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.

Postdoc in Theoretical Biophysics Two postdoc positions (each for two years, funded by Amidex Foundation) are available in theoretical biophysics within the theory group at DyNaMo (Aix-Marseille University).

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

congrats Jonna amazing!! 🤩 👏👏👏

🤔 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!

Hi! I’m a theoretical physicist at the University of Sheffield: sheffield.ac.uk/mps/people/a...

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

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

congrats David this is very cool!!! 😍👏👏👏🥳🥳🥳

The actin cortex acts as a mechanical memory of morphology in confined migrating cells - Nature Physics Cells often navigate through confined spaces. Now it is shown that cells retain a mechanical memory of previous confinement events, which makes them more efficient at migrating through narrow microenv...

🤔 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!

🚨 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!

i’ll start modelling “phonotaxis” asap 😅

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?

weather forecast for Sheffield

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):

Why an overreliance on AI-driven modelling is bad for science Nature - Without clear protocols to catch errors, artificial intelligence’s growing role in science could do more harm than good.

🥳 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)

‘Climate of fear’: Montreal doctor says NYU cancelled her presentation A Montreal doctor says her presentation at NYU was abruptly cancelled and believes the university did so out of fear of being pressured by the Donald Trump administration.

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

ahahah oh no only my mom was supposed to see this footage 🙈 now I officially have to redefine my research 😅

ahahah I figured my time has finally come after >10 years of not stepping near anything more sophisticated than a vacuum..

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?

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.

Turkey Arrests Istanbul Mayor, Key Rival to President Erdogan Ekrem Imamoglu was detained at his home, according to prosecutors, who said the charges against him were related to corruption and terrorism.

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...
