    Somewhere Over The Brainbow: The Journey To Map the Human Brain

    The government-funded plan could cost $3 billion, take 10 years and involve hundreds of scientists. The hope is the project can unlock the secrets of conditions such as Alzheimer's, schizophrenia and Parkinson's disease. But progress will likely be slow, and in the end, will it be worth the cost?

    Gripping Science Tales Need Not Be Science Fiction

    When does a story about science become science fiction? Cosmologist Lawrence Krauss and theoretical physicist Brian Greene discuss how to spin a yarn about string theory or the Big Bang, without hyping the science. And novelist Ian McEwan, whose books touch on neurosurgery and quantum field theory, talks about what science offers to fiction.
