Polar bear and insulation

Polar bear and insulation

S2 Ep 23. The science behind some fascinating fur could help humans keep warm in space. A polar bear’s fur is brilliant at insulating it from freezing arctic temperatures. Each shaft of hair contains multiple chambers which trap heat close to the skin, making it an incredible thermal insulator. Now, scientists have copied its structure to build a light and flexible material which may be useful for the aerospace industry.
