"... Stanford researchers report Aug. 26 in Proceedings of the National Academy of Sciences, is that microscopic droplets of water spontaneously produce hydrogen peroxide."
"The team eventually traced those results to the presence of a molecule called hydroxyl—a single hydrogen atom paired with an oxygen atom -- that can also act as a reducing agent. That equally unexpected result led Katherine Walker, at the time a graduate student in Zare's lab, to wonder whether hyrogen peroxide -- a molecule with two hydrogen and two oxygen atoms—was also present."
