The thick pelt that helps polar bears to survive frigid Arctic winters has inspired a warm, sturdy fiber. Inspired by the microstructure and thermal insulation function of the polar bear hair, a research team led by Professor BAI Hao with ZJU’s College of Chemical and Biological Engineering has used a freeze-spinning technique to continuously fabricate silk fibroin solution into a fiber with aligned porous microstructure.

One ant species in the Sahara Desert is covered by a silvery sheen of body hair that acts as a wearable sun shield for the creatures, a new study finds. The silvery hairs completely reflect the light like mirrors, preventing the ants from absorbing too much heat. That may help to explain how the Saharan silver ants can stay cool when temperatures in the arid region reach a blistering 122 degrees Fahrenheit (50 degrees Celsisus).
