The Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

Researchers discover how low-oxygen environments at high altitudes reduce diabetes prevalence, revealing potential new treatments that use red blood cells as 'glucose sponges'.

A new study suggests that some of the world’s oxygen-deprived oceans could eventually regain higher oxygen levels in the ...

Hyperbaric Oxygen Therapy is a medical treatment that increases blood plasma oxygen levels 10 to 20 times higher than normal to assist the body in healing its damaged tissues.

Blood oxygen levels refer to the amount of oxygen circulating in the blood. Normal blood oxygen levels fall between 75 and 100 millimeters of mercury (mm Hg) on arterial blood gas (ABG) test results.

Reducing oxygen levels in critically ill children on mechanical ventilators in intensive care could save tens of young lives each year, finds a new study led by researchers at UCL and Great Ormond ...

In a 2023 paper on hypoxia and glucose metabolism, our lab showed how organisms rewire their metabolism to adapt to low oxygen levels—such as those found at high altitudes. One of the most striking ...

Tiger Iron formed when in the sea dissolved iron reacted with free oxygen produced by the first photosynthetic life forms on Earth. For the first 2 billion years of Earth's history, there was barely ...

Smartwatches can measure everything from heart rate to sleep quality, but one health metric has become particularly relevant over the past two years: blood oxygen saturation. Two of the world's ...
