Most of us hope we’ll be healthy into our late 80s or early 90s and then die peacefully in our sleep, preferably after a wonderful evening with loved ones. But that’s rarely the way it works out.

Posted on Categories Discover Magazine

According to a recent study published in Science Advances, a greasy hair day keeps the ice away — for polar bears, that is. After examining polar bear fur, an international research team identified what helped keep polar bears ice-free, even in sub-zero temperatures. It all comes down to their greasy fur. “This work not only represents the first study of the composition of polar bear fur sebum, but it also resolves the question of why polar bears don’t suffer from ice accumulation,” sa ...read more
