MIT Researchers Reveal Bacteria-Based Batteries

The solution to the age-old problem of weakening battery capacity may soon emerge thanks to tech wizzes at the Massachusetts Institute of Technology, or MIT. Scientists there have discovered an efficient way of powering electronic devices using ... bacteria-infused batteries. No, this isn't a late April Fool's joke or a long-lost X-Files plot. It's true; the new batteries use a kind of bacteria that can construct an anode after being protected by a layer of cobalt oxide and gold.
