For four billion years, what lived and died on Earth depended on two principles: natural selection and random mutation. Then humans came along and changed everything â€” hybridizing plants, breeding animals, altering the environment and even purposefully evolving ourselves. Juan Enriquez provides five guidelines for a future where this ability to program life rapidly accelerates. "This is the single most exciting adventure human beings have been on," Enriquez says. "This is the single greatest superpower humans have ever had."
As different as we humans are from one another, we all age along the same great sequence, and the shared patterns of our lives pass into the pages of the books we love. In this moving talk, journalist Joshua Prager explores the stages of life through quotations from Norman Mailer, Joyce Carol Oates, William Trevor and other great writers, set to visualizations by graphic designer Milton Glaser. "Books tell us who we've been, who we are, who we will be, too," Prager says. Watch Â»

What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus -- a 77-million-year-old sauropod that was as tall as a two-story house and as heavy as a jumbo jet -- and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth's geological history and contemplate our place in deep time. Watch Â»

We've been doing this for thousands of years: breeding, changing, mixing, matching all kinds of life-forms. This is not something new. The humble mustard weed has been modified so that if you change it in one way, you get broccoli. And if you change it in a second way, you get kale. And if you change it in a third way, you get cauliflower. So when you go to these all-natural, organic markets, you're really going to a place where people have been changing the lifecode of plants for a long time."
