Scientists are trying to understand how complex life emerged on Earth about 2 billion years ago. Our microbial ancestors could be the key.

Ancient microbes tied to our earliest ancestors could use oxygen, reshaping ideas about how complex life began on Earth.

Life needs nutrients like nitrogen and phosphorus. But without the right balance of oxygen, these elements get locked away in planets’ cores.

Chronic wounds often spiral out of control because oxygen can’t reach the deepest layers of injured tissue. A new gel developed at UC Riverside delivers a continuous flow of oxygen right where it’s ...

For decades, scientists have believed that complex life began when two very different microbes joined forces, eventually giving rise to plants, animals, and fungi. But one major puzzle remained: how ...

Learn how oxygen’s early rise could have given complex life the energy boost it needed to evolve.

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

Researchers have developed a battery-powered oxygen gel that accelerates the healing of chronic diabetic wounds ...

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 ...
