Paleobiology & Biosignatures: November 2006

Mineral Surfaces and Life

Robert Hazen, from NAI's Carnegie Institution of Washington Team, published his 2005 Presidential Address to the Mineralogical Society of America in this month's American Mineralogist.

Oxygen and Life in the Precambrian

The December 2006 issue of Geobiology is a collection of papers focusing on the history of Earth's biogeochemistry, from the earliest sedimentary rocks in Greenland to the late Proterozoic. The rise of atmospheric oxygen provides a thematic link.

NAI has approved funding for the development of a new, state-of-the-art facility capable of recreating past atmospheric and oceanic conditions, to be called VAL, the Variable Atmospheres Laboratory. Capable of simulating various combinations of oxygen, carbon dioxide, temperature, and hydrogen sulfide levels, this facility will be able to test new hypotheses for the cause of some of the Earth's major mass extinction events - such as the Permian and Triassic mass extinctions.
