DNA computers!
    #1352419 - 03/05/03 10:59 AM (21 years, 29 days ago)

Israeli scientists have devised a computer that can perform 330 trillion operations per second, more than 100,000 times the speed of the fastest PC. The secret: It runs on DNA.

A year ago, researchers from the Weizmann Institute of Science in Rehovot, Israel, unveiled a programmable molecular computing machine composed of enzymes and DNA molecules instead of silicon microchips. Now the team has gone one step further. In the new device, the single DNA molecule that provides the computer with the input data also provides all the necessary fuel.

As of now, the DNA computer can only perform rudimentary functions, and it has no practical applications. "Our computer is programmable, but it's not universal," said Shapiro. "There are computing tasks it inherently can't do."

The device can check whether a list of zeros and ones has an even number of ones. The computer cannot count how many ones are in a list, since it has a finite memory and the number of ones might exceed its memory size. Also, it can only answer yes or no to a question. It can't, for example, correct a misspelled word.

that is pretty cool. I wonder how it compares to the quantum computer.

I was wondering the same thing. Quantum computing is really wild if you think this is neat, look here - Quantum Computing

Insert an "I think" mentally in front of eveything I say that seems sketchy, because I certainly don't KNOW much. Also; feel free to yell at me.
