Electrifying news about sugar.

Two scientists at the University of Massachusetts have discovered a sugar-loving micro-organism that may one day serve as a stable source of low power.

Described as sort of a bacterial battery, Rhodoferax ferrireducens feeds on and metabolizes sugar. The micro-organism's electrons, freed in the process, accumulate on an electrode in a fuel cell ... producing a current.

The so-called bacterial battery might one day be used in household devices that would draw on agricultural or other sugar-based waste for power.
