Divergence and conservation of the meiotic recombination machinery - Nature Reviews Genetics In this Review, the authors describe the evolutionary conservation and divergence of the meiotic recombination machinery, focusing on proteins that are required for meiotic double-strand break formati...

For more of our thoughts on the topic I also want to highlight again our review article, where we discuss many of the questions that led to this project: www.nature.com/articles/s41...

The main project of my postdoc with @spo11rulz.bsky.social is now available on bioRxiv! By systematically integrating structural information with molecular evolution analyses, we gained new fascinating insights into the evolution of key meiotic recombination proteins: www.biorxiv.org/content/10.1...

Check this out. @artermeret.bsky.social and @spo11rulz.bsky.social cleverly used protein structural information to pinpoint the action of selection and evolutionary constraints in 3D space on meiotic recombination proteins.

Please repost: I'm looking for suggestions for activities (scientific, social, team-building, whatever) for a lab retreat. What worked well in retreats you've been to?

(I put this on Twitter a while ago and got some great responses, but lost the info when I deleted that account.)

"I have a comment and a question. The comment is just to clarify: of course, as everyone knows, that inscription is not in Elvish, it's the Black Speech of Mordor." Scott never forgave me.

2) At the start of an absolutely fabulous talk about three new RING genes his group had discovered and named Narya, Vilya, and Vanya after the three Elven rings in LOTR, Scott showed the inscription from the One Ring and described it as being in Elvish. After the talk, I raised my hand...

Two Scott stories that stick in my head, both from talks at Meiosis Gordon conferences. 1) After mentioning something about Gregor Mendel's son, a pause, then "Mendel was a great geneticist but terrible monk"

Sadly, our colleague and friend Scott Hawley passed away this morning. He was an irreplaceable presence and force for good in the meiosis an Drosophila communities and will be sorely missed.

Feeling very lost today with the news of the passing of my undergrad advisor Scott Hawley. He had a huge impact on the field and on me personally. He was the first person to see me as a scientist and gave me the confidence to apply to grad school. I am so grateful to be a part of his legacy.
