2 weeks to go until the registration/abstract submission deadline for our @cclguk.bsky.social @dmmjournal.bsky.social symposium on the developmental origins of paediatric cancers at the @crick.ac.uk this June. Great speaker line up and slots for short talks: www.cclg.org.uk/information-...

New preprint! We show how mesoscopic nonequilibrium fluctuations in active gels emerge from the breaking of detailed balance at the molecular scale. Warning: Long technical paper ahead! Enjoy! @mpipks.bsky.social @ub.edu @ubics.bsky.social @icreacommunity.bsky.social arxiv.org/abs/2601.20483

Our new paper (with @biotay.bsky.social) is out and on the cover story of @currentbiology.bsky.social !!!! Veronika, a Carinthian mountain cow flexibly uses a “multi-purpose tool” to scratch herself. A video and more information will follow in the comments. www.cell.com/current-biol...

Self-organized or instructed? My @natrevgenet.nature.com Journal Club traces how classic papers revealed two modes of developmental patterning & why the debate between Turing and Wolpert is as timely as ever for organoid engineering today www.nature.com/articles/s41...

I just published: ERC-Plus: jackpot science or missed chance to fix academia? My reflections on ERC-Plus, Europe’s newest ultra-competitive research grant and what it tells us about the academic culture we’re building. medium.com/p/erc-plus-j...

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 www.biorxiv.org/content/10.1...

In May 2024 we had a great workshop on chemotaxis in the MPI PKS in Dresden! The social impressions are in the picture below, and the scientific discussions are summarised in Angewandte Chemie lnkd.in/d6ymRhGK What a nice way to remember!

🚨 Postdoc opportunities in Finland! Are you fascinated by leukocyte navigation and chemotaxis in different disease and tissue contexts? Apply for a 3-year postdoc fellowship with us! More info below 👇 or DM me.

Two 2-year postdoc positions in my theory group — for studying the interplay between metabolism and morphogenesis at the edge of the Calanques and the Mediterranean. More information can be found on: euraxess.ec.europa.eu/jobs/381176 #biophysics

🤔 Can tissue patterning & tumor heterogeneity emerge in a self-organized way? We show that self-organized mechanical stress & density gradients pattern tumors in vitro & in vivo, and this behavior is quantitatively predicted by a mechano-chemical active fluid model! Check out Carlos' thread ⬇️

Thought it would be fitting for my first post to be this little fly illustration I made. Because once a Drosophilist, always a Drosophilist 🪰

How do cells navigate up gradients of adhesive proteins? 🤔 Termed "Haptotaxis", this effect is ubiquitous in cell migration, but it's mechanism was poorly understood We show that passive friction directs cells & explains complex trajectories on gradients 👉 www.nature.com/articles/s41...

I'm a bit late to the party over here. I'll be advertising a BBSRC-funded postdoc position soon. So if anyone wants to solve some outstanding questions in limb development - please get in touch. We have a variety of models and approaches (everything from stem cells to sharks). towerslab.weebly.com

🤔 Can migrating cells 'remember' their past trajectories? In collab w/ @sgabriele.bsky.social & @kyohalie.bsky.social, we address this question: Confined cells undergo geometry-sensitive morphology switches, and these switches depend on the past migration history! www.nature.com/articles/s41...

🚨 New paper out in @pnas.org! 🚨 We show that self-generated gradients allow heterogeneous cell mixtures to co-migrate efficiently over long distances —while optimizing their physical interactions! (See below for 🧵) www.pnas.org/doi/10.1073/... 🧪

This is insane. Labour is making the very same mistake the Tories made but in a more catastrophic way. A left-leaning party adopting an ultra-right fascist agenda: what could go wrong?

Sheffield continues to surprise -I was expecting rain and steel 🥲

..and the same day we get a definition of what a *good* theory is by @robinsall.bsky.social back here on the island 😅 @sheffielduni.bsky.social

here's a plot showing the increase in the number of persons disappeared by ICE (data as posted by @msbr89.bsky.social):

Without clear protocols to catch errors, artificial intelligence’s growing role in science could do more harm than good https://go.nature.com/42nGQt6

University of Derby faces mass job cuts as management plans to make half of senior academics redundant. Please spread the word. www.ucu.org.uk/article/1398...

🥳 Thrilled to share our lab's first preprint, led by our talented postdoc Justine Creff! 👩🏻‍🔬 We tackled a fundamental question: how the epithelium withstands mechanical stress at the interface of cells with distinct geometries and mechanics, such as enterocytes (E) and goblet cells (G) (1/9)

The AHA has released a statement condemning "the dismantling of federal departments and agencies through the indiscriminate termination of federal employees and elimination of programs, including historical offices.” 🗃️

NYU canceled a planned speech by the former president of Doctors Without Borders because she planned to discuss the humanitarian crisis in Gaza and cuts to US AID. This is what actual campus censorship looks like.

another student was disappeared at the University of Minnesota

How do I even put "my doctoral students could not achieve their full scientific potential because they had to worry ICE would abduct them off the street while getting to lab" into a tenure impact statement?

We are excited to be launching the next phase of our Fast & Fair peer review initiative: offering high-quality peer review within 7 working days. #fastandfairpeerreview Read the Editorial by EiC Daniel Gorelick @danielgorelick.bsky.social at: bit.ly/4kYD1mL

Very happy to share our new preprint "MODIS: Multi-Omics Data Integration for Small and Unpaired Datasets"! We proposed a new coupled variational auto-encoder architecture to solve the problem of data integration for small and unpaired datasets (diagonal integration) arxiv.org/abs/2503.18856

It is inherently dangerous to democracy for one man to hold as much wealth and power as Elon Musk. It should be a primary goal of democratic states to prevent such concentrations of power, & to ensure that global plutocrats cannot shut off the arteries of democracy. www.politico.eu/article/musk...

This should be the last straw for the Turkish opposition. Unless there are mass protests, which the government is trying to prevent at all costs, Turkey is now very much a closed autocracy. www.nytimes.com/2025/03/19/w...

🚨 Paper Alert 🚨 Absolutely delighted to share our last paper on "spatial mechano-transcriptomics" @naturemethods👇!! www.nature.com/articles/s41...

NEW — OMB temporarily pauses all agency grants and loans programs. Per copy of memo: "The use of Federal resources to advance Marxist equity, transgenderism, and green new deal social engineering policies is a waste of taxpayer dollars that does not improve the day-to-day lives of those we serve."

Self-generated gradients guide collective cell movement -but often different cell types must move together, e.g. in immune response. We develop a theory of self-generated chemotaxis in mixed populations -are there optimal principles for this cooperation?🤔 www.biorxiv.org/content/10.1...

Happy to share the latest work from Preeti Sahu, with Adriana Sanchez-Danes on the biomechanics of cell fate choices during tumor initiation! We implement/test a 3D vertex model with proliferation and fate choices for multilayered tissues! See 🧵 below (1/n) bit.ly/3ZXxJzk
