Scientists build DNA based computer

Posted by chrisd on from the computer?-you're-soaking-in-it dept.

Archangel Michael writes "Israeli scientists have built a DNA computer so tiny that a trillion of them could fit in a test tube and perform a billion operations per second with 99.8 percent accuracy. Yahoo News has the story"

    The Yahoo article is fairly content-free (and take a lot of space doing it). Here is the link to the the Weismann Institue abstract. http://www.weizmann.ac.il/math/users/lbn/public_ht ml/new_pages/Abstract.html
    Note that the 99.8% is what the abstract calls "Transition Fidelity" and is unclear what it means. I take it to mean that from input to output, the answer as read, is corret 99.8% of the time.

    It is interesting that they claim to be implementing a Turing machine. Previous uses of DNA has been mostly for the Travelling Salesman Problem with has a (more or less) natural mapping to DNA.
