Penguin’s Anti-Ice Trick Revealed
Bird feathers are known to have hydrophobic, or non-wetting, properties. But scientists from UCLA, University of Massachusetts Amherst and SeaWorld wanted to know what makes Antarctic penguins’ feathers extra ice repelling. “What we learn here is how penguins combine oil and nano-structures on the feathers to produce this effect to perfection,” explains UCLA mechanical and aerospace engineering professor Pirouz Kavehpour. The news was also carried in The Huffington Post; The Christian Science Monitor; Discovery News; the Daily Mail (U.K.); and the Daily Mirror (U.K.).
