Until now, it’s been very hard for scientists to establish a detailed timeline of the early evolution of bacteria.

Suppose humanity was faced with an extinction-level event. Not just high odds, but certain-sure. A nearby supernova will ...

Discover the evolution of bacteria through machine learning, DNA comparisons, and the Great Oxidation Event 2.4 billion years ...

supernovae occurring within 60 light-years of Earth could have stripped our planet's atmosphere of its protective ozone layer, exposing life to damaging ultraviolet radiation from the sun ...

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.

"If a massive star were to explode as a supernova close to the Earth, the results would be devastating for life on Earth," said Nick Wright, an astrophysicist at Keele University in the United ...

Machine learning techniques then assess whether those levels indicate the presence of life below. The work is published in ...

Electrical energy may also have sparked the beginnings of life on Earth billions of years ago, though with a bit less scenery-chewing than that classic film scene. But where did that organic ...
