Saharan silver ants can control electromagnetic waves over extremely broad spectrum range

Nanfang Yu, assistant professor of applied physics at Columbia Engineering, and colleagues from the University of Zürich and the University of Washington, have discovered two key strategies that enable Saharan silver ants to stay cool in one of the hottest terrestrial environments on Earth. Yu's team is the first to demonstrate that the ants use a coat of uniquely shaped hairs to control electromagnetic waves over an extremely broad range from the solar spectrum (visible and near-infrared) to the thermal radiation spectrum (mid-infrared), and that different physical mechanisms are used in different spectral bands to realize the same biological function of reducing body temperature. Their research, "Saharan silver ants keep cool by combining enhanced optical reflection and radiative heat dissipation," is published June 18 in Science magazine.

You don't really associate a coat of fur with ants- that so strange and cool at the same time.
