Bees are dying at an unprecedented rate through the mysterious colony collapse disorder (CCD), usually attributed to pesticides, disease, and parasites. Harvard University came up with RoboBees to help solve the problem. The tiny, bee-size robots, which weigh less than a tenth of a gram, can lift off the ground and hover if they are tethered to a power supply. The researchers are working to get the robots to "talk" to one another as honeybees do and to transmit pollen. They think it could be functional within 10 to 15 years.
