Greasy hair gives polar bears fur with anti-icing properties
- An international team of scientists discovered that polar bear fur's sebum prevents ice from sticking, helping them survive in harsh climates.
- The study, published in Science Advances, reveals that cholesterol, diacylglycerols, and fatty acids in sebum contribute to its anti-icing properties.
- The findings could inspire new anti-ice materials for use in fabrics and outdoor gear, according to Richard Hobbs, a study co-author.
- Polar bears use 'still hunting' techniques, and the low ice adhesion on their fur aids in stealthy hunting, as noted by Bodil Holst, a study co-author.
