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!

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

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!

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!
