A Coma Pattern-Based Autofocusing Method Resolves Bacterial Cold Shock Response at Single-Cell Level

The study introduces LUNA, a novel coma-pattern-based autofocusing method that achieves nanoscale precision to overcome temperature-induced focus drift, thereby enabling the first single-cell resolution of bacterial cold shock response dynamics and revealing a continuous growth adaptation process that reconciles previously conflicting batch culture observations.

Occurrence of Carbapenem-resistant Enterobacterales in swine wastewater in Shandong Province, China

This study reveals that swine wastewater in Shandong Province, China, serves as a reservoir for diverse, multidrug-resistant carbapenemase-producing *E. coli* (including *bla*NDM, *bla*OXA-48-like, and *mcr*-1 co-harboring strains) with evidence of clonal spread across multiple cities, highlighting the critical need for continuous surveillance to protect human and environmental health.

From genomic decay to functional advantage: Traits of a persistent, thermally beneficial coral probiotic

This study demonstrates that an evolution-guided selection approach identifying a *Ruegeria* strain (MC10-B4) with genomic signatures of host dependency yields a persistent coral probiotic that enhances thermal tolerance through unique mechanisms like siderophore-mediated iron acquisition and a distinct motility-to-sessility reprogramming response, validating a strategy that prioritizes innate colonization potential over conventional laboratory traits.

Virulence and antimicrobial resistance features among clades of Escherichia coli ST131 strains causing community-acquired urinary tract infection in Rio de Janeiro, Brazil

This study characterizes a collection of 133 Escherichia coli ST131 strains from Rio de Janeiro, revealing that subclade C2 exhibits high multidrug resistance and ESBL production while clades B and C2 possess distinct virulence profiles, collectively suggesting that Clade C strains are the primary drivers of ST131 dissemination and persistence in the region.

Redox distribution of Asgard archaea and co-occurring taxa in microbial mats from an early Proterozoic ecosystem analog

This study analyzes redox-stratified microbial mats from an early Proterozoic analog in Ethiopia to demonstrate that Asgard archaea thrive in sulfate-reduction zones through syntrophic interactions with sulfate-reducing bacteria, utilizing specific metabolic adaptations like oxygen-tolerant hydrogenases and methanogenesis while lacking aerobic respiration.

Dispersal, adaptation and persistence of H5N1 in the sub-Antarctic and Antarctica

This study utilizes 104 novel viral genomic sequences to demonstrate that the H5N1 virus rapidly dispersed across 8,000 kilometers of the sub-Antarctic and Antarctica via long-distance movements of petrels and albatrosses, causing devastating impacts on marine wildlife while accumulating mammalian-adaptive mutations that raise concerns about its potential endemization and further evolution.
