Evolution of hunt, kill, devour in a Vibrio ecospecies
Great paper 'Molassodon' - genetically distinct ecospecies from typical V. parahaemolyticus, it has evolved a predatory strategy that devour other bacteria in viscous environments

A Vibrio-specific T6SS effector reshapes microbial competition by disrupting Vibrio bioenergetics Liu et al. report that a Vibrio-specific T6SS effector, TseVs, selectively disrupts Vibrio bioenergetics while sparing non-target microbes via an immunity-independent mechanism. This work reveals how ...

Quality over quantity: Small RNA pauses translation elongation to lift protein activity Small noncoding RNAs typically regulate the translation initiation of target mRNAs and thereby protein production. In this issue of Molecular Cell, Thongdee et al. discovered a novel regulatory mechanism where a bacterial small RNA modulates translation elongation and co-translational folding to alter protein activity without affecting protein abundance.

Advancing RNA phage biology through meta-omics Abstract. Bacteriophages with RNA genomes are among the simplest biological entities on Earth. Since their discovery in the 1960s, they have been used as i

I'm happy to share the first publication from my lab @hoerlab.bsky.social, now out in @narjournal.bsky.social! I take a look at the biology of RNA phages, focusing on how meta-omics methods are discovering new RNA phage families and bacterial defense strategies.
