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.

The paper is out which means the MD trajectories are finally available! #MolecularNodes #b3d #GeometryNodes

New preprint on 3D heterochromatin architecture in human cells! Great collab with @sergiocruzleon.bsky.social & @johannesbetz.bsky.social from @hummerlab.bsky.social, @marinalusic.bsky.social & the Turoňová lab. Many thanks to my supervisor @becklab.bsky.social. bioRxiv: tinyurl.com/3a74uanv 🧵👇

1/3: We are proud to share that the recent work by postdocs Karen Palacio-Rodriguez and Sergio Cruz-León, from Gerhard Hummer’s department, was selected as one of the Editors’ Highlights in Nature Communications! 🎉 👏 Open-access paper: 👉 www.nature.com/articles/s41...

The scientific part of the event starts with a talk by @sergiocruzleon.bsky.social on bridging in-situ cry-ET and multi scale simulations

We resolved the molecular architecture of a condensate—inside cells. 🤯 By combining in situ cryoET with multiscale simulations, we show how a single point mutation modifies molecular interactions, shifts the condensate’s material properties, and alters its biological function. Preprint 👇

We are excited to share our new preprint which is now available to read on biorXiv: doi.org/10.64898/202... 🎉🎉🎉

It’s out! Using cryo-ET in Dicty cells, we take a fresh in situ look at vaults. Surprisingly, we uncover vaults associated with ER and NE membranes, and find that many vaults enclose ribosomes in defined orientations, opening new avenues to their cellular function! www.biorxiv.org/lookup/conte...

We developed a 'smart STED microscope' to detect rare objects/events in cells, and unraveled the 3D morphology of a nuclear membraneless organelle (paraspeckle). Amazing collaboration with Sjoerd Stallinga, Bernd Rieger (TU Delft) and @mixmue.bsky.social 🙏 (1/3) www.nature.com/articles/s41...

Just published! We share an open-source workflow to measure membrane thickness from tomograms, including a tutorial with 3D visualizations. We analyze thickness variations across organelles and reflect on where to define a membrane boundary. @becklab.bsky.social #teamtomo rupress.org/jcb/article/...
