Watch | Why these insects are outfitted with tiny 3D glasses

Insects fitted with tiny 3D glasses are helping scientists understand sight. This fascinating experiment shows how these mantises only try and catch simulations of food when the video is shown in 3D. Professor Jenny Read says her team's research at the New Castle University is a breakthrough that could lead to new ways of using three-dimensional vision in computers and robots. “Our mantis 3D glasses will be a great tool for studying 3D vision in insects - now we can make the experiments more complicated and build algorithms based on our research.”
