Dance like no one is watching—or so they say. But people often are watching. Truth be told, they’re judging your moves. A study published last week in Scientific Reports used video of a variety of dancing women to pinpoint how observers distinguish good dancers from bad. If you care about such things, there’s one big takeaway: Swing those hips. And if you guessed all this has something to do with sex, you guessed right.
My reporting and writing on science, health, learning, parenting and other subjects has appeared in many publications including Newsweek, The New York Times, The Wall Street Journal, Scientific American Mind, Parents, and Redbook.

Picture two chimpanzees hanging out under a tree. One grooms the other, systematically working long fingers through fur, picking out bugs and bits of leaves.
