A dangerously low oxygen level—usually below 92%—can cause shortness of breath, confusion, chest pain, or fainting. It’s often triggered by lung or heart conditions like COPD, asthma, or heart ...

Earth’s atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time ...

"Now, we wanted to get a more dynamic picture of how proteins are regulated when oxygen levels are too high or too low," Chen says. To do so, the team exposed mice for several weeks to air with oxygen ...

Researchers have found evidence that low oxygen levels in tumors could actually enhance some of the body's immune responses against cancer, in contrast with the general paradigm that hypoxia ...

A recent study explored one possible cause -- hyperoxia or high concentrations of oxygen given to such patients during surgery -- as opposed to doses more similar to air. The study concluded that ...

Janay Reece came back home to Baltimore to join WJZ in August 2023. Before coming back to the Charm City, Janay was a morning anchor and reporter for WDBJ7 in Roanoke, VA. She joined the WDBJ7 morning ...

Scientists have long known that people living at high altitudes, where oxygen levels are low, have lower rates of diabetes than people living closer to sea level. But the mechanism of this protection ...

Researchers at the Francis Crick Institute have shed light on how cancer cells survive in the first few hours after being cut off from a supply of oxygen. Published in The EMBO Journal, this finding ...
