Butterfly to improve solar energy efficiency Posted: 31 Jul 2015 06:52 AM PDT Scientists at Exeter University have been taking a long hard look at the Cabbage White butterfly and believe the way it flies will help to make solar energy cheaper and improve its efficiency. Cabbage White butterflies take a v-shape posture to warm their muscles before they take off, and the Exeter researchers believe that by mimicking this posture, solar panel could deliver nearly 50 percent more power. By creating the wing like shape, the scientists say the power to weight ratio of the solar panel increases by 17 times, making it "vastly" more efficient. Cabbage Whites fly before other butterflies do on cloudy days and that's because they maximise concentrating solar rays onto their thorax, with substructures in the wings let light from the sun to be reflected more efficiently. Richard ffrench-Constant, a professor who specialises in butterfly mimicry at the University of Exeter, said: "The lowly Cabbage White is not just a pest of your cabbages but is actually an insect that is expert at harvesting solar energy."

ARM buys security company Posted: 31 Jul 2015 06:43 AM PDT UK semiconductor design firm ARM said it bought an Israeli based company yesterday to bolster security for designs. Sansa Security provides hardware security and software for system on a chip semiconductors used in the internet of things. Sansa intellectual property is already embedded in over 150 million products and used in smart connected devices and enterprise systems. ARM didn't say how much it paid for Sansa, but Mike Muller, the company's chief technology officer spelled out the reasons it bought the firm. "Any connected device could be a target for a malicious attack so we must embed security at every potential attack point. Protection against hackers works best when it is multi-layered, so we are extending our security technology into hardware susbsystems and trusted software." ARM already has its own embedded TrustZone technology and it claims the acquisition will allow for the protection of connected devices and managing sensitive data.
