Tiny motor turns giant rods (Mar 10)
http://physicsweb.org/article/news/10/3/9
Researchers in the Netherlands have made a light-driven nano-scale motor
that can rotate microscale objects that are 10,000 times bigger than
itself. The motor consists of a molecule embedded in a
liquid-crystalline film with a glass rod placed on top. As the molecule
changes shape, it alters the structure of the film, which in turn makes
the rod move (Nature 440 163).
