New NSF plane will go higher and farther on environment studies

A new aircraft with exceptional research capabilities is scheduled to arrive at the National Center for Atmospheric Research (NCAR) in Colo., this Friday. Known as HIAPER (High-performance Instrumented Airborne Platform for Environmental Research), the $81.5 million aircraft will serve the environmental research needs of the National Science Foundation, (NSF), NCAR’s primary sponsor and owner of the aircraft, for t

Two centuries ago, it took Lewis and Clark three years to cross half of North America. It’s taking Michigan Technological University’s Russell Alger and his teammates only a little longer to blaze a trail to the South Pole.

Of course, Antarctica poses special challenges. Ninety-eight percent of the continent is buried under thousands of feet of ice. And it doesn’t help that the trail builders can only work for a few weeks during the summer and have to start over again every year f

Students from Duke University’s Pratt School of Engineering are partnering with Carnegie Mellon University’s “Red Team” in an effort to win a $2 million prize from the Defense Advanced Research Projects Agency (DARPA). All they have to do is complete the toughest ground course ever devised for a self-guided robotic vehicle.

The contest, called the DARPA Grand Challenge, is a race between fully self-guided ground vehicles to be conducted in the Southwestern United States on Oct. 8,

The engineers who built the massive external fuel tank that will power the shuttle Discovery into orbit this spring used sophisticated X-ray detectors developed by UF researchers to reduce the chance of a defect in the foam insulation covering the tank. The detectors, first invented as a new technology to find land mines, can identify tiny gaps, or air-filled voids, in the insulating foam without causing any damage. It is believed that such a gap – possibly located between the foam and the ta

Geothermal researchers at Sandia National Laboratories have developed sensors that can be placed in hotter and higher-pressure underground environments than previous instruments, a capability that is allowing geologists worldwide to make more precise measurements of subterranean conditions before and after large earthquakes occur.

The researchers hope the new sensors will provide geologists with a better understanding of earthquake-related phenomena and possibly provide more

Researchers who studied a man-made wetland in Ohio for two years concluded that the created wetland filtered and cleaned water as well as or better than would a natural marsh.

The wetland, which was built in an agricultural area, reduced levels of phosphorus by nearly 60 percent and nitrates by 40 percent. Phosphorus and nitrates are prime ingredients in both fertilizers and in water pollution.

High levels of these nutrients can cause algae to flourish, often to the detr
