What new methods of analysis have been developed in the age-old struggle to discover if someone is telling the truth...or not? Some scientists have gone beyond the polygraph to model other ways of detecting whether we are getting a straight answer or being led down a crooked path.

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?

Follow the dramatic personal journey of Hugh Herr, a biophysicist working to create brain-controlled robotic limbs. At age 17, Herr’s legs were amputated after a climbing accident. Frustrated by the crude prosthetic limbs he was given, Herr set out to remedy their design, leading him to a career as an inventor of innovative prosthetic devices.
The Psychedelic Drug Trial has exclusive access to a ground-breaking new trial at Imperial College London. The trial sees, for the first time ever under controlled conditions, a psychedelic drug tested head-to-head against a standard antidepressant as a treatment for depression. The film follows a pioneering team of scientists and psychotherapists, led by Professor David Nutt, Dr Robin Carhart-Harris and Dr Rosalind Watts, as they compare the effects of psilocybin (the active ingredient of magic mushrooms) with an antidepressant (an SSRI called escitalopram) on a small group of participants with clinical depression. This is scientific research at its most cutting edge. With over seven million people being prescribed antidepressants each year in England alone, this drug trial is an important milestone in understanding a completely different treatment for depression.
