In Vadose Zone Journal, researchers state that a much smaller spatial resolution should be used for modeling soil water.

Soils are complicated porous media that are highly relevant for the sustainable use of water resources. Not only the essential basis for agriculture, soils also act as a filter for clean drinking water, and, depending on soil properties, they dampen or intensify surface runoff and thus susceptibility to floods. Moreover, the interaction of soil water with the atmosphere and the related energy flux is an important part of modern weather and climate models.

An accurate modeling of soil water dynamics thus has been an important research challenge for decades, but the prediction of water movement, especially at large spatial scales, is complicated by the heterogeneity of soils and the sometimes complicated topography.

The Hercules Beetle is remarkable not only for its strength, able to carry up to 850 times its own weight, but also the protective outgrowth of its exoskeleton, which also changes from green to black as its surrounding atmosphere gets more humid.

It's the strongest creature in the world but the color-changing trick is what scientists have long sought to understand. A new investigation into the structure of this peculiar protective shell which could aid design of ‘intelligent materials.’

Wind energy is regarded by many as the most viable source of short-term renewable energy.

Optimal operation of new generation wind turbines will only be possible through the reliable measurement of the wind inflow characteristics. Experience has shown that accurate power generation estimation based on wind speed is a challenging task.

For large new turbine models, conventional mast wind speed measurements are not feasible based on cost and technical considerations. Researchers at the Endowed Chair of Wind Energy (SWE) of the University of Stuttgart are working together with researchers from the University of Oldenburg and other project partners on an alternative remote sensing technique.

Radio waves accelerate electrons within Jupiter’s magnetic field in the same way as they do on Earth, according to new research. The discovery overturns a theory that has held sway for more than a generation and has important implications for protecting Earth-orbiting satellites.

Using data collected at Jupiter by the Galileo spacecraft, Dr Richard Horne of British Antarctic Survey (BAS) and colleagues from the University of California, Los Angeles, and the University of Iowa found that a special type of very low frequency radio wave is strong enough to accelerate electrons up to very high energies inside Jupiter’s magnetic field.

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have published new research in Molecular Pharmacology identifying the structure of a receptor in the brain implicated in conditions such as epilepsy and pre-menstrual tension. The same receptor has also been reported to be highly sensitive to alcohol.

The University of Cambridge team, in collaboration with colleagues at Aston University and the University of Alberta, have determined the arrangement of the constituent parts of an uncommon but important type of GABA receptor in the brain. GABAA receptors in the central nervous system play important roles in the body’s response to gamma-aminobutyric acid (GABA), a chemical used by the brain to control certain functions.

By understanding how the receptors’ sub-units are arranged, scientists may now be able to develop drugs to block or stimulate them, providing hope for sufferers of a range of conditions.

Although it's been a half century since America entered the space age, the basic propulsion concepts used to push Explorer I into space will be the same type of propulsion that the nation will use to begin the next half century of space exploration.

It was January 31, 1958 when a Redstone-Jupiter C rocket developed in Huntsville, Ala., lifted the 30-pound artificial satellite into space.

Clark Hawk, director of the Propulsion Research Center at The University of Alabama in Huntsville (UAHuntsville) has seen most of the advances that have taken place in rocket propulsion. He has spent 50 years conducting research in the field.
