Stress propagation in active solids induces spontaneous actuation of floppy modes without exciting vibrational modes Letter: go.aps.org/4aViIjP Focus: go.aps.org/3XdD2K1

Bacterial nanomotors spin at up to 20,000 rpm x.com/i/status/18020…

When in 3D, confinement drives new collective states in epithelial sheets. Glad to see our work with @anne_grapin Marko Popovic Julicher complements this growing body of exciting work

Great collection. I would also add this from the groups of Giorgio Scita, Nir Gov and Ajay Gopinathan science.org/doi/10.1126/sc… which showed clusters of chemotactic cells switching from running to rotating phases

Cell 1: I am going this way. Cell 2: No, come this way with me. Cell 1: Where are we going? Cell 2: No clue, but at least we will be together. Some that wander are lost........ #CellBiology

A belated post: Patrick Noerr successfully defended his dissertation entitled "Mechanical interactions in biological active filaments and networks" earlier this summer. Congratulations Dr. Noerr!  Wish you all the best in your postdoc career at UCSD!

🎉

📢 IgNobel prize for active matter! The physics of drunk worms! 🪱

Monday: check out a Zoom seminar by postdoc Emiliano Perez Ipina on the SLAAM series sites.google.com/view/slaamsemi… - he'll talk about his work on cells interacting with and modifying complex environments

I will be giving the SLAAM Seminar next Monday morning October 7 (10am Pacific time/1pm Eastern) on Zoom. Please attend if you're interested in biomolecular phase separation, transcriptional control and hyperuniformity! More details: sites.google.com/view/slaamsemi…

Registrations are open for the Qlife Quantitative Biology spring school on Cell Dynamics in Developmental System March 3-April 04 2025. Great line of talks, lectures and hands-on practicals on omics, image analysis, modeling and inference: shorturl.at/Ygthh

Thank you APS DSOFT for organizing such a great Panel Session! Lots of great questions - and if anyone is interested feel free to reach out for any further advice

Our article on a long-range mechanism for durotaxis is now published! sciencedirect.com/science/articl… Grad student Subhaya Bose and coworkers introduce elastic dipolar interactions into an active particle model: a cell may sense a stiffness interface from afar without straddling it!

All excited about this invited talk.

It was fun to attend this fantastic workshop on Mechanobiology organized by my good friend and collaborator Xinpeng Xu in Hangzhou, China. The recorded talks are now available

Here’s our latest paper published in Physical Review Letters! DOI:doi.org/10.1103/PhysRe…. We show the F-actin severing protein, cofilin, crosslinks F-actin networks under the acidic condition, and minimizes the penalty of connectivity for rigidity, with mechano-sensitivity.

Congratulations to Subhaya Bose for successfully defending his PhD dissertation tonight. Thanks also to the committee for being very engaged and keeping him on track in the last 5 years.

looking forward to connect with scientific colleagues on the other side! dasbiswas_lab.bsky.social

Stand up for science! Happening this Friday 3/7 - look up for local events near you : standupforscience2025.org most campus nationwide will organize, join if you can, make our voice heard
