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.


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.


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.


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.

Washington, DC— Much of our planet’s mineral wealth was deposited billions of years ago when Earth’s chemical cycles were different from today’s.
