This is huge: “A drug that provides near-perfect protection against H.I.V. with shots just twice a year will be made available at $40 per patient annually in low- and middle-income countries, offering new hope… making lenacapavir a realistic choice in countries with constrained resources.”

Jon Chen @jonchenjk.bsky.social and Claris Chong's review of recent in situ cryo-ET chromatin studies and our opinion on an important future genomic direction is now published in Current Opinions in Structural Biology.

🏅 Congratulations to Sandra Schmid (@czbiohub) on receiving ASCB’s 2025 E.B. Wilson Medal! This award honors distinguished researchers for far-reaching contributions to cell biology over a lifetime in science—an achievement Sandra exemplifies. #ASCB #CellBiology
Really important development in improving contrast in the painfully low contrast images we get out of a cryo-TEM
Happy to share our latest publication, in which we show that the arrangement of nucleosomes around CTCF sites contributes to higher-order organisation of chromatin into TADs: www.embopress.org/doi/full/10....
For something different, tried this approach on something on the other end of the spectrum - in situ ribosomes from low SNR 2DTM data.
Used the U2OS-grid 9 dataset from EMPIAR-12459 (699 movies; doi.org/10.1016/j.mo...).
Blob pick & 2D after denoising gave 12k particles. 2-class HR-HAIR --> 3.3 Å
Our paper in Science is out! @souravagrawal.bsky.social, @rlynn.bsky.social, @susvirkar.bsky.social, and the rest of the team show human RPA is a telomerase processivity factor essential for telomere maintenance. This reshapes our thinking about telomerase regulation. www.science.org/doi/10.1126/...
