Extraordinary ‘Gallerie de l’Evolution’ in Paris 🇫🇷. Public funding to explain Evolution to families, with kids running around... An act of resistance🤘🙏🤛🏼

'Lnp' name was refused by an imperialist US nomenclature committee. We thus named it 'Limb, Neural and 'P' (I cannot remember...) LNP, aka Lunapark, which was then accepted 🤓. THIS was ridiculous, not the name itself, which exactly tells what genetics is: an amusement park- @cahirokane.bsky.social

It was called Lunapark since at that time I was biking through an amusement park every morning. Close to HoxD. The first gene to show non-functional enhancer sharing due to its presence within a large 'regulatory landscape' (as defined in this Spitz et al. paper). 1/2

Very sad news. Gail Martin (1944-2026) was a figure in developmental biology. She pioneered the field of ES cells. A great colleague, a friend and a lovely person.

To those who gonna teach @college-de-france.fr, we salute you🔥

Départ à la retraite de #Champollion. La cour d'honneur du @college-de-france.fr est un peu triste 😢 #EtCeFutTout

Assises de génétique humaine et médicale dans la grande salle Louis Lumière du palais des festivals de Cannes🤘 #Epoustouflant! #RobertoBenigni #DoubleHelix

List of new NCCRs is out. For the yet to come project in humanities, I suggest a multidisciplinary sociological, psychological and political study to understand why all funding goes to Zurich 🙄 www.sbfi.admin.ch/fr/newnsb/JE...

🙏🏻CoB ! You rock🤘!

This was a super interesting and friendly evening with the ’jeunes chercheurs’ @institutcurie.bsky.social Lot of fun discussions and wonderful (isotope-free) pizzas. Many 🙏 @adic-association.bsky.social, you rock!🤘

A night in Geneva 🎸🎷🥁

Took a therapeutic visit to the very poetic (and anonymous) grave of Alfred Jarry (1873-1907) #CimetiereBagneux. As a last wish, he asked for a toothpick. He, more than any others, anticipated 130 years ago, the current situation. Cornegidouille! 🤘#UbuRoi

La vente de Davos est en route (OK pour moi)

Many congrats to the two 2026 laureates of the Jeantet Prizes!👏💐

Spent the last 5 days to think/write a point by point responses to referees. Over 250 papers, it makes 3.5 years of my career spent in arguing like a weeler-deeler (with various outcomes)🤔🥸

Snowy white everywhere in Paris today. The right time to see the splendid exhibition Pierre Soulages at Luxembourg museum 🙏. An urgency, in fact.

Champollion les pieds dans la neige @college-de-france.fr 🥶

😢 Watch again Le Mépris, master piece from Godard, extraordinary with M. Piccoli in the living room of the Malaparte house, in Capri, with red roses on the table and Faraglioni through the window. Unforgettable. #EtDieuCréaLaFemme #BébésPhoques

Who can identify in the mirror the gentleman taking the pict (with moustache and a Hox-proofed 5 digits hand) ? (@vanderhaeghenp2.bsky.social disqualified).

No pasaran !

..et Champollion prêt au départ, pour une nouvelle jeunesse 👋🏼

Great moments of 2025🙏 With old friends at the #AnneEphrussi @embl.org farewell symposium 🥲

Good morning Geneva! Massif du Mont Blanc, mythical grandes Jorasses🤘
