Scientists find new principle for spin transistor

July 20, 2012 9:04 am | News | Comments

In conventional field effect transistors, the current through the device can be switched on and off by an electric field. A research team in Poland, however, has developed a new way to control electron current in a transistor-like structure by using the electrons’ spin. The new method can not only tune the electrical current in the device but also the spin-polarization of the electron current.

Frog calls inspire new algorithm for wireless networks

July 17, 2012 7:02 am | News | Comments

Males of the Japanese tree frog have learned not to use their calls at the same time so that the females can distinguish between them. Scientists at the Polytechnic University of Catalonia have used this form of calling behavior to create an algorithm that assigns colors to network nodes—an operation that can be applied to developing efficient wireless networks.
