Clues to climate cycles dug from south pole snow pit
Particles from the upper atmosphere trapped in a deep pile of Antarctic snow hold clear chemical traces of global meteorological events, a team from the University of California, San Diego and a colleague from France have found. Anomalies in oxygen found in sulfate particles coincide with several episodes of the world-wide disruption of weather known as El Nino and can be distinguished from similar signals left by the eruption of huge volcanoes, the team reports.

Study: Ice forms a perfect crystal, becomes ferroelectric
Chemists at Ohio State and elsewhere may have settled a 70-year-old scientific debate on the fundamental nature of ice.
