China's new weapon: Remote-controlled spy bees

Scientists in China have announced that they have implanted control devices into the brains of bees. The device, which weighs less than a pinch of salt, is placed on the back of a worker bee and connected to the insect's brain via tiny needles.

The researchers said the device was successful in nine out of 10 tests, with the bees obeying instructions to turn left or right.
