Light passing through glossy cocoon fibers spun by a Madagascar comet moth NORMAN SHI AND NANFANG YU/COLUMBIA ENGINEERINGInspired by the Madagascar comet moth (Argema mittrei), researchers at Columbia University School of Engineering and Applied Science have modeled synthetic fibers, which mimic the insect’s silk, transmitting light and images from one end to the other.

“This means we might be able to use them as a biocompatible and bioresorbable material for optical signal and image transport in biomedical applications,” says coauthor Nanfang Yu in a statement.
