Study: Cell phones may be killing bees

London, England — A new study has suggested that cell phone radiation may be contributing to declines in bee populations in some areas of the world. Bee populations dropped 17 percent in the UK last year, according to the British Bee Association, and nearly 30 percent in the United States says the U.S. Department of Agriculture.
But researchers in India believe cell phones could also be to blame for some of the losses.
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.
It’s not just the honey that will be lost if populations plummet further. Bees are estimated to pollinate 90 commercial crops worldwide. Their economic value in the UK is estimated to be $290 million per year and around $12 billion in the U.S.
Andrew Goldsworthy, a biologist from the UK’s Imperial College, London, has studied the biological effects of electromagnetic fields. He thinks it’s possible bees could be affected by cell phone radiation.
The reason, Goldsworthy says, could hinge on a pigment in bees called cryptochrome.
“Animals, including insects, use cryptochrome for navigation,” Goldsworthy told CNN.
“They use it to sense the direction of the earth’s magnetic field and their ability to do this is compromised by radiation from [cell] phones and their base stations. So basically bees do not find their way back to the hive.”
Goldsworthy has written to the UK communications regulator OFCOM suggesting a change of phone frequencies would stop the bees being confused. Read more.
