1. The Right Painkiller A recent study at the Medical College of Wisconsin tested ibuprofen (Motrin, Advil, etc.) against acetaminophen (Tylenol) plus codeine. Surprisingly, the non narcotic pain reliever rated better when given to children who had broken an arm. The kids ate better, were more active and suffered fewer side effects.

 2. Radiation and Diabetes Kids who've been treated for cancer can have a much higher risk of developing type 2 diabetes as adults. In a study at Memorial Sloan-Kettering Cancer Center in New York, acute myeloid leukemia survivors who were treated with total body radiation were nearly 24 times as likely to become type 2 diabetics as their siblings; survivors who did not have total body radiation had three times the risk. Survivors of other cancers who were treated with radiation to the abdomen were at heightened risk as well. Doctors theorize that the radiation may change how we deposit body fat.

3. Smile, Happy Marriage Ahead Researchers at Indiana's DePauw University compared childhood photographs of 600 adults. Among people who were usually smiling in the photos, the divorce rate was 11 percent; among more serious-faced kids, 31 percent had been divorced. Scientists theorize that an upbeat personality attracts other happy people, giving you a better shot at a successful marriage.

4. The Formula for Feeding We all know breast milk is the healthiest choice, but if you feed your baby formula, you want to give them the best one. Many parents, fearing lactose-intolerance, think cows' milk formula is a poor choice. Yet in a study reported in Nutrition Journal, babies were intolerant of reduced-lactose formula at the same rate – 13percent -- as formula based on cows' milk. Talk to your pediatrician about the best choice for your baby.
