PHILLIPS: A new study says that cell phone waves can increase your brain's activity, adding new fuel to the back and forth over the safety of your mobile phone. Senior medical correspondent Elizabeth Cohen breaking down the numbers and shows us how the study's author is playing it safe.</s>ELIZABETH COHEN, CNN SENIOR MEDICAL CORRESPONDENT: Studies have gone back and forth on whether holing a cell phone up to your head can cause cancer or other health problems. Well, now there's a new study out to add to the fray. This study found that when people held cell phones up to their head for 50 minutes, that it increased the activities of brain cells. What does that mean exactly? Well, cells do certain activities, such as making glucose normally, but what they found is that the cells were much more active when a cell phone was held up to their head. What does this mean for you and me? Well, the author of the study says, look, the bottom line is we don't know what cell phones do or don't do to your brain. So in the meantime, you can do what she does, use one of these devices, simple, a wire that sticks into your phone and goes in your ears and that keeps the radiation at a distance. That's what the author of study does. Now the cell phone industry says that there are many different studies on this, and that the body of evidence says that cell phones do not cause health problems. Back to you.</s>PHILLIPS: Moammar Gadhafi has been the Libyan leader for 41 years, and I guess we would say he's kind of odd. Jeanne Moos with his most unusual ways next.
