More than 3.5 billion years ago, the Earth was not the hospitable world we know today. The atmosphere lacked oxygen, the seas were acidic and rich in iron, and volcanic activity roared across a barren ...

Earth was not always the blue-green world we know today: the early Earth's oxygen levels were about a million times lower than we now experience. There were no forests and no animals. For ancient ...

A new study co-authored by Texas A&M University geologist Dr. Michael Tice has revealed potential chemical signatures of ancient Martian microbial life in rocks examined by NASA's Perseverance rover.

With the help of the public, scientists mapped microbial life across 90% of U.S. watersheds by analyzing genetic data from approximately 100 rivers, creating the first comprehensive catalog of U.S.

Each day, coral reefs quietly reshape the microscopic world drifting just above them. As daylight fades and returns, the smallest ocean organisms - bacteria, algae, and single-celled predators - ...
