Ces microbes qui nous gouvernent

Earth teems with a staggering variety of animals, including 9,000 kinds of birds, 28,000 types of fish, and more than 350,000 species of beetles. What explains this explosion of living creatures—1.4 million different species discovered so far, with perhaps another 50 million to go? The source of life's endless forms was a profound mystery until Charles Darwin brought forth his revolutionary idea of natural selection. But Darwin's radical insights raised as many questions as they answered. What actually drives evolution and turns one species into another? To what degree do different animals rely on the same genetic toolkit? And how did we evolve?

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.

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.

The film interweaves the personal accounts of polio survivors with the story of an ardent crusader who tirelessly fought on their behalf while scientists raced to eradicate this dreaded disease. Based in part on the Pulitzer Prize-winning book Polio: An American Story by David Oshinsky, Features interviews with historians, scientists, polio survivors, and the only surviving scientist from the core research team that developed the Salk vaccine, Julius Youngner.

The Hobbit Enigma examines one of the greatest controversies in science today: what did scientists find when they uncovered the tiny, human-like skeleton of a strange creature, known to many as the Hobbit, on the Indonesian island of Flores in 2003?

The use of embryonic stem cells has ignited fierce debate across the spiritual and political spectrum. But what if we could create manmade stem cells - or find super cells in adults that could forever replace embryonic cells and remove the controversy? Today, we are on the brink of a new era - an age where we may be able to cure our bodies of any illness. Stephen HAWKING has spent his life exploring the mysteries of the cosmos, now there is another universe that fascinates him - the one hidden inside our bodies - our own personal galaxies of cells.

Of the Seven Wonders of the Ancient World, the Pyramid is the only one to survive. Many believe that even with our 21st-century technology, we could not build anything like it today. Based on the most up-to-date research and the latest archaeological discoveries, here is how the Pyramid came to be.

Peter Westerveld, artist and visionary, doesn’t want institutions to resolve the problems linked to earth’s problems. Growing up in Africa, he witnessed the advance of the desert and dedicated himself to finding solutions for the ongoing erosion and desertification of the land. The film follows Peter and the NGO working with him to realise his project; to build contour trenches that capture and store rain water under the surface and replenish the desert land.

This 90-minute documentary brings to life Gavin Pretor-Pinney’s international bestseller, “The Cloudspotter’s Guide”, which draws on science, meteorology and mythology for a magical journey through the world of clouds. It is no dry treatise on the science of nephology but a playful trip through the varied beauty and distinctive personalities of the ten principal cloud types From the ethereal cirrus to the terrifying cumulonimbus, the film tells the story of the short but eventful life of clouds and their importance to our planet. Find out how immense quantities of water can stay up in the sky for so long and how lightning and thunder are created.

Deep down at the bottom of the ocean lies the mysterious world of the abyss. In the midst of boiling, toxic geysers, a rich ecosystem flourishes. This miracle is possible thanks to bacteria, micro-organisms crucial to all living beings. How can bacteria survive in such extreme conditions?

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.

In 1973 Yorkshire public television made a short film of the Nobel laureate while he was there. The resulting film, Take the World from Another Point of View, was broadcast in America as part of the PBS Nova series. The documentary features a fascinating interview, but what sets it apart from other films on Feynman is the inclusion of a lively conversation he had with the eminent British astrophysicist Fred Hoyle.

It has been said that 10,000 years from now only one name will still be remembered, that of Neil Armstrong. But in the four decades since he first set foot on the moon, Armstrong has become increasingly reclusive. Andrew Smith, author of the best-selling book Moondust, journeys across America to try and discover the real Neil Armstrong. He tracks down the people who knew Armstrong, from his closest childhood friend to fellow astronauts and Houston technicians, and even the barber who sold his hair, in a wry and sideways look at the reluctant hero of the greatest event of the 20th century.
