Just published! at @narjournal.bsky.social . A new example of how gene order in bacterial genomes impacts cell physiology. Inthis episode we messed up with RNA polymerase genes! academic.oup.com/nar/article/...

Evolutionary constraints on RNA polymerase gene positioning in the genome of fast-growing bacteria
Abstract. How gene order along chromosomes affects cellular homeostasis and genome evolution remains poorly understood. Bacterial chromosomes are organized

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/

Can you find the Euler angles of a cryo-EM projection?

❗New Preprint w/ C Bueno (‪@cabb99.bsky.social‬), IE Sánchez (@nachoquique.bsky.social‬), PG Wolynes & DU Ferreiro (@diegulise.bsky.social‬) We define the Protein Dark Energy and use it to localize and quantify the functional evolutionary constraints on natural proteins arxiv.org/abs/2508.08109

Probing the Dark Energy in the Functional Protein Universe
We show how to localize and quantify the functional evolutionary constraints on natural proteins. The method compares the perturbations caused by local sequence variants to the energetics of the prote...

1/x New story - the structure of the Vault cap, at 2.3Å! Matching a beautiful preprint from @sjorsscheres.bsky.social, we show that the cap of the vault particle has C13 symmetry, in contrast to the 39-fold symmetry of the body. Study lead by talented postdoc @huanli00.bsky.social from my group! ⬇️
At left, a reconstruction of the vault cap with C39 symmetry imposed; at right, the reconstruction after identifying the correct symmetry, with the three non-equivalent protomers highlighted.

I'm super happy that our story is now published! 📖 www.science.org/doi/10.1126/... But what changed compared to the original preprint? Also, I feel i should post Movie 1 🎥, that inspired the cover. Back when I did the original bluesky thread, movies were not available.

Out just now @naturecomms.bsky.social: using cryo-EM and cryo-electron tomography, we provide evidence that structurally heterogeneous ribosomes can cooperate in protein synthesis in bacterial cells: www.nature.com/articles/s41...

Cells can simultaneously produce structurally dissimilar ribosomes, suggesting functional specialization of distinct ribosome populations. Here, the authors show that distinct ribosomes cooperate rath...

Mature #HIV-1 contains >2000 copies of “spacer peptide 2”, but we didn’t know why. We now see that SP2 binds the matrix protein and triggers the change into its mature arrangement. Summary video from @margotriggi.bsky.social
