NOVA presents "Arctic Ghost Ship" an exclusive breakthrough in the greatest unsolved mystery in Arctic exploration. In 1845, British explorer Sir John Franklin set off to chart the elusive Northwest Passage, commanding 128 men in two robust and well-stocked Royal Navy ships, the Erebus and Terror. They were never heard from again. Eventually, searchers found tantalising clues to their fate: a hastily written note left on an island, exhumed bodies suggesting lead poisoning, discarded human bones with marks of cannibalism and Inuit legends of ghost ships. But no trace of the ships was ever found. Then, in 2014, after seven years of searching, an official Parks Canada expedition finally located the Erebus, intact and upright on the sea floor. With exclusive access, NOVA tells the inside story of the risky Canadian expedition, which involved constant battles with crushing sea ice, bad weather, and disappointing dead ends. Culminating in the historic discovery of the Erebus, NOVA tells the gripping story of the ill-fated expedition and reveals exclusive new clues from the sea floor that may finally unravel what happened to Franklin's men more than 160 years ago.

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.
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?
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.

Growing desperate in 1943, Hitler hatches a diabolical weapon: a bank of "superguns" housed in a massive underground complex in Nazi-occupied northern France. Together the guns would be able to pump 600 high explosive shells 100 miles into downtown London every hour. This weapon could spell doom for the allies. But how can such a massive gun possibly work? Join NOVA as engineers, archaeologists and WWII historians investigate this fearsome weapon. And discover the two audacious missions designed to destroy the seemingly impregnable supergun complex, one of which is led by Joseph Kennedy, Jr.
