President Bush’s call this week for Congress to end its decades-old ban on offshore oil and gas drilling has highlighted key differences in the big-oil platforms of presumptive Republican and Democratic presidential nominees Barak Obama and John McCain, suggests William Lowry, an expert on the politics of environmental and energy issues at Washington University in St. Louis.

What’s beyond the solar system? Astronomers say there are planets similar to ours “out there”.The world is abuzz with the discovery of an extrasolar, Earth-like planet around the star Gliese 581 that is relatively close to our Earth at 20 light years away in the constellation Libra. Bruce Fegley, Jr., Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, has worked on computer models that can provide hints to what comprises the atmosphere of such planets and better-known celestial bodies in our own solar system. New computer models, from both Earth-based spectroscopy and space mission data, are providing space scientists compelling evidence for a better understanding of planetary atmospheric chemistry.

Steven SmithPresident George W. Bush’s State of the Union address on Jan. 23 may be remembered as one of the least consequential State of the Union addresses in a generation, but its presentation could open the door on a period of real legislative compromise as both parties struggle to boster reputations in advance of the 2008 elections, suggests Steven Smith, an expert on congressional politics at Washington University in St. Louis.

Storing hydrogen is problematic. A WUSTL chemist and his colleagues are exploring different approaches to help make hydrogen fuel more practical.A chemist at Washington University in St. Louis hopes to find the right stuff to put the element hydrogen in a sticky situation. Lev Gelb is exploring several different ways to store hydrogen and prepares theoretical models of molecules that could enable storage and transport of hydrogen gas. One process would involve materials that hydrogen would stick to.

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.
