New research from a University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led science team provides new insight into one of the world's most diverse and extensive ecosystems of living microbes.

How did life begin? This is one of the most fundamental questions scientists puzzle over. To address it, they have to look not just back to the primordial Earth, but out into space.

At the bottom of an icy Antarctic lake, a thin, slimy layer of bright green microbes is generating a tiny oasis of oxygen that might give a picture of what early Earth looked like before oxygen became common in the atmosphere.

Plant biologists agree that it all began with green algae. At some point in our planet's history, the common ancestor of trees, ferns, and flowers developed an alternating life cycle--presumably allowing their offspring to float inland and conquer Earth

NASA-funded researchers at the Georgia Institute of Technology are tapping information found in the cells of all life on Earth, and using it to trace life's evolution.

Water covers more than two-thirds of Earth's surface, but its exact origins are still something of a mystery.

UCLA geochemists have found evidence that life likely existed on Earth at least 4.1 billion years ago -- 300 million years earlier than previous research suggested.

Inspired by previous work on chemistry's 'water problem' and 'asphalt problem,' a team of researchers has provided new insight into the conditions in which nucleosides combine with phosphate to form nucleoside phosphates, a key set of molecules found in RNA.

Earliest Jurassic Corals Discovered

Five times in Earth's history mass extinction events have wiped out up to 90 percent of global life.

Looking at The Limits for Life

Biological processes on the Earth operate within a parameter space that is constrained by physical and chemical extremes.
