Inspired by shark skin, researchers at Germany's Fraunhofer Institute have developed a new paint that could improve the fuel efficiency of aircraft and ships. The novel coating mimics the scales of sharks and dramatically reduces aerodynamic drag, relying on nanoparticle characteristics to withstand high speeds, UV radiation, and extreme temperatures.
