With deep sadness, we share that Prof. Jochen Guck, Director at the Max Planck Institute for the Science of Light passed away on October 3. His visionary work bridged physics and medicine. We have lost a brilliant scientist and dear friend.

New preprint from the lab! We discovered a transient fluidization in the basal region of human forebrains by tracking microdroplets in cerebral organoids.This “basal fluidization”, absent in gorilla and mouse, may contribute to greater surface expansion in human forebrains

How is developmental speed regulated ? 🪰

Happy to share my PhD story from Schweisguth Lab @devstempasteur.bsky.social. Here we show that cellular NAD+ availability and redox constrain developmental speed in the fly eye.

We only had a very minor contribution to this story with Alexis, but definitly worth a reading for those interested by patterning, precision and refinment. Nice combining of quantitative live imaging, modeling and optogenetics to dissect vein patterning dynamics

A though provocative idea potentially connecting cell metabolic state and sensitivity to mechanical stress (and thus potentially relevant for cell competition)

Epithelial crowding drives membrane depolarisation by ENaC/Na+ entry which triggers rapid volume loss, piezo activation and live cell extrusion. Importantly, low intracellular ATP primes cells for live extrusion by preventing the restoring of mb polarisation.

Crowded epithelial cells with the least energy and membrane potential are selected for extrusion.

Interesting changes for the ERC evaluation, including an extension of the eligibility period for StG and CoG (now up to 10 and 15 years post phd respectively). Worth a reading for those intending to apply in the coming years (and nice to see that the council keeps trying to improve the process)

European Research Council (ERC) @erc.europa.eu · 23d

Based on feedback from applicants, reviewers and broader research community, the ERC Scientific Council decided to make changes in the 2026–27 calls for proposal for research funding.

I may have a biased interpretation here, but I suspect the background of @danielkrueger.bsky.social in fly morphogenesis brought a lot here (congrat for the impressive work !) , a good example of virtuous background mixing and work built on important conceptual/technical premise from model organism

This is very complementary with the recent preprint of @xaviertrepat.bsky.social and Maria Matejcic using 2D organoids and providing 3D mechanical characterisation of the process

Important story dissecting the mechanism of gut cell extrusion using organoids. Local heterogeneity of tension promotes live extrusion and basal relaxation is sufficient to kick the cell out. Nice combination of optogenetics and live imaging to demonstrate this

Beautiful story that combined mechanobiology, evolution, and the power of fly (opto)genetics to make sense of the cephalic furrow. It was a pleasure writing the News & Views. No doubt this is still just the beginning for the field of mechano-evo-devo! Hats off to all involved
