Washington, DC, 14 April 2015— The cores of terrestrial planets and satellite bodies, including our own Moon, all contain large quantities of iron.
Washington, DC— A Carnegie-led team was able to discover five new forms of silica under extreme pressures at room temperature. Their findings are published by Nature Communications.
Only a small fraction of our planet’s total carbon is found at the surface.
Carbon exists in a variety of structural motifs as a result of its ability to adopt sp-, sp2-, and sp3-type bonding modes.
Washington, DC, 5 February 2015— A team of Geophysical Laboratory scientists have found “beautifully preserved” 15 million-year-old thin protein sheets in fossil shells from southern Maryland.
Washington, DC, December 16, 2014—New work from Carnegie's Ivan Naumov and Russell Hemley delves into the chemistry underlying some surprising recent observations about hydrogen, and reveals remarkable parallels between hydrogen and graphene under extreme pressures.
Washington, DC—Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices—carbon is to biology as silicon is to technology.
Washington, DC —A key to understanding Earth’s evolution is to look deep into the lower mantle—a region some 400 to 1,800 miles (660 to 2,900 kilometers) below the surface, just above the core.
Washington, DC, 27 October 2014—Compared to its nearest planetary neighbors, Venus and Mars, Earth’s atmosphere is unusually enriched in nitrogen relative to primordial noble gases.
Washington, DC— Hydrogen—the most abundant element in the cosmos—responds to extremes of pressure and temperature differently. Under ambient conditions hydrogen is a gaseous two-atom molecule.
