Japan's hot springs reveal how Earth's organisms survived the 'Great Oxidation Event' 2.3 billion years ago: Study A team ...

Microbial life on Earth still holds surprises. A recent study overturns our certainties about the emergence of oxygen respiration, revealing an adaptation much earlier than previously estimated. This ...

New research from the Earth-Life Science Institute at the Institute of Science Tokyo suggests iron-rich ecosystems played a ...

SAN FRANCISCO — Maybe the trigger for the rise of oxygen on Earth was nothing special. Maybe that oxidation didn’t need large tectonic shifts or the evolution of land plants. Instead, the circulation ...

The breath of oxygen that enabled the emergence of complex life kicked off around 100 million years earlier than previously thought, new dating suggests. Previous studies pegged the first appearance ...

It may have been unexpectedly easy for the air to become rich in oxygen. A new simulation of the rise of oxygen suggests that it was driven by the planet itself, and needed little help from living ...
