'Science is
imagination in a straitjacket.’
American
physicist Richard Feynman
As a young
person, I had no idea what I wanted to do with my life. So often, children are
asked What do you wish to be when you
grow up, and my only answer was contented.
My parents
were both well educated and had high standards when it came to schooling and
the pursuit of a career but, in their own lives, neither was particularly
successful. I was raised in the extremes of privilege and then in poverty, and
neither seemed to much matter in terms of my happiness.
It was by
pure accident that I found my way to science. I like a good story. I’ve always
been a dedicated bibliophile, and I have done my share of writing. Science is
much like the process of authoring a work, except that in the context of the
sciences, we are constrained by all the things we know to be true, and we have
the facts and the tools to dissect the story we are trying to tell.
I also
like to travel but, on the earth, there is no landscape we have not yet
discovered. There are, however, an endless numbers of new things to learn about
the world and the way it works…the way our bodies work. In that regard, too,
science takes us in to the foray of the unknown.
My work in
microbiology and genetics became my life when I was diagnosed with Type 1
diabetes.
Diabetes
usually happens because a person doesn’t have enough of the hormone insulin,
which is the only hormone capable of lowering blood sugar concentration after a
meal. Every time you eat a Mars bar or Hershey bar, your blood sugar will begin
to rise and that insulin will call to your cells, depart the pancreas, and
cause the blood sugar to be lowered. It’s a beautifully orchestrated event that
comes together like the tiny pieces of a little jigsaw puzzle.
I spent a
long time after my diagnosis interested in the mystery of how that insulin
begins to rise, and what makes it know to beckon the cells. It’s actually a
fascinating event. A single protein acts like a tiny hole in the cell
membrane, and when this little pore opens up, it allows ions to pass through
it. Those ions are an electric current, and their movements based on that
single protein triggers a series of events that determine whether or not
insulin is secreted, and in what amount. Proteins, amino acids, are the stuff
of bone and tissue and life itself.
In the
same way, the miracle of exogenous insulin is no less impressive than the
wonder of that protein, the current of electricity that ignites the body’s
insulin, or the processes by which those mechanisms fail. In 1922, Dr.
Frederick Banting could never have imagined how drops from a vial would translate
into millions of lives saved.
Each time
I hold an insulin pen or pump in my hand, I remember that I am holding life itself.
My friend
Chris Scully (http://canadiandgal.blogspot.ca/)
posted about the realization that the whole of her health was contained in a
tiny insulin vial, and the reaction from others with diabetes ranged from the
frightened, “I try not to think about it,” to the fascinated, “Isn’t it amazing
that once upon a time, this simple serum didn’t exist?”
Today,
there are scores of dedicated scientists researching newer insulin
technologies, closed loop systems, the artificial pancreas and, yes, a cure for
diabetes. There are fundraisers and parents who work, tirelessly, to advocate
for new treatment applications and, in the process, refuse to allow diabetes to
become “someone else’s problem.”
Most
importantly, there are 350 million of us living with diabetes, finding the
strength to do all over again for another year.
As we head
into November and Diabetes Awareness Month, I want to pay my gratitude to all
those who work to keep me alive, to make my life better, to let me ride my bike
and run a marathon and to enable me to see my children grow up. Thanks for all
you do.
