Go Alex!!

I am beyond excited to announce that the Bisson Lab has a new home!!! Starting January 2026, I will join the Biology Department at Indiana University Bloomington as Associate Professor with tenure. I am actively recruiting scientists across all levels. More in our website: bissonlab.com/join [1/4]

🚨 POSTDOC OPENING 🚨 NIH-funded Bio-Fluid Mechanics Postdoc in my lab @univmiami.bsky.social Hofstenia miamia | cilia-driven flows | behavior & neuroscience Collab w/ Mansi Srivastava @harvard.edu 🕒 Start: Jan–Feb 2026 ⏳ 1 yr, renewable | Email me ASAP! #Postdoc #Biophysics #FluidDynamics

Can biological tissues "learn"? Our new preprint shows that epithelial tissues exhibit emergent behaviors akin to unsupervised learning. Local tension remodeling allows cell networks to store long-range memory and program global elasticity properties. Read more here: www.biorxiv.org/content/10.6...

How does a macrophage decide to eat or simply nibble? Check out our latest paper! You can also read this nice review. Congrats Caitlin for leading this amazing work! www.nature.com/articles/s41... www.nature.com/articles/s41...

The Reck-Peterson lab at Weill Cornell Medicine is seeking a technician or staff scientist to work on Aspergillus projects. Broad background in fungal biology and techniques required. Bioinformatics skills preferred. Find out more at: reckpetersonlab.org.

📢 Deadline approaching fast 📢 to submit an abstract for the great cytoskeleton extravaganza!

#LivingArchitectures We put cells and cytoskeleton filaments on the architecture of the musée d'Orsay. www.musee-orsay.fr/fr/agenda/ev... Scientists of the #CytoMorphoLab adapted their protocols to illustrate the questions that keep them awake at night. -> Two shows on the 24th and 25th of January.

This alternative view of “condensate” biogenesis is compatible with everything that LLPS claims for itself, including the apparent liquid-like behavior that people a bit ignorant of dynamics find so exciting. I explained this here www.embopress.org/doi/full/10....

Any protein crystallographer will tell you that almost any concentrated pure protein in isolation in a simple buffer can be made to phase separate in vitro. It’s an artefact.

SAVE THE DATE! Stoked to organize the 2026 Santa Cruz Developmental Biology Meeting with @rashmi-priya.bsky.social, @lowelab.bsky.social, and Shelbi Russell. Come learn about Biomedicine, Biomechanics, and the Biosphere, August 24-28, 2026. Registration dates, etc., coming soon! Please RT

So cool! Work from cell bio colleague Dorothy Lerit's lab @lablerit.bsky.social, featured in MBoC!

Ten years ago, I saw a paper with some data that has bothered me ever since: B cells in a 0-100 ng/mL gradient of CCL19 are attracted to CCL19, but B cells in 0-500 ng/mL are repelled (see movie, ignoring the big clusters for now!). Why? Here's our model! doi.org/10.1101/2025...

Just out! Our work on active transport in epithelial tissues. Congrats to Huiqiong Wu, Greg Arkowitz and Ranjith Chilupuri in collaboration with C. Duclut and J. Prost! PNAS www.pnas.org/doi/10.1073/...

While this does not excuse his other actions, for me it does illustrate the complexity of some human beings who can be truly dreadful in many ways and, yet, make some surprising and important positive contributions. 40/41

Somehow I missed this tentative but important news -- extension of the NIGMS MIRA (R35) mechanism simpler.grants.gov/opportunity/...

My lab @mpi-muenster.bsky.social is looking for a computational biologist with a passion for imaging and spatial biology. A staff scientist position with long-term perspective! Apply and spread the word 🙏 jobs.mpi-muenster.mpg.de/jobposting/0...

How do cells keep their #actin “highways” stable?🚦 Our paper @PLOS Genetics reveals surprising teamwork (and backup plans!) between tropomyosin isoforms in yeast. #imaging #cytoskeleton #celldivision This work was brilliantly led by @anubhavdhar.bsky.social @bagyasree.bsky.social t.co/RvUrzad5tL

Our latest preprint on the role of the Arp2/3 complex in mitotic entry is now available @biorxiv. This work was done by Dhanya Kalathil, a very talented postdoc in my lab. The story started in 2019 when we were investigating the role of branched actin in cytokinesis. 1/

Just started our @bcube-tud.bsky.social - organized Engineering Life 2025 #25EngLife conference in #Dresden! Excited to have everybody around!
