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.

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

AlphaFold as a prior: experimental structure determination conditioned on a pretrained neural network

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.

My 28 y/o coworker hurt his ankle over the weekend playing ball. (eh. shit happens) He goes to the doc to get an x-ray. WHY did he then take what the doc told him happened and put it into Gemini to figure out what to do? We. Are. Cooked.

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… 🧶🧬

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!

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.

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.
