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!

More info here: www.eqd-bio.org

Pavel Tomancak asks everyone who uses FIJI in the crowd to stand ... and dammit, 90% of the crowd stood. What a testament to the power of such tools. #DROS25

Hey @genetics-gsa.bsky.social #Dros25 attendees! Want to come chat about professional development and/or your career goals? Want to play a round of @bardinlab.bsky.social's Biology Quest or @pged.bsky.social's Share Your Stance? Come visit me in California 3 - if the door's open, I'm in!

Now I can die in peace 🥺

(Thanks @drosopachea.bsky.social for the picture)

A fabulously fun and educational game! I learned about the value of cell death in limb formation 🤩 #Dros25 @genetics-gsa.bsky.social

Thanks Allison! 😊

Come see us to discover our outreach, play games and try to win one of our 50 card decks! More info: www.ead-bio.org

Super happy to discover the breathtaking city of San Diego and looking forward to attending #Dros25! I'll present my work with a talk tomorrow during the Cell Division and Cell Growth session, and we'll be with @bardinlab.bsky.social at the networking event to present our outreach Biology Quest!

A reminder- come and see us Thurs. evening at the Networking session to win one of 50 decks of En Quête de Bio (Biology Quest) cards for you (and your kids!).
www.eqd-bio.org

We will also present at the Networking session on Thurs night 8pm at #Dros25 our side project on primary school outreach with the French Dev Bio Society @sfbd.bsky.social #EnQueteDeBio or "Biology Quest" in English (info at www.eqd-bio.org). Come visit to win one 50 decks of the Dev Bio Card Game!

So happy to be back home in San Diego for #Dros25 for great science!
Come see @drosopachea.bsky.social from our lab speaking in the Thurs 4:30-6pm session on Cell Division and Growth!

Our intership student, Maia, was featured in this article about the #StandUpForScience march!

Parisian scientists are out! @standupforscifr.bsky.social

See you at Jussieu in Paris tomorrow at 1:30 PM! We will march by the Statue of Liberty at Luxembourg Garden, a great symbol of our treasured alliance and shared values! 🧪🗽 @standupforscifr.bsky.social @sufs-paris-rp.bsky.social @standupforscience.bsky.social

thanks to all of you who came for the group picture!

Today, and regarding the terrible situation ongoing, we @standupforscience.bsky.social at the BDD unit of @institutcurie.bsky.social! Let's fight for freedom of academic research!
