Researchers progress DNA-based computer

Researchers at Columbia University have developed a second-generation computer that uses DNA circuitry instead of silicon. MAYA-II is faster than MAYA-I but still lags far behind silicon in overall speed. Where the DNA-based circuitry is superior is in fluid analysis. And the researchers say their work points to a new generation of computers that will be able to detect viruses like West Nile or bird flu much faster than today's instruments. They add that the DNA-based computers are likely to allow the development of new instruments for the detection and treatment of a broad range of ailments. At some point, DNA-based computers may be inserted in the body to kill cancer cells, release therapeutics or detect disease at an early stage.
