A promising test for pancreatic cancer ... from a teenager

  • 0:01 - 0:05
    Have you ever experienced
    a moment in your life
  • 0:05 - 0:08
    that was so painful and confusing,
  • 0:08 - 0:10
    that all you wanted to do
  • 0:10 - 0:14
    was learn as much as you could
    to make sense of it all?
  • 0:14 - 0:18
    When I was 13, a close family friend
    who was like an uncle to me
  • 0:18 - 0:20
    passed away from pancreatic cancer.
  • 0:21 - 0:24
    When the disease hit so close to home,
  • 0:24 - 0:26
    I knew I needed to learn more.
  • 0:26 - 0:28
    So I went online to find answers.
  • 0:29 - 0:33
    Using the Internet, I found a variety
    of statistics on pancreatic cancer,
  • 0:33 - 0:35
    and what I had found shocked me.
  • 0:36 - 0:41
    Over 85 percent of all pancreatic cancers
    are diagnosed late,
  • 0:41 - 0:44
    when someone has less
    than a two percent chance of survival.
  • 0:46 - 0:49
    Why are we so bad at detecting
    pancreatic cancer?
  • 0:50 - 0:52
    The reason?
  • 0:52 - 0:55
    Today's current "modern" medicine
    is a 60-year-old technique.
  • 0:56 - 0:57
    That's older than my dad.
  • 0:58 - 1:01
    (Laughter)
  • 1:02 - 1:08
    But also, it's extremely expensive,
    costing 800 dollars per test,
  • 1:08 - 1:13
    and it's grossly inaccurate, missing
    30 percent of all pancreatic cancers.
  • 1:14 - 1:18
    Your doctor would have to be ridiculously
    suspicious that you have the cancer
  • 1:18 - 1:19
    in order to give you this test.
  • 1:20 - 1:23
    Learning this, I knew there
    had to be a better way.
  • 1:24 - 1:26
    So, I set up scientific criteria
  • 1:26 - 1:28
    as to what a sensor
    would have to look like
  • 1:28 - 1:31
    in order to effectively
    diagnose pancreatic cancer.
  • 1:31 - 1:33
    The sensor would have to be:
  • 1:33 - 1:38
    inexpensive, rapid, simple, sensitive,
  • 1:38 - 1:41
    selective, and minimally invasive.
  • 1:42 - 1:47
    Now, there's a reason why this test
    hasn't been updated in over six decades.
  • 1:47 - 1:50
    And that's because when
    we're looking for pancreatic cancer,
  • 1:50 - 1:52
    we're looking at your bloodstream,
  • 1:52 - 1:57
    which is already abundant in all these
    tons and tons of protein,
  • 1:57 - 2:01
    and you're looking for this miniscule
    difference in this tiny amount of protein.
  • 2:01 - 2:02
    Just this one protein.
  • 2:02 - 2:04
    That's next to impossible.
  • 2:04 - 2:08
    However, undeterred
    due to my teenage optimism --
  • 2:08 - 2:09
    (Laughter)
  • 2:09 - 2:14
    (Applause)
  • 2:14 - 2:19
    I went online to a teenager's
    two best friends, Google and Wikipedia.
  • 2:19 - 2:22
    I got everything for my homework
    from those two sources.
  • 2:22 - 2:23
    (Laughter)
  • 2:23 - 2:26
    And what I had found was an article
  • 2:26 - 2:30
    that listed a database
    of over 8,000 different proteins
  • 2:30 - 2:32
    that are found when you have
    pancreatic cancer.
  • 2:32 - 2:35
    So, I decided to go
    and make it my new mission
  • 2:35 - 2:37
    to go through all these proteins,
  • 2:37 - 2:41
    and see which ones could serve
    as a bio-marker for pancreatic cancer.
  • 2:41 - 2:43
    And to make it a bit simpler for myself,
  • 2:43 - 2:47
    I decided to map out
    scientific criteria, and here it is.
  • 2:48 - 2:52
    Essentially, first, the protein would have
    to be found in all pancreatic cancers,
  • 2:52 - 2:54
    at high levels in the bloodstream,
  • 2:54 - 2:57
    in the earliest stages,
    but also only in cancer.
  • 2:58 - 3:01
    And so I'm just plugging and chugging
    through this gargantuan task,
  • 3:01 - 3:04
    and finally, on the 4,000th try,
  • 3:04 - 3:06
    when I'm close to losing my sanity,
  • 3:06 - 3:07
    I find the protein.
  • 3:07 - 3:11
    And the name of the protein
    I'd located was called mesothelin,
  • 3:11 - 3:14
    and it's just your ordinary,
    run-of-the-mill type protein,
  • 3:14 - 3:18
    unless, of course, you have
    pancreatic, ovarian or lung cancer,
  • 3:18 - 3:21
    in which case it's found at these
    very high levels in your bloodstream.
  • 3:21 - 3:26
    But also, the key is that it's found
    in the earliest stages of the disease,
  • 3:26 - 3:28
    when someone has close
    to 100 percent chance of survival.
  • 3:29 - 3:32
    So now that I'd found
    a reliable protein I could detect,
  • 3:32 - 3:35
    I then shifted my focus
    to actually detecting that protein,
  • 3:35 - 3:37
    and thus, pancreatic cancer.
  • 3:38 - 3:41
    Now, my breakthrough
    came in a very unlikely place,
  • 3:41 - 3:44
    possibly the most unlikely
    place for innovation --
  • 3:44 - 3:48
    my high school biology class,
    the absolute stifler of innovation.
  • 3:48 - 3:51
    (Laughter)
  • 3:51 - 3:54
    (Applause)
  • 3:54 - 3:58
    And I had snuck in this article
    on these things called carbon nanotubes,
  • 3:58 - 4:00
    and that's just a long,
    thin pipe of carbon
  • 4:00 - 4:04
    that's an atom thick, and one
    50,000th the diameter of your hair.
  • 4:04 - 4:07
    And despite their extremely small sizes,
  • 4:07 - 4:08
    they have these incredible properties.
  • 4:09 - 4:11
    They're kind of like the superheroes
    of material science.
  • 4:11 - 4:15
    And while I was sneakily reading this
    article under my desk in my biology class,
  • 4:15 - 4:19
    we were supposed to be paying attention
    to these other kind of cool molecules,
  • 4:19 - 4:20
    called antibodies.
  • 4:21 - 4:23
    And these are pretty cool
    because they only react
  • 4:23 - 4:24
    with one specific protein,
  • 4:24 - 4:27
    but they're not nearly
    as interesting as carbon nanotubes.
  • 4:27 - 4:33
    And so then, I was sitting in class,
    and suddenly it hit me:
  • 4:33 - 4:37
    I could combine what I was
    reading about, carbon nanotubes,
  • 4:37 - 4:40
    with what I was supposed to be
    thinking about, antibodies.
  • 4:40 - 4:43
    Essentially, I could weave
    a bunch of these antibodies
  • 4:43 - 4:45
    into a network of carbon nanotubes,
  • 4:45 - 4:48
    such that you have a network
    that only reacts with one protein,
  • 4:48 - 4:52
    but also, due to the properties
    of these nanotubes,
  • 4:52 - 4:54
    it will change its electrical properties,
  • 4:54 - 4:56
    based on the amount of protein present.
  • 4:56 - 4:58
    However, there's a catch.
  • 4:58 - 5:01
    These networks of carbon
    nanotubes are extremely flimsy.
  • 5:02 - 5:05
    And since they're so delicate,
    they need to be supported.
  • 5:05 - 5:07
    So that's why I chose to use paper.
  • 5:08 - 5:10
    Making a cancer sensor
    out of paper is about as simple
  • 5:11 - 5:13
    as making chocolate chip
    cookies, which I love.
  • 5:13 - 5:15
    (Laughs)
  • 5:16 - 5:19
    You start with some water,
    pour in some nanotubes,
  • 5:19 - 5:24
    add antibodies, mix it up,
    take some paper, dip it, dry it,
  • 5:24 - 5:26
    and you can detect cancer.
  • 5:27 - 5:34
    (Applause)
  • 5:34 - 5:37
    Then, suddenly, a thought occurred
  • 5:37 - 5:41
    that kind of put a blemish
    on my amazing plan here.
  • 5:41 - 5:44
    I can't really do cancer research
    on my kitchen countertop.
  • 5:44 - 5:46
    My mom wouldn't really like that.
  • 5:47 - 5:50
    So instead, I decided to go for a lab.
  • 5:50 - 5:54
    So I typed up a budget, a materials list,
    a timeline, and a procedure,
  • 5:54 - 5:57
    and I emailed it
    to 200 different professors
  • 5:57 - 6:00
    at Johns Hopkins University
    and the National Institutes of Health --
  • 6:00 - 6:03
    essentially, anyone that had anything
    to do with pancreatic cancer.
  • 6:03 - 6:07
    I sat back waiting for these
    positive emails to be pouring in,
  • 6:07 - 6:09
    saying, "You're a genius!
    You're going to save us all!"
  • 6:09 - 6:11
    And --
  • 6:11 - 6:14
    (Laughter)
  • 6:14 - 6:18
    Then reality took hold,
    and over the course of a month,
  • 6:18 - 6:22
    I got 199 rejections
    out of those 200 emails.
  • 6:22 - 6:25
    One professor even went
    through my entire procedure,
  • 6:25 - 6:28
    painstakingly -- I'm not really
    sure where he got all this time --
  • 6:28 - 6:31
    and he went through and said
    why each and every step
  • 6:32 - 6:34
    was like the worst mistake
    I could ever make.
  • 6:34 - 6:39
    Clearly, the professors did not have
    as high of an opinion of my work as I did.
  • 6:40 - 6:42
    However, there is a silver lining.
  • 6:42 - 6:45
    One professor said, "Maybe I might
    be able to help you, kid."
  • 6:45 - 6:47
    So, I went in that direction.
  • 6:48 - 6:52
    (Laughter)
  • 6:52 - 6:54
    As you can never say no to a kid.
  • 6:54 - 6:57
    And so then, three months later,
  • 6:57 - 7:00
    I finally nailed down
    a harsh deadline with this guy,
  • 7:00 - 7:03
    and I get into his lab, I get
    all excited, and then I sit down,
  • 7:03 - 7:05
    I start opening my mouth and talking,
  • 7:05 - 7:08
    and five seconds later,
    he calls in another Ph.D.
  • 7:08 - 7:11
    Ph.D.s just flock into this little room,
  • 7:11 - 7:14
    and they're just firing
    these questions at me,
  • 7:14 - 7:16
    and by the end, I kind of felt
    like I was in a clown car.
  • 7:16 - 7:19
    There were 20 Ph.D.s,
    plus me and the professor
  • 7:19 - 7:20
    crammed into this tiny office space,
  • 7:20 - 7:23
    with them firing these
    rapid-fire questions at me,
  • 7:23 - 7:25
    trying to sink my procedure.
  • 7:26 - 7:28
    How unlikely is that? I mean, pshhh.
  • 7:28 - 7:32
    (Laughter)
  • 7:32 - 7:35
    However, subjecting myself
    to that interrogation --
  • 7:35 - 7:38
    I answered all their questions,
    and I guessed on quite a few
  • 7:38 - 7:40
    but I got them right --
  • 7:40 - 7:43
    and I finally landed
    the lab space I needed.
  • 7:44 - 7:48
    But it was shortly afterwards that
    I discovered my once brilliant procedure
  • 7:48 - 7:50
    had something like a million holes in it,
  • 7:50 - 7:52
    and over the course of seven months,
  • 7:52 - 7:55
    I painstakingly filled
    each and every one of those holes.
  • 7:55 - 7:56
    The result?
  • 7:56 - 8:01
    One small paper sensor that costs
    three cents and takes five minutes to run.
  • 8:01 - 8:04
    This makes it 168 times faster,
  • 8:04 - 8:07
    over 26,000 times less expensive,
  • 8:07 - 8:11
    and over 400 times more sensitive
    than our current standard
  • 8:11 - 8:13
    for pancreatic cancer detection.
  • 8:14 - 8:21
    (Applause)
  • 8:23 - 8:25
    One of the best parts
    of the sensor, though,
  • 8:25 - 8:28
    is that it has close
    to 100 percent accuracy,
  • 8:28 - 8:30
    and can detect the cancer
    in the earliest stages,
  • 8:30 - 8:33
    when someone has close
    to 100 percent chance of survival.
  • 8:33 - 8:35
    And so in the next two to five years,
  • 8:35 - 8:39
    this sensor could potentially lift
    the pancreatic cancer survival rates
  • 8:39 - 8:43
    from a dismal 5.5 percent
    to close to 100 percent,
  • 8:43 - 8:46
    and it would do similar
    for ovarian and lung cancer.
  • 8:46 - 8:48
    But it wouldn't stop there.
  • 8:48 - 8:50
    By switching out that antibody,
  • 8:50 - 8:53
    you can look at a different protein,
    thus, a different disease --
  • 8:53 - 8:56
    potentially any disease
    in the entire world.
  • 8:57 - 9:01
    So that ranges from heart disease,
    to malaria, HIV, AIDS,
  • 9:02 - 9:04
    as well as other forms
    of cancer -- anything.
  • 9:04 - 9:06
    And so, hopefully one day,
  • 9:06 - 9:09
    we can all have that one extra uncle,
  • 9:09 - 9:12
    that one mother, that one brother, sister,
  • 9:12 - 9:14
    we can have that one more
    family member to love.
  • 9:15 - 9:20
    And that our hearts will be rid
    of that one disease burden
  • 9:20 - 9:23
    that comes from pancreatic,
    ovarian and lung cancer,
  • 9:23 - 9:25
    and potentially any disease.
  • 9:25 - 9:28
    But through the Internet,
    anything is possible.
  • 9:28 - 9:29
    Theories can be shared,
  • 9:29 - 9:32
    and you don't have to be
    a professor with multiple degrees
  • 9:32 - 9:33
    to have your ideas valued.
  • 9:33 - 9:37
    It's a neutral space, where
    what you look like, age or gender --
  • 9:37 - 9:38
    it doesn't matter.
  • 9:39 - 9:40
    It's just your ideas that count.
  • 9:41 - 9:46
    For me, it's all about looking
    at the Internet in an entirely new way,
  • 9:46 - 9:48
    to realize that there's so much more to it
  • 9:48 - 9:51
    than just posting duck-face
    pictures of yourself online.
  • 9:51 - 9:53
    (Laughter)
  • 9:53 - 9:55
    You could be changing the world.
  • 9:56 - 10:01
    So if a 15 year-old who didn't even know
    what a pancreas was
  • 10:01 - 10:04
    could find a new way
    to detect pancreatic cancer --
  • 10:05 - 10:07
    just imagine what you could do.
  • 10:07 - 10:09
    Thank you.
  • 10:09 - 10:15
    (Applause)
