Clouds continue to drift by.

An ejaculate of sperm swim through a uterus. At the branches of the Fallopian tubes, half go one way and half the other. Down one tube toward the sperm bounces a female head, singing, happily on her way. Four sperm zero in; she panics but can't avoid them. Pow! they hit her full force and disappear into her. The decision she makes and what she does next change the course of her life in a major way.

A documentary that looks at systemic sexism faced by women scientists in STEM fields.

A psychedelic documentary of the body electric, with music by Pink Floyd. The film was directed and produced by Roy Battersby.

Acoustic Ocean is an artistic exploration of the sonic ecology of marine life in the North Atlantic. Located on the Lofoten Islands in Northern Norway, the video centers on the performance of a marine-biologist diver who is using a life-size model of a submersible equipped with all sorts of hydrophones and recording devices. In this science-fictional quest, her task is to sense the submarine space for acoustic and bioluminescent forms of expression.

Leonardo da Vinci is not just the most famous and most admired of all painters - he is an icon, a superstar. Yet, the man himself remains elusive. Accounts during his lifetime describe a man too handsome, too strong, too perfect to be accurate. But in 2009, the chance discovery in the South of Italy of an ancient portrait with strangely familiar features takes the art world by storm. Could this be an unknown self-portrait by Leonardo da Vinci? Controversy erupts among the experts. The implications of such a discovery have far-reaching consequences for our understanding of the work of this great Renaissance master.

As new parents can attest, children develop so much in the first year of their life it's hard to keep up. From the moment they draw their initial breath - itself an incredibly complicated biological feat - to their first steps, it's a year of remarkable development. In The Science of Babies, Nat Geo explores the amazing biomechanical benchmarks achieved in the first 12 months of human life. Using CGI, fMRI and other tools, viewers can watch as a baby's lungs draw breath for the first time, and can witness the heart grow exponentially in order to power this incredible developing creature. Perhaps even more fascinating is the manner in which the neurosynapses develop, creating the essence of what will become a new personality and intellect. This film explores the amazing mechanics behind the initial milestones in a human infant's life, and even compares them to babies of other species.

This film reveals the exquisite machinery of the human cell system from within the inner world of the cell itself - from the frenetic membrane surface that acts as a security system for everything passing in and out of the cell, the dynamic highways that transport cargo across the cell and the remarkable turbines that power the whole cellular world to the amazing nucleus housing DNA and the construction of thousands of different proteins all with unique tasks. The virus intends to commandeer this system to one selfish end: to make more viruses. And they will stop at nothing to achieve their goal.

Das kreative Universum

Using spectacular graphics based on the latest science and stories of remarkable people around the world, Michael Mosley takes us on a fantastic voyage through our inner universe.

This is an unknown world. Yet it seems strangely familiar: Deep canyons and cracks scar the landscape, imposing mountain ranges tower over scorched plains, moist jungles and acidic lakes hide creatures unknown to most – ferocious predators, grazing vegetarians, cunning quick-change artists. But this alien planet is not from outer space. This planet is you.

Over three very personal films, Sir David Attenborough looks back at the unparalleled changes in natural history that he has witnessed during his 60-year career.

This documentary exposes the massive public health dangers of genetically modified organisms (GMOs). The film features the world's leading scientists, physicians, professors, politicians, attorneys, and environmental activists who reveal the frightening truth surrounding the vast use of GMOs in our food supply. You'll see the deception and deep layers of corruption being perpetuated against the public at large by the world's largest and most powerful biotechnology companies, chemical companies, agricultural companies, and governments.

Geologist Ian Stewart explain in three stages of natural history the crucial interaction of our very planet's physiology and its unique wildlife. Biological evolution is largely driven bu adaptation to conditions such as climate, soil and irrigation, but biotopes were also shaped by wildlife changing earth's surface and climate significantly, even disregarding human activity.

A documentary about the study of plant sentience with original music by Stevie Wonder. Utilizing time-lapse photography, the film proposes that plants are able to experience emotions and communicate with the world around them.

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.
