ONLINE COVER Nature's Origami. The wings of a ladybird beetle can sustain large aerodynamic forces during flight, and, when folded, these wings are deployable within 100 milliseconds. The self-locking and elastic energy storage capabilities of these wings are enabled by a tape-spring shaped vein in the wing frame. Baek et al. replicate the curved geometry of these veins to create origami structures that can self-lock and deploy within 116 milliseconds. The researchers validate their design by demonstrating a jumping robot and a jump-gliding robot with enhanced kinetic and static behavior. This month's cover shows how a ladybird beetle deploys its wings to take flight. [CREDIT: MYN/Marc Pihet/Minden Pictures]
