Sad to learn that David Botstein has passed away. Few people truly shape how you think and do science, and David was definitely one of them. I had a fun and influential time at Princeton with the Botstein, Kruglyak and co gangs. It shaped the way I do science.

@pratikkatte.bsky.social and I just released Lorax 🌲, a tool for interactive exploration of biobank-scale ancestral recombination graphs (ARGs).

If you’ve ever wanted to scroll across the ancestries of thousands of genomes… this is for you.

We were all very sad to learn the death of Pierre Capy. Pierre was a professor at University Paris Saclay, in the 1990s, he started a group working on the evolutionary genomics of transposable elements; this group is still very active today. He was a great teacher, mentor, and colleague.

How does the piRNA pathway solve the self vs. non-self problem? 🧬

Since piRNAs come from single-stranded RNA, how does the cell choose the right ones? For years, "piRNA clusters" were seen as THE privileged source. But are they really special and earmarked for biogenesis? (1/19)

Crushed to hear of Mark Batzer’s passing. He was the Boyd Professor at Louisiana State University. His influential research revealed how mobile elements shape the genomes of humans & other mammals. Mark’s personality, generosity & positivity were larger than life. He lifted everyone up. HUGE loss πŸ’”
