This study integrates surveillance methods to profile AMR genotypes and phenotypes across diverse environmental and clinical samples, revealing high diversity and mismatches between genotype and phenotype.

This study shows that Antarctic soil bacteria can consume trace gases like H2 and CO across wide temperature ranges, with potential increases in activity under future climate scenarios.

This study identifies aridity as the primary driver of microbial community structure and biogeochemical activities in deserts across seven continents.

This study investigates microbial colonization in glacial forelands, finding that metabolically flexible bacteria drive early succession and create hospitable conditions for later colonizers.

This study identifies aerotrophy as a primary energy source in caves, revealing microbial use of atmospheric trace gases for continuous primary production.

The paper identifies microbial communities in wetland tree barks that mediate methane and hydrogen cycling, showing they can both mitigate and emit climate-active gases.
