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?

What Are Animals Saying?

From singing whales and squeaking bats to thumping spiders and clicking dolphins, the world is filled with the exotic sounds of our fellow creatures. What are they saying? While we believe language sets us apart, some animals demonstrate they can learn our language—like Chaser the dog, who recognizes hundreds of words, and Kanzi the bonobo, who appears to have a sophisticated understanding of spoken English. But can we decode their own communications? NOVA Wonders follows researchers around the globe who are deciphering an amazing array of clues that reveal how animals share information critical to their survival. Will we one day be able to write the bat dictionary or decode the hidden sign language of chimps? And what can these findings tell us about the roots of our own language?

What's Living in You?

Whether they make you fat, fart, or freak out, microbes play a central role in your life. Right beneath your nose—on your face, in your gut, and everywhere in between—trillions of bacteria, viruses, and fungi are so abundant in your body, they outnumber your human cells. But these aren’t just nasty hitch-hikers. Many are crucial to your survival. Evidence suggests that a diverse microbiome can keep you healthy and, conversely, a damaged one could kill you. NOVA Wonders peers into this microscopic world to discover the fascinating, bizarre, and downright surprising secrets of the human microbiome, including the world’s largest stool bank, which transforms raw stool into life-saving poop pills.

Can We Make Life?

"It's alive!" Since Dr. Frankenstein spoke those famous words, we've been alternately enthralled and terrified by the idea of creating life in the lab. Now, a revolution in genetic engineering and thrilling innovations in synthetic biology are bringing that dream—or nightmare, as the case may be—closer to reality. New tools allow researchers to use cells to create their own DNA and edit it into existing genomes with more ease and less cost than ever before. Along with renewed hopes for treating some genetic diseases, there's serious talk of using the newest technologies to bring long-extinct animals back from the dead – like the team hoping to resurrect the woolly mammoth. Science fiction is quickly becoming science fact. NOVA Wonders explores the benefits and the burden of risk surrounding the controversial new technology

What's the Universe Made Of?

The universe is hiding something. In fact, it is hiding a lot. Everything we experience on Earth, the stars and galaxies we see in the cosmos—all the “normal” matter and energy that we understand—make up only 5% of the known universe. The other 95% is made up of two mysterious components: “dark matter” and “dark energy.” We can’t see them, but we know they’re there. And what’s more—these two shadowy ingredients are locked in an epic battle to control the very fate of the universe. Now, scientists are trying to shed light on the so-called “dark sector” as the latest generation of detectors rev up, and powerful telescopes peer deeper into space than ever before to observe how it behaves. Will the discoveries help reveal how galaxies formed? In the series finale, NOVA Wonders journeys to the stars and back to investigate what we know—and don’t know. Find out how scientists are discovering new secrets about the history of the universe, and why they’re predicting a shocking future.

The Brain that Changes Itself

Join us as we explore the revolutionary science of "neuroplasticity" - a concept that expands not just our knowledge of how our brains work, but how we use them. For centuries the human brain has been thought of as incapable of fundamental change. People suffering from neurological defects, brain damage or strokes were usually written-off as hopeless cases. But recent and continuing research into the human brain is radically changing how we look at the potential for neurological recovery. The human brain, as we are now quickly learning, has a remarkable ability to change itself - in fact, even to rewire itself. The Brain that Changes Itself, based on the best-selling book by Toronto psychiatrist and researcher Dr. Norman Doidge, presents a strong case for reconsidering how we view the human mind.

ADHD and Me: With Rory Bremner

Comedian and impressionist Rory Bremner is on a personal mission to uncover the science of ADHD (attention deficit hyperactivity disorder), a condition which he has suspected he has. In this film, Rory learns about the science of ADHD, goes for a diagnosis and tries the drug methylphenidate (also known as Ritalin) for the first time - just before walking on stage. Around three per cent of the adult population suffer from ADHD (and five per cent of children), yet many people remain sceptical of its existence, blaming it on naughty children or bad parenting.

The Myth of Responsibility

Are we wholly responsible for our actions? We don’t choose our brains, our genetic inheritance, our circumstances, our milieu – so how much control do we really have over our lives? Philosopher Raoul Martinez argues that no one is truly blameworthy. Our most visionary scientists, psychologists and philosophers have agreed that we have far less free will than we think, and yet most of society’s systems are structured around the opposite principle – that we are all on a level playing field, and we all get what we deserve.

Memory Hackers

Memory is the glue that binds our mental lives. Without it, we’d be prisoners of the present, unable to use the lessons of the past to change our future. From our first kiss to where we put our keys, memory represents who we are and how we learn and navigate the world. But how does it work? Neuroscientists using cutting-edge techniques are exploring the precise molecular mechanisms of memory. By studying a range of individuals ranging—from an 11-year-old whiz-kid who remembers every detail of his life to a woman who had memories implanted—scientists have uncovered a provocative idea. For much of human history, memory has been seen as a tape recorder that faithfully registers information and replays intact. But now, researchers are discovering that memory is far more malleable, always being written and rewritten, not just by us but by others. We are discovering the precise mechanisms that can explain and even control our memories. The question is—are we ready?

Me & My New Brain

Charlie Elmore suffered a brain injury in a snowboarding accident four years ago. Now she's going to retrace the steps of her dramatic recovery and meet other young people adjusting to life after serious brain injuries, including 19-year-old car-crash survivor Callum, avid skier Tai and fashion buyer Hannah, who has to re-learn how to walk and talk after she collapsed whilst out shopping and hit her head on the pavement. With their help, Charlie embarks on a courageous journey to improve understanding of this 'invisible' disability, which is the biggest cause of acquired disability in young adults in Britain, and discovers the hidden ways it affects her own life too.
