A new study from the University of Helsinki reveals how plant mitochondria draw molecular oxygen away from chloroplasts, an interaction not previously documented. The discovery sheds new light on how ...

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

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 ...

Finding oxygen in an exoplanet’s atmosphere is a clue that life may be at work. On Earth, photosynthetic organisms absorb carbon dioxide, sunlight, and water and produce sugars and starches for energy ...

Cyanobacteria, as they still exist today, were the first organisms to carry out photosynthesis and release oxygen. Produced in primeval oceans about 2.5 billion years ago, this oxygen accumulated in ...
