This study isolates two Hodarchaeales strains, closely related to the eukaryotic common ancestor, revealing their syntrophic, anaerobic, and oxygen-tolerant physiology and genomic features.

The paper investigates CO and H2 as energy sources for microbes in the Mariana Trench, finding higher H2 oxidation rates at depth compared to CO.

The paper establishes a tripartite co-culture system to study defensive mutualism between a Nanobdellati symbiont and its host, revealing glycan-mediated protection against viral infection.

The paper reports the discovery of a chemosynthetic community at a serpentinite-hosted seep on Quaker Seamount, identifying 15 species including six endemics.

The paper shows direct CO fixation to acetyl-CoA in archaeal and bacterial Wood-Ljungdahl pathways under hydrogenogenic growth using 13C tracer-based metabolomics.

This study uses population genomics to identify genetic groups in the scaly-foot snail, highlighting conservation priorities amid deep-sea mining threats.
