For now, life thrives on our oxygen-rich planet. But Earth's atmosphere won't always be so welcoming. In fact, scientists predict that Earth will eventually undergo a drastic atmospheric shift—one ...

South Africa’s exceptionally preserved ancient rocks hold key evidence for the rise ofatmospheric oxygen. Within them, researchers see the disappearance of sulfur mass-independent fractionation, ...

Life on Earth may have learned to breathe oxygen long before oxygen filled the skies. MIT researchers traced a key oxygen-processing enzyme back hundreds of millions of years before the Great ...

Researchers uncovered that trace compounds like nickel and urea may have delayed Earth’s oxygenation for millions of years. Experiments mimicking early Earth revealed how their concentrations ...

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 ...

The key enzyme behind photosynthesis isn’t actually all that great at its job. Plants eat sunlight and air to make life. But the key enzyme behind it all, called RuBisCO, isn’t actually all that great ...

In 2020, scientists reported the detection of hematite, an iron oxide mineral otherwise known as rust, distributed through the higher latitudes of the moon, particularly on the nearside. This came as ...

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say. When you purchase ...
