I've written a blog post responding to the letter about maths and AI signed by 25 Fields medallists. As with the Leiden Declaration, I didn't sign it, but I agree with much of it and welcome its existence.

Why I didn’t sign the Fields medallists’ letter
When I was around 11 I heard for the first time about Fermat’s Last Theorem. I was immediately captivated by the problem statement, as well as by the accompanying story, and made a fairly ser…

A new wave turbulence regime in active matter has been found using numerical simulations. When in dense suspensions, active phoretic disks with physico-chemical hydrodynamic interactions remain caged and perform local vibrations.

How do epithelial cells make a lumen as they polarize? We have some exciting new answers to this long standing question. Check out our new paper in which we show that lumen initiation is driven by large vacuoles that deliver a pre-assembled apical cortex to the AMIS: www.nature.com/articles/s41...
Bulk delivery of a preassembled apical surface initiates epithelial lumen formation - Nature Communications
Epithelial lumen formation is fundamental to organ development, yet how apical surfaces first emerge remains unclear. Ghosh, Martin, and Chen et al., show that lumen initiation is driven via bulk deli...

My first paper is officially out in @currentbiology.bsky.social ! We found that snake embryos coil due to a mismatch in growth rates between the gut and spine. This tight coil is one of the reasons why snakes are able to get so long. Read the paper here!
