Study sheds light on aluminum reaction in low pH environments

Within the deep strata of the San Telmo "acid pit lake" in southwestern Spain rests a wealth of rich geochemical knowledge. That knowledge recently helped researchers at Penn State discover new information about the chemical ...

Intensity of desert storms may affect ocean phytoplankton

Each spring, powerful dust storms in the deserts of Mongolia and northern China send thick clouds of particles into the atmosphere. Eastward winds sweep these particles as far as the Pacific, where dust ultimately settles ...

Comet Wild 2: A window into the birth of the solar system?

Our solar system, and other planetary systems, started as a disk of microscopic dust, gas, and ice around the young Sun. The amazing diversity of objects in the solar system today - the planets, moons, asteroids, and comets ...

Encouraging minerals to capture troubling radionuclides

Associated with contamination in certain spots around the world, pentavalent neptunium does not always behave the same as its stand-in when moving through the soil, according to scientists at University of Notre Dame and ...

Geochemical process on Saturn's moon linked to life's origin

New work from a team including Carnegie's Christopher Glein has revealed the pH of water spewing from a geyser-like plume on Saturn's moon Enceladus. Their findings are an important step toward determining whether life could ...
