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.  |

'Ocean methane paradox' solved? Numerical simulation of methane production by methanogenic microorganisms suggests that up to 400 billion tonnes of methane could be sitting under the ice. If the ice sheet collapses due to a warming climate, this could release the gas, which in turn would increase warming, the researchers say.  |

Microbes Reshuffle Earth's Early History Previously, scientists used microfossil evidence to date the earliest eukaryotes to about 1.8 billion years old, and the earliest cyanobacteria to about 2.1 billion years old. Now, geologists present new evidence suggesting both types of organisms existed as early as 2.45 billion years ago.  |
