(1/9) Join us in Bern, Switzerland (8–11 Feb 2026) for our EMBO Workshop on Molecular Mechanisms of Selfish Elements and Strategies!
Organized with Tanja Schwander, Laura Ross (@laurarossevo.bsky.social) and Axel Imhof.

It's finally out! This paper took quite a while but I'm so excited to share now! For anyone who studies sex chromosomes, take note: we found a rare "slower X"! (dN/dS_X < dN/dS_Autos) 👀
Great introduction to one of my favorite study organisms, and to promote our recent study into how their unusual genetics affects patterns of molecular evolution.
Amazing sperm work on a great understudied Lepidoptera system! Congrats @ajmongue.bsky.social
Reminder that the registration for this meeting closes today. We have a great list of speakers and participants, do not miss out!
Thanks @cecilecourret.bsky.social for this great perspective highlighting our recent paper on B chromosomes
Please share widely! Abstract submissions open for the 2026 Jacques Monod conference: Ecology and evolution of host-parasite interactions in a changing world! Held in beautiful Roscoff France from November 2- 6, 2026. Abstracts submission deadline : June 6

Very excited that it's finally coming out!
Did you know that many organisms delete parts of their genome during development? To know more please join us at the Roscoff meeting on "Mechanistic and Evolutionary Basis of Programmed DNA Elimination" Sep21- 25, 2026. Please share! cjm.sb-roscoff.fr/en/conferenc...
X chromosomes evolve faster than autosomes, but confounding factors make this a difficult phenomenon to study. Utilising the unusual sex determination system of Sciaridae flies, this study finds a slo...

Certain genes, chromosomes, organelles, or entire sets of chromosomes can bias their transmission to the next generation, propagating themselves at the expense of the rest of the genome. Referred to …

Re-upping this thread on PGE in mealybugs because the results are finally published in Molecular Ecology:

Pre-print and weird repro thread time!
I've posted here about scale insects a lot, but ~half of my research is on Lepidoptera. My lab is developing bagworm moths (Psychidae) as models for comparative genomics.
You probably know them like you see in the pics below: caterpillars that make cases.

Trends in Genetics
Most studies of sex-biased genes explore their evolution in familiar chromosomal sex determination systems, leaving the evolution of sex differences under alternative reproductive systems unknown. He...
Wow, lots of new followers this week! To celebrate and (re)introduce myself, I want to share one of the weird reproductive systems my lab works on: Paternal Genome Elimination in mealybugs. If you have house plants, maybe you know these waxy little pests already. But do you know their genetics?
