Our November issue is available at journals.iucr.org/d/issues/202... On the cover: recent studies demonstrate that the range of samples suitable for cryo-EM single-particle analysis is expanding towards increasingly more native samples. Read the review at shorturl.at/mitjg

We are looking for a computational postdoc to work with us on new optimisation algorithms to make #RELION even better. Join our bubbly team at the @mrclmb.bsky.social in Cambridge, UK. 🤗 RTs appreciated. mrc.tal.net/vx/appcentre...

New online: New York City’s structural biology mosaic

OpenFold3-preview (OF3p) is out: a sneak peek of our AF3-based structure prediction model. Our aim for OF3 is full AF3-parity for every modality. We now believe we have a clear path towards this goal and are releasing OF3p to enable building in the OF3 ecosystem. More👇

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️ Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

October release of DAQ Score DB of cryo-EM str validation! Now includes 255,199 protein chains from 17,283 EMDB maps. Fig is an example with an entire helix having a residue shift. daqdb.kiharalab.org Easy to use DAQ for structure validation in your paper: em.kiharalab.org

Excited to release BoltzGen which brings SOTA folding performance to binder design! The best part of this project is collaborating with a broad network of leading wetlabs that test BoltzGen at an unprecedented scale, showing success on many novel targets and pushing the model to its limits!

I love AlphaFold—but please include PAE (Predicted Aligned Error) plots for every “interaction.” Pretty PDBs ≠ proof. If the PAE doesn’t show an interface, it ain’t one. Show the plots. Structural biology's reputation is on the line.

We are excited to share our latest work on GLIC published in @pnas.org, where we developed a #cryoEM data processing strategy that allowed us to isolate and reconstruct multiple asymmetric states, revealing detailed insights into the channel’s activation mechanism. tinyurl.com/mwtb4rpj

Finally out in print! Long time project with @olexandr.bsky.social and the PHENIX group. Refinement of X-ray and CryoEM structures, using Machine Learned Potentials as the back end to help fitting. This fulfills the old dream of doing QM refinement, but very very cheap www.nature.com/articles/s41...

Is anyone else having problems with NCBI tools? I'm trying to use the CDD database, and it seems completely broken for requests that worked fine before - not sure if shutdown related?

This looks pretty cool and unexpected.... www.biorxiv.org/content/10.1...

So excited to see this project finally come together after 2+ years of development! I’m proud of my contributions, but this success belongs to the entire Structura team — such a great example of what collaboration and creativity can achieve.

I’m proud to live in the state with what looks like the highest density of No Kings protests in the country!

Excellent recommendation, thanks @alisterburt.bsky.social! 🙏 🤓

A university that signs the “compact” is one that acknowledges its own inability to compete and succeed based talent and merit. It would signal insecurity and mediocrity to current and future students and faculty. Say no. Recruit the best people, protect their freedom and support their hard work.

Find a No Kings protest Saturday and go! Don't worry that you've never been to a protest before. Don't worry about being dressed wrong or looking out of place. Don't worry that you don't agree about everything -- or even about much -- with lots of people at the protest. /1

Nominations for the June Almeida award for Mid/Senior-Career Women in Cryo-EM are now open! Submit your nomination via this link www.biophysics.org/awards-fundi... by November 14th to recognize an exceptional woman in our community.

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control. www.science.org/doi/10.1126/...

You may have noticed that AlphaFold3 does not allow covalent bonds between/within polymer chains (protein, DNA, RNA) but allows it for ligands. We tried to go around this limitation by simply treating one of residues/nucleic acids as a ligand.

Oh no! The volume eraser is back! 😳

Super excited about first Shendure/Baker Lab collaboration & preprint on a multiplex sequencing-based strategy for screening de novo proteome editors in mammalian cells. Kudos to the brilliant Chase Suiter (not here) & @greenahn.bsky.social on the work! Preprint here: www.biorxiv.org/content/10.1...

Missed this at the time, super cool. Domes & capsules everywhere it seems..

Check out our preprint! With new molecular mechanisms, 140 subtomogram averages, and ~600 annotated cells under different conditions, we @embl.org were able to describe bacterial populations with in-cell #cryoET. And there’s a surprise at the end 🕵️ www.biorxiv.org/content/10.1... #teamtomo

Looks interesting - currently monomer only, but perhaps one could test on complexes/oligomers using the old GS linker trick? Code available on Github.

Any structural biologists who want some fun? Try building mirror folds. When you’re building them you seriously innately feel like this is “off” but they do exist! When I looked at some of these datasets and deciding which way to turn in Coot it was so offsetting www.biorxiv.org/content/10.1...
