On April 25, 1953, James Watson and Francis Crick published their groundbreaking discovery of the double helix structure of DNA. But their crucial breakthrough depended on the pioneering work of another biologist, Rosalind Franklin. 50 years later, NOVA investigates the shocking truth behind one of the greatest scientific discoveries and presents a moving portrait of a brilliant woman in an era of male-dominated science.

A documentary on Al Gore's campaign to make the issue of global warming a recognized problem worldwide.
This film consists of three parts. The first dramatizes the life of the founder of Soviet astronautics, Konstantin Tsiolkovsky; the second describes the development of rocket technology; and the third visualizes the future with enactments of the first manned spaceflight, spacewalk, space station construction and humans on the moon.
Sniper: Bulletproof deconstructs and analyzes the little-known sniper events that have occurred when no other course of action was possible. The people who planned the takedowns, or pulled the trigger, share their techniques and bring to light the many factors that had to be considered in each mission: terrain, wind speed, temperature, elevation changes... all are critical to taking out targets considered bulletproof. A sniper has one chance, one breath, to rise to the occasion and save the day... if they miss, there may never be another opportunity. As these never told before stories unfold, the viewer also learns about the high-tech gear each sniper carries on their classified missions.
Trees talk, know family ties and care for their young? Is this too fantastic to be true? German forester Peter Wohlleben and scientist Suzanne Simard have been observing and investigating the communication between trees over decades. And their findings are most astounding.
Unlocking the Mystery of Life represents a unique programming opportunity for local stations. Its broadcast release coincides with the 50th anniversary of one of the greatest scientific breakthroughs in history-James Watson and Francis Crick's discovery that the DNA molecule carries hereditary information in the form of a code that many scientists have likened to computer software or a written language. This discovery (announced on April 25,1953) sparked a scientific revolution. But it also left a fundamental question unanswered. Where did the information in DNA come from? How did the software in the cell arise? Unlocking the Mystery of Life explores these questions through the stories of a growing number of scientists who no longer believe that natural selection or chemistry, alone, can explain life's origin. Instead, they think that the microscopic world of the cell provides evidence of purpose and design in nature.
A documentary chronicling the history of the telescope from the time of Galileo. Featuring interviews with leading scientists discussing Galileo's first use of the telescope to the latest discoveries in cosmology.
For the past 20 years, the world has seen an alarming decrease in IQ and a rise of autism and behavioral disorders. This international scientific investigation reveals how chemicals in objects surrounding us affect our brain, and especially those of fetuses.
Take a fascinating journey inside the bizarre world of a living human being with this compelling documentary from National Geographic, where microscopic cameras and other state-of-the-art technologies reveal perspectives that will blow your mind. Tracking the body of a female from infancy to old age, viewers will observe the digestion of a meal, the development of the cardiac system and other mesmerizing aspects of the body's inner workings.
A young apprentice struggles to master nanotechnology on an alien world and prove herself to her enigmatic master. Will her herculean goals remain tantalizingly out of reach, or will she fulfill them and in the process, change life as we know it?
This documentary outlines the unique properties and latest studies of "Physarum Polycephalum", also known as Blob.
For a few years now, scientists have known about the existence of another brain within our bodies. This second brain, or "brain down below" is none other than our stomach. The stomach's intelligence is a new avenue of research that is fascinating research teams the world over.
An exploration of the link between science and beauty through the work of scientists at CERN, in Geneva.
Meet Nikola Tesla, the genius engineer and tireless inventor whose technology revolutionized the electrical age of the 20th century. Although eclipsed in fame by Edison and Marconi, it was Tesla's vision that paved the way for today's wireless world. His fertile but undisciplined imagination was the source of his genius but also his downfall, as the image of Tesla as a mad scientist came to overshadow his reputation as a brilliant innovator.
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
South western Pennsylvania area of colonial America, 1760s. Colonial distaste and disapproval of the British government is starting to surface. Many local colonists have been killed by American Indians who are armed with rifles supplied by white traders.
While life expectancy is increasing in Western countries, cases of diabetes, hypertension, obesity and cancer are increasing, and the use of medication has exploded. Does this mean that in order to live to a ripe age we are condemned to swallow more and more drugs? What if there was another way? For half a century, in Russia, Germany and the U.S., doctors and biologists have been exploring a different therapeutic approach: fasting. The results are amazing. Soviet researchers have provided a body of clinical studies of exceptional health…only published in Russian, and thus unknown in the West. Young biologists from the University of Los Angeles have overturned conventional wisdom and used molecular biology to demonstrate the powerful effects of fasting. This research suggests a wide-ranging potential, which could include treatments for the disease of the century, cancer. If these scientists are right, maybe our approach to disease and treatment will need a rethink.
Pier Paolo Pasolini sets out to interview Italians about sex, apparently their least favorite thing to talk about in public: he asks children if they know where babies come from; asks old and young women if they support gender equality; asks both sexes if a woman's virginity still matters, what do they think of homosexuality, if divorce should be legal, or if they support the recent abolition of brothels. He interviews blue-collar workers, intellectuals, college students, rural farmers, the bourgeoisie, and every other kind of people, painting a vivid portrait of a rapidly-industrializing Italy, hanging between modernity and tradition — toward both of which Pasolini shows equal distrust.
In this two-hour special, NOVA captures the turmoil that tore apart the community of Dover, Pennsylvania in one of the latest battles over teaching evolution in public schools. Featuring trial reenactments based on court transcripts and interviews with key participants, including expert scientists and Dover parents, teachers, and town officials, "Judgment Day: Intelligent Design on Trial" follows the celebrated federal case of Kitzmiller v. Dover School District.
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.
