Eat less, move more. That’s been the mantra of the weight loss movement for decades. But as those who have fought the battle of the bulge will tell you, there’s a lot more to obesity than just too much junk food or too little willpower.
For thousands of years, we’ve regarded sleep as nothing more than an annihilation of consciousness. But there is one compelling fact that has always stood in the way of that view. “Even the Greek philosophers wondered why we needed to sleep,” says neuroscientist, Dr. Kenneth Wright. “If sleep wasn’t important, it’s probably one of the most significant mistakes that evolution ever made.” Yet decades of intense research have failed to discover the key function of sleep. But now, thanks to revolutionary new technology, innovative animal research and extraordinary advances in genetics, all that’s about to change. Join Dr. Jennifer Gardy as she goes on an extraordinary odyssey from a city that never sleeps to an isolation chamber in the Colorado Rockies, from one of the most unique research centres in the world to the world of dreams. Her goal is simple: Discover why we sleep

Lyme disease, a mysterious tick-borne illness, is the fastest spreading vector-borne disease in the United States, and over the past decade, the tick that carries Lyme has been spreading across Canada with alarming speed. Ticked Off: The Mystery of Lyme Disease, is a fascinating and eye-opening documentary that explores a disease that has devastating effects, is often misdiagnosed and mistreated, and continues to be mired in a medical controversy. More than 30,000 cases are reported in the USA every year, but the real number could be as high as 300,000. And despite hard evidence that the Lyme-carrying, deer tick has already established populations across Canada, some people claim that patients here are still being told that they cannot contract Lyme in this country. Doctors agree that if it’s caught early Lyme disease can usually be cured with two to four weeks of antibiotics. There are others who believe that if it’s not caught early, the infection can develop into a debilitating condition they call Chronic Lyme. Yet unlike West Nile, Encephalitis or SARS, where the medical profession and scientists joined forces to find better treatments or a cure, many patients, who claim to have chronic Lyme, say that they are being denied treatment and left to suffer. So why is this happening?

Untangling Alzheimer's is a dramatic and inspiring medical investigation driven by David Suzuki's journey to understand the science of Alzheimer's and the surprising new insights into its cause. David has a very personal interest in the disease because his mother, aunt and two uncles died of it. We join David on an intimate journey as he explores the newest breakthroughs in this devastating disease as well as his own chances of contracting the cruel condition. Alzheimer's today is the only leading cause of death that cannot be cured, prevented or even slowed. Worse, it's the only leading cause of death that is on the rise – and not simply because baby-boomers are getting older. Studies show that the increase is absolute across all age groups, and death rates continue to climb. With a new case developing every 69 seconds, scientists now speak of the Alzheimer's epidemic.

Where Am I? Is a new documentary about the skills we use to find our way around. Whether you are an Inuit hunter, a foraging insect, or just someone out for a stroll, your brain is performing one of its most fundamental services – it’s navigating. Why are some of us good at finding our way, while others are not? Good navigators are able to use both memory and imagination…remembering where they have been, and imagining where they’re going. Some researchers believe we build a cognitive or mental map when we navigate, a kind of bird’s eye view of our surroundings, a view that can be rotated and examined in our mind. There has been about sixty years of argument amongst scientists about whether humans and other mammals actually form these cognitive maps or not. The advent of GPS or Global Positioning Systems has changed the discussion about navigation. GPS triggers a simpler, more automatic navigational technique that does not involve building a mental map. With GPS, we simply respond to directions and may not truly understand where we are.

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.

Supermarkets are stocked with fruit year round in a global permanent summertime, but despite its accessibility, have we lost the diversity that makes it so special? The second episode of The Fruit Hunters will look at what happens when we abandon the Garden of Eden for an industrialized monoculture. In lush jungles of Borneo, Bala Tingang, an elder of one of the last hunter-gatherer tribes, lives of the wild fruits that are the key to his tribe's survival. And yet, all around the world, natural diversity is being replaced with monocultures, plantations of only one variety, bred for long shelf life and transportability rather than their taste or health properties. Not only is this lost of diversity impoverishing our taste buds, but it has catastrophic implications for our food security. In the vast uniform banana fields of Honduras, Juan Aguilar, a banana scientist, frantically tries to breed a banana resistant to a deadly fungus.

We like to believe we’re in control. But if what we’re discovering about parasites is anything to go by, who is really in control is a lot more complicated, and a lot more interesting, than we ever imagined. So let “The Nature of Things with David Suzuki” help you get over the ick factor, and explore the world of parasites. So let “The Nature of Things with David Suzuki” help you get over the ick factor, and explore the world of parasites. Scientists have collected hundreds of examples of parasites that brainwash their hosts. And now researchers are starting to untangle these parasites’ evolutionary tricks of the trade. In the coastal estuaries of California, Professor Kevin Lafferty of the United States Geological Survey introduces us to a flatworm that lives in three hosts - a snail, a fish and a bird. This parasite’s influence is so profound that it tips the balance of the local ecosystem

Are gay men actually born gay? If so, what causes this and how could homosexuality have survived the evolutionary process? Ever since openly gay filmmaker Bryce Sage came out of the closet, he has struggled to answer these fundamental questions. Bryce sets out on a cross-country and around the world journey to ferret out the answers. Along the way, he confronts his own homosexuality and family history, exploring the nature vs. nurture side of the issue. He’ll bombard his brainwaves with gay and straight erotica to determine just how fundamentally gay his brain really is and he’ll talk to animal biologists about their studies of homosexuality in other species. There is documented evidence of homosexuality in over two hundred. Bryce becomes an amateur detective, trying to crack the code of his genes. He discovers that in Samoa every family has a male member who is either gay or is encouraged to become more feminine to support familial needs.

This episode focuses on the Asia-Pacific side of The Pacific Rim of Fire, which stands as a living testament to the beauty and danger that powerful geologic forces can deliver. The Pacific Rim is home to half of the world's active volcanoes and ninety percent of the world's earthquakes, yet nearly 800 million people continue to live within its violent edge. Our journey begins in New Zealand, a land of volcanoes and earthquakes, where we find a 500-kilometre long slip-strike fault deep under the Pacific Ocean. Geologist Hamish Campbell will take us to the crater of White Island, the country’s most active volcano. Then we'll visit the country's southern island with John Youngson, to find out how New Zealand’s longest fault-line contributes to the gold industry. Finally in Japan, viewers will hike up to Mount Fuji – the iconic peak where science and legend converge, getting up-close and personal with a fault-line witnessing firsthand what it’s like to discover new ways of monitoring, and hopefully one day predicting, seismic activity onboard the world’s most advanced drilling vessels.

A fresh perspective on autism research with the developing "Bacterial Theory" of autism. The fastest-growing developmental disorder in the industrialized world, autism has increased an astounding 600 per cent over the last 20 years. Science cannot say why. Some say it's triggered by environmental factors and point to another intriguing statistic: 70 per cent of kids with autism also have severe gastrointestinal symptoms. Could autism actually begin in the gut? The Autism Enigma looks at the progress of an international group of scientists who are studying the gut's amazingly diverse and powerful microbial ecosystem for clues to the baffling disorder.

In the heart of a metropolitan city of 15 million people and among the construction of a new billion-dollar transportation network, an archaeological sensation has been discovered: the ancient harbour of Theodosious. Theodosious was the last ruler over both Eastern and Western portions of a unified Roman Empire; the harbour has been buried and shrouded in mystery for over 800 years…until now. Istanbul, Turkey, is situated exactly between Europe and Asia. It has, since prehistoric times, bridged the gap between these continents, their cultures and its people. Engineers are working to connect East to West through a spectacular 1.4 kilometer railway tunnel, 60 meters below the surface, but they've been stalled by the discovery of the Emperor's Lost Harbor.
