An examination of the extinction threat faced by frogs, which have hopped on Earth for some 250 million years and are a crucial cog in the ecosystem. Scientists believe they've pinpointed a cause for the loss of many of the amphibians: the chytrid fungus, which flourishes in high altitudes. Unfortunately, they don't know how to combat it. Included: an isolated forest in Panama that has yet to be touched by the fungus, thus enabling frogs to live and thrive as they have for eons.

Physicist Dr Helen Czerski takes us on a journey into the science of bubbles - not just fun toys, but also powerful tools that push back the boundaries of science.
Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand. It turns out that chaos theory answers a question that mankind has asked for millennia - how did we get here?
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.
Unmasks fraudulent cover-ups, wild speculations, and deceitful myths that have been presented as the absolute "facts" of evolution. Should evolutionism, the foundational faith of eastern mystical thought, be taught in schools as science, when Creationism, the foundational belief of Judeo-Christianity, has been expelled?

Tobacco, climate change, pesticides,... Never has scientific knowledge seemed so vast, detailed and shared. And yet it appears to be increasingly challenged. It is no longer surprising to see private corporations put strategies in place to confuse the public debate and paralyze political decision-making. Overwhelmed by excess of information, how can we, as citizens, sort out fact from fiction? One by one, this film dismantles the workings of this clever manoeuvre that aims to turn science against itself. Thanks to declassified archives, graphic animations and testimonies from experts, lobbyists and politicians, this investigation plunges us into the science of doubt. Along with a team of experts (philosophers, economists, cognitive scientists, political men, or even agnotologists), we explore concrete examples of doubt making and try to understand the whole process and the issues behind it.
A feature documentary about the journey of mankind to discover our true force and who we truly are. It is a quest through science and consciousness, individual and planetary, exploring our relationships with ourselves, the world around us and the universe as a whole.
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.

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.
Thirty distinguished astronomers are visited at their observatories throughout the world in this comprehensive report of astronomical theories, research, and discoveries.
Richard Feynman was a scientific genius with - in his words - a "limited intelligence". This dichotomy is just one of the characteristics that made him a fascinating subject. The Pleasure of Finding Things Out exposes us to many more of these intriguing attributes by featuring an extensive conversation with the acclaimed Nobel Prize winner. During the course of the interview, which was conducted in 1981, Feynman uses the undeniable power of the personal to convey otherwise challenging scientific theories. His colorful and lucid stories make abstract concepts tangible, and his warm presence is sure to inspire interest and awe from even the most reluctant student of science. His insights are profound, but his delivery is anything but dry and ostentatious.
Follow leading scientists around the world and to the edge of the universe on their quest to solve one of the greatest mysteries of the universe, the mysterious invisible “dark matter.”
