Finally, my paper is out! It shows how bacteria can utilize their CRISPR immunity against transducing phages to turn them into "pollinators". This way bacteria can speed up their own adaptation through recombination by two orders of magnitude compared to mutations, and they do so when starving!

@pavelpayne.bsky.social et al. show that bacterial herd immunity can promote homologous recombination, suggesting bacterial immune systems can shape molecular evolution not only by blocking infection but also by regulating genetic exchange 🔗 academic.oup.com/mbe/article/... #societyjournal #evobio

I'm really excited to share my latest research paper with the world. It has been a long and bumpy road to finish this project and get it published, but finally, it is out!

Do bacteria have sex? ISTA scientists @pavelpayne.bsky.social and Călin Guet have uncovered a process resembling sexual reproduction that occurs when the gut bacterium E. coli is close to starvation. Read more: ista.ac.at/en/news/bact...

Preprint finally out! I show that eco-evo feedback can drive a tipping point where genetic drift overwhelms adaptation. This can result in a contraction of a species' range border or range fragmentation. Fragmentation is abrupt and arises readily under rapid temporal change. doi.org/10.1101/2025...
