Identification of soils that inhibit a tiny soybean-destroying organism is an important tool in reducing yield losses, according to a Purdue University plant pathologist.
Soybean cyst nematodes cause between $800 million and $1 billion annually in crop losses in the United States, according the American Phytopathological Society. However, techniques are available to find soils that specifically suppress these microscopic roundworms, said Andreas Westphal, assistant professor of plant pathology. The female nematodes are white, lemon-shaped parasites that become dead brown shells filled with maturing eggs. Some soils have as yet not-understood characteristics that don’t foster development of the pests.
Westphal, whose research focuses on soybean cyst nematodes and ways to thwart them, said that using nematode-suppressive soils is an easily implemented, environmentally friendly weapon in fighting the parasites, which are found worldwide in soybean-producing areas.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
