Just 15 years ago, scientists successfully mapped the human genome, identifying all the genes that make us who we are. These genes determine our eye color and our blood type. They affect our height, our risk of heart disease, how strong our bones are, and even our body odor. And sometimes they cause life-threatening diseases like cystic fibrosis and breast cancer.
Now we have the technology to edit our genes. Scientists have figured out how to reprogram an ancient bacterial immune system called “CRISPR” to track down and edit genes in any organism, allowing us to tinker with the source code of life.
Some researchers believe this is the future of medicine — that we could cure genetic diseases and massively reduce human suffering. But it also raises some thorny ethical questions. Could it be used for enhancement, not just diseases? Should we edit the DNA of human embryos?
How far is too far?
Vox tackled this question in the second episode of our new show with Netflix, Explained. We’ll have new episodes every Wednesday, on topics ranging from gene editing to monogamy to the racial wealth gap, and more. If you like our videos, then you’ll love this show; it’s our most ambitious video project to date.
