Our new preprint is up! This is the main postdoc work of @wiesner-t.bsky.social focusing on exocytosis along the axon shaft and its regulation by the sub membrane actin-spectrin scaffold: www.biorxiv.org/content/10.1... Read the thread below for a summary of our findings 🧵1/11

AI in Microscopy: A BioImaging Guide (bioimagingai.janelia.org) is available now! This free, online textbook bridges the gap between tool developers & microscopists + biologists. Whether you’re new to AI or already using it, we hope this book gives you the confidence to apply AI in your research.

Today marks the launch of the PRC (Publish, Review, Curate) Alliance, which includes EMBO’s preprint review platform, Review Commons. 🧪 The Alliance is a joint initiative of COAR and ASAPbio. Learn more: https://reviewcommons.org https://www.publish-review-curate.org/

Amazing high-speed AFM recordings of microtubule lattice collapse and catastrophe. It looks very much like processes in the lattice of crystals (which I believe MTs actually are). pubs.acs.org/ancac3/artic...

Yesterday was a fun ride. A 112-km alleycat bike race with 18 checkpoints between Toulon and Marseille!

On the Vieux Port tonight #racismkills

Interesting new method: network fixation expansion microscopy (nfExM). Uses MeOH/acrolein at -20°C followed by gel embedding also at -20°C. Works well for microtubules, not sure about the mitochondria/Golgi morphology in the figure's examples www.biorxiv.org/content/10.6...

🖤 Remembering Françoise Helmbacher, who led a research team at IBDM (2005–2024), then at Marseille Medical Genetics. A passionate scientist dedicated to studying neuromuscular development and disorders. Thoughts are with her family, friends and colleagues. 🫂 www.insb.cnrs.fr/fr/cnrsinfo/...

#iykyk @roylab-ucsd.bsky.social @franbottanelli.bsky.social @christlet.bsky.social a copy in the wild.

I'm obsessed with these empty clathrin cages people are seeing in neurons, and don't understand why others are not. So I put everything together and wrote a brief review (Current Opinion in Neurobiology, free access for 50 days): www.sciencedirect.com/science/arti...

Back in the streets this afternoon. Peaceful protest and infinite sadness for the victims of the far-right racist attack in Trappes yesterday

I'm BACK

Happy for the image of distinction in this year's Nikon Small World Competition, and congrats to all the winners!

I was lucky to reach Bordeaux with no issue on the cursed line... too lucky! Now the tracks have been damaged by a flood and all trains to come back to Marseille have been canceled for at least one week 😭

The microscope whisperer is live at #SFBS2026!! @christlet.bsky.social

Zhixing Chen @zhixingchen2.bsky.social on stage to tell us about his latest bright, stable and gentle fluorescent probes at #SFBS2026

Registration is open for the 2027 @embo.org Workshop on Cell Polarity and Membrane Dynamics, co-organized with @alexludwig.bsky.social and @dianapinheiro.bsky.social. Join us in May 2027 in Sant Feliu de Guíxols, near Barcelona! meetings.embo.org/event/27-cel... #EMBOCellPolarity

Bravo @erc.europa.eu 🙄

#SFBS2026: Time for @henriqueslab.bsky.social to blow our minds with the stunning suite of approaches his lab developed in less than 10 years: (e)SRRF, DL4Mic, SReD, NanoPyx, VLab4Mic. Starting with the legendary SMLM Eiffel tower! henriqueslab.org

The Franco-Chinese sister cells I made as meeting cover 🇫🇷 🇨🇳

Made it to Bordeaux for the opening of #SFBS2026!

🎸 I made a free, open-source guitar tuner that runs right in your browser: nothing to install. Give it a try on your instrument: laurentperrinet.github.io/guitoune/ #guitar #ukulele #bass #tuner

Just boarded the cursed Marseille-Bordeaux train en route for the Sino-French Bioimaging symposium #SFBS2026 (rb.gy/d4kppk). Will I make it to Bordeaux? When will that happen? It's always an adventure!

From today's student protests in Toulouse, France. *Massive* turnout with people of all ages, from all walks of life. And also quite creative with their placards!

Immune cells don't only interact with the ECM, they also interact with surrounding cells in tissue as they migrate. This video gives me so much joy because there is just so much biology here to be discovered. Sticky cells! Here, immune cells are 🔴, ectodermal cells are ⚪. Happy #FluorescenceFriday

I was like "microscope session" until I read #3

I'd add fuck this fucking hybrid zoom setup in the amphitheater
