She says that her aim is to decode which elements of bird songs enable them to communicate about mating and reproduction, territorial boundaries, age, and even overall health.

"If a soldier wants to find a bomb (with a robot), 95 percent of their attention has to be focused on the screen," Doug Few, an engineer at the Idaho National Laboratory (INL) working on the project, told Discovery News.

London, Dec 20 : In order to overcome problems of speed and range encountered with micro air vehicles, scientists have now developed a vertical-takeoff micro aircraft.

Micro air vehicles (MAVs) are uncrewed aircraft with a wingspan of 15 centimetres (5.9 inches) or less and are commonly used by the military or police forces for surveillance.

Most of the MAVs, just like a full-sized airplane, are controlled by conventional moving aerodynamic surfaces such as flaps.
