Bah, who needs cohesin if you're at the right place (near). Grover once taught us the difference between near and far (my favourite Sesame Street piece), and now amazing work from @elphegenoralab.bsky.social led by @karissalhansen.bsky.social shows us how: www.science.org/doi/10.1126/...
Synergy between regulatory elements can render cohesin dispensable for distal enhancer function

Unrelated to mim itself, but this is also the first preprint I've prepared in @typst.app rather than LaTeX. It was soooo much nicer. Folks; what are we doing? Why don't our journals accept manuscript sources in Typst!
Ok; mim (github.com/COMBINE-lab/...) preprint submitted! Excited for folks to see it and share thoughts. The key takeaway; mim allows the quick, one-time, building of a small auxiliary index that then allows scaling gzipped FASTQ parsing linearly in # of threads. 1/2

To probe gene-scale chromatin physics, we built 96-mer (20 kb) arrays with defined histone marks. Combining single-molecule tracking, AFM imaging, and developing in vitro Hi-C, we saw how specific modifications dictate chromatin structure and dynamics. www.science.org/doi/10.1126/...
Gene-scale in vitro reconstitution reveals histone acetylation directly controls chromatin architecture
Reconstituting 20-kb chromatin shows that tuning acetylation alone reshapes its folding, dynamics, and contact domain formation.

Single-cell analysis of fruit fly motor neurons shows that RNA editing occurs at widely varying rates, contributing to neuronal diversity and potentially influencing neural function and development. doi.org/hbb3pz
RNA editing study finds many ways for neurons to diversify
All starting from the same DNA, neurons ultimately take on individual characteristics in the brain and body. Differences in which genes they transcribe into RNA help determine which type of neuron they become, and from there, a new MIT study shows, individual cells edit a selection of sites in those RNA transcripts, each at their own widely varying rates.

Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9
Adenine DNA methylation associated with transcriptionally permissive chromatin is widespread across eukaryotes - Nature Genetics
Long-read sequencing in 18 unicellular eukaryotes reveals that 6mA is widespread across eukaryotes and is enriched at transcriptionally permissive regions, which are also marked by H3K4me3.
