Archaea are often surrounded by bacteria. But is there ever active conflict between the two? Can archaea kill bacteria? If so, how do they do it?

Work by @romainstrock.bsky.social shows that some archaea can kill bacteria by secreting peptidoglycan hydrolases. journals.plos.org/plosbiology/...

Together, we highlight how, 50 years on, the nucleosome still has surprising and unexplored roles in orchestrating the functional genome. Who knows what's left to be uncovered.

Moreover, evolution has used this repeatedly, as H2A.Zs from across eukaryotic diversity have acquired a physical interaction with the transcription elongation factor Spt6, driving its recruitment to chromatin and increasing transcription processivity.

We show that histones are more than just barriers to transcription--they can also directly interact with the transcription apparatus through their core domain, shaping its activity.

Happy to share our new paper out today in @cp-cellreports.bsky.social in collaboration with @tobiaswarnecke.bsky.social @akihisaosakabe.bsky.social about how evolution can do big things with small changes. www.sciencedirect.com/science/arti...
