Our new preprint is out＠bioRxiv: biorxiv.org/content/10.1101/…
@MasaAShimazoe et al. reveal that linker histone H1 acts as a liquid-like "glue" to organize chromatin in living cells. 🎉 Fantastic collab with @rcollepardo, Charlie Phillips, @janhuemar and others—huge thanks! 🙌 1/2

Top 5 advances in medicine this week (🧵)
1. Vitamin C modifies the amino acid, lysine, to form VitCyl-lysine
This is a novel post-translational modification: it promotes immunity and (in mice!) boosts anti-PD1 immunotherapy to kill cancer
Whether vitamin C can also boost immunotherapy in humans isn't yet clear, but trials are ongoing

Marjorie Courtenay-Latimer was born #OTD in 1907.
In 1938 she found a very unusual fish in a market - a coelacanth, thought to be #extinct. It was later named after her with the generic name of Latimeria.

Centromere evolution isn't a sudden switch!
Our study shows centromere transitions are a step-by-step process driven by a combination of drift and selection. Discover how the kinetochore interface shapes this gradual change in our new preprint doi.org/10.1101/2025.01.16.6… 🧵(1/8)
