Researchers have revived microalgae that had been dormant for millennia in the sediments of the Baltic Sea. This ...

Scientists have helped to construct a detailed timeline for bacterial evolution, suggesting some bacteria used oxygen long before evolving the ability to produce it through photosynthesis.

Scientists assumed most forms of life before the Great Oxidation Event didn't metabolize oxygen—but recent research suggests ...

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely ...

Girguis, a professor of Organismic and Evolutionary Biology at Harvard, specializes in biochemistry and ecological physiology ...

Earth's oceans may have displayed a very different color several billion years ago. This hypothesis emerges from a recent ...

Researchers have successfully revived algae that remained dormant underneath sediment at the bottom of the Baltic Sea for ...

The revived organisms resumed their biological activities as if they hadn't been without oxygen and light for thousands of ...

Scientists have spent decades genetically modifying the bacterium Escherichia coli and other microbes to convert carbon dioxide into useful biological products. Most methods require additional carbon ...

Microalgae are tiny organisms that convert energy from sunlight into fuel. The arctic ecosystem depends on them. In springtime, the algae bloom brilliant shades of green and draw tiny crustaceans, ...

Carbon dioxide (CO₂) pollution drives climate change, warming the planet and threatening human survival. Plants naturally ...

Imagine the world’s oceans with their beautiful blue color. Now, imagine that the same oceans were green. This is the intriguing possibility suggested by new research from Nagoya University in Japan.
