Really important development in improving contrast in the painfully low contrast images we get out of a cryo-TEM
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/...

Telomerase counteracts telomere shortening by repeatedly adding DNA repeats to chromosome ends. We identified the replication protein A (RPA) heterotrimer as a telomerase processivity factor critical ...
In a series of 3 papers and preprints, we’re thrilled to share with you the working laser phase plate. In collaboration with research led by Holger Müller at UC Berkeley, this is a huge innovation in imaging to make small and faint objects inside cells visible. bit.ly/4vK9LVn

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
