We humans love to build, create, and organize. So why do we also love to destroy things? Can violently breaking stuff really help to calm us down, or does it just make us more angry? In this episode of Mind Field, I take a hard look at our urge to destroy.
Memory is not a photo album where your images of the past are faithfully recorded. The latest neuroscience discoveries show that memory can be affected in many ways and with surprising results: false memories, distortions, modifications and deja vu. To what extent can we rely on our memories?

Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches…the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence? The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. NOVA Wonders looks at how far we’ve come and where machines are headed as their software becomes ever more…cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?
A baby's brain is a mystery whose secrets scientists are just beginning to unravel. The mystery begins in the womb -- only four weeks into gestation the first brain cells, the neurons, are already forming at an astonishing rate: 250,000 every minute.
When examining the adolescent brain we find mystery, complexity, frustration, and inspiration. As the brain begins teeming with hormones, the prefrontal cortex, the center of reasoning and impulse control, is still a work in progress. For the first time, scientists can offer an explanation for what parents already know -- adolescence is a time of roiling emotions, and poor judgment.
