| Scientists create circuit board modeled on the human brain Posted: 28 Apr 2014 10:40 AM PDT Scientists have developed faster, more energy-efficient microchips based on the human brain -- 9,000 times faster and using significantly less power than a typical PC. This offers greater possibilities for advances in robotics and a new way of understanding the brain. For instance, a chip as fast and efficient as the human brain could drive prosthetic limbs with the speed and complexity of our own actions.  |
| System detects global trends in social networks two months in advance Posted: 28 Apr 2014 06:42 AM PDT A new method of monitoring identifies what information will be relevant on social networks up to two months in advance. This may help predict social movements, consumer reactions or possible outbreaks of epidemics, according to a study. The system works using just 50,000 Twitter accounts, predicting what will "go viral" across the entire Internet. It can be used in real time, about different topics, in different languages and geographical areas, thus allowing for different contexts to be covered.  |
| Green clouds on the horizon for computing Posted: 28 Apr 2014 04:46 AM PDT Small businesses could save up to 62% of energy costs by switching to a cloud computing system for their invoicing, according to research. The approach of integrating cloud computing and a more environmentally-aware approach to information technology also cuts carbon emissions, the team reports, and could work with many other services.  |
| More speed, less interference: Computing, improving electromagnetic interference Posted: 27 Apr 2014 04:07 PM PDT As electronic components on electronic circuit boards continue to shrink, problems of electromagnetic compatibility are arising. Such problems include unwanted 'noise' effects due to electromagnetic interference and susceptibility. "Electromagnetic interference is a critical problem for the electronics industry," explains one researcher. A semi-analytical model recently developed can compute electromagnetic interference on an electronic circuit board ten times faster than existing commercial software, new research shows.  |
| Improving optical communications with new device Posted: 27 Apr 2014 04:07 PM PDT Computer modeling is assisting the design of optical modulators with low losses to improve optical communications. "Our device has a speed and optical losses comparable to existing technology such as lithium niobate," says Lim. "One reason for this high performance is because we used highly accurate computer codes developed in-house," explains one researcher.  |
