2012 budget requests a mixed bag for science

The Obama administration emphasized scientific innovation and education in its fiscal year 2012 budget requests. On Monday, the president’s science advisor, John Holdren, summarized the requests across the different agencies as part of a “tough-love” strategy outlined in the president’s State of the Union speech in January to “win the future.”

Mineral Resource of the Month: Copper

Copper, the “red metal,” was the first metal used by humans more than 10,000 years ago; it was one of the most important materials in the development of civilization. The alloying of copper with tin to form bronze, a harder, stronger and more readily cast metal, gave rise to the Bronze Age. Copper continues to be important today. It is the third-most-used metal in the world, and new uses for it continue to be developed.

Geomedia: Zombie Science? New Madrid and "Disaster Deferred"

During the winter of 1811-1812, three strong earthquakes between magnitude 7 and 8 rocked the New Madrid seismic zone, which runs through parts of eastern Missouri and northeastern Arkansas. The quakes opened deep fissures, destroyed forests and lakes, and produced intense ground shaking that liquefied the soil, turning the land to the consistency of jelly across an area of 10,000 square kilometers.

Mineral Resource of the Month: Molybdenum

Molybdenum is a silvery-white, malleable metal that does not occur in metallic form in nature. Although a number of molybdenum-bearing minerals have been identified, only one has commercial significance: molybdenite, a natural molybdenum sulfide. Molybdenite concentrate is converted to molybdic oxide, which in turn is used to produce intermediate products, such as ferromolybdenum, metal powder and various chemicals.

Mineral Resource of the Month: Clay Minerals

Clays were one of the first mineral commodities used by people. Clay pottery has been found in archeological sites that are 12,000 years old, and clay figurines have been found in sites that are even older. One of the most famous examples is the 2,200-year-old army of terracotta (clay) warriors — 8,000 of them — found in Shaanxi Province, China. Today, the production of clays is among the largest of the world’s minerals industries, exceeding 1 billion metric tons per year. Clays are used in everything from shampoo to kitty litter to pottery to cement.

Mineral Resource of the Month: Silicon

Silicon is classified as a metalloid element because it has properties of both metals and nonmetals. As the second-most abundant element in Earth’s crust — second only to oxygen — it accounts for more than 25 percent of the crust by weight. By mass, silicon is the eighth-most common element in the universe. Yet it is rarely found free in nature. Rather, it occurs chiefly in silicate minerals, such as feldspars, hornblendes, phyllosilicates, the serpentine group of minerals and micas, and in quartz and microcrystalline forms of quartz, such as agate and flint. These minerals are found in many different rocks, including granites and schists. Sand is commonly composed of small particles of quartz.
