Mineralogy

Bob Hazen, staff scientsist at the Geophysical Laboratory, continues our Neighborhood Lecture Series with the second of four lectures. The distribution of minerals on Earth, Mars, and other worlds mimics social networks, as commonly applied to such varied topics as Facebook interactions, the spread of disease, and terrorism networks.

Geochemistry, High Pressure

Washington, DC—New work from a research team led by the Geophysical Laboratory's Anat Shahar contains some unexpected findings about iron chemistry under high-pressure conditions, such as those likely found in the Earth’s core, where iron predominates and creates our planet’s life-shielding magnetic field.

The Geophysical Laboratory’s own Bob Hazen will be starring in “Life’s a Rocky Start,” a PBS NOVA special on January 13, 2016 at 9pm EST on PBS. 

Mineralogy

The Geophysical Laboratory's Anat Shahar and Bob Hazen were announced as the recipients of the Mineralogical Society of America's (MSA) 2016 MSA Award and Roebling Medal, respectively.  They will receive their awards at the MSA meeting in Denver in September 2016.

Geochemistry

If you freeze a liquid fast enough, it becomes a glass, something that is structurally similar to liquid but incapable of flow. This concept holds true even for metals.

Mineralogy

Washington, DC—New research from a team led by Carnegie’s Robert Hazen predicts that Earth has more than 1,500 undiscovered minerals and that the exact mineral diversity of our planet is unique and could not be duplicated anywhere in the cosmos.

Geochemistry, Planetary Science

Washington, DC— 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.

Geochemistry

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.

Geochemistry

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.
