For years people have believed that excessive cell phone use could be harmful to your health. Now a recent study shows that radiation from your cell phone could actually help protect you from Alzheimer's Disease.
Some things are neither all good or all bad. Actually, that's true about just about everything.
They aren't trying to tell you this type of radiation is good or bad, they are telling you specifically it was effective in blocking amyloid plague dementia.
By the way, the tumors that are about 3.5x more common with cell phone use is the non-cancerous type. Tumor and cancer are not synonyms. Not that any tumor is a good thing, of course.
Beyond the cell phone issue, this does give further insight into Alzheimer's Disease. It doesn't give a lot answers, but it does give a pointer to which questions need to be asked. And if you don't ask the right questions, you aren't going to useful answers.
AHHH, but did they have a control group of mice? And were the researchers blinded? Perhaps the extra attention given to them and the fact that they were living together in a novel environment was enough to promote mental/cognitive stimulation, to enhance memory. Comparable to how mice who have an exercise wheel have higher new neuronal growth rates perhaps.
