Lights, camera, action! Well maybe not a Hollywood movie, there is a lot to be learned by filming bees. Dr. Biology talks with bee movie maker and neurobiologist Brian Smith. Listen in as the two talk about bees, Bee Movie, and even take trip inside a beehive to check out what is buzzing.

Thousands of orange and black shapes flutter through the trees. Welcome to one of the few wintering homes of the monarch butterfly. Also in: Spanish

An interview with biologist David Pearson, an author and expert on tiger beetles. Did you know that tiger beetles can run so fast that they go blind and just what would it be like to be hunted by these tiny, but ferocious animals? These are a few of the questions that we learn the answer from our guest biologist.
