Ocean Planet Biodiversity Genomics

The deep sea, covering approximately 65% of Earth’s surface, has long been considered a biological desert. In this extreme environment—particularly in the hadal zone at depths greater than 6,000 meters—organisms […]

Evaluating Serpentinization as a Source of Phosphite to Microbial Communities in Hydrothermal Vents

Previous studies have documented the presence of phosphite, a reduced and highly soluble form of phosphorus, in serpentinites, which has led to the hypothesis that serpentinizing hydrothermal vents could have […]

Were Earth’s Blue Oceans Once Green?

Scientists find evidence that our oceans used to be green, suggesting that this may be a sign of primitive life, including that on alien worlds.

Iron‐Oxidizing Bacteria Bloomed in Shallow‐Marine, Subtidal Environments 1.88 Billion Years Ago

The majority of large iron formations (IFs) were deposited leading up to Earth’s great oxidation episode (GOE). Following the GOE, IF deposition decreased for almost 500 Myr.

Understanding The Molecular Mechanisms Involved In Nitrous Oxide Reduction By Deep-sea Hydrothermal Vent Bacteria

Nitrous oxide (N2O) is the third most potent greenhouse gas after carbon dioxide and methane. It can also be oxidized by physical processes to form ozone-depleting substances. Atmospheric concentrations of […]
