Earth's oxygen boom: How nickel and urea in early oceans shaped microbial life and set the stage
The appearance of oxygen in Earth's atmosphere was a turning point in the history of our planet, forever transforming the ...
Ancient hot springs in Japan reveal how microbes adapted to Earth’s first oxygen, offering insights into early life.
Oxygen-producing cyanobacteria triggered ... Thus it's possible that the microbes carry out a "cryptic" sulfur cycle that we do not yet understand. These findings offer a new window into how life ...
“The lifespan of oxygen-rich atmospheres may be shorter than we previously thought,” Georgia Institute of Technology’s Christopher Reinhard said, echoing the subtle sense of urgency that now governs ...
When did the Earth reach oxygen levels sufficient to support animal life? Researchers have discovered that a rise in oxygen levels occurred in step with the evolution and expansion of complex, ...
The Great Oxygenation Event marked a massive transition in life on Earth, when oxygen became plentiful and organisms suddenly ...
Billions of years ago, Earth’s atmosphere was hostile, with barely any oxygen and toxic conditions for life. Researchers from the Earth-Life Science Institute studied Japan’s iron-rich hot springs, ...
Deep-sea researchers have launched a groundbreaking project to investigate "dark oxygen"—a form of oxygen produced in total darkness on the ocean floor. The initiative follows last year's discovery of ...
We think of oxygen as life, sustenance, a literal breath of fresh air. But it's actually a very reactive element. Anyone who's burned a log has witnessed this firsthand. So why do so many life-forms ...
New research reveals when oxygen flips from stable to reactive, "singlet" form connecting the chemistry of life with ...
