 years to publish two papers back-to-back (10/12)

We are all super happy and proud to see our work on the function and evolution of the #cephalic #furrow published in @nature.com. Let me say a few things about the background and history of this work on the #Evolution_of_Morphogenesis (1/12)

How is this possible?

This ant can lay eggs of two different species, birthed by the same mother

Expansion microscopy micrograph of the choanoflagellate Choanoeca flexa, vaguely evocative of a cactus. Red = tubulin, green = actin, blue = DNA

Same with yellow = lipids (BODIPY)

A dream come true: the first expansion microscopy images of C. flexa 🤩 Generated by Mylan & Uzuki who learned from the best (@hiralshah.bsky.social @gautamdey.bsky.social @dudinlab.bsky.social). We will learn so much from these!

🔬 The next international Developmental Biology course, organized by Institut Curie with @sorbonne-universite.fr, will focus on "From stem #cells to #morphogenesis".

📅 Apply by:
• July 20 (3.5 weeks with hands-on workshop)
• Aug 31 (10 days of seminars)

Congratulations Ina! @hubrechtinstitute.bsky.social is lucky to have you!

Congratulations Monica (and CRG)!

Happy to be the next (and 1st female) @crg.eu director. The CRG always stood out to me, for its excellence in understanding life's principles, with implications for health and biodiversity, & its collaborative, open and innovative way of doing science. Thrilled to join its amazing community in 2026!

Had a very productive day @eshre.bsky.social #eshre2025 meeting with the biomedical community! We have a very different way of thinking and questioning the embryo and a lot to learn from each other!

Happy to be elected at the national committee @cnrs.fr
I thank all of those who voted🙏.
I promise to do my best to promote excellence in science through diversity and interdisciplinarity, transparency and discussion with the public.
📣Let me know what you would like to see improved @cnrs.fr📣

Former French President Nicolas Sarkozy stripped of the Legion of Honor The decision to revoke the country's highest distinction was expected since Sarkozy's conviction for graft. President Emmanuel Macron said he was opposed to the move.

It's frustratingly tedious, it's imperfect but it eventually works. Democracy works, even against the most powerful men.

Russian Scientist Released After Four Months in Federal Custody Kseniia Petrova, a Harvard researcher, still faces criminal charges for failing to declare scientific samples she was carrying in her suitcase.

Breaking News: The Harvard researcher detained after failing to declare scientific samples to U.S. customs was freed from federal custody. She still faces criminal charges.

Thanks @currentbiology.bsky.social we need to hear the voice of honest and generous scientists like @dudinlab.bsky.social more often.
Also, if you don't know about @dudinlab.bsky.social amazing science yet, go check it out immediately 🤩!
