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.

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.

Geochemistry, High Pressure

Washington, DC, 28 March 2012- A Carnegie scientists' observations have led the way to stabilizing tungsten hydrides under high pressure.

Geochemistry

Washington, DC, 15 September 2011- New research provides direct evidence that the carbon from the Earth's surface can cycle deep into the mantle and then brought back.

Geochemistry

Washington, DC— Scientists have long debated about the origin of carbon in Earth’s oldest sedimentary rocks and how it might signal the remnants of the earliest forms of life on the planet.

Geochemistry, Planetary Science

Washington, DC—Formaldehyde, a poison and a common molecule throughout the universe, is likely the source of the solar system’s organic carbon solids—abundant in both comets and asteroids.

Astrobiology, Geochemistry

Washington, DC— In the 1950s, biochemist Stanley Miller performed a series of experiments to demonstrate that organic compounds could be created under conditions mimicking the primordial Earth.

Geochemistry

Washington, DC—Surprising new research shows that, contrary to conventional belief, remains of chitin-protein complex—structural materials containing protein and polysaccharide—are present in abundance in fossils of arthropods from the Paleozoic era.

Geochemistry

Washington, DC, 1 January 2011-This is an image of organic carbon in a ordinary chondritic meteorite obtained using a scanning transmission X-ray microscope at the Advanced Light Source, Lawrence Berkeley Laboratory.
