"Hornets and wasps are unique in that, even in the absence of sweat glands, they are able to buzz around at temperatures of 40 degrees Celsius without overheating. A new theory presented by Jacob Ishay and colleagues at Tel Aviv University suggests that hornets may keep cool by using their cuticle as an electrical heat pump. The team believes that hornet cuticle is comprised of a stack of thermocouples, which transfer heat from one type of conductive material to another when voltage is applied. The voltage in this scenario would be the hornet's own metabolism, or conversely, solar energy." (Courtesy of the Biomimicry Guild)
