Viruses "trained" to build tiny batteries - Yahoo! News:
"WASHINGTON (Reuters) - Researchers trying to make tiny machines have turned to the power of nature, engineering a virus to attract metals and then using it to build minute wires for microscopic batteries.

The resulting nanowires can be used in minuscule lithium ion battery electrodes, which in turn would be used to power very small machines, the researchers report in Friday's issue of the journal Science.
The international team of researchers, led by a group at the Massachusetts Institute of Technology, used the M13 virus, a simple and easily manipulated virus.
'We use viruses to synthesise and assemble nanowires of cobalt oxide at room temperature,' the researchers wrote."
