New cell phones can send messages and take photos. Now for $35, your cell phone can become a lie detector too.

Scientists can?t seem to decide whether cellphones are safeor not. Now Dariusz Leszczynski at the Radiation and NuclearSafety Authority in Finland has found that one hour ofexposure to cellphone radiation caused cultured human cellsto shrink. The blood-brain barrier normally preventsunwanted molecules from entering the brain, but cellphoneradiation targets proteins in the “stress fibers” of thecells that line blood vessels, which causes these cells toshrink. Leszczynski thinks cellphone radiation might allowdangerous molecules to pass through the spaces betweencells, that become enlarged due to the shrinking of the cellitself, and get into the brain that way.
