🚨 Preprint alert! We solved the structure of human NSUN2 bound to Asp tRNA, revealing how it installs m⁵C and recognizes RNAs #CryoEM #RNABiology A collab between Casañal & Gullerova labs, with @miclass.bsky.social and me working side by side as co-first authors 🔗 doi.org/10.64898/202... (0/7🧵)

Stoic 🦾 from our shared student @daniil-litvinov.bsky.social predicts protein complex stoichiometry. A fun collab with @ninjani.bsky.social @torstenschwede.bsky.social - this #AI adventure beyond our core #CryoET methods was made possible by the @biozentrum.unibas.ch PhD Fellowship Program! 🧪 🧶🧬

Did you see this post think “Oh damn! I have this really cool story but not enough time to submit!”. Well we heard you! And extended the deadline to 30.03.2026! Send your abstracts in for a chance to present in Autumn!

If you have computational and physics chops go work with @bforsb.bsky.social . You will mot be disappointed!

I've written a review on what I think is an extremely exciting direction in cryo-EM: Cryo-EM of endogenous membrane proteins in their native lipid bilayer Open access in Quarterly Reviews of Biophysics: doi.org/10.1017/S003...

Remember that everyone you meet is fighting their own battle, sometimes with amino acids

Abstract submission closes this Friday. If you have a story to tell and have just seen this do apply! @dbhella.bsky.social and myself look forward to your abstracts!

The deadline for applying to the open postdoc position in our lab is coming up! Reach out if you have questions about the project, our lab and ISTA!

2/5 When you have ALS, you experiment. Supplements, drugs, hope. See alsuntangled.com for why that's so common. So I built ALSTracker. It won't give you certainty. But it replaces gut feeling with something more solid: Bayesian statistics. alstracker.mpi-dortmund.mpg.dee

Tired of drawing cilia or centrioles for slides and papers? I feel you. Check out CiliaBuilder for ChimeraX → cxtoolshed.rbvi.ucsf.edu/apps/chimera... Build custom 3D cilia & centriole models (tips + primary cilia included).

New preprint by @alok-bharadwaj.bsky.social explaining the workings of SURFER, a simple tool to segment membrane, micelle or nanodisc densities in cryoEM maps. Try it via the @chimerax.ucsf.edu ToolShed: cxtoolshed.rbvi.ucsf.edu/apps/chimera... Despite LocScale in the name, it works on any map.

I cannot see how @microsoft.com can classify its tools as productivity tools. Teams is by far the worst thing on the planet and I DO NOT underestand how organisations including Universities and Governments have bought into this system whole-heartedly!

Just installed and twiddled a few knobs, but I am already impressed with `himena relion`. Amazing job @liu-hanjin.bsky.social! Would be great if this could be made into a default interface for relion.

Funded PhD studentship (UK students only) available on clinical proteomics, application deadline 22nd March for Oct 2026 start! This project seeks to understand treatment responses to exacerbations experienced by people with CF using proteomics. www.findaphd.com/phds/project...

Since last year, I've been making a RELION GUI that supports viewing, navigating and running jobs in a way completely compatible with the original RELION pipeline. Now it's working nicely for both SPA and tomography! Please try it out - github.com/hanjinliu/hi...

Fantastic effort!

Integrase anchors viral RNA to the HIV-1 capsid interior pubmed.ncbi.nlm.nih.gov/41708858/ #cryoem

Researchers have uncovered an unexpected second function of one of HIV’s key proteins. This discovery could pave the way for new types of treatments. www.crick.ac.uk/news/2026-02...

priviliged to be witnessing these amazing cellular vistas! makes you wonder about all the unknownwhat biology is being captured here!

Do you find yourself looking at 100s of tomograms and keeping an excel sheet description of what is in them? I certainly do! So, I asked Claude to put together this (buggy) little webapp called TomCat, which you can freely download from here (github.com/shahpnmlab/t...)

I had Claude make this as a mini-game for Relay's disconnect screen (like Chrome's dinosaur), but then pivoted to stand-alone. In this game, you have to find Euler angles matching the target projection, i.e. cosplay RELION. It can be pretty hard. Works on mobile too! warpem.github.io/euler-hunt/

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller? Excited to share our latest work in @science.org on a new small polymerase. 1/n

I am excited to share our latest preprint - An evolutionarily divergent herpesvirus with a giant tail. Featuring symmetry breaking and genome annotation from structure using ModelAngelo. doi.org/10.64898/202...

Open Postdoc position in our lab! #actin #Huntingtin #cryoET #cellbio If you enjoy working at the interface of cell biology, structural biology, and quantitative imaging, this could be an excellent fit. ista.ac.at/en/job/postd... Please share and feel free to reach out if there are questions!

Mosquitoes like Aedes aegypti spread viruses that cause major global diseases. We decided to have a closer look at a family of mosquito carbohydrate-binding proteins involved in infecting these vector species. We found some unexpected things 😁 Preprint out now 🦟🦟🦟 www.biorxiv.org/content/10.6...

Caveolins are conserved (metazoan) proteins essential for forming membrane-derived vesicles called caveolae. While evolutionarily distant caveolins have similar structures, we found they do not maintain caveolae-generating capabilities (movie). What determines this? Check out our new preprint!

Check out this cool thread on the latest preprint by Gaurav Kumar, @james-r-barrett.bsky.social, @phaips.vd.st from our lab and colleagues, dissecting the physics of Rubisco condensates! You're in for some stunning #cryoET of the pyrenoid - in Chlamy, of course 😉 Congrats to all involved!

Cryo-EM structure reveals how influenza A virus NEP binds the viral polymerase at a regulatory hotspot, coordinating RNA synthesis and nuclear export. Fantastic collaboration with @loiccarrique.bsky.social and Jon Grimes. www.science.org/doi/10.1126/...

We are running the cryo-ET image processing workshop again this year! Come learn everything tomo: STA, segmentation, heterogeneity analysis from @baradlab.com @williamnwan.bsky.social and others! Apply!

Amazing!!

I’m excited to announce that I will be starting my research group on computational enzyme design at the Generative Biology Institute, Oxford, UK (@eitoxford.bsky.social)! PhD applications are open, deadline is Jan 8th (www.chem.ox.ac.uk/genbio-dtp). Email [email protected] with any questions!

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. #virology #cryoEM go.bsky.app/Qxv95BL

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.

Scientific journals: we don’t want you using generative AI because it makes shit up. Same journal: here is an AI summary or evaluation of this paper. This might be more useful than the actual abstract or paper that the authors freaking wrote Same journal: AI cover art which makes no sense? Oooh!

Insightful!

Our lab is seeking a Postdoctoral Fellow. The position is intentionally broad, as we are looking for outstanding researchers from diverse scientific backgrounds to advance our understanding of cilia and ciliopathies: academicpositions.harvard.edu/postings/15526

Thank you for hosting me @danielhurdiss.bsky.social at @utrechtvirology.bsky.social! It was wonderful to visit and spend time with the members of the group. Until next time!

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? 👇

Jeremy is an excellent scientist and leader. Highly recommended!
