Asteroid tells secrets of Earth's 'far wetter' building blocks
Tokyo (AFP) Sept 10, 2025 Earth's building blocks were "far wetter" than previously imagined, new analysis of tiny samples from a distant asteroid has suggested, overturning long-held assumptions about the early solar system. Research on a tiny portion of the 5.4 grams of rock and dust collected from the Ryugu asteroid, some 300 million kilometres (185 million miles) from Earth, offers new insights into how the solar system looked in the early life of our planet. Scientists believe the reason Earth has oceans, lakes and ... read more |

How survivors spanned the globe after Earth's biggest mass extinction
Stanford CA (SPX) Mar 30, 2025 Scientists don't call it the "Great Dying" for nothing. About 252 million years ago, upward of 80% of all marine species vanished during the end-Permian mass extinction - the most extreme event of its kind in Earth's history. What followed was a mysterious, multimillion-year span that could be called the "Great Dulling," when marine animal communities looked remarkably alike all over the planet, from the equator to the poles. Researchers have long sought an explanat ... read more
