In science news, more theories are emerging on what is causing the disappearances of bees across the country and in Europe. As much as 70 percent of the commercial bee population on the East Coast have gone missing. The Independent newspaper of London reports that some scientists believe that cellphones might be causing the problem. The theory is that radiation from mobile phones interferes with bees’ navigation systems, preventing the famously home-loving species from finding their way back to their hives. A limited study at Landau University has found that bees refuse to return to their hives when mobile phones are placed nearby. The disappearance of the bees could cause massive food shortages, because most of the world’s crops depend on pollination by bees. Albert Einstein once said that if the bees disappeared, “man would have only four years of life left.”
