“Unwashed, greasy hair made it much harder for ice to stick. In contrast, when the polar bear hair was washed and the grease largely removed it performed similarly to human hair, to which ice sticks ...
“We measured ice adhesion strength ... researchers studied fur samples from six wild polar bears. The research team found that polar bear fur has remarkably low “ice adhesion strength.” That means ice ...
Polar bears don’t have to worry about skipping a wash day. The sebum, or natural oil, on the mammals’ fur helps them survive ...
This experiment showed that the ice adhesion of unwashed polar bear fur is exceptionally low. While the often-accepted ...

The Rochester Americans have announced the return of the “Teddy Bear Toss” to blue Cross Arena. On Saturday, February 22, the ...
The oily bear fur and the PFAS-laden ski equipment resisted adhering to ice, compared ... a biologist with Polar Bears International who was not involved in the study. “When we get them on ...
Indigenous knowledge about polar bears and reports on polar bear behaviors have led to questions about ... how evolution has optimized the sebum’s composition to avoid ice adhesion. We found squalene, ...
“We found squalene, a common lipid in other marine mammals, was almost entirely absent in polar bear fur. Our computational simulations revealed squalene strongly adheres to ice, and this ...
A wintry mess was bearing down on mid-Atlantic states Tuesday with forecasts of significant snow and ice accumulations prompting ... “When it gets this cold, we kind of pull out all the stops, ...
