  • Sep 27, 2016 Secure passwords can be sent through your body, instead of air Engineers have devised a way to send secure passwords through the human body using smartphone fingerprint sensors and laptop touchpads -- rather than over the air where they're vulnerable to hacking.
  • Sep 27, 2016 Deepwater Horizon oil spill caused widespread marsh erosion, study shows The Deepwater Horizon oil spill six years ago caused widespread marsh erosion that may be permanent in some places, according to a new analysis of 270 miles of the Louisiana, Mississippi and Alabama coasts. At the hardest-hit of 103 Natural Resource Damage Assessment (NRDA) sites, where oil covered more than 90 percent of plants' stems, widespread die-off of grasses at the marsh edge occurred, followed by up to two years of accelerated erosion as dying plant roots lost their grip on marsh soil.
  • Sep 27, 2016 Record for perovskite/CIGS tandem solar module Thin-film technologies can dramatically reduce the cost of next-generation solar modules, say scientists. Whereas their production cost is low, it is in particular the combination of complementary absorber materials in a tandem solar module that increases the power conversion efficiency. Researchers demonstrate that a perovskite/CIGS tandem thin-film solar module that achieves 17.8 percent in efficiency, surpassing for the first time the efficiency of separate perovskite and CIGS solar modules.
  • Sep 27, 2016 First quantum photonic circuit with an electrically driven light source Whether for use in safe data encryption, ultrafast calculation of huge data volumes or so-called quantum simulation of highly complex systems: Optical quantum computers are a source of hope for tomorrow's computer technology. For the first time, scientists now have succeeded in placing a complete quantum optical structure on a chip. This fulfills one condition for the use of photonic circuits in optical quantum computers.
