DNA Computer Detects, Treats Disease
Arthur Dent '99 writes "According to this article at Reuters, Israeli scientists at the Weizmann Institute have developed a DNA computer which can automatically detect and treat prostate cancer and a form of lung cancer in laboratory experiments. Theoretically, a person could be injected with this computer, and it would detect and treat any diseased cells at the earliest stages of development, perhaps preventing the disease altogether."
Instead of reading a vague description of their results try the following two links:

What they have done, which is cool, clever and generally admirable, is to add an input (detect protein A, or RNA strand B, etc.) that triggers an appropriate output (synthesise protein C, or make enzyme D to release drug E).
This is incredibly powerful - indeed it is 90% of the way to the 'magic bullet' that was the grail of cancer research a few years back (there's no method for delivery into the cell yet, but I'm sure a viroid shell for anti-cancer drugs is possible), and the guys deserve a Nobel prize for this if it lives up to its potential.
oh brave new world, that has such people in it!
