Scientists at Rutgers, The State University of New Jersey, have unlocked an important door to understanding one of the most important crops in the world – corn. Researchers at Rutgers Waksman Institute of Microbiology have redefined the nature of heterosis or hybrid vigor, the phenomenon underlying corns remarkable success. Heterosis is the robustness seen in hybrids when different lines are crossed and result in higher yields than either of the parental lines would produce themselves.
Maize (corn) dominates agriculture in the United States, where, according to the National Corn Growers Association, 9 billion bushels are produced annually at a value of more than $21 billion. No crop rivals its total grain yield or the diversity of its uses. Virtually all corn varieties grown today are hybrids. Understanding the genetic basis of heterosis could revolutionize our thinking about genetics and pave the way to even stronger, healthier or more productive strains.
Rentao Song and Joachim Messing of Rutgers Waksman Institute of Microbiology discuss their findings in a paper published in the July 22 issue of the Proceedings of the National Academy of Science. The paper is currently available online.

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...
