The paper examines how oxygen and sulfide affect microbial N2O production and consumption in coastal sediments under seasonal redox changes, finding that sulfide can enhance or inhibit N2O consumption depending on concentration.

The paper introduces ArchaeaHQ, a curated database of 21,644 archaeal genomes with quality control and metadata, to improve representation in computational biology tools.

This study expands the diversity of Asgardarchaeota, revealing metabolic features suggesting aerobic respiration in the Asgard-eukaryotic ancestor.

This study investigates the metabolic flexibility of Ca. Methanoperedens and its interactions with sulfate-reducing bacteria in Lake Cadagno sediments using metagenomics and incubations.

The paper examines nitrogen dynamics in coastal waters with varying redox conditions, finding that long-term euxinia reduces ammonium removal by inhibiting nitrification.

The paper identifies and characterizes mini-bacterioferritin, a novel ferritin-like protein from an anaerobic methane-oxidizing archaeon, revealing its structure and evolutionary relationships.

This study identifies mobile genetic elements and defense systems in Asgard archaea, revealing their role in shaping genetic diversity and evolution.
