Truly chuffed for our fearless food physicists @mpipks.bsky.social + collabs from AT @istaresearch.bsky.social, IT & ES who won this year’s Ig Nobel - the #NobelPrize of hearts❤️for cracking the science of perfect pasta !🍝Kudos to all for intrepidly consuming lots of cheese in the name of science!😋

The Secret to a Smooth Pasta Sauce Wins Ig Nobel Prize

Italian researchers studied how the ingredients of the traditional Roman dish cacio e pepe emulsify into a creamy sauce, winning the 2025 Physics Ig Nobel Prize.

We developed image analysis tools to capture the nematic orientation field of 3D tissue surfaces. Tested on epithelial aggregates, zebrafish hearts, myoblasts on spheres & micro-vessels, we combined soft matter physics with exp. biology.

Very happy that the first article from my postdoc work in the Tomancak lab is now published @PNAS! www.pnas.org/doi/10.1073/.... We studied the self-organization of actin in aggregates made from Hydra cells. Thread below (1/9)

Dreaming of a swimming pool? Bacteria are surrounded by water! Water capillary forces organize bacterial colonies into gas, nematic streams, or droplet states. New paper @natphys.nature.com led by Matt Black and Chenyi Fei, with Ned Wingreen and Josh Shaevitz!

Capillary interactions drive the self-organization of bacterial colonies - Nature Physics

Bacteria tend to live in thin layers of water on surfaces. Now the capillary forces in these layers are shown to help organize the bacteria into dense packs.

Our study on endothelial mechanics made the news! 🤩

Super nice and clear article on our findings and their implications.

Here’s why your blood vessels don’t burst under pressure

Cells lining the blood vessels reorganize their inner structures to handle stressful boosts in pressure.

On cell extrusion in the #intestine!
After 80 years of observations, we finally took a deeper look thanks to 2D #organoids. We report:

3D #forces, #extrusion still only in the villus even without curvature, #lamellipodia generate 3D force.. and more. Have a look!

🚨 Second preprint of the week!

We uncover the multiscale dynamics of active viscoelastic buckling in epithelia.

We harness these mechanical instabilities for synthetic morphogenesis.

New preprint out! We show how cellular nematic order can be harnessed to program tissue-wide force fields and guide 3D shape transformations.

We may not have really squared the circle — but we came close! 😉 In our @NaturePhysics paper w/ @fakhrilab.bsky.social, light-triggered membrane excitability enables programmable shapes — a step toward engineering living matter.
