What strange forces saved one isolated section along the Upper Mississippi River from the repeated crushing and scouring effects of glaciers during the last two million years? And what pre-Ice Age throwbacks survived here in this unique geologic refuge that holds more Native American effigy mounds, petroglyph caves, strange geological features, and rare species than anywhere in the Midwest? These questions and more are answered in this captivating new documentary. A team of scientists embarks on a journey of exploration to expose both the science and threats behind three unique features of the zone - rare plants and animals, odd geological phenomenon, and striking remnants of a Native American pilgrimage like no other.
The biggest tech revolution of the 21st century isn’t digital, it’s biological. A breakthrough called CRISPR gives us unprecedented control over the basic building blocks of life. It opens the door to curing disease, reshaping the biosphere, and designing our own children. This documentary is a provocative exploration of CRISPR’s far-reaching implications, through the eyes of the scientists who discovered it, the families it’s affecting, and the genetic engineers who are testing its limits.
Travel alongside the astronauts as they deploy and repair the Hubble Space Telescope, soar above Venus and Mars, and find proof of new planets and the possibility of other life forming around distant stars.
In The Womb is a 2005 National Geographic Channel documentary that focus on studying and showing the development of the embryo in the uterus. The show makes extensive use of Computer-generated imagery to recreate the real stages of the process.
Darwin's great insight – that life has evolved over millions of years by natural selection – has been the cornerstone of all David Attenborough’s natural history series. In this documentary, he takes us on a deeply personal journey which reflects his own life and the way he came to understand Darwin’s theory.
A breathtaking adventure across five continents and through time to reveal nature's most vital secret. Watch a flying fox gorge itself on a midnight snack of figs. Climb into the prickly jaws of insect-eating plants. Witness a mantis disguised as a flower petal lure its prey to doom.
From the unique vantage point of 200 miles above Earth's surface, we see how natural forces - volcanoes, earthquakes and hurricanes - affect our world, and how a powerful new force - humankind - has begun to alter the face of the planet. From Amazon rain forests to Serengeti grasslands, Blue Planet inspires a new appreciation of life on Earth, our only home.
Many geneticists and archaeologists have long surmised that human life began in Africa. Dr. Spencer Wells, one of a group of scientists studying the origin of human life, offers evidence and theories to support such a thesis in this PBS special. He claims that Africa was populated by only a few thousand people that some deserted their homeland in a conquest that has resulted in global domination.
A documentary of insect life in meadows and ponds, using incredible close-ups, slow motion, and time-lapse photography. It includes bees collecting nectar, ladybugs eating mites, snails mating, spiders wrapping their catch, a scarab beetle relentlessly pushing its ball of dung uphill, endless lines of caterpillars, an underwater spider creating an air bubble to live in, and a mosquito hatching.
In 1858 Charles Darwin struggles to publish one of the most controversial scientific theories ever conceived, while he and his wife Emma confront family tragedy.
For Millions of years, our planet has been floating in space. Millions of creatures have lived on its surface. Many a quaint being was among them, but they affected only our, human imagination, for in the evolutionary struggle we are the only ones who have obtained the advantage of reason.
When Harvard PhD student Jennifer Brea is struck down at 28 by a fever that leaves her bedridden, doctors tell her it’s "all in her head." Determined to live, she sets out on a virtual journey to document her story—and four other families' stories—fighting a disease medicine forgot.
The film is filled with fun facts that show how cats make good pets, yet in other ways are wild and untamable.
David Attenborough takes us on a guided tour through the secret world of plants, to see things no unaided eye could witness. Each episode in this six-part series focuses on one of the critical stages through which every plant must pass if it is to survive:- travelling, growing, and flowering; struggling with one another; creating alliances with other organisms both plant and animal; and evolving complex ways of surviving in the earth's most ferociously hostile environments.
What if there was a museum that contained every type of life form in the universe? This experience takes you on a tour through the possible forms alien life might take, from the eerily familiar to the utterly exotic, ranging from the inside of the Earth to the most hostile corners of the universe. New research is upending our idea of life and where it could be hiding: not just on Earth-like planets, where beings could mimic what our planet has produced, but in far flung places like the hearts of dead stars and the rings of gas giant planets. Nowhere in the universe is off limits. Only when we know what else is out there will we truly know ourselves. This thought experiment will give us a glimpse into what could be out there, how we might find it, and just how far nature’s imagination might stretch.
Short film about the movement patterns of protozoa
A documentary that explores the natural world of the sea, from the single-celled organism to more complex forms of life, OCEAN ORIGINS was originally filmed in the IMAX large format, which adds a crispness and clarity to the images. This documentary film seeks to examine the process of evolution by looking at the many creatures of the sea that can illustrate the way multi-cellular life emerged over the course of four billion years. OCEAN ORIGINS is a creative film that uses fascinating documentary footage to look at scientific theories and principles in an interesting manner
