Polar Bears: The Coolest Coat on Earth
Jun 18, 2025
Polar bear fur is more than just fluff—it’s frost-resistant! The bear’s fur is resistant to freezing, even after getting wet, a real plus in the bear’s frigid environment. Nano-physicist Bodil Holst recently learned why.
Polar bear fur has a unique combination of greasy compounds that keep it from freezing. When Holst and her team washed the bear hair of its greasy compounds, it lost most of its anti-icing capability. Researchers hope this finding will inspire the development of new anti-icing technologies.
Even in the frigid places polar bears call home, God equipped his creation with genetic diversity and traits to help them adapt to the extreme environments that came about after the flood. In his grace, he allows us to use features of creation to design new technologies that improve our lives in a fallen—and, in some places, frozen—world.
