Our brain is always making decisions - Nigel explores how it does this, and if we can help it to make better ones? Is it possible to change the brain we’re born with to a supercharged brain?

Alzheimer's disease -- the most feared of all maladies, with no way to cure, stop or even slow its insidious progression. But now, after decades of perseverance in the lab, researchers are on the cusp of a scientific breakthrough that could be the first step toward making Alzheimer's itself a distant memory. In the gripping new documentary Turning Point, acclaimed filmmaker James Keach takes us inside the quest for the first medication that that could treat the underlying process of Alzheimer's disease, more than a century after Dr. Alois Alzheimer first described the brain disorder that slowly destroys memory and cognitive skills. Along the way, we meet the people behind these grand experiments, the scientists driven as much by personal conviction as professional innovation. And we discover why medical science is never easy, often unpredictable and potentially perilous.

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?
For most of human history, our brains dealt with pretty straight forward problems. But that brain is the exact same one we now use to post pictures of our pets on social media, fill out Excel spreadsheets, and worry about the next payment on our credit card.
