Troy, N.Y. – Geochemists at Rensselaer Polytechnic Institute are challenging commonly held ideas about how gases are expelled from the Earth. Their theory, which is described in the Sept. 20 issue of ...

Researchers have discovered argon trapped in air-hydrate crystals in ice cores, which can be used to reconstruct past temperature changes and climate shifts. On the massive sheets of ice that stretch ...

Solar wind has slowly torn away Mars’ atmosphere over time, helping to transform a planet that was once warm and wet into the cold, dry, inhospitable one we see today. Chemical sleuths explain in a ...

Geochemists are challenging commonly held ideas about how gases are expelled from the Earth. Their theory could change the way scientists view the formation of Earth's atmosphere and those of our ...
