Light bends matter
While it’s easy to see matter bending light – just look through a prism – it’s rare to find light bending matter. But scientists saw just that in an experiment reported in March 2010. Researchers assembled flat ribbons of nanoparticles – tiny bits of matter only billionths of a meter long – in a darkened laboratory.
Then when the ribbons were exposed to light, they curled up into spirals. The results could help engineers design new types of optics and electronics.
