How does an elastic line buckle within a curved surface? The answer, by @zhaoshh.bsky.social and @lepuslapis.bsky.social @mpipks.bsky.social @mpi-cbg.de @csbdresden.bsky.social, has now been #published @physrevlett.bsky.social:

New preprint! Do you like ocean waves? We found similar waves on bacterial colonies! We found that this collective behavior, known as rippling, is nothing but surface waves on an active nematic. @princeton.edu @mpipks.bsky.social @ub.edu @icreacommunity.bsky.social

Delighted to announce “Hydrodynamic Approaches to Active Matter: Successes and Future Challenges”, will now take place on 6–10 October 2025 at @mpipks.bsky.social, on the occasion of John Toner’s 71st birthday. We hope you will join us.

* Possible reasons include not having access to Mathematica and predating Riemann (in the non-ecological sense).

Congratulations!
Prof. Igor Herbut (Simon Fraser University) awarded the "Physik-Preis Dresden 2025“

This work explains when new optimal strategies emerge and guides the design of more efficient #quantum technologies.

We welcome @fbrauns.bsky.social as a new group leader @mpipks.bsky.social and @mpi-cbg.de!

Now #published as a Letter @physreve.bsky.social: "Geometry of T1 transitions in epithelia" doi.org/10.1103/kdnb-bxdx

My first single-author paper deploys a silly amount of Olympiad geometry on a fundamental biophysics problem, summarised in the attached thread!

A new call for the ELBE Visiting faculty program is now open! No matter if you are junior or senior faculty, if you work on math/physics/computer science/ML applied to life sciences, you are welcome to submit an application to come and collaborate with the groups at CSBD! Deadline is November 30th.

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.

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!😋

Phase behavior of Cacio e Pepe sauce “Pasta alla Cacio e pepe” is a traditional Italian dish made with pasta, pecorino cheese, and pepper. Despite its simple ingredient list, achieving the perfect

Huge congratulations @gbart.bsky.social, Daniel M. Busiello, Matteo Ciarchi, Alberto Corticelli, Ivan Di Terlizzi, Fabrizio Olmeda, Davide Revignas, @vicioms.bsky.social l from the entire @mpipks.bsky.social community for ensuring that our cacio e pepe sauce will avoid the dreaded mozzarella phase!

Tipsy bats and perfect pasta: Ig Nobels celebrate ‘improbable’ research The annual awards are a celebration of weird but thought-provoking science.

IG Nobel Prize in #Physics 2025 to @mpipks.bsky.social researchers for elucidating the phase behaviour of cacio e pepe sauce. The work highlights how physics can also be applied to solve daily-life problems!

Bacteria are surrounded by water! New work @natphys.nature.com by @ricardalert.bsky.social @mpipks.bsky.social & collaborators @ Princeton University shows that water capillary forces organise bacterial colonies into gas, nematic streams, and droplet states.

Another look at the drosophila wing! Frank Julicher @mpipks.bsky.social looks at how the wing forms within the pupal phase of morphogenesis. He discussed the physics underlying a hexatic crystalline order found in the wing epithelium that is controlled by cell size heterogeneity. #MBIMPG2025

Paper alert!🧪
We derive a theory that underpins interface resistance with a physical foundation and look at how it changes droplet growth and recovery kinetics! Awesome collab with @bosste.bsky.social Tyler Harmon @hymanlab.bsky.social @m-pol.bsky.social and Frank Jülicher @mpipks.bsky.social 1/4
