'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 |

Bird fossil from dinosaur era reveals early avian intelligence origins
London, UK (SPX) Nov 14, 2024 A unique fossil bird discovery is reshaping what scientists understand about the evolution of modern avian brains and intelligence - a topic that has puzzled researchers for decades. The fossil, named 'Navaornis hestiae', dates back around 80 million years to the Mesozoic Era and is remarkably well-preserved, especially its skull. This discovery bridges an evolutionary gap of 70 million years between 'Archaeopteryx', the oldest known bird-like dinosaur from 150 million years ago, and modern birds. ... read more
