We all know we have the power to make the world a bit greener – and many feel that includes messing with DNA for environmental improvements, or just better efficiency for our gadgets. Now there’s new hope that DNA could play a major role in making computers run with little or no external power.

Researchers at the University of Toyama say they have created the world’s first stable artificial DNA molecules, made from mainly artificial bits to resemble their natural counterparts. Their findings were published in the Journal of the American Chemical Society yesterday. Scientists from all over the world have been trying to do this for the promise of using artificial DNA to create biotechnology materials, including powerful DNA computers.

As Ruchi Mallya, an analyst on the use of technology in pharmaceuticals and biotechnology with Datamonitor, explains, such computers are constructed using DNA as software and enzymes as hardware, rather than traditional silicon-based components. This could then hopefully be the start of a new kind of external biological information storage system.
