The world's coastal regions have always been an extreme environment to raise a family, but warming seas are exacerbating the challenges of parenthood. A hurricane hits a flamingo colony while chicks are still on the nest, a sea otter faces a huge winter storm in California, a clownfish on the Great Barrier Reef sees its anemone home bleached, and a little anole lizard clings on during a hurricane.

Horizon investigates a new era of Alzheimer's research, which is bringing hope to millions of sufferers across the world. New scanning and gene technology is allowing scientists to identify the disease at its earliest stages, often 15 years before symptoms appear and the brain cells are destroyed. A series of new drugs trials in Colombia, the USA and Europe are showing startling success in reducing beta amyloid, the protein which is a hallmark of the disease. It is also becoming clear that changes in lifestyle can prevent the development of the disease. A new system inside the brain has been discovered which clears amyloid when we are in deep sleep, but allows it to accumulate if we don't sleep well. The programme reveals that for sufferers in the early stages of the disease, brain connections, or synapses, can be strengthened and even replaced by absorbing enough of the right nutrients. A UK-wide trail helps sufferers in the early stages to concentrate on improving everyday tasks, and in the process not only make their lives easier, but helps to reactivate the planning and organisational parts of the brain. In an ageing world, where the biggest risk of developing Alzheimer's is old age, the scientific breakthroughs in Alzheimer's disease are bringing hope where once there was despair.
There are so many unanswered questions about the stars, the galaxies, and the universe and just mapping what lies in the night sky is immensely difficult. This episode looks at the effort involved in making the first photograph of a black hole and the search for planets orbiting distant stars.

Our ancient human ancestors once lived only in Africa, in tiny bands of a few thousand hunter-gatherers. Then we moved out of our African cradle, spreading rapidly to every corner of the planet. How did we acquire the skills, technology and talent to thrive in every environment on earth? How did our prehistoric forebears cross the Sahara on foot, survive frigid ice ages, and sail to remote Pacific islands? “Great Human Odyssey” is a spectacular global journey following their footsteps out of Africa along a trail of fresh scientific clues. With unique glimpses of today’s Kalahari hunters, Siberian reindeer herders, and Polynesian navigators, we discover amazing skills that hint at how our ancestors survived and prospered long ago.
Professor Alice Roberts explores the story of human evolution, revealing how a humble African ape became a successful global species. With daring parkour athletes and life-size primate animatronics, Alice explores the greatest leaps in our evolution by conjuring fire and re-enacting how we spread across the globe.

Some 30 million Americans have sent their DNA to be analyzed by companies like 23andMe and AncestryDNA. But what happens once the sample is in the hands of testing companies, and how accurate are their results? NOVA explores the power of genetic data to reveal family connections, ancestry, and health risks—and even solve criminal cold cases.
Do you make your own luck or does luck make you? We find luck, good and bad, in casinos, basketball courts, genetics labs and the subatomic world. It's a journey that will radically revise your understanding of the laws of nature and the human brain.

Saiful investigates how to generate energy without destroying the planet in the process. Saiful begins his lecture by being plunged into darkness. Armed initially with nothing but a single candle, his challenge is to go back to first principles and bring back the power in the energy-hungry lecture theatre. Along the way he explains what energy is, how we can transform it from one form to another, and how we harness it to power the modern world. A fascinating and stimulating celebration of the stuff that quite literally makes the universe tick - the weird and wonderful world of energy.

In the vast Canadian wilderness, there lives a very special bear family. Just out of hibernation, two black cubs have a pure white mother. She's not a polar bear or albino - locally she's known as a ghost bear. This far north, winter is never far away, and this unusual family must work hard to find enough food to see them through. They will also need to avoid other large predators, but being so different could bring them unwelcome attention.

Why are ultra-processed foods so irresistible, and how they have come to dominate food culture? Dr Chris van Tulleken features interviews with former food industry insiders who talk openly about the way in which popular foods have been designed to be irresistible. Food companies go to extraordinary lengths to ensure their products connect with consumers - from using brain scans to assess the deliciousness of ice cream to carefully engineering the sound of a crunch. Ultra-processed foods are hyper-delicious and super-convenient, have long shelf lives and are extremely cheap. But a growing body of evidence is linking these products to our declining health.

Day by day. Hour by hour. Second by second. This is the story of last century's bloodiest conflict told in a concise and compelling 3 hour special. Including personal accounts, strategic analysis and rare footage, Inside WWII provides a new and intimate perspective on the experience of war. A soldier's duty is not to reason why; a soldier's duty is to do or die. Inside World War II is the story of the doing and the dying … in the defining conflict of the 20th century. From the producers of the critically acclaimed specials Inside 9/11 and Inside the Vietnam War comes a three-hour television event that provides a detailed visual timeline of this complex war, with personal, in-depth stories from veterans who fought in one of the deadliest conflicts in human history. Inside World War II combines archival footage with more than 50 testimonies from American, British, German and Soviet servicemen; a former member of the Hitler Youth; and Jewish and black Germans who endured persecution under Hitler's reign. Viewers hear from America's first Japanese American senator, Daniel Inouye, in one of his final interviews before passing away, as he describes with haunting candor what it was like to kill someone during battle. "He had on this German hat, so I told the men, 'That's mine.' He was not only my first, but when I think back, I think back with horror because I was proud." Inouye, a Medal of Honor recipient for his service in World War II, goes on to say, "You don't forget the horrors of the war." The explosive first hour of Inside World War II begins in pre-war Germany at the 1936 Olympics, with American distance runner Louis Zamperini describing in an original, never-before-seen interview what it was like to meet Adolf Hitler. "His face, his mustache, the way he combed his hair. I mean he looked like somebody purposely did cosmetics on him for a comedy. He was, to us, a dangerous comedian." The second hour explores the attitudes of soldiers fresh from battle, including Harold Brown, an original Tuskegee Airman who recalls what it was like to fly next to and protect long-range bombers, and Paratrooper Earl McClung, who shares a harrowing tale of being stranded behind enemy lines. Author Benjamin Patton also explains how his grandfather General Patton commanded a ghost army to mislead the enemy, "He was commanding a fictitious Army group that was made up of inflatable tanks and cardboard vehicles, and tents," while General Eisenhower stormed the beaches of Normandy. Inside World War II culminates with the dramatic events of 1945, from Hitler's suicide to the revelation of Nazi concentration camps. And we'll hear Col. Paul Tibbets address the media after dropping the world's first wartime atomic bomb: "We saw this cloud of boiling dust and debris below us with this tremendous mushroom on top. Beneath that was hidden the ruins of the city of Hiroshima." As Lt. Lynn "Buck" Compton, 101st Airborne, US Army (Ret.), in the last interview he gave before his death last year, concludes, "I'm glad I did it. I wouldn't trade it for anything. Not that it was fun, but I think of it as it's a part of my life. And just lucky that I lived through it."
