High Pressure

Washington, DC — When materials are stressed, they eventually change shape. Initially these changes are elastic, and reverse when the stress is relieved. When the material’s strength is exceeded, the changes become permanent.

High Pressure, Planetary Science

Washington, DC— The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors.

Geochemistry, High Pressure, Materials

Washington, DC, 26 November 2012 -- The Geophysical Laboratory’s Stewart McWilliams and his team find evidence that alters our understanding of planetary evolution.

Materials

Washington, DC--Researchers at the Carnegie Institution have discovered a new efficient way to pump heat using crystals.

High Pressure, Materials

Washington, DC—Carnegie scientists are the first to discover the conditions under which nickel oxide can turn into an electricity-conducting metal.

High Pressure, Materials

Washington, DC — A team of scientists led by Carnegie’s Lin Wang has observed a new form of very hard carbon clusters, which are unusual in their mix of crystalline and disordered structure. The material is capable of indenting diamond.

Geochemistry

Washington, DC — In order to understand Earth's earliest history--its formation from Solar System material into the present-day layering of metal core and mantle, and crust--scientists look to meteorites.

Planetary Science

Washington, DC, 12 July 2012 — New research led by Carnegie scientists indicates that frozen water distributed throughout much of the early Solar System is the source of water on Earth. 

Mineralogy, Planetary Science

Washington, DC — Mineral evolution posits that Earth’s near-surface mineral diversity gradually increased through an array of chemical and biological processes.

Astrobiology, Planetary Science

Washington, DC — Molecules containing large chains of carbon and hydrogen--the building blocks of all life on Earth--have been the targets of missions to Mars from Viking to the present day.
