🚨 #postdoc to be hired in the Paluch Lab 🚨

If you know anyone experienced with and, more importantly, excited about nanoscale architecture of #actincortex and super-res & electron #microscopy do encourage them to apply👇

Amazing colleagues, can only recommend 😉

Des bactéries aux arbres, des coraux aux oiseaux, la vie terrestre semble d’une diversité infinie. Pourtant, une nouvelle étude montre que le vivant n’explore qu’une infime fraction des formes théoriquement possibles.

Cell membranes sustain phospholipid imbalance via cholesterol asymmetry This work challenges a major assumption in cell biology by showing that lipid bilayers can have drastically different phospholipid abundances between their two leaflets. This lipid abundance asymmetry...

Can biological tissues "learn"? Our new preprint shows that epithelial tissues exhibit emergent behaviors akin to unsupervised learning. Local tension remodeling allows cell networks to store long-range memory and program global elasticity properties.

Keeping up with the neighbours: local synchronisation of cell fate decisions during development - EMBO Reports Even before the advent of multicellular life, unicellular creatures would communicate with their neighbours to coordinate their behaviours. Multicellular organisms have the particular challenge of orc...

Hello, here is a review I wrote about how cells sometimes try to synchronise with surrounding cells so that they can do a good job of building tissues during development. It is called "Keeping up with the neighbours"
