Humboldt penguins live in places that dip below freezing in the winter,and despite getting wet, their feathers stay sleek and free of ice. Scientists maintain now figured out what could create that possible. They report in ACS' Journal of Physical Chemistry C that the key is in the microstructure of penguins' feathers. Based on their findings, or the scientists replicated the architecture in a nanofiber membrane that could be developed into an ice-proof material.
