Magnetic mirrors enable new technologies by reflecting light in uncanny ways

Posted: 16 Oct 2014 07:03 AM PDT

Scientists have demonstrated, for the first time, a new type of mirror that forgoes a familiar shiny metallic surface and instead reflects infrared light by using an unusual magnetic property of a non-metallic metamaterial. Using nanoscale antennas, researchers are able to capture and harness electromagnetic radiation in ways that have tantalizing potential in new classes of chemical sensors, solar cells, lasers, and other optoelectronic devices.

Simple and versatile way to build 3-D materials of the future

Posted: 16 Oct 2014 05:58 AM PDT

Researchers have developed a novel yet simple technique, called 'diffusion driven layer-by-layer assembly,' to construct graphene into porous three-dimensional structures for applications in devices such as batteries and supercapacitors.

Brain surgery, by robot, through the cheek

Posted: 15 Oct 2014 12:25 PM PDT

Engineers have developed a surgical robot designed to perform brain surgery by entering through the cheek instead of the skull that can operate on a patient in an MRI scanner. Additionally, the engineers have designed the system so that much of it can be made using 3-D printing in order to keep the price low.

Bias in transportation system design exposed

America's streets are designed and evaluated with an inherent bias toward the needs of motor vehicles, ignoring those of bicyclists, pedestrians, and public transit users, according to a new study.
