Cuba’s diverse wildlife stems from its unique natural history. Cuba was not originally in the Caribbean Sea but in the Pacific Ocean, where the island was situated 100 million years ago, before the forces of continental drift slowly brought it into the Caribbean. As the island migrated over the ages, an astonishing variety of life arrived by air, sea, and possibly by land bridges that may have once existed. Over time, these animals adapted to their new environment. Today, more than half of Cuba’s plants and animals, including more than 80 percent of its reptiles and amphibians, are found nowhere else on the planet.

Protected by its isolation, the wildlife of Cuba has remained naturally preserved, untouched, and unexplored. Through a special arrangement with the Cuban government, unprecedented access was granted to film the island’s natural riches.

Join NATURE in exploring Cuba’s coral reefs, swamps, forests, and caves to uncover the astonishing diversity of life on the island.

We take for granted the technology of cold, yet it has enabled us to explore outer space and the inner depths of our brain, And, as we develop new ultracold technology to create quantum computers and high speed networks, it will change the way we work and interact.

How did we harness something once considered too fearsome to even investigate? How have scientists and dreamers, over the past four centuries, plunged lower and lower down the temperature scale to conquer the cold and reach its ultimate limit, a holy grail as elusive as the speed limit of light? Absolute Zero, up next on NOVA.

The word Himalaya is Sanskrit for “abode of snow” – fitting for a stretch of land that houses the world’s largest non-polar ice masses. Extensive glacial networks feed Asia’s major rivers including the Ganges, Indus, and Brahmaputra. More than a billion people rely on these glacier-fed water sources for drinking water and agriculture. The Himalayas are not only a remarkable expanse of natural beauty. They’re also crucial for our survival.

NATURE takes us on a stunning journey to the Himalayas. From Everest to the Tibetan Plateau, from the Gaumukh to the Ganges, this episode introduces us to a complex, interconnected natural world that continues to inspire, challenge and amaze the human race.
