Cryo-ET is often framed as a tool for in situ protein structure. But what if the real revolution is contextualization? I explore how #teamtomo is redefining what "local" means in organelle biology, revealing membrane states rather than just protein structures. tinyurl.com/localmembrane

Think globally, act locally: Redefining organellar membrane environments through cryo-electron tomography
Early enthusiasm for the “cellular revolution” in cryo-electron tomography (cryo-ET) was largely driven by the promise of resolving protein structures…

It’s been fun to put together and write up cryoJAX. Hooray for open-source cryo-EM software! Now it’s time to use it…

Happy to share our cryoEM Ensemble Optimization method! 🎉It infers optimal structures and their weights directly from individual cryoEM images - no maps just physics! with David Sliva-Sánchez, @erikhthiede.bsky.social & Roy Lederman www.biorxiv.org/content/10.6...

Cryo-electron microscopy ensemble optimization using individual particles and physical constraints
Biomolecules are inherently dynamic, and understanding their conformational ensemble distributions is essential for understanding their dynamics and biological roles. Cryo-electron microscopy (cryo-EM...

hey bsky! excited to share what i've been working on for a few years now. cryoJAX: A Cryo-EM Image Simulation Library In JAX www.biorxiv.org/content/10.1... cryoJAX is a modular framework for implementing forward models of cryo-EM image formation. these can be used to build powerful data analyses!
