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.

Bacteria Found Alive in Earth's Most Extreme Environments for the First Time Hold Clues to Life on Other Planets Published Dec 20, 2017 at 4:37 PM EST Updated Dec 21, 2017 at 10:17 AM EST ...

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.

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.

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.

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

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.

Bacteria found on asteroid was actually Earthly contamination, scientists report A new study of samples from Ryugu found that microorganisms can avoid even stringent contamination controls ...

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 ...
