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

(Applause)
