The amount of oxygen in the Earth’s atmosphere makes it a habitable planet. Twenty-one percent of the atmosphere consists of this life-giving element. But in the deep past — as far back as the ...

Scientists at Newcastle University have uncovered a source of oxygen that may have influenced the evolution of life before the advent of photosynthesis. While in high concentrations hydrogen peroxide ...

Although oxygen is now the most abundant element in our oceans and our atmosphere, comprising about 88.8 percent and 23.1 percent of the mass of the two, respectively, this wasn’t always the case. In ...

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 ...

A groundbreaking discovery of a mysterious oxygen source, termed “dark oxygen,” was made 5,000 meters below the ocean surface in the Clarion-Clipperton Zone. For years, scientists have puzzled over ...

A groundbreaking discovery has challenged the long-held belief that oxygen is produced solely by photosynthetic organisms. In their latest study, researchers have identified metallic minerals on the ...

What if it could solve all of our energy problems?

It's long been thought that photosynthesis was basically the only way that oxygen is naturally generated on Earth (some bacteria can also produce oxygen by breaking down nitrates). But a new study has ...

(WJW) – A new study says scientists have discovered “dark oxygen” at the bottom of the Pacific Ocean. According to the findings, published in Nature Geoscience, scientists have confirmed another ...

Scientists have shown the importance of hot temperatures in maximizing hydrogen peroxide generation from rocks during the movement of geological faults, and say it may have influenced the early ...
