National Academies advisory: Critical minerals and national defense stockpile
October 03, 2007The United States uses more than 7.5 trillion pounds of nonfuel minerals each year to produce everyday items such as mobile phones and cars. Two new reports from the National Research Council examine minerals that are critical to the U.S. economy, as well as the effectiveness of the National Defense Stockpile (NDS).
MANAGING MATERIALS FOR A 21ST CENTURY MILITARY examines the continuing need for and value of the NDS, a cache of minerals and other strategic materials considered critical for national defense. The report also addresses how both national security threats and global production of key materials have changed over the decades, and how these changes impact the NDS.
MINERALS, CRITICAL MINERALS, AND THE U.S. ECONOMY identifies some of the economically essential minerals and assesses the current state of mineral information available to decision makers. The report also evaluates the potential constraints on mineral supplies from geological, economic, technical, political, and other issues.

Sensitive laser instrument could aid search for life on Mars
Minuscule traces of cells can be detected in a mineral likely present on Mars, a new study shows. The results, obtained using a technique developed at the U.S. Department of Energy's Idaho National Laboratory, could help mission scientists choose Martian surface samples with the most promise for yielding signs of life.
