Engineers use heat-free technology to make metallic replicas of a rose's surface texture
Nature has worked for eons to perfect surface textures that protect, hide and otherwise help all kinds of creatures survive. There’s the shiny, light-scattering texture of blue morpho butterfly wings, the rough, drag-reducing texture of shark skin and the sticky, yet water-repelling texture of rose petals. But how to use those natural textures and properties in the engineered world?
