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! 🙏🏽

Our new preprint is out 🥳🥳🥳

Henipaviruses, like Nipah and Hendra, package their genomes inside helical shells built by thousands of nucleoproteins. These nucleocapsids are essential to protect the viral RNA, but how do they ever let the polymerase in to read the sequence?

I am advertising for a PhD position in my group. We'll be investigating how pathogenic RNA viruses replicate in the nucleus. The project will teach cryoEM/ET, virus culture, and in vitro assays.

If you're interested reach out and I'd be happy to have a chat.

Really excited to have our work out in the world. CCHFV has a 450kDa L-Protein, about twice the size of L-Proteins from other segmented RNA viruses. We have used cryoEM and functional assays to begin to understand it this massive multifunctional protein works.

End-to-end protein design in the browser through evedesign. Generate and interactively explore designs in 2D/3D and export them as codon-optimized DNA. The underlying open source framework (released soon) is build to easily add new methods, more on that soon.

Neat!
Ever wondered how to position organelles in bacteria? Wonder no more!
Happy to have contributed to this fantastic story from @cellforganized.bsky.social' lab.

The avenues this opens in the synthetic biology space are enormous!

Our aim was to create a kit to produce in-house 1.2 holey carbon cryoEM grids, in three simple steps, at less than half of the prize, and without due times. I think we are there. Academic teams that want to know more, receive training or order a kit, please contact grids@puxano.com.

We finally wrote up the paper for LocScale-2.0.

edu.nl/pvhxv

Please try it out. LocScale is evolving & we are actively building in new features and improvements. Your feedback will help us shape the next steps.

Code: cryotud.github.io/locscale/

Work by @alok-bharadwaj.bsky.social and Reinier.
We are happy to release LocScale2.0: a tool for context-aware, confidence-weighted cryoEM map optimisation.

Taking two half maps as input, LcoScale-2.0 produces feature-enhanced maps along with a robust confidence score that guides objective map interpretation.

This one is a bit of a departure from the usual and definitely a work in progress!

We found that by using ab initio reconstruction at very high res, in very small steps, we could crack some small structures that had eluded us - e.g. 39kDa iPKAc (EMPIAR-10252), below.

Latest preprint from the lab, many years in the making!

By combining #cryoEM with #AlphaFold3 modelling, we propose that norovirus NS3 forms a transmembrane RNA translocase.

This could have big implications for our understanding of viral replication & assembly (🧵)
