Viruses in Space: Cancer at Home | Madison Campbell | TEDxLincolnSquare


[Music]
imagine you’ve given up your life on
earth to create a new world on Mars
you’ve signed up for a three-year
mission that will involve getting on a
spaceship living in a capsule full of
people you’ve never met cohabitating
with a hundred heterogeneous professions
amongst other stressors you’ve yet to
find out about now I want you to look
around the room this is our spaceship
you’re the engineer you’re the chef
you’re the physicist and you’re the
doctor
a tiny society each of us with a
critical role to play both on Mars but
also along the way now I want you to
think about the fact that we’re all
about to get really really really sick
the microgravity of space travel will
degrade your bones and atrophy your
muscles well the cosmic radiation of
deep space will bombard your DNA and
basically create chaos seen only by
victims of nuclear bombs over time our
tiny society will have to deal with the
consequences remember the chef here well
whenever she gets sick not only will you
be taking care of her but you’ll also be
flipping flapjacks I bed pants Ivy’s
around the clock help I hope your second
profession was nursing let me give you
an example scott kelly has spent more
time in space than any other human on
the face of the planet and we know from
studying his experience exactly what
long-term exposure to space does to the
human body first comes the rashes then
the weakness and then the impairment in
eyesight eventually his exposure to
radiation was equivalent to 10 chest
x-rays every single day which is 30
times more than any other human being on
earth every day he is playing Russian
roulette with fatal cancers when Kelly
came home he was a mess and he was only
up there for about a third of the time
to get to and from Mars when the first
pioneers crossed the Atlantic Ocean they
were scared they had no idea what they
were getting themselves into this brave
new frontier were about to embark on
does not look like Star Trek it looks a
lot more like the Nina the Pinta and the
Santa Maria pioneering space is
something that many scientists and
adventurers alike want to see happen and
I want to see that happen too but the
truth is we have no idea and what the
harsh environs of space will do to the
human body and we have no idea what that
means for us on our mission to Mars but
okay guys there is a silver lining but
first we need to talk about space
viruses let me take you back to earth
for a second okay remember growing up
when you would share drinks with your
friends at birthday parties when germs
were something that you called cooties
but you didn’t acknowledge them remember
your first kiss okay sometime along that
way you caught a little virus called
epstein-barr virus this virus you might
otherwise known as mononucleosis or the
kissing disease this virus which is
living peacefully inside of you right
now is doing just fine
it a will live inside of you for the
rest of your life going completely
unnoticed just kind of like your crush
at work well what can I say um some of
you have been symptomatic of the disease
while others will claim that you’ve
never felt signs of it this is wrong
almost all humans are carriers of
epstein-barr virus whether or not you’ve
showed signs of it girl I know what you
there are circumstances under which the
virus will reactivate when you’re least
expecting it when you have decreased
immune functionality the virus
reactivates when you’re stressed the
virus reactivates the virus will
reactivate into cancer which could cause
your ultimate demise or mononucleosis
which no big deal they just leave you
tired for days on end okay so basically
decreased immune system and stress
that’s basically in the Welcome pamphlet
for a mission to Mars the environment of
space is a cold harsh fallowing one one
that leaves the worst for your body and
the worst in epstein-barr when I first
started started studying epstein-barr
virus and the environment of space
I thought the answer was research right
if we understood and we research more
about what epstein-barr virus does and
maybe we can understand how to solve it
okay but the problem here is that in
order for us to research and understand
epstein-barr virus and astronauts we’d
have to recreate that environment here
on earth
okay so hands up anyone who wants to be
inundated with radiation and be strapped
to bed for three years but it’s in the
name of science okay so basically the
point is no medical review board would
ever approve that type of experiment
okay so we could experiment on mice but
pity the poor mice epstein-barr virus is
such a nasty beast of a disease that
once the mice get it they’re probably
going to die so the point here is
basically the only thing we can do is
observe astronauts whenever they go to
space these poor brave souls that are
going to make the first mission are kind
of our best test subjects and I know
I’ve kind of painted going to Mars it’s
a death sentence but it’s likely one to
teach humanity important lessons about
the way illnesses work in the human body
about the way astronauts suffer the way
they feel pain and yes the way they die
and and the way they get cancer but once
we know
the actual cause of a problem we are
that much closer to the solution the
solution how did your cancer look space
sucks but it’s also beautiful
it’s where Humanity is heading for and
it’s basically going to be the only
thing that provides for us once the
earth is kaput but how do we get there
in one piece from an epidemiological and
viral article perspective there are a
lot of things that we need to work out
before we make our trip to space but by
studying these astronauts and by
studying infectious disease we will know
so much more not only about the
astronauts but also about people on
earth that suffer from cancer and and
mononucleosis in so many diseases this
little virus which we don’t acknowledge
might be able to cure cancer cure cancer
check colonize a new land check this
little virus that we don’t acknowledge
might be able to turn the world on its
head thank you
