For polar bears, the insulation provided by their fat, skin, and fur is a matter of survival in the frigid Arctic. For engineers, polar bear hair is a dream template for synthetic materials that might ...

For engineers, polar bear hair is a dream template for synthetic materials that might lock in heat just as well as the natural version. Now, materials scientists have developed such an insulator, ...

Frequently, when looking for answers to human problems, scientists turn to animals who have already evolved their own solutions. So when it came time to develop a heat-trapping fabric, a team of ...
