I had the privilege to meet artist Mary Griffiths. Mary got inspired by Hi-C maps and over zooms we spoke about Hi-C maps, patterns and drawings. Mary’s Hi-C inspired art has been exhibited eg the Royal Academy. We wrote this piece about this art-science collaboration

Seeing into Hi-C: How our scientific connectivity revealed the close connections in our DNA to be a work of art
Scientific data can be beautiful. An example where the data itself have a particularly striking appearance even before any scientific meaning has been ascribed

GWAS has been an incredible discovery tool for human genetics: it regularly identifies *causal* links from 1000s of SNPs to any given trait. But mechanistic interpretation is usually difficult.
Our latest work on causal models for this is out yesterday:

Ribosomal RNA (rRNA) genes are found in hundreds of copies in the human genome.
Do sequence variations in these paralogs change the ribosome function? Yes!

An epic story and a must read. This is really beautiful work to understand the most amazing monthly regeneration event - menstruation. The authors reconstitute this process in mice (which don’t normally menstruate) allowing important new insights. Will also be a powerful model for future work.
Lab’s 1st preprint!
Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate.
@cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation.
He is on the job market!

We used it to uncover how the endometrium organizes and sheds during menstruation. 🧪
