Ash trees in 22 eastern states of U.S.A. are being decimated by emerald ash borers (EABs), an Asian beetle that arrived in Michigan more than two decades ago. The pest has even spread westwards into Kansas and Colorado. Nothing seemed to be effective against EABs, until decoys designed to mimic female EABs were found in 2012 by a group of researchers to be successful in enticing male EABs for mating. Last year, the same researchers found the decoys could be used to electrocute and kill the seduced males.
In an effort that reaches back to the 19th-century laboratories of Europe, a discovery by chemistry researchers establishes new research possibilities for silicon chemistry and the semiconductor industry. The study gives details on the first time chemists have been able to trap molecular species of silicon oxides.
Using a technique that introduces tiny wrinkles into sheets of graphene, researchers have developed new textured surfaces for culturing cells in the lab that better mimic the complex surroundings in which cells grow in the body.
