I am still wrapping my head around the amazing week that I had first at our @spaam-community.bsky.social conference #SPAAM7 followed by 3 days of @isba11.bsky.social in Torino.
A conference that ended with a prestigious award. I am very grateful and honoured @isbarchaeology.bsky.social

Very happy to see this one out: doi.org/10.1093/molbev/msaf192
Here, we assessed the contribution of natural transformation to the acquisition of novel genes. See preprint thread. @molbioevol.bsky.social #microsky #evobio

🦠🧍‍♀️From bacterial to human immunity.

We report in @science.org the discovery of a human homolog of SIR2 antiphage proteins that participates in the TLR pathway of animal innate immunity.

I learned today that the NSF SBE conference I’m co-organizing in DC in eleven days has been cancelled. This seems to be related to he return of DOGE at the NSF: www.science.org/content/arti...

NSF halts grant awards while staff do second review

Action comes after DOGE team arrives at science agency

Phage satellites are now known to be very diverse, numerous and ancient. They pose many evolutionary, ecological and mechanistic questions. Lots of fun in perspective!
Great pleasure to write this review to show it, with @jrpenades.bsky.social @dbikard.bsky.social Kim Seed & John Chen.

New online! Genetics, ecology and evolution of phage satellites

Genetics, ecology and evolution of phage satellites

Nature Reviews Microbiology, Published online: 27 March 2025; doi:10.1038/s41579-025-01156-zIn this Review, Penadés et al. explore the genetics, potential origins and life cycle of phage satellites, and they discuss the impact of these elements on the evolution of other mobile genetic elements and their host bacteria.
