Cellphones are dangerous / not dangerous: handsets alter brain activity -- scientists don't know what that means
Cellphones are bad, mmkay? Or at least that is what many want us to believe, what with all these warning labels and studies telling us that mobile users will end up with brain cancer and kidney damage. Not to mention the dangers of phone addiction -- horror of horrors -- for our youth. Now, the National Institutes of Health have shown that radiation from your phone's antenna turns you into a supergenius increases brain activity. Using positron emission tomography (PET) scans on 47 individuals with a muted phone on each ear (to prevent aural brain stimulation), the study found a seven percent increase in brain activity in the area closest to the phones' antennas when receiving a call. The catch -- scientists don't know "whether this is detrimental or if it could even be beneficial," so don't go trading your Cell-Mate in for a Bluetooth headset just yet.
Study finds cellphone use may fend off effects of Alzheimer's disease
Could cellphone radiation actually be good for you and bad for you at the same time? It might, according to a group of researchers at the University of South Florida, who say that tests on mice suggest that long-term cellphone use might actually help fend off some of the effects of Alzheimer's disease. That, as you might have suspected, is the exact opposite of what the researchers expected to find, and they say that exposure to electromagnetic waves from cellphones could both prevent some of the effects of Alzheimer's if the exposure is introduced in early adulthood, or potentially even reverse some of the impairment among those already memory-impaired. Needless to say, the tests are still in the earliest of stages, but the researchers are apparently planning on modifying the experiment to try to speed up the results, and eventually expand it to include tests on humans. Tests on mice still found cellphones to be an impairement while driving. [Thanks, Antonio]
