Belle réussite pour la 2e journée de médiation scientifique SBCF–SFBD à Ivry-sur-Seine !

Notre nouvelle expo « Cell beau la vie » a émerveillé les enfants. Foldscopes, observation et dessin de cellules : les cellules étaient à l’honneur et ont conquis élèves et enseignants 🔬

Merci à tou·te·s 👏

A fantastic day of outreach in Ivry with 43 classes, 1075 kids and 47 scientists from the @sfbd.bsky.social and @sbcf.bsky.social. Thanks: Mairie of Ivry, @drosopachea.bsky.social Maeva Eglantine and Stéphanie for organizing! And many participants @antoinezalc.bsky.social @michaelrera.bsky.social +

Our study reveals that a this novel asymmetry has evolved through the co-option of a pre-existing tissue remodeling process. Tissue rotation represents a previously unreported mechanism, through which a bilateral organ can acquire a left-right size asymmetry.

We wondered how left-right asymmetric structure evolved and we focused on the unique asymmetric genitalia of male D. pachea...

As several people reached out after the deadline was passed, we have reopened the inscriptions for this fantastic meeting until Feb 10. There are limited spaces left though, so please sign up ASAP. If the seats are all gone, we will close the inscription!

A switch to non-proliferative growth sustains Drosophila wing development during the early pupal stage Using precise tissue volume quantification, El Marzkioui, Gaugué, et al. show that wing primordia continue to grow during the early pupal stage, a phase of increased cell volume driven by insulin/IGF ...

Our new paper is out in @currentbiology.bsky.social! Using 3D reconstructions and volume measurements in Drosophila wing primordia, we show that growth can be uncoupled from cell proliferation and uncover a new time window for growth arrest.

Automorphy as a self-organizing DPP-dependent process that translates patterns into mechanical programs during Drosophila embryogenesis Automorphy gets the morph into the morphogen.

My PhD work is out in Science Advances! We show how DPP drives tissue morphogenesis by encoding local mechanical programs iteratively, unraveling a self-organizing mechanism linking morphogen gradients to tissue dynamics.

Proud to shine bright like radium with @j-delpierre.bsky.social and Fabian from @ybellaichelab.bsky.social, and all the colleagues and friends from @institutcurie.bsky.social, @pasteur.fr, @institutimagine.bsky.social, @institutcochin.bsky.social and @crcordeliers.bsky.social

Thanks to all the volunteers and partners who made this possible! Including @sfbd.bsky.social, @institutcurie.bsky.social and the city of Ivry-sur-Seine.

We have now 5 species sheets: Drosophila, nematode, zebrafish, arabidopsis and bombyx. Available in French and English, and soon in Greek.

This month marks the 3-year anniversary of En Quête de Bio outreach launch, created with @bardinlab.bsky.social and the support of the @sfbd.bsky.social !

By the end of the week, we'll have passed the 4,500-child milestone, done it in 16 cities, with the help of 72 volunteers!

We currently have a call for support that has gone out to European labs, to support FlyBase-UK. We are asking our colleagues from labs in the US and other countries to wait for a similar call to them that will go out in the near future, to support the US sites. We thank you for your patience.

We are deeply grateful for her visit, her passionate commitment to the fight against cancer, and her support for Institut Curie! 🙏

Ready to flight back to Paris after amazing time in San Diego and at #Dros25! Thanks to all the the @genetics-gsa.bsky.social organizers for this fantastic meeting! Glad to met some old friends and new ones!

Proud of our postdoc @drosopachea.bsky.social Bénédicte Lefèvre for her nice talk at #Dros25!

Hi #Dros25! I put some card games from our outreach Biology Quest on the origami table! Help yourself! We still have some with us to spare so contact me or @bardinlab.bsky.social if you want one!
