NOVA: Episode 10
Tóm tắt
During World War I, the Allies and Germans repeatedly struggled to break the hideous stalemate of trench warfare. In the winter of 1916, Allied engineers devised a massive surprise attack: over 1 million pounds of explosives hidden in secret tunnels driven under German lines. Building the tunnels was desperate work, with tunnelers at constant risk from flooding, cave-ins, and enemy digging teams. In June of 1917, the planted mines at Messines were simultaneously triggered, killing an estimated 10,000 German troops instantly. Now, archaeologists are revealing the extraordinary scale and risks of the Allied tunneling operations in one of the biggest excavations ever undertaken on the Western Front. “Secret Tunnel Warfare” opens a unique window on the frenzy of Allied mining activity that led up to the attack and its bitter aftermath.

Tập 9
On November 25th, 1915, Einstein published his greatest work: general relativity. The theory transformed our understanding of nature’s laws and the entire history of the cosmos, reaching back to the origin of time itself. Now, in celebration of the 100th anniversary of Einstein’s achievement, NOVA tells the inside story of Einstein’s masterpiece. The story begins with the intuitive thought experiments that set Einstein off on his quest and traces the revolution in cosmology that is still playing out in today’s labs and observatories. Discover the simple but powerful ideas at the heart of relativity, illuminating the theory—and Einstein’s brilliance—as never before. From the first spark of an idea to the discovery of the expanding universe, the Big Bang, black holes, and dark energy, NOVA uncovers the inspired insights and brilliant breakthroughs of “the perfect theory.”
Tập 11
Four and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged. But how? NOVA joins mineralogist Robert Hazen as he journeys around the globe. From an ancient Moroccan market to the Australian Outback, he advances a startling and counterintuitive idea—that the rocks beneath our feet were not only essential to jump-starting life, but that microbial life helped give birth to hundreds of minerals we know and depend on today. It's a theory of the co-evolution of Earth and life that is reshaping the grand-narrative of our planet’s story.

The history of North America since the arrival of humans is chronicled. Natural resources, including gold and oil, have enabled humans to transform the land almost as much as the geological forces that created it. However, geology may, some day, play another role in reshaping the continent: the Cascadia fault line in the Pacific Northwest could unleash a massive earthquake and tsunami; and the super-volcano beneath Yellowstone could obliterate half the continent if it erupts.
Tập 12
Tiny, transparent, and threatened, krill are crucial to the Antarctic ecosystem. But the population of krill is crashing for reasons that continue to baffle the experts. A leading theory says that krill’s life cycle is driven by an internal body clock that responds to the waxing and waning of the Antarctic ice pack, and as climate change alters the timing of the ice pack, their life cycle is disrupted. To test it, NOVA travels on the Polarstern, a state-of-the-art research vessel, to the frigid ice pack in the dead of winter. From camps established on the ice, scientists dive beneath the surface in search of the ice caves that shelter juvenile krill during the winter. There, they hope to discover what’s causing the krill to vanish and, ultimately, how the shifting seasons caused by climate change could disrupt ecosystems around the world.
Tập 7
How did life emerge on our primeval continent? Why was North America home to so many iconic dinosaurs like T. rex? And how did a huge sea filled with giant marine reptiles end up covering Kansas? We tell the surprising intertwined story of life and the landscape in North America.
Tập 13
On April 25, 2015, a devastating earthquake rocked Nepal. As it ripped across the Himalayas, it wiped out villages and left thousands dead. Hear the harrowing stories of the Nepalese people who lived near the epicenter and of survivors trapped on Everest. Through dramatic eyewitness footage, expert interviews, and stunning graphics, NOVA reveals the anatomy of this megaquake while scientists race to answer urgent questions—Is another big one just around the corner? What can we learn from the deadly combination of earthquakes and landslides? And can we rebuild to survive the next big one?
Tập 6
The epic 3 billion-year story of how our continent came to be. From the palm trees that once flourished in Alaska to titanic eruptions that nearly tore the Midwest in two, discover how forces of almost unimaginable power gave birth to North America.
Tập 14
On a summer’s night, there’s nothing more magic than watching the soft glow of fireflies switching on and off. Few other life forms on land can light up the night, but in the dark depths of the oceans, it’s a different story: nearly 90% of all species shine from within. Whether it’s to scare off predators, fish for prey, or lure a mate, the language of light is everywhere in the ocean depths, and scientists are finally starting to decode it. NOVA and National Geographic take a dazzling dive to this hidden undersea world where most creatures flash, sparkle, shimmer, or simply glow. Join deep sea scientists who investigate these stunning displays and discover surprising ways to harness nature’s light—from tracking cancer cells to detecting pollution, lighting up cities, and even illuminating the inner workings of our brains.
Tập 5
NOVA joins a team of leading Egyptologists who deploy the latest medical imaging to peer beneath the wrappings of Egyptian mummified beasts without damaging the animal bodies inside. The results are enlightening, often surprising insights into the weird beliefs and practices that clung to the Egyptian quest for immortality.
Tập 15
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?
Tập 4
NOVA examines the science and technology behind cyber warfare and asks if we are already in the midst of a deadly new arms race.
Tập 16
He was stalked, attacked and left to die alone. Murdered more than 5,000 years ago, Otzi the Iceman is Europe’s oldest known natural mummy. Miraculously preserved in glacial ice, his remarkably intact remains continue to provide scientists, historians, and archeologists with groundbreaking discoveries about a crucial time in human history. But in order to protect him from contamination, this extraordinary body has been locked away, out of reach, in a frozen crypt—until now. NOVA joins renowned artist and paleo-sculptor Gary Staab as he has been granted rare access into the Iceman’s frozen lair. Gary has been charged with creating an exact replica of the mummy, which scientists and the public alike can then study up close and in person. As we see the Iceman reborn from 3D printing, resin, clay and paint, new revelations about Otzi’s life and legacy come to light, including surprising secrets hidden in his genetic code.
