It’s been a while since I put together the Structural Virology starter pack, and I’m sure some new folks have joined Bluesky since then. There’s still plenty of space to fill, so if you’d like to be added to the list just let me know.

ProteinCHAOS runs entirely in the browser and lets you choose how to visualize your protein structures.
It supports PDB files from the PDB and AlphaFold servers and offers several visual themes so you can "paint" abstract art with protein traces. I hope it helps you create some interesting images!

10 days and 4 Uni’s later, happy to be back in Oxford with a head full of ideas! Thanks once again @danielhurdiss.bsky.social, Panagiotis Kastritis, @schurlab.bsky.social and Pradyumna Paranjape for hosting me! Enjoyed discussing science with you and your colleagues and lab members!

Spent my childhood in my G’Pa’s chem lab, loved birds then photography and the photography of viruses. Been capturing virus images since 2010 and across 3 continents.

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?

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.
