These inland waters 'breathe' oxygen, just like we do. But a new study shows that we've been suffocating them during the last century, an era also known as the Anthropocene. The research reveals ...

A recent study finds most critically injured patients can recover with less supplemental oxygen than has previously been suggested. When a critically injured patient is admitted to the hospital ...

But before you step into one of those glass tubes breathing pure oxygen like you’re on a spaceship, here’s what to know — because this isn’t just deep breathing. Hyperbaric oxygen therapy ...

A key turning point was when oxygen accumulated in the atmosphere around 2.3 billion years ago. Scientists have used this oxygen surge and how microbes adapted to it to map out bacterial evolution.

Trees, plants and tiny plankton in the ocean all convert CO2 into the oxygen we breathe, but scientists say they’re not able to keep up with all the ongoing pollution from 150 years of burning ...
