Sauf qu'en Bretagne, elle a rendez-vous avec les nuages 😜 On désespère pas que tu viennes nous faire une conférence à l'Institut de Génétique et Développement de Rennes un de ces quatre 😉

🚨 Webinar Alert! - Revolutionizing Structural Biology
On Oct 1 Dr. Nick Ariotti (U. Queensland) will share how his team imaged microtubules in lysate at 7.1 Å with a cryoTEM and NO traditional purification steps.

Happy to share that our paper on Tau- Microtubule interaction is now published in Nature Physics!🥳

We show that Tau isn’t just a microtubule stabiliser - it promotes removal of defects in the microtubule lattice.

Congratulations @subhambiswas.bsky.social!

The LMB recently hosted a symposium to mark 50 years since Richard Henderson and Nigel Unwin published the structure of bacteriorhodopsin, the first 3D structure of a protein determined by #cryoEM.

After 5 amazing years @pilhoferlab.bsky.social I'm starting my lab @embl.org Grenoble this November embl.org/wollweber
We'll image Asgard archaea and many other strange microbes ( #archaeasky, #protistsonsky..) to understand eukaryogenesis

Our paper on Lymphostatin is now out (rdcu.be/etk2v). It shows #cryoEM structures of this huge virulence factor revealing amazing domain reorganisations.
Very enjoyable collaborating with the Stevens Lab in Edinburgh and the Boersch Lab in Jena to see how it gets into cells.

🚨 New preprint!
Using U-ExM + in situ cryo-ET, we show how C2CD3 builds an in-to-out radial architecture connecting the distal centriole lumen to its appendages. Great collab with @cellarchlab.com @chgenoud.bsky.social @stearnslab.bsky.social 🙌. #TeamTomo #UExM

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.

Zoom into a human cell infected by Shigella, the bacteria behind dysentery. Using cryo-EM, @leaswistak.bsky.social and team revealed how it pierces cells with molecular syringes. Stunning science at the nanoscale.

Hey #TeamTomo,
Ever been in need of a tutorial about the fundamentals of cryo-electron tomography? From preprocessing raw frames to high-res subtomogram averaging?
That's why @florentwaltz.bsky.social and I made this website!

It's #MicroscopyMonday, so let's take a peek into the 🔬
This movie was taken by Shinya Inuoe, who built the polarizing microscope that allowed scientists to see mitotic spindle fibers live for the first time.

Dr. Inuoe premiered his research at MBL.
