Scientist Finds Way To Control DNA-based Computations

By - Source: NCSU | B 24 comments

A scientist at North Carolina State University (NCSU) has found a way to control a logic gate in a DNA-based computing system.

The discovery could lead to computing chips that integrate both DNA molecules as well as traditional chip architectures built with silicon to create higher performing semiconductors in the future.

According to Alex Deiters, associate professor of chemistry at NCSU, DNA computing has tremendous potential as DNA has the ability to store much more data than silicon-based chips, but DNA is difficult to control. In fact, DNA computation are rather random acts – even the when and the where cannot be controlled. For this reason, scientists have been struggling with the creation of DNA computation sequences.

Deiters said that he was able to control DNA by "photocaging" portions of the DNA strands. By exposing the DNA to UV light, the scientist said that he "successfully photocaged several different nucleotides on a DNA logic gate known as an AND gate." UV light caused a computational event to be initiated and completed. Deiters now hopes that photocaging will enable scientists to create more complex computational processes and enable interfaces between silicon and DNA-based computers.

    Some day a computer virus will be able to infect the user.

    Yeah, hi doc....my computer has a virus. Can you burn some Nyquil to a a CD? It can't seem to hibernate, otherwise.

    DNA Computation has SKYNET written all over.
    Now we know who started it all.

    "Sir, I was just trying to say, they hacked your firewall in 10 seconds. Okay. Even a supercomputer with a brute force attack would take 20 years to do that...The signal pattern is learning. It's evolving on its own. And you need to move past Fourier transfers and start considering quantum mechanics...What about an organism? A living organism? Maybe some kind of DNA based computer? And I know that that sounds crazy... " Maggie Madsen - Transformers Movie

    I just can't wait for DNA computing to be mainstream. I want to upgrade my vision with some mid-range NVIDIA gpu.

    That is the future, and with full sensory immersion too. Just don't look at WoW or Diablo for that. Look instead at the pr0n industry.

    ultimate computer combo DNA geranium quantum based super computer. maybe a reality in my life time could be very interesting, if 'IT' don't go off in the wrong direction with it... matrix... terminator....

    Bruce Willis as FBI Agent Tom Greer will terminate all the Surrogates, so I'm not to worried.

    This just gave me a great idea for a movie. Imagine Neo entering the Matrix to help John Connor go to the past and destroy Skynet before the machines take over the Matrix in the present with the help of Agent Smith. It's a mashup of The Matrix, Terminator, Inception and Dude Where's my Car. What? It's still better than any Uwe Boll movie.

    DNA computing should be a natural for programming loops.
    Going around and around and around... :D
