Many of you may have received pessimism from me over the years about using Hi-C to predict distal regulatory effects, mired with paradoxical optimism that cohesin loop extrusion is key.
Well, the story behind all that rambling is finally ready to be told.
Ever wanted to watch chromosomes fold?
lefsim simulates loop extrusion live in your browser. Add, remove and drag CTCF sites around, watch contact maps emerge, and more.

Underneath is a blazing fast Rust engine with Python and JavaScript packages, for research-scale use.

pretty interesting tool: Oxbow makes genomic data ready for high-performance analytics.

Really enjoyed presenting our genomics talk "Declare, don't parse" at #SciPy2026 with Conrad Bzura!
Slides here: abdenlab.org/scipy26
Also excited to kick off a new initiative with @jmschreiber91 the polars-bio team at Warsaw University of Technology: composeq.dev/
Interested in a new substrate for agent-ready genomics? Get in touch!

I mean, most of bioinformatics data is just tabular data with bad conventions, formats.
@nv1ctus is pushing a pretty good software to make things better with bioframe and oxbow :)
I’m excited to be co-chairing the Biological & Medical Sciences track for the #SciPy2026 conference 🎉 in July, along with Aishwarya Chander and Jacqueline Valeri. scipy2026.scipy.org/
