(University of Bonn) Black fire beetles of the genus Melanophila possess unusual infrared sensors. Researchers from the University of Bonn and from the Forschungszentrum Jülich have concluded that the beetles' sensors might even be more sensitive that uncooled infrared sensors designed by humans. Having this natural model opens up new perspectives, such as for early warning systems for forest fires. The results have been published in PLoS ONE.
