The study links seawater microbiome composition to water-mass origin and transformation in the northeastern Barents Sea and St. Anna Trough, identifying distinct microbial signatures for different water masses.

This study shows H-NS silences bacterial antiviral immunity by compacting chromatin, and its deletion enhances phage defense in E. coli.

This paper characterizes OLD, an abortive immunity protein, revealing its structure and activation mechanism in response to phage replication and DNA defects in RecBCD-compromised cells.

The paper identifies phages infecting E. coli HS, shows their resistance to restriction via modifications, and links phage infection to a Klebsiella-like capsule.

The paper analyzes microbiomes of three sympatric Arctic sponge species, finding functional convergence and specialization within their symbiotic communities, with shifts linked to temperature changes.

The paper identifies additional tRNA targets of the AriB nuclease in the PARIS system and shows that phage-encoded tRNAs can inhibit this defense.

The paper identifies AcrIE9 as an inhibitor of E. coli K12 Type IE CRISPR-Cas system through a census of anti-CRISPR proteins in Enterobacterales.

This study elucidates the molecular mechanism of BREX anti-phage immunity by showing how BrxX methyltransferase recognizes DNA and forms an immune complex to protect against phage infection.

The paper shows that viral proteins activate PARIS-mediated tRNA degradation, and viral tRNAs rescue infection by preventing cleavage.

This study benchmarks DNA isolation methods for marine metagenomics by evaluating eight kits across three sample types, focusing on quality, contamination, and community composition.
