For the first time, researchers at North Carolina State University have demonstrated that microscopic "two-faced" spheres whose halves are physically or chemically different - so-called Janus particles - will move like stealthy submarines when an alternating electrical field is applied to liquid surrounding the particles.A paper describing the research, published in the Feb.

In an effort to make typing on the iPhone more familiar, the University of Glasgow has unveiled a hack that provides vibration feedback when a virtual key is pressed, simulating the effect of typing on a real keyboard. The patch enables what the University calls haptic feedback, which researchers say can help improve typing speeds, while simultane
