A microscale version of the flumes used to study liquids in the laboratory will make it far easier to study nonlinear hydrodynamics. The device consists of a few-atom layer of superfluid helium on a silicon chip, and it could help us better understand climate. 🧪⚛️ physicsworld.com/a/microscale...

New paper from the @rouxlab.bsky.social on Nature Communications! We study how membrane tension is spatially organized in cells. Using the mechanosensitive probe Flipper-TR to visualize tension across the plasma membrane of adherent cells and to dissect the conditions needed for a gradient to happen

Overall, the work shows that tension gradients arise from the combination of actin dynamics and strong cell–substrate adhesion, rather than from migration itself. Link: rdcu.be/eRTQA

📢 Paper alert 📢 Chirality is known to be important for the movement of microorganisms and active matter. In our new paper out today in @natphys.nature.com, we show that chirality is used by malaria parasites to control their motion patterns: doi.org/10.1038/s415... Here comes a 🧵 ... (1/9)

This is happening TODAY at 2:30 UK time! Hope to see many of you there!😊

is there a direct crosstalk between actin and vimentin intermediate filaments? Our work shows that vimentin promotes actin assembly by stabilizing ATP-subunits at the barbed end. Fantastic work done by @lilianpaty.bsky.social with @romet-jegou-lab.bsky.social www.biorxiv.org/content/10.1...

We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji. It ships many new features, detailed below, but that are articulated around the following:

The lab’s first pre-print! We investigated how growth-inducing Erk activity waves are regulated in regenerating zebrafish scales. We discovered that Erk waves are followed by waves of expression of their own inhibitors, as predicted by excitable waves theory. tinyurl.com/26r2cmpj

Why would Mycobacterium shed its surface right after entering a host cell? Host phagocytes rapidly strip its outer layer, releasing components that alert neighbors and trigger defense responses Our preprint is out, curious to hear your take! 👀 www.biorxiv.org/content/10.1...

Quite a busy day on #Bluesky ! Been a while since we have been #preLight -ed ! Discover HAK-Actin if you haven't already ;)

Hi, I’m David Brückner @davidbrueckner.bsky.social. I’ll take you through how cells in a tissue can use information distributed by biochemical gradients to make decisions, and how we can measure such positional information. buff.ly/RFxVeHh

Another season of Stranger things is releasing and we have another season of stranger things happening with Hydra @rouxlab.bsky.social #fluorescencefriday #postdoclife

Maria Tettamanti shows that inhibition of TORC2 by the small amphipath PalmC induces the TORC2-dependent internalization of sterols. Congrats to Maria and all coworkers involved, and to EMBOj for the efficient review process: use review commons! @biology-unige.bsky.social @sciencesunige.bsky.social

Painted tonight instead of sketching and actually pretty pleased. This went from being “the ugliest thing I’ve ever seen and made in my entire life” to “oh, oh, this turned out pretty good!” 😂 I love art. #art #painting #oils
