Findings may lead to new methods to control beetles, which have decimated Lake Tahoe and Western forests
University of Nevada, Reno scientists have ended a decade-long controversy over the process by which bark beetles make pheromones: they manufacture their own monoterpenes – the fragrant substances plants produce and which are often used in perfumes. It had been thought that insects and other animals were incapable of making these substances.
"The goal of our research is ultimately to control pheromone production," said Gary Blomquist, professor and chair of biochemistry and molecular biology, who co-authored with several members of his department an article that will be published this week(June 27 – July 1) in the Proceedings of the National Academy of Sciences (PNAS).
Bark beetles plague pine forests, especially when the trees are stressed. The Lake Tahoe basin lost 30 percent of its pines to bark beetle infestation during the 1986-1994 drought, according to Blomquist.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
