概要

TLDRThe video highlights the incredible potential of DNA as a data storage medium, boasting a storage capacity far surpassing traditional methods like floppy disks and CDs. DNA can theoretically store up to a billion gigabytes in just a tiny space, lasting up to 500 years, even in harsh environments. Scientists have successfully experimented with encoding data into DNA, but the high costs and time involved currently hinder widespread adoption. As technology advances, these barriers are expected to decrease, making DNA storage a viable solution for the massive amounts of data generated daily.

収穫

  • 📼 Old storage mediums like floppy disks had very limited capacity.
  • 🧬 DNA can store vast amounts of data compactly and securely for centuries.
  • 🔢 DNA's base four encoding is akin to binary 0s and 1s in computing.
  • 🔬 Scientific experiments have successfully encoded large files in DNA.
  • 💸 High costs currently restrict DNA data storage's widespread use.
  • 📊 Enormous data production drives innovation in storage solutions.
  • 🎥 Video sponsored by Toyota, promoting futuristic thinking.

    The video begins by nostalgically referencing outdated storage devices like zip drives, 3 1/2 inch floppy disks, highlighting their limited storage capacity compared to modern devices. It contrasts this with a humorous note on how his current device, despite having 44,000 times more capacity, is larger simply because he needs a large screen. It suggests that the future involves not just thinking big, but also small, and introduces DNA as a revolutionary storage medium, capable of storing massive amounts of data in minuscule spaces.

    Anyone remember good old zip drives?

    Or hey, hey, how about these guys right here?
  • 00:00:16
    Or hey, hey, hey, here's an old favorite.
  • 00:00:20
    Right, you remember these?
  • 00:00:21
    No, it's not a 3D printout of your Save icon.
  • 00:00:25
    This is a 3 1/2 inch floppy disk,
  • 00:00:28
    and this little sucker could hold
  • 00:00:30
    a whopping 1.44 megabytes of information.
  • 00:00:35
    Wow, those were the days.
  • 00:00:37
    Today, I carry around a device
  • 00:00:39
    that has more than 44,000 times the storage capacity
  • 00:00:44
    of this sucker right here.
  • 00:00:46
    And the only reason this thing isn't
  • 00:00:47
    smaller than this thing is because
  • 00:00:50
    I'm old and I need a big screen
  • 00:00:52
    in order to read all those messages on Twitter.
  • 00:00:56
    It turns out the future isn't just about thinking big,
  • 00:00:58
    it's also about thinking small.
  • 00:01:01
    For example, what if we wanted to fit 150
  • 00:01:04
    of my smartphones, that would be the equivalent
  • 00:01:07
    of about 10,000 gigabytes on the head of a pin.
  • 00:01:12
    We can do that, if our storage medium is DNA.
  • 00:01:16
    DNA is the programming language of our genetic code,
  • 00:01:19
    and it depends upon four building blocks.
  • 00:01:21
    Adenine, Cytosine, Guanine, and Thymine.
  • 00:01:24
    And you can think of them as being similar
  • 00:01:26
    to the 0s and 1s we use in machine language.
  • 00:01:29
    It actually encodes information
  • 00:01:30
    that our cells depend upon for all their behaviors.
  • 00:01:33
    And DNA can store a lot of data in a very small space.
  • 00:01:38
    The theoretical limit for data storage in DNA
  • 00:01:41
    is an exabyte of data per cubic millimeter.
  • 00:01:45
    So you could store a billion gigabytes of data
  • 00:01:48
    in two ten-thousandths of a teaspoon.
  • 00:01:51
    This stuff can survive for up to 500 years,
  • 00:01:54
    even in harsh environments.
  • 00:01:56
    Compare that to the traditional storage media
  • 00:01:58
    we've used in the past, like CDs or floppy disks.
  • 00:02:01
    Those might last five or ten years
  • 00:02:02
    before being corrupted.
  • 00:02:04
    Even magnetic tape can only last between 15 and 30 years.
  • 00:02:08
    A few teams of computer scientists around the world
  • 00:02:11
    have been experimenting with ways to store data into DNA.
  • 00:02:14
    And they worked with bio-engineers to synthesize data
  • 00:02:17
    and build it block by block.
  • 00:02:20
    Back in April, 2016, a group of scientists
  • 00:02:23
    with the University of Washington
  • 00:02:24
    collaborated with Microsoft Research
  • 00:02:26
    to come up with a new means
  • 00:02:28
    of encoding information in strands of DNA.
  • 00:02:31
    They took the binary data of the file they wanted to encode,
  • 00:02:35
    and they converted it into base 4,
  • 00:02:37
    to match those four building blocks of DNA.
  • 00:02:40
    They then included ID tags that allowed them
  • 00:02:42
    to access any byte within a large pool of data.
  • 00:02:46
    They encoded four large files,
  • 00:02:48
    and they were able to access them almost perfectly.
  • 00:02:53
    Now the real barrier to adopting DNA storage
  • 00:02:56
    is that it takes a lot of money and time
  • 00:02:58
    to synthesize and sequence that DNA.
  • 00:03:01
    But bio-engineers are bringing those barriers
  • 00:03:03
    down every single day,
  • 00:03:04
    because they have incentive to do so.
  • 00:03:08
    In past episodes, you've heard us talk
  • 00:03:09
    about how much data we produce all the time.
  • 00:03:12
    Every day, it's about 25 billion gigabytes.
  • 00:03:15
    And there are companies that make money
  • 00:03:17
    by parsing all that data.
  • 00:03:19
    And there's a huge incentive to go
  • 00:03:21
    from enormous super center data reserve
  • 00:03:25
    to the size of a sugar cube.
  • 00:03:28
    It's pretty sweet.
  • 00:03:29
    But I've got a question for all of you guys this week.
  • 00:03:31
    If you encoded all of your computer's data in DNA,
  • 00:03:36
    and that DNA were then evolve into a life form,
  • 00:03:39
    what would that life form look like?
  • 00:03:41
    I'm prepared to be terrified in the comments below.
