🧵 Excited to share our latest preprint on bioRxiv: "Actin Dynamics Sustain Spatial Gradients of Membrane Tension in Adherent Cells"! 🚀🧬 In this thread, we dive into the fascinating world of membranes biorxiv.org/content/10.110… #CellBiology #Biophysics 1/12
Team bleb!! Meeting each other for the first time has been the high of ASCB meeting.
Did you know there are more than bilayer #membranes in nature? Meet the #archaeal monolayer and its surprising mechanical properties! New #preprint! (1/7)
Next week the Biology Club season starts! You will be able to know the research that some postdocs are doing! You are all invited to come! First one we have the new assistant professor @JoanitoLiberti 😊
Another great opportunity for an assistant professorship in our department. Please check the link for more information and spread the word! nature.com/naturecareers/…
10/ To conclude, I would like to highlight the recent work of @juanmagararc et al which, among other experiments, reproduced using Flipper-TR the seminal work done in the Keren lab doi.org/10.1016/j.bpj.…

All what you wanted to know about using flipper probes @spirochrome @matile_group for cell biology and didn’t dare asking is in: rdcu.be/dSmET Thanks to all co-authors and colleagues, thanks to @CRoffay & @vincent81196538 for their great work!
One of my hobbies = watercolor doodles. Here are some fun amoeba morphologies!

what's the funniest tiktok video you've ever seen?
Looking for a summer read?🏖️🌞📄 You're in luck 😂. Our paper on optogenetic leader cells is out @NaturePhysics. We found a force-velocity relation for collective cell migration. Experiments by @LeoneRossetti, theory by @ricardalert. @IBECBarcelona rdcu.be/dQDmM
Our preprint was featured today in @prelights @Co_Biologists. Thank you @SVibha1 for the interesting questions of the mini-interview and the summary you made! @RouxLab @pauguillamat @CaterinaTomba @Colom_D @Aumeier_Lab @Gio_Dangel0 @Liz_Hinde_ prelights.biologists.com/highlights/act…
"Flipper-TR reveals the secrets behind membrane tension gradients."... Check out my latest @preLights post 👇covering the latest @biorxivpreprint from the team of @RouxLab with the first author's response @juanmagararc. prelights.biologists.com/highlights/act… .
Ok, here starts a little tweetorial on everything you should know on 'Gamma Correction" and why it matters...
Just realized how misunderstood and under-utilized gamma correction is in microscopy. Let me state this here provocatively, get some comments and then I will explain what I mean and why it should be used or at least considered every time we publish microscopy images... 😉
How do you go leaflet by leaflet and visualise membrane order specifically in the inner leaflet of the plasma membrane? Read along to find out!! We are very excited to present our lab’s latest preprint, going from the inner leaflet all the way to cell physiology! 🧫🧫🔬🔬
