In India, one out of six people are branded impure from birth. They live in appalling circumstances at the bottom of the Hindu caste system and are considered "untouchable". Todd talks with writer Tom O'Neill about the "untouchable" people of India, why they are still treated so poorly, how they survive and how they are trying to defend their human rights. O'Neill is a writer for National Geographic Magazine.

There are many theories about the "birth" of the moon including the theory that the moon was once a flying object and became trapped in our atmosphere. However the current accepted theory of the origin of the moon is known as the "Big Splat" theory. Todd talks with science writer Dana Mackenzie about this theory and what it means. Mackenzie's book is called "The Big Splat: Or How Our Moon Came to Be".
