What makes leaves flat? Beautiful work with spatial and temporal quantification of growing leaves

Our article “Time-dependent bistability leads to critical slowing down during floral transition in Arabidopsis” is now published in @natcomms.nature.com. Link: rdcu.be/fBZ3S. What an exciting collaboration with the Coupland lab! @mpipz.bsky.social @ceplas.bsky.social #PlantDevelopment #criticality

If life builds order from heterogeneity while never completely eliminating it, is heterogeneity merely a byproduct or could it be part of the means by which biological order is generated? Check out Lanxi Hu's review www.sciencedirect.com/science/arti...

Thanks for highlighting our work, and for such a thoughtful interpretation of it!

Our recent paper is explained here in a more accessible way! "We often think of the emergence of order as arising from self-organization or cell–cell interactions, but here, order emerges from random cell fate decisions amplified by the geometry of tissue growth." www.mpipz.mpg.de/pr-formosa-2...

Interested in fossils, evo-devo, and how mathematical modeling can help us understand the evolution of developmental processes? In our latest preprint, we uncover an ancestral lateral inhibition mechanism underlying epidermal patterning in liverworts.

I spent days staring at cells… Their patterns, somewhere between order and disorder, were too beautiful not to create visual pieces from. Whether it was to escape or to see them through another lens. We need more #sciart! Exposed at @figure1a.bsky.social Our scientific story: doi.org/10.1371/jour...

Why are leaf cells of so many different sizes? Our paper explores how giant cells form! We also provide automatic cell-type classification and perform statistical quantification of cell spatial organization. If interested, check it out in @plosbiology.org. Thanks Pau and @roederlab.bsky.social

Check out this highlight of our story on how cells control their size and form nonrandom patterns in leaves (and sepals)! 🍃

Excited to announce our paper is out! Congrats to @pauformosa.bsky.social, @gweissbart.bsky.social, Frances Clark, and Xihang Wang on this fun and beautiful story. We answered a question about the randomness of giant cell spacing that I have had for at least 15 years.

During my PhD, I realized the hardest moments weren’t the work itself, but the psychological challenges. We see lots of productivity tips, but PhD students aren’t machines - they're complex human beings. 🫂 Glad to see well-being in @nature.com 'career column 🍀 www.nature.com/articles/d41...

You’re only human: a six-step strategy to surviving your PhD

Graduate students are not machines. Behaving like one during your programme will leave you frustrated and unfulfilled, says Gauthier Weissbart.

Is giant cell patterning random in sepals and leaves? Check out our new work combining quantitative microscopy, computational methods and modeling, a great collaboration with the Roeder Lab, with F.Clark, G.Weissbart, X.Wang, A.Roeder and co-authors! @ceplas.bsky.social biorxiv.org/content/10.1...
