| Engineers unlock potential for faster computing Posted: 22 Sep 2014 12:28 PM PDT Engineers discovered a way to create a special material -- a metal layer on top of a silicon semiconductor -- that could lead to cost-effective, superfast computers that perform lightning-fast calculations but don't overheat. This new "topological insulator" behaves like an insulator on the inside but conducts electricity on the outside.  |
| Posted: 22 Sep 2014 10:07 AM PDT Electrical engineering researchers have developed a unique nanoscale device that for the first time demonstrates mechanical transportation of light. The discovery could have major implications for creating faster and more efficient optical devices for computation and communication.  |
| New bracelet strengthens computer security Posted: 22 Sep 2014 08:30 AM PDT In a big step for securing critical information systems, such as medical records in clinical settings, researchers have created a new approach to computer security that authenticates users continuously while they are using a terminal and automatically logs them out when they leave or when someone else steps in to use their terminal.  |
| Making light work of the workload for overworked healthcare workers Posted: 22 Sep 2014 06:10 AM PDT Modern hospitals are staffed by overworked and overstressed healthcare workers, according to a research paper. As such, new technology must be implemented to reduce the number of treatment errors that arise because of this. With appropriate and regular training, a new article suggests that the advantages and benefits of IT solutions in hospitals such as the use of RFID (radio frequency identification) tags and healthcare management and dispensing software and electronic health records (EHR) can be made clear.  |
