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.   |

Mystery of jumping crystals solved The riddle of why a certain type of crystal leaps more than 10,000 times its length when exposed to light may have been solved. The crystals' rapid movement is a result of stresses generated in the crystal when light induces a structural change within it. |
