A new long-term animal study of cell-phone radiation suggests that emissions don't cause cancer. However, studies by a second team hint that cell phones may damage people in other ways.
As cellular phones' popularity has soared, so have concerns about health effects from an electromagnetic-radiation source held so near the brain. Although the small amount of energy from a cell phone has been reported to generate stress responses in animals' cells and affect people's reflexes, scientists are still at a loss to say whether such radiation poses significant health risks (SN: 2/12/00, p. 100: Researchers Probe Cell-Phone Effects; 5/20/00, p. 326).
