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.

It’s back! The DBIO Focus Session on Collective Behaviors in Biology returns to #APSMarch #APSSummit26 🎉 Submit your abstract by Oct 23 and join us in Denver! go.aps.org/3I51s36
Invited Speakers: Jasmin Imran Alsous (Flatiron Institute) & Shiladitya Banerjee (Georgia Tech)

Universality in the Mechanical Behavior of Vertex Models for Biological Tissues A systematic comparison of diverse cell packing models reveals shared mechanical rules that govern how tissues stiffen, yield, and reorganize---shedding light on the physical logic behind morphogenesi...

Why do vertex models work so well to predict tissue fluidity/rigidity, even though they are simple and possibly even wrong? A new paper in PRX Life
@prxlife.bsky.social, spearheaded by @sadjadarzash.bsky.social and Ojan Damavandi, suggests universality may explain: journals.aps.org/prxlife/abst...

Excited to share our new paper in PRX Life @prxlife.bsky.social!

We uncover universal viscoelastic behavior in different vertex models of biological tissues, explaining why so many models work so well. Enjoyed working with Ojan (co-first), Liz & Lisa on this!

Would love to be added here!

I’ve been looking for such a list! Could you please add me, as well?

This is a great list! Can I join?

Have you ever wanted to *see* receptor activity in embryos? If so, our new preprint is for you! In it, we showcase a new live-cell biosensor for visualizing receptor tyrosine kinase activity in living embryos – pYtags!
