As a farewell present, the biology department at Leiden University commissioned @lizahaart.bsky.social - thank you for this wonderful portrait!

🦠 Mycobacteria aren't just tough, they're interior designers! 🦠 Check out our latest #preprint 🚨, led by our PhD student @camimille.bsky.social , where we show that #Mycobacterium tuberculosis builds secret cytoplasmic membranes to adapt its metabolism and sneak past immunity 🤫 Thread coming soon!

Can’t wait to join this event!

Registration is open! Come join us at the sensory transduction in microorganisms GRC! Spread the word! www.grc.org/sensory-tran...

Congratulations to the one and only Lucy Shapiro on winning the Lasker! So deserved- Lucy is a true role model! 🎉

So grateful to work with this wonderful team of scientists!

Another week, another episode of #MattersMicrobial! Dr. Dennis Claessen of Leiden University joins the #QualityQuorum to chat about cell wall deficient bacteria, antibiotic resistance, and perhaps insights into how life evolved. Please spread the #GoodMicrobialWord? youtu.be/NIrmcitpBp8?...

New preprint! We examined the morphological plasticity of Chitinophaga pinensis and how its small spherical cells differ from spores - revealing potential ecological roles in passive dispersal via hitchhiking. www.biorxiv.org/content/10.1...

BPS is in San Francisco next year! www.biophysics.org/2026meeting

It was so much fun to give out our stickers promoting our symbiosis model system at the 3dem grc (designed by our very own @verawilliams.bsky.social in our unit @institutpasteur.bsky.social). Where did your stickers end up- post pictures! Most creative picture wins more stickers!

An amazing CryoEM GRC comes to an end! Thank you Julia Mahamid for a stellar meeting! See you all next year in Barcelona!

I have a question for all CryoEM folks here- has anyone done bsl2 pathogen survival tests after a cryocycle? Please let me know if anyone has any insights on this 🙏🙏🙏

🎉 Congratulations to Wolfgang Baumeister @maxplanck.de, awarded the 2025 #ShawPrize in Life Science & Medicine for pioneering work in cryo-ET! Learn more 👉 europa.eu/!JBXDBG #FrontierResearch #ERCSyG #CryoET #StructuralBiology #shawprize2025

Looking for a microbial enthusiast to share their #MicrobialCentrism on my #MattersMicrobial podcast (www.microbe.tv/mm) on June 26th between 7AM - noon. I have been writing to people but not a lot of traction yet. Please spread the word? @asm.org #TheMicrobesYoullKnow

And from the other direction (not mirrored I hope 🤚✋). Thanks so much for hosting us. So, Basel last week and Paris this week…. where’s dinner next week? (For those with keen eyes: there’s another member of #TeamTomo in this photo. But who?🔎)

Great dinner with our cryoET friends from Basel! @sofie-dot-rec.bsky.social @computingcaitie.bsky.social @cellarchlab.com @jacky and Mohamad Harastani

Interested in the microbiome? Don’t miss this meeting at CalTech in September!

You want to start tomography? Solve structures inside cells? Reach Nyquist 😳 ? @phaips.vd.st and I have a website for you! tomoguide.github.io You'll find a tutorial on how to reconstruct tomograms, pick particles and do subtomogram averaging, using different software! Hope it will be useful !

Friends, if anyone is looking for an electron microscopist outside of the US, I'm listening. Open to any country, regardless of weather. Can do cryo, room temp, image anything from tissues to nanoparticles, viruses, catalysts, etc. Thanks for any lead(s).

Thank you @markowenmartin.bsky.social for the amazing gift package! It was an honor and a pleasure joining your podcast and talk about how cryo-electron tomography can help us understand host- microbe interactions using the squid model system! Assembled as instructed 🙂
