Astronomical #winter starts today. It's the shortest day of the year in terms of daylight with the sun starting to set later each day until Summer Solstice. The mosaic depicts the dancing Genii (protective spirits) of the four seasons. The Genius of winter is wrapped in a heavy cloak.🧵1/2 #Solstice

Thrilled to share that my first-author paper is now published in Nature Communications! 🎉 Huge thanks to my PI, Dr. Drew Bridges (@bridgesbio.bsky.social), my collaborators, and all the incredible lab members for their support throughout this project www.nature.com/articles/s41...

Excellent news for the end of the year! Our project on past and present bacteria with @jmuurine.bsky.social and great collaborators got funded. We will be looking for a postdoc for 2026-27 with expertise in bacterial genomics and/or molecular dating methods. If interested, DM me. Please share.

Now part of the University of York campus, Heslington Hall is a Grade II listed manor house dating from 1565–8, It was largely rebuilt between 1852-4. It was constructed for Sir Thomas Eynns, the Secretary and Keeper of the Seal to the Council of the North; and his wife Elizabeth.

Good morning from York and its majestic sky!

Can one map the genome-wide binding (1) and its protein partners (2) simultaneously from the same sample? Yes, one can. with CUT&ID ✂️🪪 Spearheaded — singlehandedly — by @annanordin.bsky.social No need of transgenesis, cloning and overexpression. Check it out, it's fast and its works.

Happy to share that our work on HLp, a bacterial histone from Leptospira perolatii, is now published in Nature Communications 🎉 In this study, we show that HLp forms stable tetramers that wrap ~60 bp of DNA, revealing a distinct histone–DNA organization in bacteria. www.nature.com/articles/s41...

We've come full circle! I began my postdoctoral career by identifying the peptidyl deformylase gene. Today, we show that half of bacterial species harbor multiple PDF genes (up to 7, for always a single Met-tRNA transformylase), and while the role of these PDFs ... academic.oup.com/mbe/article/...
