Sunlight reflected by solar cells is lost as unused energy. The wings of the butterfly Pachliopta aristolochiae are drilled by nanostructures (nanoholes) that help absorbing light over a wide spectrum ...

Scientists have found that a butterfly species from Australasia - Graphium sarpedon or common blueblottle - has 15 classes of light-detecting cells or photoreceptors, enabling them to see fast moving ...

Inspired by tiny nanostructures on transparent butterfly wings, engineers at Caltech have developed a synthetic analogue for eye implants that makes them more effective and longer-lasting. A paper ...
