Ancient Earth Crust Stored in Deep Mantle
April 24, 2013 — Scientists have long believed that lava erupted from certain oceanic volcanoes contains materials from the early Earth's crust. But decisive evidence for this phenomenon has proven elusive. New ... > full storyMore: -
Sunlit Snow Triggers Atmospheric Cleaning, Ozone Depletion in the Arctic
April 24, 2013 — Researchers have discovered that sunlit snow is the major source of atmospheric bromine in the Arctic, the key to unique chemical reactions that purge pollutants and destroy ... > full story -
Biological Activity Alters the Ability of Sea Spray to Seed Clouds
April 22, 2013 — Ocean biology alters the chemical composition of sea spray in ways that influence their ability to form clouds over the ocean. That's the conclusion of a team of scientists using a new approach to ... > full story -
Geochemical Method Finds Links Between Terrestrial Climate and Atmospheric Carbon Dioxide
April 22, 2013 — Scientists used a new chemical technique to measure the change in terrestrial temperature associated with a major shift in global atmospheric CO2 concentrations nearly 34 million years ago. Their ... > full story -
NASA's Wind Mission Encounters 'SLAMS' Waves
April 16, 2013 — To tease out what happens at that boundary of the magnetosphere and to better understand how radiation and energy from the sun can cross it and move closer to Earth, NASA launches spacecraft into ... > full story -
The Fukushima Dai-Ichi Nuclear Power Plant Accident: Two Years On, the Fallout Continues
April 15, 2013 — More than two years after the earthquake and tsunami that devastated parts of Japan, scientists are still trying to quantify the extent of the ... > full story -
Reaction Rates of Second Key Atmospheric Component Measured
April 11, 2013 — Researchers have successfully measured reaction rates of a second Criegee intermediate, CH3CHOO, and proven that the reactivity of the atmospheric chemical depends strongly on which way the molecule ... > full storyMore: -
