Filmed over two years in a remote part of the Canada. Cameras observe a young female grizzly as she grows into adulthood. Filmed over two years, the documentary features vistas of open plains on the Arctic Circle and frigid rivers in vast mountain ranges. Against the backdrop of the vast Yukon tundra, the climate changes from frigid winter to spring thaw with a brief sunny season in-between. The cast of characters features hulking male grizzlies, mothers and cubs socialising until the salmon runs begin. Female bears must consume enough salmon during this brief time in order to sustain the cubs that will be born during the winter.

Mars has beckoned humankind for centuries, but only in the last 50 years have we begun to scratch its surface. The latest Martian explorer is Perseverance, an uber-sophisticated rover, chock-full of scientific instruments, including 23 cameras, a robotic arm, lasers, and spectrometers, designed to analyze the terrain and reveal if there was ever life on the Red Planet. Join us as we examine the latest rocket, rover, and interplanetary helicopter.

How is the universe put together? How is it built? And how does it actually work? Learn how nuclear fusion keeps them burning for billions of years and what powers our nearest star: the Sun. in Part 3 NASA's Parker Solar Probe investigates our Sun.
Chris looks at social intelligence in the animal kingdom and finds out why it is that, for animals, being together means being clever. He looks at how lions hunt in teams and each hold a very specific position, how vampire bats build trust and donor networks through grooming, and how wild wolves first became domesticated and transformed into man's best friend.
Finding somewhere to keep safe is one of the biggest challenges an animal faces. But some animals don't have to find a safe place - they build one. Chris reveals some of the best building animals in the world - a group that is incredibly varied. Accomplished animal architects include everything from beavers to bees and prairie dogs to bowerbirds. They don't only build homes, however - they also make structures to raise their young, store food, catch prey and impress mates. But what can be learnt from their building brilliance?
Chris reveals some of the cleverest animal communicators on the planet. For decades, people have longed to emulate Dr Doolittle and be able to understand what animals are communicating to one another. But their methods often go far beyond the capabilities of our human senses. Now, thanks to dedicated researchers, new science and cutting-edge technology, we're being given a glimpse into the ingenious ways that animals get their message across - that dolphins have individual names for each other, that cuttlefish use covert signals, and that humans can understand apes without even realising it.
Chris investigates how nature's masterminds measure up against human brain power. Looking at a variety of animals, such as ravens, crows, bees and starlings, Chris explores how different animals can use tools, solve complex puzzles, recognise themselves in mirrors and even reason like humans.
Stephen Fry and the zoologist Mark Carwardine follow attempts to move the world's rarest rhinos from a snowy zoo in the Czech Republic, to the expanses of Kenya in the hope that they will breed in the wild. With only eight of these creatures left on earth, the mission becomes a race against time to save the Northern White Rhino from extinction.
As the expedition team near the end of their journey across Micronesia, it's a race against time for the extreme deep divers as they continue their search for new species. As Kate Humble explores the Rock Islands of Palau, Mike DeGruy embarks on a unique training programme. The Newtsuit is an incredible feat of submarine engineering - a bright yellow one-man submersible that Mike has to master before he can venture even deeper into the Pacific abyss.
Off the coast of Micronesia, Kate Humble and her scuba team continue to discover spectacular examples of underwater life. Meanwhile, the deep-sea divers search for previously unseen fish in depths that test the limits of human endurance, but their explorations are hindered by an unexpected equipment failure.
See the extraordinary wildlife and people of the Andes. Pumas hunt guanaco, shape-shifting frogs hide in remote cloud forests and the descendants of Inca build bridges of grass. The world’s driest desert, huge salt lakes and spectacular peaks are all found in the world’s longest mountain range.
Tour the extraordinary wildlife and people of the Himalaya – the highest mountain range on earth. Bizarre snub-nosed monkeys live in frozen forests. Tibetan monks perform ancient rituals high in the mountains whilst snow leopards prowl the mountain sides.
The Rockies stretch 3,000 miles up the length of North America, and are one of the great mountain ranges of the world. These mountains are home not just to cougars, wolverines, wolves, and grizzly bears, but also daredevil wingsuit flyers, which jump from high peaks, and Native Americans, competing in breakneck horse races.
On a high ridge in Newfoundland, Canada, nestled between the Atlantic Ocean and the borders of an old grove forest, a Red fox, the matron of her family group, gives birth yet again. Follow the pups as they grow and learn to hunt, adapt, and survive. Explore the family dynamic of these clever creatures as bonds are formed. But the vixen knows that not all her cubs will inherit these tall trees, crystal lakes, and the ocean spray. Before the snows come again, she will have to banish some of her offspring for the good of the family. We also hear from scientists in Madison, Wisconsin and Bristol, England, about their studies on urban Red foxes who are facing a much different challenge than their Canadian counterparts. And another scientist tracks how Red foxes are moving out to the Arctic tundra and surviving in one of the harshest landscapes.
Discover the secrets of humanity’s advanced skill set and predominance on earth. It was the rapid growth of our brain, originating about 2 million years ago, that allowed us to be the predominant species of the world. What caused this rapid growth of our cerebral cortex?

Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste. Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mindboggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.
