NASA's Carbothermal Reduction Demonstration (CaRD) project has completed an important step toward using local resources to support human exploration on the moon. The CaRD team performed integrated ...

Scientists have discovered a surprising source of oxygen on the deep ocean floor, challenging the long-held belief that sunlight is essential for its production. Research in the Pacific's ...

New research from ETH Zurich challenges the long-held “follow the water” rule in the search for extraterrestrial life. Scientists argue that a planet’s habitability depends on a narrow chemical ...

The aim of the book “Oxygen atom transfer reactions” is to outline some recent developments in the studies of oxygen atom transfer mechanisms in catalytic oxidation reactions based on several ...

The new plot twist is that in order to keep enough nitrogen and phosphorus near its surface, a planet has to start out with ...

Oxygen fills the air today, but for most of Earth’s early history it barely existed. Scientists say the atmosphere did not hold steady oxygen until about 2.

For the first time, researchers have managed to isolate and directly observe individual oxygen atoms inside liquid water, catching a substance that usually hides behind the familiar H 2 O formula in ...
