Researchers have discovered that the structural arrangements seen on a shiny Brazilian beetle may lead to futuristic computers that use light rather than electricity to process information. Scientists have long dreamed of computer chips based on light rather than electricity. In " optical computing" chips would need photonic crystals to channel light particles. Potentially these beetle scales could serve as a mold or template to which semiconductor material, like titanium or silica, can be added. The original beetle material can then be removed with acid leaving an inverse structure of the beetle crystal, a now usable photonic crystal in the visible light regions.
