Why do we hate? Humans are capable of love and cooperation --so why do we treat each other with cruelty and violence? Evolutionary anthropologist Brian Hare searches for the origins of hate in our distant past, and in our contemporary environment.
There are 100 billion individual neurons in the human brain. Working together, they allow us to make sense of, and move through, the world around us. Scientists have built replicas of the human brain with computers, but no one has ever successfully made a brain out of humans. On this episode, I’ll travel back to my hometown of Stilwell, Kansas, and turn it into a working brain!
After millennia of speculation about what goes on inside the human brain, we now have the tools to explore its hidden reaches. These tools are leading to research that may help those suffering from afflictions such as epilepsy and Alzheimer's disease. They are also shedding light on the mystery of consciousness and what makes us who we are.
How does the creative brain work? Nancy Andreasen, neuroscientist and neuropsychiatrist, has spent her life studying the relationship between brain function, mental illnesses and the emergence and continuance of creativity.

If you think you are really in control of your life, you may have to think again.
