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. |

Truth, Fiction and Everything in Between at Yellowstone The Yellowstone caldera is a volcano, and it almost certainly will erupt again someday. It's possible, though unlikely, that future eruptions could reach the magnitude of Yellowstone's three largest explosive eruptions, 2.1 million, 1.3 million and 640,000 years ago. |
