I don’t know who needs to hear this, but if I’m booking it down the road on my bike and glance at my wrist, I’m probably not looking for a “keep it up” (that can only be dismissed by swiping WITH MY OTHER HAND). I probably want to see what time it is. Thanks for coming to my TED talk.

Please repost! This comes from the good people at ChimeraX, who produce powerful up-to-date software to study protein (etc) structures, which are FREE to the community. 🙏 To stay viable and serve us, they need an experienced structural biologist to assume the leadership role on a funded project.

ROCKET 🚀 inference-time optimization of AlphaFold to fit structural data is published! rdcu.be/fa9YH Since our preprint, we’ve pushed it to regimes where other methods break: low resolution, weak signal, real experimental edge cases. Here’s what we learned: 1/15

The juvenile sea squirt swims the ocean currents, actively searching for the perfect place to live. Once it finds a nice, solid rock, it sticks itself down and gets to work reabsorbing bits it no longer needs - including its own brain. This post is about human civilisation.

This is amazing work lead by Tom (@tlitfin.bsky.social) in my team. Always trying to get more for less and making computing efficient. So satisfying making science resources go further. Boltz2 is great for protein structure prediction and hopefully LMI4Boltz extends its use. Code on GitHub… 🧶🧬

Had a very long social media break after the last #SynchrotronMugMadness and the bird site's decent into horror. So hello bluesky, I'm a staff structural biologist helping @imperiallifesci.bsky.social solve protein structures with #crystallography and #CryoEM. Please enjoy these protein crystals 💎

Interviewer: Can you explain this gap on your CV? Evolutionary biology: Well, yeah… but then I’ll have two *new* gaps you’ll want me to explain.

🎄 xmas preprint 🎄 we are excited to share our cryo-EM structure of UBR4 in complex with KCMF1 and CALM1. the PQC ligase forms a massive ubiquitination arena, primed to amplify ubiquitin chains (E4 activity) and boost degradation of defective proteins. www.biorxiv.org/content/10.1...
Architecture of the 1.3 MDa complex of human UBR4 (2 x UBR4/KCMF1/CALM1). Picture shows top and side views of the cryo-EM density map and the modeled structure, colored by protein components and domains.

You know what they say about never releasing on a Friday… what does it say about me that I’m releasing on the last Friday before Christmas? 😬 Anyway, ISOLDE builds for ChimeraX 1.9 are now up. Enjoy!

An interesting finding that some types of HPV infection might be preventing cancer (as opposed to the ones that can cause it). Also features G.K. Chesterton and a brief cameo by RFK Jr.

Man… the fact that there’s a *second* ring galaxy visible in the gap? The sci-fi story (where these are the still-growing explosions from the past firing of some unimaginably powerful galaxy-killing beam weapon) practically writes itself.

Quote from Terry Pratchett’s “Soul Music”:
Rats had featured largely in the history of Ankh-Morpork. Shortly before the Patrician came to power there was a terrible plague of rats. The city council countered it by offering twenty pence for every rat tail. This did, for a week or two, reduce the number of rats—and then people were suddenly queing up with tails, the city treasury was being drained, and no one seemed to be doing much work. And there still seemed to be a lot of rats around. Lord Vetinari had listened carefully while the problem was explained, and had solved the thing with one memorable phrase which said a lot about him, about the folly of bounty offers, and about the natural instinct of Ankh-Morporkians in any situation involving money: “Tax the rat farms.”

Discussing Bluesky migration in terms of liberal flight misses the simple fact that most people use social media for fun not influence and this platform, unlike X and cruddified Facebook, doesn’t feel like you’re wading through shit to reach your friends. It’s not that deep.

For ISOLDE users who like to live on the edge: I uploaded dev builds for ChimeraX 1.8.dev… yesterday. While most things seem fine, if you want to use the “isolde add aa” command then *don’t* use this version. Something badly broken, killing the ChimeraX session.

Bugfix released! Unrelated, but I’d strongly recommend updating to ChimeraX 1.7.1 (particularly for Mac users - the 1.7 release inadvertently left out the Metal2 OpenMM implementation; 1.7.1 should get you back up to full speed).

Ahh, the pitfalls of software design… turns out ISOLDE breaks when you try to load an MTZ file containing only map coefficients (because I basically never use it that way myself, so didn’t notice when I broke it). Will try to push a fixed version out tomorrow.
