In a twist that rivals cinema's best, a new study published Tuesday in Royal Society Open Science suggests a horrible truth: We've been the damn dirty apes all along. It found that beds made by one of our closest primate relatives, chimpanzees, contain little personal filth, meaning germs and parasites from their own body, and certainly much less filth than what's typically seen in human homes and beds.

Scientists have long speculated that the "dirtier" the environment we grow up in - with lots of germs from different people and even animals - the better off our immune system and physical health ultimately will be. A new study published Monday in Proceedings of the National Academy of Science provides early evidence that a dirty world might even be better for our mental health, too.

To the untrained eye, babies are nothing more than drooling, crying blobs who do basically nothing all day. But a recent study published in Environmental Science & Technology has found that babies are actually drooling, crying blobs who stir up impressive clouds of bacteria, dirt, fungi and bug bits wherever they crawl. And all it took to figure this out was creating a foil-covered robot baby.

For years, parents have been told to withhold peanut products from their children until the age of three. In a total flip-flop, the NIH has issued new guidelines recommending that babies be fed peanuts early in their lives to prevent the onset of dangerous allergies.
