The phage nucleus synergizes with an anti-defense protein to resist bacterial immunity
Morgan et al. show that a phage-encoded protein functions as an antitoxin to counter DarTG2-mediated phage defense. They further explore the interplay between this anti-defense protein, the phage nucleus replication compartment, which encloses chimallivirus genomes, and the DarTG2 phage defense system.

Bacteriophages are normally classified as either virulent or temperate. Reality is, of course, more complicated! Here we show many bacterial isolates contain non-temperate phages that can persist through restreaking. Thanks to all co-authors for such a great collaboration!

My friend Naftali Kaminski is an Israeli physician, a professor at Yale, and the child of Holocaust survivors. For me he is a model of absorbing his parents' stories intensely, looking the horror of the 20th century in the eyes, and drawing the lesson of radical empathy for the suffering of others.

This is why I always have to filter my BLAST results. Nice analysis and interesting questions about the persistence of lytic phages in host populations. I suspect for chimalliviruses it's a product of longer latent periods and low infection efficiencies in many hosts.

"That telomere phages are so prevalent means that they are a selective force, one that we know little about. We now want to understand how the telomere-toxin is secreted and also understand how this ‘telocin’ wheedles its way into unsuspecting bacterial neighbors” www.science.org/doi/10.1126/...
Telomere bacteriophages are widespread and equip their bacterial hosts with potent interbacterial weapons
Klebsiella host strains infected with telomere phages can grow to be the dominant lineage in mixed populations.

Anyone who puts a reddit AMA on their CV should be immediately disqualified from holding a policy position.
Thread on Jay Bhattacharya's weak scientific bona fides. Let's look at his CV. Too many scientists are saying "Bhattacharya has NIH funding, he can't be that bad." No. He wants revenge. He hasn't gotten an NIH grant since 2017, and the two grants then were only as a stats/econ consultant.
Flashy words like "revolutionize" are thrown around quite liberally in our field. In this case though, I can't think of a more appropriate word. This stuff is 🔥🔥🔥.
