‘Microlightning’ in water droplets may have sparked life on Earth
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.
