Since the Nobel prizes were first awarded in 1901, few women have been recognized in the categories of physics, chemistry and physiology or medicine. In this year’s Nobel run-up, Nature shines a spotlight on female winners — and invites you to test your knowledge. 🧪

For those of you who, like me, missed the Vatican #EvoDevo: www.pas.va/en/events/20..., don't worry, there will be a more earthly local version next week (Friday) in Cambridge Dept of Zoology, program here: londonevodevo.co.uk. Can't promise cardinal vestments in the background though.

🚨 We discovered a new mode of Hox gene regulation in annelids! 🪱 A distal enhancer acts as a "global control region", lifting Hox genes from Polycomb repression. This is reminiscent of Hox gene control in vertebrates, but the two modes likely evolved convergently. www.biorxiv.org/content/10.6...

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.

Chaetognaths have lost gene body methylation and shifted #5mC back to Transposable Elements. This reversion to the ancestral state is coupled with a simplification of DNMT3 architecture. We posit that trans-splicing might compensate. It is an honour to have contributed to this 20y struggle ⛰️.
