Diginauts 0004 -- How Long Would You Like To Live, Copyright for Non-humans, New Words for Tech Concepts

We revisit some earlier segments to talk about big updates from this week, like President Obama pointing the U.S. towards Mars, efforts to stem climate change, and another accident involving a self-driving car.  Plus, we discuss whether animals have rights to their artwork, whether humans have reached the limits of their longevity, and the need for new words in the English language.
