Shark skin inspires better planes, cars


Harvard scientists have developed a new structure inspired by shark skin that could improve the aerodynamic performance of planes, wind turbines, drones and cars. The study published in the Journal of the Royal Society Interface sheds light on a decades-old mystery about sharkskin.
Sharks and airplanes are not actually all that different. Both are designed to efficiently move through fluid, using the shape of their bodies to generate lift and decrease drag, researchers said. The difference is that sharks have about a 400 million-year head start on the design process, they said.
