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

🤔 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...

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...

🚨 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!

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?

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.

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.

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...
