For years, mothers have been divided sharply on the issue of bottle-feeding versus breastfeeding. Studies have long supported the notion that breastfeeding provides infants with benefits like improved immunity to diseases, better maternal bonding and a plethora of important nutrients.

Sure, there have been a few studies backing this idea before, but it’s one of those conclusions that you can never really hear enough: cell phones do not increase your risk of brain cancer.

This isn’t quite a shocker, but scientists are reporting that people who are active during their leisure time look to be biologically younger than their channel- or web-surfing counterparts.

But don’t pass the holiday ham just yet. Human trials are several years away.
