So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

The Great Oxidation Event (GOE) some 2.4 billion years ago established the oxygen-rich atmosphere that many living things ...

The recent paper's case for green oceans in the Archaean eon starts with an observation: waters around the Japanese volcanic ...

The model tracks the oxygen "turnover" — how much oxygen is produced and consumed — in inland waters since 1900. The ...

Scientists assumed most forms of life before the Great Oxidation Event didn't metabolize oxygen—but recent research suggests ...

Current warming accounts for up to 55 percent of the decrease in lake oxygen levels, the researchers estimate. If this trend ...

Climate change is revealing oxygen levels in lakes are decreasing faster than experts expected due to warmer temperatures.

they pump in nitrogen to reduce oxygen levels to nearly zero, simulating Mars' low-oxygen atmosphere. "The oxygen, of course, ...

Bacteria may have adapted to oxygen well before Earth’s atmosphere was saturated with it, according to a new study. Researchers who traced microbial evolution over billions of years – using machine ...

By increasing dissolved oxygen levels before the water reaches the turbines, more oxygen is absorbed into the water rather ...
