Field guide for confirming new earth-like planets described
WUSTL researchers provide a field guide to exoplanets.Astronomers looking for earth-like planets in other solar systems — exoplanets — now have a new field guide thanks to earth and planetary scientists at Washington University in St. Louis. Bruce Fegley, Ph.D., Washington University professor of earth and planetary sciences in Arts & Sciences, and Laura Schaefer, laboratory assistant, have used thermochemical equilibrium calculations to model the chemistry of silicate vapor and steam-rich atmospheres formed when earth-like planets are undergoing accretion. During the accretion process, with surface temperatures of several thousands degrees Kelvin (K), a magma ocean forms and vaporizes.
Calculations favor reducing atmosphere for early earth
David Kilper/WUSTL PhotoFegley and Schaefer examine a meteorite.Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth’s atmosphere was a reducing one, chock full of methane, ammonia, hydrogen and water vapor. In making this discovery Bruce Fegley, Ph.D., Washington University professor of earth and planetary sciences in Arts & Sciences, and Laura Schaefer, laboratory assistant, reinvigorate one of the most famous and controversial theories on the origins of life, the 1953 Miller-Urey experiment, which yielded organic compounds necessary to evolve organisms.

War on intellectual property theft in China best fought at local level, suggests new book
Spurred by concerns over China’s booming economy, the Bush administation plans to crank-up pressure on Chinese authorities to curtail the rampant theft of intellectual property — the black market in pirated films, software and equipment that costs American companies billions in lost sales. While anti-piracy rhetoric plays well in Washington, a new book on the “Politics of Piracy” in China suggests that external diplomatic pressure will have little effect on China’s ability to enforce international norms on copyrights, trademarks and patents. “The key to gaining enforcement of those laws lies at the local level,” says the book’s author, WUSTL China specialist Andrew Mertha.
