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 🔬🧪

In a new Science study, cryo–electron tomography captures the in-cell architecture of the mitochondrial respiratory chain, illuminating how the coordinated action of molecular machines drives life’s fundamental energy conversion. Learn more in this week's issue: scim.ag/3FA3Ygq

To all #TeamTomo #CryoET and #Chlamydomonas aficionados: we have updated EMPIAR-11830 with a bug fix concerning some cryo-CARE denoised tomos as well as additional files and metadata! 🎉👩🏽‍💻 www.ebi.ac.uk/empiar/EMPIA... A little thread about what's new... 🧵 1/n

I am happy to be a part of this effort and looking forward to the discoveries this dataset will enable! If you work with this dataset in the future, please add any annotations to the GitHub repository github.com/Chromatin-St... Thanks @paloha.bsky.social for spearheading the efforts with this!

This large dataset is the result of years of collaborative #TeamTomo work between @abhaykot.bsky.social's TFS team, our @biozentrum.bsky.social group, and the @mpibiochem.bsky.social crew led by John and Jürgen. Abhay's team used automated plasma #FIB milling and 42 overnight #cryoET sessions! 🧪🔬💪

Towards community-driven visual proteomics! Excited to finally share this large-scale curated & annotated dataset of 1829 high-quality #cryoET tomograms of the little green alga that just keeps giving— Chlamydomonas! 🧪🧶🧬🌾🌊🌍 Preprint📜: www.biorxiv.org/content/10.1... A short thread🧵👇

More than 1'800 tomograms available for the community. Towards visual proteomics using our favorite organism Chlamy! Check out the preprint: www.biorxiv.org/content/10.1... Find it on EMPIAR (11830) and fully annotated on the CZI data portal: cryoetdataportal.czscience.com #TeamTomo

WOW! "Subtomogram averaging Soluble and membrane-bound complexes ranging in size from >3 MDa to ~200 kDa, including 80S ribosomes, Rubisco, nucleosomes, microtubules, clathrin, photosystem II, and mitochondrial ATP synthase. The majority of these density maps reached sub-nanometer resolution..." 🧪

Our first "lab paper" is out: In collaboration with Sandro Ataide and Yichen Zhong (University of Sydney) and Adrian Koh and @abhaykot.bsky.social (TFS), Junjie Feng in my lab determined the structure of the peptide binding domain of SRP68/72, the largest protein components of the eukaryotic SRP.

A fantastic postdoc opportunity with Jon Grimes at Strubi, University of Oxford, to study the molecular mechanisms of viruses using the latest cryo-ET and cryo-SIM technologies. my.corehr.com/pls/uoxrecru...

This was missed due to major live events happening around the same time, but we have released some of our high-resolution (2 Å) and rapid screening #cryoEM maps & models of the human CAK bound to small molecules. Paper still under review - more to follow. www.ebi.ac.uk/emdb/search/...
