Divining nanorods

Tiny fibrous carbon nanorods can "harvest" water from the atmosphere according to scientists at Pacific Northwest National Laboratory who noticed the strange phenomenon by accident. Fibers on the surfaces of desert-dwelling plants often display this property, but a synthetic material that might be manufactured into a technically viable system might be used to trap water from the air or act as sweat-absorbing wicking material for sportswear or military clothing. Chemist Satish Nune was inspecting the solid, carbon-rich nanorods with a vapor analysis instrument when he noticed the nanorods mysteriously lost weight as humidity increased.
