When insects land on the walls of Nepenthes pitcher plants, they soon meet their doom, thanks to a surface that causes them to slip into the digestive juices at the plant’s bottom. By mimicking the pitcher plant’s slick means of gathering a meal, Joanna Aizenberg and colleagues at Harvard University have created an omniphobic material that repels simple liquids such as water and hydrocarbons, complex fluids such as crude . . .
