First solar-powered nano motor

An international team of scientists has created the first molecular motor powered solely by sunlight. By acting like pistons that move back and forth, these motors, which are only nanometers or billionths of meters across, could help read out data as ones and zeroes "for molecular photonics and electronics, two rapidly growing fields aimed at the construction of chemical computers," said researcher Vincenzo Balzani, a chemist at the University of Bologna, Italy.

I'll say it again: science for its own sake is awesome. To hell with rationlizing it. Do it just to do it.
