What an honor to see @attychang.bsky.social’s work featured in @jcb.org The Year in Cell Biology 2025 collection! Even more special that it coincides with my first #cellbio2025 conference 🙂 s/o to co-authors @baradlab.com @hamid13r.bsky.social @zidlab.bsky.social #teamtomo #cellbio25

@attychang.bsky.social, @nanigrotjahn.bsky.social et al. show that cytoplasmic #ribosomes on #mitochondria alter the local membrane environment for protein import. rupress.org/jcb/article/... 📕 From The Year In Cell Biology: rupress.org/jcb/collecti... #CellBio2025

Prohibitins aren’t hanging out just anywhere in the membrane — they prefer the 💁‍♀️💎✨VIP section💅🪩🥂 Lab all-star @mmedina300kv.bsky.social maps these microdomains using cryo-ET + surface morphometrics. s/o to #teamtomo #cryoET co-authors @hamid13r.bsky.social @attychang.bsky.social @baradlab.com

It’s been a big week for the Grotjahn Lab—our very first graduate student, @mmedina300kv.bsky.social, successfully defended her PhD thesis! 🎉 So proud of everything she’s accomplished and grateful for the light she’s brought to our lab from day one ☀️⚡

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 !

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! tomoguide.github.io Follow the thread 1 /🧵 #CryoET #CryoEM 🔬🧪

So excited for this work to be out!! Thanks to @attychang.bsky.social, @hamid13r.bsky.social, blue sky less Daniel Fuentes, @nanigrotjahn.bsky.social and @tomo.science!!!

🚨New preprint!🚨 #teamtomo We expanded Surface Morphometrics to quantify membrane thickness from cryo-ET—revealing local variation across organelles. Led by the lab’s first grad student, @mmedina300kv.bsky.social (defending Monday! 🍾) w/ @attychang.bsky.social @hamid13r.bsky.social & @tomo.science

We have updated our #MemBrain v2 preprint with a lot more details about the MemBrain-pick and MemBrain-stats modules, as well as some application examples! Stay tuned for the upcoming thread by lead author @lorenzlamm.bsky.social! 🧠🧵 #CryoET #TeamTomo www.biorxiv.org/content/10.1...

Feeling so honored and thrilled to see our work make it to the cover—what a milestone in my career! I can’t wait to receive the poster from JCB🤩

Our April issue is here! rupress.org/jcb/issue/22... The cover shows a segmented model of cytoplasmic #ribosomes associated with mitochondrial membrane in a Saccharomyces cerevisiae cell. From Ya-Ting Chang, @nanigrotjahn.bsky.social and colleagues (doi.org/10.1083/jcb....)

Happy to share the first paper in my PhD is published in JCB! It's my honor to work with amazing teammates! I really enjoy exploring mitochondrial protein import mechanism through cryo-ET!
