 When I was a kid I remember getting a Game Boy, you know, one of these handheld gaming devices the size of a small brick really and I remember my dad told me that the computing power of my Game Boy was as strong as the first lunar landing space shuttle computer and You know computers have just kept growing in power Actually on this dotted black line We see something like a proxy for the technology of computers and how it's grown over time But I want to draw your attention to the blue line here behind me as well And you can see that's also growing very fast. It's a slightly younger technology is the technology of DNA reading Now we know why we need computers otherwise. We couldn't play Candy Crush, but why do we need to read DNA? See DNA is a data set and it's hidden inside the cells of our body This data set is kind of like the code inside a computer. It tells the organism something about how to function and DNA evolved with life So it tells us something about our ancestry but it also tells us something about who we are today and in a hospital We might want to read DNA because sometimes DNA gets sick it can mutate and These tiny changes in the code that is what in some patients cause cancer One of the challenges to working with DNA is it's really really complex If just one patient coming into the doctor's office getting diagnosed with cancer We take out a few cells and we put it into one of these DNA reading machines We get the cancer DNA out. Let's say we want to print it on paper to show our doctor We're gonna get a stack of paper, which is 130 meters tall That's a lot of information not very nice for a doctor's read So I exploit that we have computer technology stronger than ever I take 130 meters of data and I put it into my computer and inside of there We tell the differences between the sick cell and the healthy cell because these Differences tell us something about why is the patient sick and maybe even what we can do about it In particular, I'm curious about a fact about healthy cell DNA Namely, there is an auto correct system When breaks happen, there's an auto correction scanning the code Preparing all the spelling errors in cancer cells. This system doesn't seem to work well enough And I think if we can understand the auto correction better It'll give us tools for understanding cancer evolution But also potential tools for how we can choose better treatment and develop better treatment So I believe in the future of medicine where we use the superpowers of Computer technology and DNA reading and giving doctors the best possible tools for providing patients for the best possible treatment
