Researchers Debut DNA-Powered Computer 158

An anonymous reader writes "Researchers at Columbia University and the University of New Mexico have built a DNA -powered computer that is unbeatable at Tic-Tac-Toe. Although it's much slower than a normal computer, the researchers say their proof-of-concept system could help them develop new techniques for sorting and analyzing viruses and DNA mutations."

        My pet rock is also unbeatable at Tic-Tac-Toe. She discovered the cunning (hehe, cunning stunt bonus!) strategy of never making a move. I've been forced to concede every game so far as hunger, thirst and a need to urinate ultimately win out over my drive to be the greatest Tic-Tac-Toe player on the block.

        I blame my DNA.

          Now wait a minute. It does not sound like you are trying very hard. Since you are waiting for the rock to make a move, you can go eat, drink, urinate, take a dump, sleep, have intimate relations, or anything else as long as you trust the rock not to cheat. If you wait it out long enough, the sun will eventually explode, and your rock will probably melt. Then you can claim victory and be the best. We all have goals, and the only way to achieve them is to persevere in the face of adversity.

      I would think you could rig up a second tile with DNA taken from the same source material. This could act as a unit test against mutations in the DNA that might affect the outcome on tile 1. If the mutant genes on the second tile suddenly produce some undesirable outcome, then toss the whole batch and start over again.

    Playing with MAYA-II takes a long time," Macdonald admits. The system needs between 2 and 30 minutes to compute each move and a second machine is required to translate the fluorescent signals generated each time into a move in the game.

    No wonder it wins, it bores you to death by taking so long and hopes you fall asleep or quit.

    Can anyone comment on how this is related (if at all) to a recent announcement in New Zealand about a new ability to "store and execute computer programmes within a microscopic DNA Pharmaceutical crystal"? [1] [scoop.co.nz] [2] [newswire.co.nz]. Supposedly (according to radio reports) the New Zealand group has been working for 20 years in secret (or something) until the press release in the past day or so.

    I'm wondering if it's a case of one group having announced in a rush so as not to be overshadowed by another group that's been working on the same thing.

      That press release ("a DNA Pharmaceutical Tablet...an entirely new form of Data Codon") is pure gibberish. Between the incoherent language, the weird secrecy and the fact that this seems to be a one man operation, I'd strongly suspect Graemme Brown is a crank.

      O(1) in time. Beautiful.

      Still exponential in space though; the volume of DNA solution needed ramps up exponentially with the complexity of the problem.

      IIRC even vaguely interesting TSP's would require an olympic-sized swimming pool.

      The DNA strand carrying the answer would appear in the pool in a very short time. I wonder how long it would take for a commercial PCR machine to find the DNA strand which carries that answer...

      No, no you can't. When you see a chicken playing tic-tac-toe, it's a trick whereby feed is released to the place that it's supposed to go to next.

      Granted, you're still right that tic-tac-toe is an amazingly simple game, and thus, that's not much of an accomplishment for a computer. Still, it's a proof-of-concept that their computer can run some logic, not a demo of the next AMD / IBM / Intel CPU technology.

        Hunh... really? I could've sworn that chicken I saw once didn't get any food until _after_ it had made its move, because I remember looking for something like what you're describing. Still, it's been years since I saw it, and I could be mistaken.
        • There are different variations. Some train the chickens to peck at spots that light up, and guide the chickens to the right place. Others display the correct move regardless of where the chicken actually tapped. Either way, the player will always be separated from the chicken in a way so that you can't see what's going on.

          Not that it still doesn't require some training of the chicken. And it's still entertaining to watch, but it's still a trick. Especially when you see people lose to the chicken. Wh

  • Cat's game snarks aside, this is genuine progress. Typically, a computer game version of tic tac toe plays by comparing the current board configuration against a collection of possible conditions, and determines the move that way -- or by scanning the board for possible win-in-one-move conditions and blocking them. In the first game, an unbeatable (it always wins or ties) game results (provided the collection of possible conditions/moves is accurate), and in the second case it's possible to win by creating
