Fascinating - and unintentionally funny - experiments at Austria's famed Institute for Experimental Psychology involve a subject who for several weeks wears special glasses that reverse right and left and up and down. Unexpectedly, these macabre and somehow surrealist experiments reveal that our perception of these aspects of vision is not of an optical nature and cannot be relied on, while the unfortunate, Kafkaesque subject stubbornly struggles through a morass of continuous failures.

Thirty distinguished astronomers are visited at their observatories throughout the world in this comprehensive report of astronomical theories, research, and discoveries.

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.

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.

Is it possible for the entire world to switch to decentralized and renewable energy sources by 2030? In this inspiring documentary, we meet with German politicians, scientists, farmers, social workers, activists and visionaries who say yes, and who all push forward for a global change in climate by changing the local power supply sources to renewable energy. Director Carl-A. Fechner is not ready to give up on our planet just yet, and POWER TO CHANGE is a welcome antidote to the pessimism that defines our era's visions of the future.

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.”
