Farmers growing corn in the mid-Atlantic region will have a new tool to help them identify appropriate cultural practices for the types of soils in their fields, thanks to research conducted by researchers from Virginia Tech and Colorado State University.
"Soils vary in their ability to hold water," said Mark Alley, professor of crop and soil environmental sciences at Virginia Tech. "If a farmer knows the water-use efficiency of the soils in his field, he has a very important clue on how to manage that field."
Alley developed a formula for accurately determining the water-use efficiency in typical soils in the region. The results of his research were published in the May-June edition of Agronomy Journal. Co-authors of the article are Jon Roygard, a Virginia Tech research associate, and Raj Khosla, assistant professor of soil and crop science at Colorado State University.
Water is the main limiting factor for non-irrigated corn production in the region. The article examines the relationship between no-till corn yields and soil water availability for the purpose of improving water-use efficiency.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
