Glad to share the work of @yli18smc.bsky.social and co on Lamassu, a bacterial defense system related to Rad50/Mre11 (RM). While RM carefully trims DNA ends for repair, Lamassu chops up the host chromosome. Our study reveals how it is regulated to minimize damage, activating only during infection.

Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?
Today, we report the discovery of telomerase homologs in a family of antiviral reverse transcriptases, revealing an unexpected evolutionary origin in bacteria.

Diverse and abundant phages exploit conjugative plasmids - Nature Communications
Some phages use plasmid-encoded conjugation proteins as receptors to infect their bacterial hosts, making their host range dependent on horizontal transfer of the plasmid. Here, the authors present a method for identification of new plasmid-dependent phages, and find that they are common and abundant in wastewater and their genetic diversity is largely unexplored.
