Meet the scientific accident that could change the world

Last year, researchers at UCLA made a rather fantastic, if serendipitous, discovery. A team of scientists led by chemist Richard Kaner had just finished devising an efficient method for producing high-quality sheets of the Nobel-prize winning supermaterial known as graphene — with a consumer-grade DVD drive. That was groundbreaking in and of itself, but the real surprise came when Maher El-Kady, a researcher in Kaner's lab, wired a small square of their high quality carbon sheets up to a lightbulb. Then something incredible happened.
