Cooked minerals resemble life A laboratory experiment has given rise to tiny filaments that mimic structures found in ancient rocks identified as microfossils. The findings cast further doubt over whether the oldest known microfossils found in the 3.5-billion-year-old Warrawoona Group in Australia were indeed produced by living organisms, with implications for the search for early life on Earth and elsewhere.   |

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. |
