Applying each group’s research strengths, the team demonstrated that the oils in polar bear fur contained a unique fatty acid profile that lent the hair its ice-resistant properties. The study, ...

The group compared ice resistance in samples of four materials: washed and unwashed polar bear fur, human hair and hair-based ski equipment coated in chemicals called fluorocarbons. They tested ...

To test how well the animals’ fur resists icing, researchers froze blocks of ice to samples of washed and unwashed polar bear ...
