Weizmann Institute researchers find clue to brain damage from cellphones

Dr. Joseph Friedman and colleagues at the Weizmann Institute in Rechovot, Israel, have found that exposing rat and human cell cultures to low-level electromagnetic radiation at frequencies similar to cellphones caused, even after as little as 10 minutes, activation of an enzyme that regulates cell differentiation and division.
Since we started using cellphones, I’ve wondered if they are in fact harmless or maybe less than harmless to our health. There have been other theories around their possible negative effect on our brain cells, including that mobile phones cause the brain to overheat. But manufacturers are careful to ensure their phones don’t overheat users’ brains. And the frequencies are too low to damage DNA directly.
So maybe this is a key in understanding the real health implications of cellphone use. I know so many people who use their cells a lot - for some it is their only phone. Because of this it is so important that research of this kind continues.
And meanwhile, most newer cellphones have a speaker. It might be a good idea to use that whenever possible.
