Finally, we propose a model in which chromatin is self-organising based on histone acetylation and nucleosome depletion. We hypothesise that active cis-regulatory elements may contact one another at or above a layer of acetylated nucleosomes.

Do we need LLMs to predict epigenomes from DNA—or is biophysics enough? 🧬
IceQream (IQ) is a biophysics-based framework that predicts epigenomes with SOTA-level accuracy—and is fully explainable.

Just received a notification that our university is renegotiating #openaccess agreements with the “big five” publishers (Springer, Elsevier, etc), and it is highly likely that we will lose some of these agreements. If we do, this will be a big problem since we do not have budgets to pay OA fees

Anyone have any experience of Element AVITI sequencing for methylation profiling by WGBS or EM-sequencing?
Useful to know what other people's experience is as local facility have one and cheaper than Illumina for short read sequencing.

Interesting paper from Gernot Längst & Co. They calculated nucleosome repeat length in Plasmodium falciparum, the malaria-causing parasite, and showed that it follows a smooth continuous function of time (the numbers on the X axis below are hours post-invasion) www.biorxiv.org/content/10.1...
