We've just released StressNET: a machine-learning method that infers the mechanical state of tissues! Check it out! (1/8)

🚨 #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 😉 www.cam.ac.uk/jobs/researc...

Happy to share this work from Carlos Camacho de la Maccora that reveals how rates of posterior progenitor addition and anterior vacuolation are balanced across the notochord. With Alberto Ceccarelli and @osvaldo-chara.bsky.social we present a model of long-range communication to provide robustness.

Mechanical forces can affect the way tissue grows. Ideally, we want to characterize them without interfering with the processes we are studying. Is there a way to achieve this? I am @borgesaugust.bsky.social Welcome to my stress inference tutorial! #EpithelialMechanics

Can we use morphology and dynamics to understand the mechanical state of tissues better? Here is a brief thread about our recent mini-review with @osvaldo-chara.bsky.social !
