Isotropic STED resolution (~70 nm) with a single objective using a new type of light modulator. "m-order vortex retarder" sounds like a Star Trek contraption but the images are stunning! arxiv.org/abs/2507.06718

Fantastic Nobel Moment at #worm25 with Victor Ambros and Gary Ruvkun.

Oil form droplets when mixed with alcohol, your monolayers dewet to form spherical aggregates, your friends dancing in a club form a circle, why? I’m @challopeau.bsky.social and I will tell you about the origins and consequences of interfacial tension in tissues.

With a heavy heart I have decided not to attend a meeting in the US this June. I can’t act as if things are normal when science, universities, dissent & truth are all under threat. And I feel I can’t attend when there are scientists who are not able to travel to the US without fear of arrest.

#fluorescenceMonday another nice example of regionalization of #aECM, during development #celegans vulv(a), of one of the Cystein Cradle domain # ECM protein, a familiar shape in Marseille😉 🙏to Sophie Mazzoli, @france-bioimaging.bsky.social platform @ciml.bsky.social & www.excitingworms.eu/SEGiCel/

in a new micropub 🙏 @micropub7n.bsky.social we shows the secretion of the Antimicrobial Peptide nlp-29 in the apical extracellular matrix #aECM upon several aECM damage in #Celegans 🙏Henrik Bringmann @cmcb-tud.bsky.social for the KI strain doi.org/10.17912/mic...

How is extrusion of infected host cells related to ERK (extracellular signal-regulated kinase) activity? Hi, I’m @hundsdorfer.bsky.social from the @effiebastounis.bsky.social lab. Let’s follow the recent development of bacterially-infected cell extrusion & mechanochemical ERK activity waves.

Intriguing #EM observation: in mouse type I hair cells, #SBF shows elongated mitochondria (yellow) apposed to the plasma membrane, a membrane contact site of 10 nm

Our new paper out @plos.org @ciml.bsky.social @centuri-ls.bsky.social Fantastic collaborations 👏Antonina Andreeva #EBI-EMBL, Claire Valotteau @DyNaMo @felix_rico, Andrew Chisholm, Jordan Ward @gotworms.bsky.social, and great discussions with @meera-sundaram.bsky.social dx.plos.org/10.1371/jour...

Interested in doing a sabbatical at EMBL, at one of its 6 sites in Barcelona, Cambridge, Grenoble, Hamburg, Heidelberg or Rome? Funding call with deadline 15 June, decisions in July. www.embl.org/about/info/s...

Excited to share that IBDM (Institut de Biologie du Développement de Marseille) is expanding its research groups this year! A great place for developmental biology and interdisciplinary research located on the beautiful Marseille-Luminy campus! Deadline for applications: March 30th, 2025

Registration for the next GdR AQV days is now open until April 18th. The conference will take place in Sète - May 26th to 28th. aqv-days-2025.sciencesconf.org There are many slots for oral communication. Come and join the French biophysics community!

"exciting to see this key piece of infrastructure really get the attention that it deserves" @katiecorker.bsky.social on the new non-profit that will run bioRxiv and medRxiv www.nature.com/articles/d41...

4 more days to submit your abstract!! Don't miss the opportunity to come to Leuven and enjoy 4 days of #Mechanobiology: 🗣️ 15 amazing keynote speakers 🎤 Oral talks and poster sessions 📷 SciArt contest 🍻 Social activities 👉 Submit by 2nd March!! https://buff.ly/3CH94pW

Despite court order, NIH grants remain frozen. Newly awarded grants, grants with fundable scores, & funds for a new budget cycle of a current project are all *FROZEN*🥶 and not being released. US research is being choked to death & is on life support right now www.motherjones.com/politics/202...

On March 7, let's stand up for science! 🔬✊ In solidarity with Stand Up For Science US (@standupforscience.bsky.social) and in response to threats against scientific institutions, actions will take place in every university city in France. Info & registration 👉 standupforscience.fr

Welcome to the Bluesky account for Stand Up for Science 2025! Keep an eye on this space for updates, event information, and ways to get involved. We can't wait to see everyone #standupforscience2025 on March 7th, both in DC and locations nationwide! #scienceforall #sciencenotsilence

#fluorescencefriday still puzzled how to build such a beautifull periodic pattern #aECM

🔔🧪 I'm deeply saddened by the passing of Michael Sheetz, a true pioneer in #mechanobiology. I'll always cherish our lovely times in NYC, Singapore, Zurich, and Sydney. My heartfelt condolences to his family and friends in this difficult time. So long, Mike 🥺😔

🚨Hyped to share our new article in @natureportfolio.bsky.social! We show that crocodile head scales develop from compressive folding that arises from constrained skin growth 🐊🔬 Really proud of this one - it's cool 😎 Please read & share! 🧪 @genevunige.bsky.social www.nature.com/articles/s41...

How hard do bacteria-eating nematodes bite in order to break the bacterial cell wall? Check out our new paper, led by Jason Casar & collab with Jen Dionne, using pressure sensing beads that change color upon compression (bluetorial coming soon) rdcu.be/d5n7v

👋Hello #mechanobiology community in 🦋! This is the official account of the 10th Edition of the Cell Mech conference! 🔧We will soon announce the invited speaker list! Visit our website, subscribe to the mailing list, and follow us!: cellmech2025.org 😍Join us in Leuven 2025!

#fluorescenceFriday our favorite giant cell secreting abnormal #aECM

today I discovered ribbons and floating ribbons what a beautiful structure #EM www.youtube.com/watch?v=Lv6b...

I just tried that with one of my recent papers... A bit over-enthusiatic and over-selling, but overall absolutely mind-blowing (the full paper is linked below) 1/2🤯: notebooklm.google.com/notebook/63e...

I didn't find a specific mechanotransduction starter pack, so I open one myself😊. There are still a lot of people to be added, but it's late, so please drop me a message or post here to nominate yourself for the Mechanotransduction community. go.bsky.app/2PXf5SC

Pre-announcing the 10th Biennial European CellMech conference organized in Leuven 🇧🇪 from September 30th to October 3rd, 2025. cellmech2025.org Save the date !

I made a start at this, but need more #aECM names! Please suggest some! go.bsky.app/QTi9nHY

Single cells can learn without a brain, but how? Our new preprint from @deeparajan.bsky.social describes a model for habituation in Stentor coeruleus, based on receptor internalization and recycling, along with new experiments inspired by the model. 1/n www.biorxiv.org/content/10.1...

The Company of Biologists will be turning 100 next year! 🥳 To celebrate, we’re holding a conference but, true to @biologists.bsky.social style, it’s not just any old conference - it’ll bring together our wonderful communities and will have a sustainability focus. Join us! youtu.be/yQ_VY86zVtg

fluorescence friday :-)

#aECM (apical extracellular matrix) is a subset of #ECMatrix that is distinct from stromal matrices or basement membranes. Anybody out there studying #mucins #ZPproteins #cuticle #glycocalyx #surfactant or the like? We need to find each other and start talking!

Feels good to be here!
