Our work on HIV-1 matrix, led by James Stacey and @dhrebik.bsky.social, is in this week's @nature.com. Extended explanatory video from @margotriggi.bsky.social.

High-resolution in situ structures of hantavirus glycoprotein tetramers pubmed.ncbi.nlm.nih.gov/41763200/ #cryoEM

Our latest preprint is now available doi.org/10.1101/2025...! Led by my postdoc, Luqiang Guo @luqiang.bsky.social, we determined a ~2.4 A resolution structure of the hantavirus glycoprotein tetramer on the surface of VLPs. Also determined structures of dimers of tetramers and Fab-bound tetramers.

Please spread the word: the Structural Studies Division @mrclmb.bsky.social is looking for a new tenure-track, independent group leader with an exciting plan in any area of Structural (Molecular & Cell) biology, in discovery biology and/or methods development. 🥳

Congratulations Kelly! And enjoy the holiday!

Long in the making, but happy to present the Chlamydomonas chlororibosome!
Cryo-ET🔬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins.
bioRxiv 📖: shorturl.at/q44tG
This suggests greater chlororibosome diversity than expected!

Not something you see in textbooks very often: tripolar mitosis.

Very happy to say that our work on how axonemes are generated is now available on bioRxiv: www.biorxiv.org/content/10.6... - if you’ve ever wondered how the incredibly beautiful, complex structures within motile #cilia are constructed then this is for you!

Am I the only one increasingly annoyed by cryo-EM papers not showing *any* experimental density in figures? Sometimes not even in the supplementary material??

@erwright73.bsky.social Welcome the Wright Lab to Bluesky! #Tomo

Great work from the Wright Lab at MCCET, Madison! Congratulations to the team!

Cryo-electron tomography reveals coupled flavivirus replication, budding and maturation - Nature Communications In this study, Dahmane et al use a method called cryo-electron tomography to uncover new details of how tick-borne flaviviruses transform cells into virus factories.

I am super happy to share this paper in its final form. We used FIB milling to "dig in to" cell lines and mouse brains infected with tick-borne flaviviruses, followed by cryo-ET to study the virus replication. It's open access, so have a look!

I've reviewed about 150 CVs in the past few days. A few observations: (1) I am sooo impressed by the talent pool out there; (2) do not try to make your CV fit onto one page if it makes things difficult to read - just go multipage, keeping the key messages upfront;

Happy to finally share the amazing results of our long-term collaboration with Karin Reinisch’s lab on how bridge lipid-transfer proteins (BLTPs) cooperate with partner proteins to orchestrate lipid delivery. A quick thread (1/7)

This figure captures how challenging the #cryoEM analysis was, but it doesn't capture the challenges we had to solve in molecular biology, biochemistry, purification, and functional testing. Every step was hard! So glad to see it available.

The golden age of vaccine development - Works in Progress Magazine The first vaccine was a lucky accident. Now we can design new vaccines in weeks, atom by atom.

NEW article by me!

We can now visualize pathogens down to atoms; design vaccines in weeks; manufacture them in microbial factories; engineer them more precise than ever before.

We're living through a golden age of vaccine development, but only if we continue to invest in them.

Hi Sjors, that sounds great! I would love to test relion-5.1. I will drop you an email and follow up.
