| Posted: 30 Oct 2014 11:22 AM PDT As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world's energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation. In many popular applications -- video rendering, for instance -- users probably wouldn't notice the difference, and it could significantly improve energy efficiency. |
| Planet discovered that won't stick to a schedule Posted: 30 Oct 2014 10:33 AM PDT For their latest discovery, astronomers have found a low-mass, low-density planet with a punctuality problem. The new planet, called PH3c, is located 2,300 light years from Earth and has an atmosphere loaded with hydrogen and helium. Its inconsistency kept it from being picked up by automated computer algorithms that search stellar light curves and identify regular dips caused by objects passing in front of stars. |
| Adapative 'nowcasting' key to accurate flu data trends using Google search terms Posted: 30 Oct 2014 08:48 AM PDT Google search data really can provide a more accurate real time picture of current flu infections, researchers have found. Official reports of influenza infection rates are produced with a delay of at least one week. Yet researchers from Google and the Centers for Disease Control and Prevention (CDC) reported that data on searches for influenza related terms could be used to provide a real time estimate of the number of people with flu infections, with almost no delay. |
| Device developed for running shoes that prevents injuries Posted: 30 Oct 2014 08:48 AM PDT A prototype running shoe has been designed with an integrated device that improves training management and prevents injuries. The device consists of a microelectronic measuring system capable of gathering biomechanical parameters that characterize the runner's technique during a race. This information is wirelessly transmitted to the runner's mobile phone and a mobile phone application provides real-time feedback, including level of performance and suggestions to change the running pattern or to stop running in case of detecting a high risk of injury. |
| 'Nanomotor lithography' answers call for affordable, simpler device manufacturing Posted: 30 Oct 2014 07:16 AM PDT What does it take to fabricate electronic and medical devices tinier than a fraction of a human hair? Nanoengineers recently invented a new method of lithography in which nanoscale robots swim over the surface of light-sensitive material to create complex surface patterns that form the sensors and electronics components on nanoscale devices. |
