Scientists have developed a new technique that makes pesticides more effective by removing insects ability to exhibit resistance. Their research will extend the effective life of current pesticides, significantly reduce the amount that needs to be sprayed and remove the need for farmers to move to stronger and more harmful chemicals.
Researchers at Rothamsted Research in Hertfordshire, working with researchers in New South Wales, Australia have developed a way to counter the pests most common way of becoming resistant and in trials it has proved to be almost 100 per cent effective.
Resistance to pesticides is a global problem, which is hitting tropical and developing countries particularly hard. Insect pests often develop resistance by over-producing enzymes that degrade the effectiveness of a pesticide. The Rothamsted scientists, supported by the Biotechnology and Biological Sciences Research Council (BBSRC), have developed a product that blocks the enzymes and then delivers a dose of pesticide 4-5 hours later to kill the newly defenceless insect.

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...
