Specifically, they manipulated the genes in a laboratory strain of a common virus, making the microbes collect exotic materials -- cobalt oxide and gold. And because these viruses are negatively charged, they can be layered between oppositely charged polymers to form thin, flexible sheets.
The result? A dense, virus-loaded film that serves as an anode.
A report on the work will appear in the April 7 issue of Science.
After so much stupidity, incompetence, corruption, and just plain evil exhibited by most politicians and officials involved with the construction of our 4-month-old-and-already-falling-apart-4-BILLION-US-DOLLAR Suvarnabhumi airport, it's uplifting to see ingenuity and inventiveness exhibited by our species.
