Our research scientist Núria Ros-Rocher won the 1st prize @zeiss-microscopy.bsky.social microscopy contest with this beautiful choano colony www.zeiss.fr/microscopie/... 🥳 C. flexa might not yet be a genetic model, but it is now at least a calendar model, which counts for something. I think.

Why does life explore so few of the forms it could possibly take? Using fractal descriptors, this #scienceadvances paper shows that Earth’s biosphere clusters around simple shapes, reflecting deep evolutionary constraints. @artemyte.bsky.social @manlius.bsky.social www.science.org/doi/pdf/10.1...

I’m pleased to share our latest preprint (my first as 1st-author) from Jérôme Gros’ group (@jeromegros.bsky.social), now on bioRxiv. It reports actin and myosin dynamics during epithelial remodeling in avian gastrulation. (doi: doi.org/10.64898/202...)

To build the body plan of an animal, cells must adhere to one another via cell-cell junctions. We now know these assemble as punctate protein complexes containing thousands of proteins, but how this occurs remains mysterious. 1/n 🧪 www.molbiolcell.org/doi/full/10....

🚨 theory/math devbio preprint alert!!! 🚨 Led by my v. talented PhD student, Daniel Muzatko, we’ve found some rather general and intriguing constraints on reaction-diffusion systems that allow them to self-organize developmental patterns: www.biorxiv.org/content/10.1...

🔈 We’re excited to welcome Jérôme Gros @jeromegros.bsky.social as an invited speaker at #ICDB2025! Jérôme's stunning in vivo imaging reveals the cellular mechanics driving vertebrate morphogenesis. 🎥🐣🧪

🚨New preprint Glad to share my postdoc work on the role of the hypoblast in primitive streak induction! Discover how live imaging observations led us to revisit the molecular mechanisms governing embryonic axis induction Thanks to @jeromegros.bsky.social and all co-authors! doi.org/10.1101/2025...

📢 Fresh off the press and featuring new exciting experiments! 🧪 We show how glycolytic activity instructs germ layer proportions through regulation of Nodal and Wnt signaling - happy to finally share this 😊 doi.org/10.1016/j.st... B2B with @jesseveenvliet.bsky.social lab: doi.org/10.1016/j.st... 🤩

Pu Zhang @puzhang.bsky.social, Taylor Medwig-Kinney @tmedwigkinney.bsky.social, & colleagues from the Goldstein lab found that a population of Arp2/3 recruited to where cells touch each other makes an unexpected contribution to apical constriction rupress.org/jcb/article/...

Out now @naturecomms.bsky.social with extra analyses & data: how distinct gene regulatory dynamics specify vertebrate skeletal cells from three embryonic lineages, how this makes them 'distinct cell types' and what it implies for their evolutionary trajectories > rdcu.be/ecbM2 👏👏 to all co-authors!
