Here is video of 1st lecture at College de France on Biological computation 😊. I defend the necessity to access Algorithmic & Computational levels of analysis in cell & dev. biol. proposed by David Marr in neuroscience. Logic & Function matter 🤩. Video: tinyurl.com/55yejk5f

Visiting Duke Univ. yesterday. What a treat to be hosted by Akankshi Munjal (former PhD std) 🤩 and spending time with fantastic trainees & wonderful faculty, such as Stefano di Talia. Many thanks for the invitation 🙏🏼. A place full of talent & energy.

Many thanks Nicoletta Petridou @petridou_ni from @embl Heidelberg for visiting us @centuri_ls and giving a truly exciting talk on cell division timing and phase transition during embryogenesis 🤩! Developmental biology is really cool 😎

Cell biologist Mark Terasaki will give US$25 million of his own money to preserve the legacy of a pioneering scientific institute in Woods Hole, Massachusetts. go.nature.com/428hX53

Here is the announcement of a Symposium at College de France 26 June on Information Flow & Computation in Biological systems. Great line of speakers on variety of topics from embryogenesis to neuroscience, immunology & microbiology. Free entrance, come if in Paris end of June 🤩

5.5 years and two babies later, my postdoctoral work is finally out in Cell today! So very grateful to everyone who made this possible. Nuclear envelope budding enables export of large transcripts in muscle... sciencedirect.com/science/ar…

📢Preprint: Positional information (PI) and information flows in dynamic tissues. Our mathematical framework quantifies, from data, how the coupled stochastic dynamics of cell positions and properties preserve, degrade and generate PI. @axplum biorxiv.org/content/10.64898…

A true computational tour de force by Eric Neiva during his Marie Skłodowska-Curie postdoctoral fellowship in the team, now published in Journal Computational Physics: urlr.me/AuzK86 Congratulations, Eric! @CNRSbiologie Grateful to @EU_Commission for funding support

We're in this week's Nature! We propose a model of how a cell learns by running an evolutionary algorithm: exploring different gene-regulatory combinations and using feedback responses to stabilize those combinations that reduce stress levels. Full text: nature.com/articles/s41586-0…

Wonderful visit at the university of St Andrews, beautiful campus and city, in the foot steps of d’Arcy Thompson 🤩. Thank you Marcus Bischoff for the invitation, and the great discussions with you and your colleagues, especially Jochen Kursawe.

What is this bird spotted in Marseille?

🚨Why can’t mammals regenerate limbs like frog tadpoles or salamanders? In our new paper in @ScienceMagazine, we show that species-specific oxygen sensing acts as a gatekeeper for initiating limb regeneration 🐭🐸 🔗 science.org/doi/10.1126/scie… #EvoDevo

This was a terrific talk. Thank you for visiting us in Marseille. 🤩🙏🏼

The mistral was very strong yesterday in Marseille… this iconic pine tree near our home, so majestic that the street was built around it, is a sad victim 😢. No human casualty and the house was left intact…

New piece on the mechanics of squamous epithelial shape transition highlighting the role of tensile forces, force transmission by Dumpy & elastic resistance by the ECM in the developing wing. Terrific work from Stefan Harmansa with Alex Erlich🍾👏: tinyurl.com/2p58b3w3

Le 24 mars 1529, François Ier crée une institution pour une seule raison : la Sorbonne refuse d'enseigner le grec et l'hébreu. Les théologiens considèrent que le latin suffit. Tout ce qui vient de l'Antiquité grecque les effraie. François Ier ne négocie pas. Il nomme deux professeurs, les paie sur ses deniers, et leur donne une mission : enseigner ce que la Sorbonne refuse d'enseigner. Gratuitement. À tout le monde. La Sorbonne est furieuse. Elle tente de faire interdire les cours. Elle échoue. Deux chaires deviennent douze. Le grec, l'hébreu, les mathématiques, la médecine, la philosophie. L'institution s'appelle d'abord le Collège des lecteurs royaux. Aujourd'hui, c'est le Collège de France. Ses cours sont toujours gratuits. Toujours ouverts à tous. Sans inscription, sans diplôme, sans condition. Près de cinq siècles plus tard, rien n'a changé. C'est l'un des derniers endroits en France où le savoir n'a pas de prix.

Visibility in Academia, like in the world, is not fixed; it is produced. This piece “What Cell Biology Reveals About Academia” is a reminder that everyone has the potential to be either seen or unseen.    sciencepolitics.org/2026/03/…

I really enjoyed a lot visiting @ISTAustria, discussing intensely many interesting problems with the students and posdocs all day long 🤓, and for giving a talk. Thank you 🙏🏼 Edouard Hannezo for the invitation and for the very nice dinner with Gasper Tkacik 🤩
