Congratulations to superstar and awesome colleague Gaëlle Letort @gaellel.bsky.social, bioimage analyst extraordinaire for THE CRYSTAL MEDAL OF THE CNRS 2026!!! 🥳🎉🕺🦄🥳 We work with amazing people www.insb.cnrs.fr/fr/personne/...

i knew from the drawing style it was from @tabdanov.bsky.social i look forward to read it further since his work is always thoughtfull and inspiring

Dynein-microtubule forces drive nucleokinesis and transmigration in T cells www.biorxiv.org/content/10.6...

Fabulous work in which Martial Balland and his colleagues revealed the information hidden in fluctuations rather than mean values.

Nice paper from Ruppel et al. in @natphys.nature.com www.nature.com/articles/s41...

Thanks Focal Plane for the invitation to share not only some images but also the scientific motivations behind this crazy project.

Bringing together science & art, @manuelthery.bsky.social & the CytoMorpho lab describe their project on how cells adapt their shape to their environment using the Musée d’Orsay as their template! The full performance was presented over two nights at the museum earlier this year. #sciart #cellbio

Is there a size limit for cells ? How can cells replicate inside the architecture of their environment? Why do cells self-destroy ? This 15-minute movie vimeo.com/1173229237 shows our 2026 edition of the Living Architectures project at the @museeorsay.bsky.social

Well, now that my pipettes have been delivered, I guess I can announce that I am opening my own lab in Rome @UniRomaTre 👩‍🔬👨‍🔬🔬 funded by a FIS3 Starting Grant On active cytoskeleton stuff, of course !

"microtubule feeding tentacles"!

Scott Coyle@cellraiser.bsky.social · 9mo ago

Cellular structure self-organizes through an interplay between internal mechanisms and external cues. The single-celled suctorian P. collini builds a trap structure to capture large prey using microtubule feeding tentacles, creating feedback between cell morphology and prey availability.

gaming is serious. yes i'm serious.

When new biology also lead to new physics ! Active phase separation ! This is so biology: spending energy to keep things organized. I love it !

Alfredo Sciortino@asciortino.bsky.social · 4mo ago

New preprint out: arxiv.org/pdf/2604.01057 Together with JF Joanny and Sudipta, we introduce a "new" kind of active phase separation inspired by experiments with motors and microtubules and based on transport of species along a polar "pump"! @manuelthery.bsky.social @lblanchoin.bsky.social

#JNeurosci: In this work, Tumminia, Mezache, @christlet.bsky.social et al. have developed a new method to induce the formation of synapses along axons directly on the glass coverslip rather than in contact with another neuron. https://doi.org/10.1523/JNEUROSCI.1741-24.2026

The new release of #BigVolumeBrowser (0.1.0) finally adds animation render functionality to it, plus some other navigation improvements and bug fixes. Here is a movie I've made for the microtubule network (via ExM) in different cell types. Contact me if you want it for educational/research purposes.

Since #durotaxis was described >25 years ago, most studies report cells migrating from soft → stiff New work from my team at @ub.edu (in collaboration with D. Odde's lab) suggests we may have been missing the point all along... 🔥 Check out our new preprint here 👇 www.biorxiv.org/content/10.6...

Au Musée d’Orsay, des chercheurs ont transformé des images de cellules observées au microscope en une performance visuelle monumentale. Mais comment fait-on pour projeter des filaments minuscules à l’échelle d’une nef ? Et quels secrets ces images révèlent-elles sur l’organisation du vivant ?

Motor activity of nonmuscle myosin 2A is a key component of bipolar filament turnover in cells www.biorxiv.org/content/10.6...

www.biorxiv.org/content/10.6... Amazing work by Kris and gang! For the first time we have been able to image division ring components live in Sulfolobus. And guess what - CdvA is asymmetrically inherited.

Our results challenge the prevailing model that avidity necessarily leads to mechanically robust linkages; instead, we show how mechanosensitivity can arise as an intrinsic, nonequilibrium property of multivalency. 10/13

Here it is ! the discovery of a self-replicating RNA sequence ! Congratulations to all the authors ! it sounds like a major breakthrough in our understanding of the origin of life.

Edoardo Gianni@edogia.bsky.social · 6mo ago

We took a leap of faith and started a search for shorter polymerases in random RNA sequence pools. We found three ribozymes, but one really stood out of the pack for its activity and variety of sequences it could copy. We named it “QT45”, as it is Quite Tiny and only 45 nucleotides long. 4/n

This weekend we projected cells and filaments on the roof of the @museeorsay.bsky.social in Paris, then we contracted it with a pinch of myosin. And it was fabulous! Grateful to have been part of this art/science project & thx to @manuelthery.bsky.social @lblanchoin.bsky.social & the CytoMorphoLab

A few seconds of eternity: From microscope to museum❣️ It was truly delightful to be part of this project, celebrating life as a continuous dance of creation, collapse, and renewal. 🔄 Kudos to @manuelthery.bsky.social @lblanchoin.bsky.social #cytomorpholab members, and @museeorsay.bsky.social
