Surgeon Peter Attia sees a disconcerting paradox at work when it comes to our health: while people are talking about eating healthily and exercising perhaps more than ever, we’re seeing no reduction in the rates of obesity and diabetes.

The many-headed dragon of public anger has a mouthful of fire for parents who don't vaccinate. But such scolding misses the mark, alienating caring parents who just want their kids to be safe. When measles broke out at California’s Disneyland in 2015, sickening nearly 150 people across seven states and spreading to Mexico and Canada, the online...

We have over 600 muscles in our bodies that help bind us together, hold us up, and help us move. Your muscles also need your constant attention, because the way you treat them on a daily basis determines whether they will wither or grow. Jeffrey Siegel illustrates how a good mix of sleep, nutrition and exercise keep your muscles as big and stron...

At the INK Conference, she talks through her new research, discovering healing cells in some surprising places.

We have lots in common with our closest primate relatives. But comparatively, humans seem a bit... underdressed. Instead of thick fur covering our bodies, many of us mainly have hair on top of our heads— and a few other places. So, how did we get so naked? And why do we have hair where we do? Nina G. Jablonski explores the evolution of human hai...
