For anaerobic bacteria, there are sets of reactions they do perform, including turning other compounds into things like phosphine. They turn carbon dioxide into methane — CO₂ to CH₄.

The bacteria-first theory, also known as the reductive hypothesis, picked up support in 2003 when French researchers discovered a giant virus in the sludge of a water tower in Bradford, England.

Experiments performed on the International Space Station have suggested that bacteria from Earth could be used to extract useful minerals on the moon or Mars.

Two life forms living together helped spark the evolution of all complex life. By learning to appreciate this process more ...

A type of bacteria that is highly resistant to radiation and other environmental hazards survived outside of the International Space Station for three years, according to a new study.

Life on Earth was dominated by simple bacteria up until about 650 million years ago when more complex forms of life suddenly took over. The reasons why this happened were something of a mystery.

Phosphine, a simple molecule consisting of three hydrogen atoms and one phosphorus atom, is thought to be created by anaerobic bacteria on Earth. Thus, it can be detected emanating from sewers and ...

Scientists estimate that the earliest biological entities began to appear on Earth more than 4 billion years ago. "There was a sort of primordial soup from which certain organic molecules were ...
