Researchers identify driver for near-Earth space weather
12-11-2006 · EurekAlert!New findings indicate that the aurora and other near-Earth space weather are driven by the rate at which the Earth's and sun's magnetic fields connect, or merge, and not by the solar wind's electric field as was previously assumed.

- Space Weather Gear Readied For The Final Frontier
09-29-2006 · ScienceDaily
Atmospheric outflows, auroral emissions and plasma winds? While those aren't terms we hear on the average weather forecast, they cause cosmic storms that rage just outside the Earth's atmosphere and often wreak havoc with telecommunications networks, power grids and other technology essential to Canadian society. Researchers are hoping to gain a better understanding of this "space weather" with a suite of scientific instruments being developed under the leadership of the University of Calgary's Institute for Space Research.

- Soil nutrients shape tropical forests, large-scale study indicates
01-11-2007 · EurekAlert!
Tropical forests are among the most diverse plant communities on earth, and scientists have labored for decades to identify the ecological and evolutionary processes that created and maintain them. A key question is whether all tree species are equivalent in their use of resources -- water, light and nutrients -- or whether each species has its own niche.A large-scale study by researchers at the University of Illinois at Urbana-Champaign and eight other institutions sheds some light on the issue.

- Arizona State University scientist finds Martian ice is patchy and variable
05-02-2007 · EurekAlert!
For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.
