New research suggests that exposure to lower oxygen levels at high altitude may trigger biological changes that could benefit people living with diabetes.

Marine life receives its oxygen from warm water on the ocean's surface, but if there's no mixing with the colder water sitting below, then bottom-dwelling marine life, like lobsters, are unable to ...

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 ...

Oxygen is critical to life. When levels of oxygen change, it can have immediate and lasting impacts on a person's health.
