Carbon-14 is well known for its use in measuring the ages of very old things. But it's now being used in some surprising fields of research. And its improved accuracy is rewriting history. It found a 10-thousand year mistake in the dating of an Antarctic ice shelf collapse. In lakebed sediments, it shed new light on the history of Mount Fuji's eruptions. In marine biology, it can be used to trace whale movements, and more! We'll look at some of these exciting new applications.
