Hello Bluesky!
Does Nₑ really explain mutation rate (μ) or genome size (GS) in vertebrates?
We find the apparent Nₑ–μ link in Bergeron et al. (2023) is a “back-door” path via generation time, and GS is decoupled from both Nₑ and life-history traits.

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)

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.
Pierre Capy était un généticien, un drosophiliste, un acteur majeur dans l'essor de la génétique des éléments transposables en France.
Très impliqué dans l'administration de la vie scientifique, il a aussi été directeur du laboratoire LEGS (actuel @EGCE), et un des fondateurs en 2016 de @IDEEV.
