Fossil discoveries in southern Africa reveal life before catastrophic Permian extinction
Seattle WA (SPX) Aug 13, 2025 An international research team has spent more than 15 years unearthing fossils across southern Africa to better understand life in the Permian period, which began 299 million years ago and ended 252 million years ago in Earth's most severe mass extinction. Led by scientists from the University of Washington and the Field Museum of Natural History, the project identifies species that thrived in southern Pangea before the "Great Dying" eliminated about 70% of land species and an even greater proportion of ... read more |

'Microlightning' in water droplets may have sparked life on Earth
Stanford CA (SPX) Mar 17, 2025 Life may not have begun with a dramatic lightning strike into the ocean but from many smaller "microlightning" exchanges among water droplets from crashing waterfalls or breaking waves. New research from Stanford University shows that water sprayed into a mixture of gases thought to be present in Earth's early atmosphere can lead to the formation of organic molecules with carbon-nitrogen bonds, including uracil, one of the components of DNA and RNA. The study, published in the journal Scienc ... read more
