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.

Geochemistry, High Pressure

Argonne, ILL—For the first time scientists have been able to watch nanoparticles grow from the earliest stages of their formation. Nanoparticles are the foundation of nanotechnology and their performance depends on their structure, composition, and size.

Geochemistry

Washington, DC—An unprecedented study of bald eagle diet, from about 20,000 to 30,000 years ago to the present, will provide wildlife managers with unique information for reintroducing Bald Eagles to the Channel Islands off California.
