Early Life Lines Make Waves Life on Earth just got a little older. New evidence from an ancient rock formation in Australia is bolstering one side of a long-standing debate: that the earliest life on Earth helped shape thousands of finely-layered sediment mounds within the rock. |

Slushball Life Hundreds of millions of years ago, a carapace of ice may have periodically covered the entire planet. New research, however, indicates that microbes seem to have thrived in certain places that they should not have during that time, leading scientists to conclude that the snowball was more slushy than frozen solid. |

Mineral-Making Microbes For the first time, researchers have found direct evidence that microbes can create templates for unique mineral growth. The discovery could inspire new avenues for materials research, as well as for the search for evidence of life on Earth and other planets. |
