    Hell yeah! Hell no!

    DNA data storage

    Holy crap this is extremely awesome I wonder how long are we talking till its commercially available also how the heck do I get in on the ground floor?

    Interesting. I wonder how stable of a medium it is though. Organic matter has a relatively short shelf life and DNA is a tad unstable by virtue of it's own nature.

    I don't know they have been able to pull DNA out of some pretty ancient things. So I am going to assume its more stable than tape, Solid State, and of course spinning platers.

    I thought this was going to be an article about Mrs. Sock.

    That old DNA is incomplete though. Horribly fractured with big pieces missing. Fosil DNA is what we would reffer to as a "corrupted file" in the digital biz.

    The most complete fosil DNA records (mamoth for instance) were preserved under conditions that would lend longevity to any of our current media. (cold, anemic, and or dry)

    The fact that their is any sorts of fossil DNA shows how resilient it is, I am sure that when stored in an optimal way should make for fairly stable median.

    DNA is pretty stable, especially if one were to pair it with a repair system, maybe like those that repair UV light damage/thymine dimers. They mentioned using PCR in the video to amplify strands, Taq polymerase is the critical piece of this process. It was captured from a thermophillic bacteria from a hot spring in Yosemite national park. The higher heat stability and improved activity at ~75C makes it critical to the PCR process and most importantly, it doesn't require a cell to complete the reaction process, just give it a supply of bases, some magnesium, etc and it does its thing.

    The real benefit, though is the massive storage capacity of DNA as noted in the video.

    And what if some bacteria gets into your bio drive, reads your DNA based copy of something and gets the ability to wipe out mankind because of the particular sequence?
    Just thinking worst case scenario.

    Yes, that is a good point. This kind of storage would require sterile storage conditions, especially considering many human pathogens destroy DNA with DNase enzymes, etc.

    Bacteria is going to learn how to wipe out mankind by devouring countless hours of cat videos?
    Do you not understand how this works at all?
