While city dwellers may be used to railway crossings marked with flashing red lights, the easier-to-miss warnings at rural crossings often just consist of a sign. That's because there's no easy way of providing electricity to such isolated locations. While solar panels could provide part of the solution, a team of engineering students and faculty at the University of Nebraska-Lincoln believe that photovoltaics alone can't consistently provide enough power. Instead, they devised several systems that harness power from the rails themselves.

Amplifying light a few hundred times with magnifying lenses is easy. Amplifying light by altering the resonant properties of light itself is a much more difficult proposition. However, if recent research by engineers at the University of Wisconsin-Madison engineers is anything to go by, the effort is well worth it: They claim to have constructed a nanoscale device that can emit light as powerfully as an object more than 10,000 times its size.

Firefly enzyme inspires Swiss team to create portable disease test kit

By - July 28, 2015 1 Picture

Portable test kits represent an advance in disease diagnosis, as their ready availability increases chances of earlier detection and treatment. This type of technology is constantly evolving, and sometimes inspiration can come from surprising sources. Such is the case with research carried out by a Swiss team, which has borrowed from the mechanics behind the firefly's glow to develop a sensitive molecule detector.
