Many scientists have contended that humans have evolved very little over the past 10,000 years. A few hundred generations was just a blink of the evolutionary eye, it seemed. Besides, our cultural evolution — our technology, agriculture and the rest — must have overwhelmed our biological evolution by now. A vast study, published on Wednesday in the journal Nature, suggests the opposite. Examining DNA from 15,836 ancient human remains, scientists found 479 genetic variants that appeared to have been favored by natural selection in just the past 10,000 years. (Zimmer, 4/15)

It can feel as if you are spinning out of control in a Tilt-A-Whirl ride at an amusement park. But there is nothing amusing about a sudden bout of vertigo and dizziness. Of the many age-related problems that pose a risk to adults in midlife and beyond, so-called vestibular and balance disorders can be especially dangerous—and joy-depriving—because they increase the risk of falls and fractures and can lead people to restrict their own movement for fear of triggering another episode.
