Beetles to the rescue in disasters

Scientists develop 'backpacks' to steer bugs in confined spaces

SINGAPORE - A swarm of beetles, carrying tiny computers as backpacks, could one day be crawling through cracks and crevices in search of survivors during rescue missions.

Researchers from Nanyang Technological University in Singapore have developed what they say is the world's smallest cyborg insect, which they can move right and left, backward and forward, with the click of a button.
