MIT uses gm virus to build batteries

Researchers at MIT have modified viruses through genetic engineering and directed evolution to build highly efficient batteries.

WOW indeed. Very interesting read thanks.

from Virus-Assembled Batteries
One of the ways they have done this in the past is using a process called "directed evolution." They combine collections of viruses with millions of random variations in a vial containing a piece of the material they want the virus to bind to. Some of the viruses happen to have proteins that bind to the material. Isolating these viruses is a simple process of washing off the piece of material --only those viruses bound to the material remain. These can then be allowed to reproduce. After a few rounds of binding and washing, only viruses with the highest affinity for the material remain.

My pleasure, Technologyreview is a must-have in your RSS feeds. There is a big Biotech section with all sorts of weird and wonderful stories. Another interesting one I recall (will have to go and look for the link) is about gm bacteria used to produce diesel from plant cellulose.
