Hello, old and new friends in Bluesky.
Using cryo-FIB-ET, we revealed a 9Å structure, identifying novel layers and conserved interfaces that may serve as antiviral targets. #Ebola #Virology #StructuralBiology

Hey #TeamTomo 🧪🔬, ICECREAM is getting tastier! Please give it a try on your tomograms and send us feedback so we can get the recipe just right 🍦😋
I'm pleased to announce 🍦 Icecream 🍨 v0.3!
New features include:
* Training on multiple tomograms (same training time, with linear increase in RAM) 🚀
* Logging and plotting of the loss function 📉
* The --scale option is now called --eq-weight for clarity 😉
We'd love to hear your feedback! 🙏🏽

Just published! We share an open-source workflow to measure membrane thickness from tomograms, including a tutorial with 3D visualizations. We analyze thickness variations across organelles and reflect on where to define a membrane boundary. @becklab.bsky.social #teamtomo rupress.org/jcb/article/...

Conserved nucleocytoplasmic density homeostasis drives cellular organization across eukaryotes - Nature Communications
Cells can regulate their mass density. Here, the authors demonstrate how eukaryotes establish and maintain a lower density in the nucleus than in the cytoplasm via pressure balance, and how deviations emerge during pathophysiological states like senescence.

Our second paper explores the mechanism by which fusion-targeting antibodies neutralize the measles virus. It was exciting to integrate structural biology, virology, and biophysics to demonstrate that these F-targeting antibodies can provide complete protection against measles infection.
