gapTrick - Structural characterisation of protein-protein interactions using AlphaFold pubmed.ncbi.nlm.nih.gov/40985612/ #cryoEM

hey bluesky 👋 visa hurdles mean I’m looking for opportunities outside the US. I’m a computational biologist (bacterial + phage genomics, postdoc in Koonin’s group @ NIH). I am interested in teaming up on funding apps. reach out if this resonates!

Very impressive results and interesting approach. One can now wonder if the theoretical size limit still holds true. Has anyone tried to look at, e.g. lysozyme in cryoEM?

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.

Determinants of human versus mosquito cell entry by the Chikungunya virus envelope proteins Chikungunya virus (CHIKV) infects both humans and mosquitoes during its transmission cycle. How the virus’s envelope proteins mediate entry in cells from such different species is unclear. MXRA8 is a ...

In new study led by Xiaohui Ju, we define how mutations to Chikungunya virus envelope proteins affect entry in human vs mosquito cells.

Sheds light on functional constraints & enables us to make loss-of-tropism mutants, which could be of use for vaccines.

Congratulations! Such an amazing and user friendly tool.

A realistic phantom dataset for benchmarking cryo-ET data annotation - Nature Methods A standardized, realistic phantom dataset consisting of ground-truth annotations for six diverse molecular species is provided as a community resource for cryo-electron-tomography algorithm benchmarki...

Better ML for cryo-ET starts with better benchmarks.

We built a phantom cryo-ET dataset (~500 tomograms) + hosted a Kaggle challenge.

The result: community models beat expert tools.

Open Call for Expressions of Interest in Max Planck Directorships: Expressions of interest can be submitted until 31 October 2025.

Director at Max Planck - a unique position! The Open Call for Expressions of Interest in Max Planck Directorships is open now and can be submitted by the 31st of October 2025. ➡️ mpg.de/directors - Please share the Open Call among potential candidates.

Scientific bedlam at the world’s weirdest and wildest research conference Woodstock Bio2 + Night Science aimed to encourage collaborations through creativity. The walk-on music for presentations was fun, too.

🥂This was the highlight of my year. The "instigators", led by local master of the ceremony @svobodalab.bsky.social will never forget the privilege of organizing it and i think every participant will treasure the experience forever ❤️ @nature.com @josiegz.bsky.social www.nature.com/articles/d41...

Please RT! Call for Fellows! If you’re a structural biologist and wanting to start your lab by applying for an external Fellowship then we at Imperial may be excited to host you. Synthetic biologists too.. Please submit expression of interest with details below 🙏

Excited to share my final work from the @soreklab.bsky.social!

We mined phage dark matter using structural features shared by anti-defense proteins (viral tools that help phages bypass bacterial immunity) to guide discovery.

Found 3 new families targeting immune signaling!

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.

cryotud.github.io/locscale/

LocScale-2.0 is deliberately designed to optimise contrast for both high-resolution detail & weak contextual densities such as membrane/micelle or flexible/low-occupancy regions

LocScale-SURFER is a ChimeraX plugin aiding w/ visualisation of contextual structure.
