In a study at Panjab University in Chandigarh, northern India, researchers fitted cell phones to a hive and powered them up for two fifteen-minute periods each day. After three months, they found the bees stopped producing honey, egg production by the queen bee halved, and the size of the hive dramatically reduced.
The key behind the disturbance, some scientists believe, is a pigment called cryptochrome. Bees and many other insects use cryptochrome to sense the Earth’s magnetic field and use that knowledge to find their ways back to their hives. But some of the radiation emanating from cell phones is disturbing the bees sense of direction. Basically, the bees never get home once they leave.
