Yeh, Martin @mit.edu et al examine the #Drosophila synaptotagmin-like protein Btsz in early embryo nuclear divisions, identifying a role for regulating pseudo-cleavage furrow stability. They show that Btsz bundles #actin filament networks in vitro. rupress.org/jcb/article/...

Our latest work on shape-programmable tissues is out in @science.org. By positioning topological defects in cellular nematics, we encode frustrated 2D force fields that relax into predictable 3D shapes. Collaboration with Marino Arroyo’s lab, led by @pauguillamat.bsky.social at @ibecbarcelona.eu.

⚡ Our paper is now out in @natphys.nature.com !
This version now includes a detailed molecular characterisation of the optogenetic perturbations, new insights on the relevance of tricellular junctions for tissue morphology, and beautiful light-sheet timelapses. 🔬

For decades, cellular aggregation was considered an evolutionary dead end.
Cells could come together temporarily.
But complex multicellular organisms like animals?
Our study, led by JP Gerdt, with Ruibao & @jennahed.bsky.social suggests it may be time to rethink that🧵 #ProtistsOnSKy
Our work on Trichoplax locomotion and mechanosensing capabilities is out now in @currentbiology.bsky.social.
Congrats Marvin Leria & all co-authors!

Tissue phase transitions are key to morphogenesis. Now adhesion-driven rigidification is identified as key to epithelial organization but only if uncoupled from density-driven jamming.
