Been a bit slack on the Science Story of the Day, but here we go.
A collaboration between Universitat Rovira and Swinburn University has revealed something very interesting about the wings of the Clanger Cicada. They physically destroy bacteria.
The video above demonstrates how the protubences on the wings of the cicada actually penetrate the cell walls of the bacteria, essentially ripping it apart. This has interesting potential for the development of future anti-bacterial materials, in that if it is possible to replicate this system, then the need for the use of harsh anti-bacterial chemicals can be reduced.
