RougeFemme writes "As part of a research project to develop low-cost artificial hands, DARPA has developed a two-hand robot that can almost change a tire. Research has mastered grasping objects with robotic hands; the next objective is to manipulate the objects once grasped. Research also continues on a neural interface, a direct link between a robotic arm and the human brain. The ultimate goal of the research project is to develop prostethics and robotic arms for wider use, by reducing cost and improving dexterity and machine vision."
New submitter alysion writes "Per research published in the online journal PLOS One, psychologists Christine Ma-Kellams of Harvard University and Jim Blascovich of the University of California, Santa Barbara report, 'Thinking about science leads individuals to endorse more stringent moral norms.' In one of the four supporting experiments, undergraduates considered an account of a date rape and were asked to judge behavior on a scale of 1 to 100. Science types, perhaps not surprisingly, proved to have a better grasp of reality, including the moral kind."
First time accepted submitter CanadianRealist writes "Electrolysis of water to produce hydrogen is very inefficient without the use of a catalyst. Unfortunately catalysts are currently made of crystals containing rare, expensive toxic metals such as ruthenium and iridium. Two chemists from the University of Calgary have invented a process to make a catalyst using relatively non-toxic metal compounds such as iron oxide, for 1/1000 the cost of currently used catalysts. It is suggested this would make it more feasible to use electrolysis of water to create hydrogen as a method of storing energy from variable green power sources such as wind and solar."
