Computer Made From DNA And Enzymes

develop writes "Some folks from Israel have created a computer that runs on DNA and enzymes and is supposedly 100,000 times faster then today's PCs. Information at National Geographic, Telegraph UK and United Press." According to the National Geographic story, this DNA-based computer "can perform 330 trillion operations per second, more than 100,000 times the speed of the fastest PC." However, be aware that most of this is still future tense, and what these researchers have now is just a proof-of-concept.

    It may perform 330 trillion operations per second, but it has NO PRACTICAL APPLICATIONS for that computing power. (Read the stories).

    Granted that it's interesting....but it's not much further along than quantum computing.

    Also, I'm wondering if Guinness would recognize my computer where I mix two liquid chemicals together and they change color as a computer that can switch froms 0s to 1s more-or-less instantly and on a massively parallel scale ;-)

  2. How they measured 330 trillion calcs per second by coupland · · Score: 4, Insightful

    If you read the article you'll notice that this isn't a programmable computer. It's yet another test-tube experiment in which DNA was pre-programmed to return a pre-defined result, engaged in a chemical reaction, and then the resultant data read from the DNA at a later time. So while the experiment itself likely took many months or years, they claim that "330 trillion calculations per second" were performed because that's the duration of the chemical reaction divided by the number of bits of information that were changed. You can't ever access that data and you can't program the machine, but hell, that's how long the chemical reaction took... I'm decidedly unimpressed.

    Could this be a stepping-stone to one day being able to create simple life forms from scratch?

    Few viruses jump species, and by that I assume that the genetically altered machine wouldn't be the same as you or me.

    Of course one of the few cases of Ebola in the US came from monkeys. Then again Ebola is one helluvan exception. It's method of entry isn't even fully understood Folate gates perhaps?
