Thrilled to share that our work with the Ben Black Lab, led by a co-mentored star MD/PhD student Katie Kixmoeller, now is formally published! We used cryo-ET to study kinetochore features in human mitotic chromosomes. 🧬🔬❄️
...and big thanks to @jiwasa.bsky.social for making this amazing video to illustrate the strand-sliding mechanism!
Excited to share our new @science.org paper! Led by postdocs Ruchao Peng and Xin Xu, we used cryo-EM/ET to reveal the influenza ribonucleoprotein complex structure and its strand-sliding mechanism for RNA synthesis, paving the way for new antivirals.

Exciting update on the CryoET Data Portal! A new annotation set from Mart Last & team is now live. They’ve doubled available annotations with >1,800 tomograms of Chlamydomonas reinhardtii which now have almost fully dense labels, and all can be visualized in the browser using Neuroglancer.
