This story is now published in @natplants.nature.com ! 🎉🎩 Check out the final article here: nature.com/articles/s41477-026-02361-1 Very similar to the original bioRxiv preprint, with the addition of some cool polysome analysis (in the supplementals)! Thanks and congrats to everyone involved! 🙏

Chloroplast-encoded small subunit extensions reshape the Chlamydomonas chlororibosome - Nature PlantsUsing in situ cryo-electron tomography, researchers found a unique ‘arm’ domain on the small subunit of Chlamydomonas chlororibosomes. This discovery suggests that chlororibosome structure is more evo...www.nature.comFlorent Waltz

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! 1/n 🧵

Big boyyyyyy

Excited to share my paper! 🥳 Today in #Nature we reveal an 8 MDa Hdr electron bifurcating super-assembly in class I methanogens that couples the first and last steps of hydrogenotrophic methanogenesis. A lineage-specific adaptation to anaerobic niches. www.nature.com/articles/s41...

Oh man ... how are we going to deposit that (230+ chains). And there's a another with more 🥲... #DepositionNightmare #CryoEM #CryoET

If you like cilia, go work with my friend Caitie! 👸🏼🥳🔬 Also, guaranteed unlimited lab snacks 🍬🍫🥨🥯

Caitie McCafferty

Happy to finally share that I will be starting my independent group at the @fmiscience.bsky.social in Feb 2027 in a vibrant new environment. We will use integrative in situ structural cell biology methods to investigate ciliary structure and dynamics in several model (and non-model 👀) systems!!

Congratulations to Mariia for her presentation prize! 🥳🥳 Proud! 🥹

Mariia Melnik

The 14th International Conference for Plant Mitochondrial Biology😍🍜🍀 My first trip to Japan and my first presentation award! Many thanks to the organizers, my supervisor, @florentwaltz.bsky.social, and our wonderful collaborators! I was happy to present my work in beautiful Kagoshima🌋

Oh no it's that time again .... Rererererereprocess! Can't wait to try it !

We're super excited to share MissAlignment: a new ML-based approach to reference-free tilt series alignment, spearheaded by @martenchaillet.bsky.social. We think it's going to make your cryo-ET life a lot better. Preprint: www.biorxiv.org/content/10.6... Code: github.com/warpem/miss-... 🧶 Thread:

Coming back from the "traditional" yearly trip to Paris 🥖 Great scientific interactions at IBPC @bpm7099.bsky.social and SOLEIL synchrotron, plus the warm and sunny ☀️ weather, perfect combo! Our little sample Dewar even got it's own baby seat 💺 See you next time!

Check out this cool integrative structural biology story from my colleague @computingcaitie.bsky.social on mammalian cilia 🍟 Beautiful tomos of the ciliary base !

Caitie McCafferty

I am excited to share our most recent work collaborating with @centriolelab.bsky.social and @stearnslab.bsky.social to look at the ciliary base of mammalian multiciliated cells w/ cryo-ET, XL/MS, and U-ExM www.biorxiv.org/content/10.6...

Spent too much time in situ and forgot the level of detail you get with SPA 🍩 #cryoEM

You want to work on carbon concentration mechanisms in algae 🫑? Go work with my (soon-to-be-former) colleague @manondemulder.bsky.social in Vienna @gmivienna.bsky.social ! Cryo-ET 🔬 and funky bugs 🦠 #CryoET #CryoEM

Manon Demulder

Excited to announce I’m starting a new lab at @gmivienna.bsky.social (Vienna BioCentre) in Sept 2026 We study how carbon fixation is inherited and maintained in algae using cryo-ET, imaging, environmental sampling&more Looking for people who want to build the lab together, get in touch! #teamtomo

Had a great time in Zurich for the annual LS² meeting. Nice gathering of the swiss scientific community, always cool to see what the neighbors are doing 😜

Life Sciences Switzerland (LS2)

It’s the final day of the LS² Annual Meeting 2026! Highlights include the Jennifer Lippincott-Schwartz keynote, multiple parallel symposia, and the Friedrich Miescher Award Lecture. Huge thanks to all sponsors for making this fantastic meeting possible! #LS2AM2026 @scnat.ch

Check this new study on carbon concentration mechanisms! See how the pyrenoid changes by modifying Rubisco linkers in our favorite alga, Chlamy 💚! My desk mate @phaips.vd.st spent a lot of time collecting & carefully analyzing these beautiful tomograms 🔬. Congrats to all the authors!

How does molecular valency shape condensate assembly and function? We used the CO2-fixing organelle in algae—the pyrenoid—to find out… 🧵 Preprint here!: www.biorxiv.org/content/10.6... @cellarchlab.com @phaips.vd.st @biologyatyork.bsky.social #Rubisco #PhaseSeparation #Condensates #Pyrenoid
