Caption: Each Dec., the editors of Science reflect back upon the major scientific discoveries of the year and choose one which they believe to be the most significant. In 2013, the journal has given the distinguished title of Breakthrough of the Year to cancer immunotherapy, a tumor-targeting strategy that holds immense promise. This animation from the AAAS Office of Public Programs features this groundbreaking achievement, as well as nine runners-up that made big waves this year. The information about the Breakthrough of the Year appeared in the 20 Dec., 2013, issue of Science, published by AAAS.
