Delighted that our story on chromatin architecture inside human cells is now published — the last chapter of my PhD. It was a pleasure working with @sergiocruzleon.bsky.social, @johannesbetz.bsky.social, and everyone involved. #teamtomo www.nature.com/articles/s41...

Molecular architecture of heterochromatin at the nuclear periphery of primary human cells - Nature Communications

The 3D organisation of chromatin inside a human cell is still not fully resolved. Here the authors reveal that in situ cryo-ET resolves individual nucleosomes and predicts DNA linkers, thus showing th...

How do 2 meters of DNA fit inside a nucleus you can barely see? 🧬 Our new study mapped individual nucleosomes inside human cells.

We are sharing a tool developed initially for internal use called VOSE (Volume Operations Simplified Edition) today. It is written specifically to work in ChimeraX (version 1.5+), with no additional libraries necessary to be installed. github.com/jparmachelab...

The peer reviewed version is out. Our study suggests this process is not limited to a single dimer architecture: we identified an additional dimeric arrangement, pointing to greater structural diversity in stress-induced ribosome hibernation-like states. doi.org/10.1093/nar/...

Excited to share our new study: rRNA expansion segments are not passive structural elements — they mediate hibernating ribosome interfaces and reshape translation under stress. www.biorxiv.org/content/10.6...

That’s a wrap on our @embo.org #cryoFIB & #cryoET course! It was an incredible week of hands-on learning, collaboration, and shared expertise, made possible by dedicated organizers, incredible trainers, and an engaged group of participants.

An exciting PhD opportunity investigating ribosome hibernation in cancer is available in my lab, in collaboration with Steffen Scholpp and Ke Li! The interdisciplinary project will span cell biology, structural biology, and AI-guided modelling. Please get in touch if you are interested!

We’ve kicked off our @embo.org Practical Course on #cryoFIB & #cryoET! Participants from around the world are joining us this week for hands-on training, from lamella milling to tomogram reconstruction 🔬

napari needs your help! Has napari helped you make cool and groundbreaking discoveries? We'd love to highlight that in our docs. Please tell us about it! You can fill in this survey: napari.typeform.com/to/vTCKeTKv and/or, as ever, drop by our chat room or meetings: napari.org/dev/community/ 🙏

We're excited to announce the beta-release of #RELION-5.1! 🥳 This release has important updates on our #amyloid processing pipeline, as described in this preprint: doi.org/10.64898/202... There are also some tweaks for #teamtomo. #OpenSoftwareAcceleratesScience
