Size Matters

The inside story of SpaceX's plan to get humanity to Mars, providing an unprecedented glimpse into one of the world's most revolutionary companies. A behind-the-scenes journey with Elon Musk and his engineers as they persevere amidst both disheartening setbacks and huge triumphs to advance the space industry faster than we ever thought possible.

Documentary-maker David Malone delves into the secrets of ocean waves. In an elegant and original film, he finds that waves are not made of water, that some waves travel sideways and that the sound of the ocean comes not from water but from bubbles. Waves are not only beautiful but also profoundly important, and there is a surprising connection between the life cycle of waves and the life of human beings.

Anatomist Alice Roberts embarks on a quest to rebuild her own body from scratch, taking inspiration from the very best designs the natural world has to offer.

The biggest tech revolution of the 21st century isn’t digital, it’s biological. A breakthrough called CRISPR gives us unprecedented control over the basic building blocks of life. It opens the door to curing disease, reshaping the biosphere, and designing our own children. This documentary is a provocative exploration of CRISPR’s far-reaching implications, through the eyes of the scientists who discovered it, the families it’s affecting, and the genetic engineers who are testing its limits.

A group of renowned cosmologists and astrophysicist are in search of a realistic picture of the universe. Their research and observational discoveries point in a direction diametrically opposed to the predominant Bog Bang theory - this leads to a series of sociological situations that verge on the extreme dogma controls wielded against Copernicus and Galileo in the past; only now against our protagonists of the 21st century. This is a controversial science documentary touching on the nerve of everything astronomers and cosmologist claim they know about the universe today. - Written by Meyers, Randall

The Scorpions belong to the oldest land-based arachnides with over 1800 different species known to exist. Usually, they do not surpass the size of 10cm in length, but exceptions are know, such as the Emperor Scorpion (Pandinus imperator) which can grow up to become over 20cm in size. Scorpions are mostly active at night and hide away during the day. Take a look into the live of these amazing creatures!

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.

This documentary examines theories behind the creation of gamma ray bursts, destructive explosions in space that can wipe out entire star systems.

Four young Americans who've each suffered a Traumatic Brain Injury emerge from their comas at a New Jersey medical facility. Their eyes may be open, but now the real challenge for each of the patients, their families, their doctors and their therapists begins. Brain healing isn't predictable, we're told, and certainly is not guaranteed. So with each 'major' step forward that is observed (opening one's eyes, bending a thumb upon command, vocalizing a word, answering a question correctly) comes a sense of jubilant relief and hope from the families of these patients, but as we soon see, the more a patient progresses, the more difficult things can be for all involved. Moments of faith & hope contrast with disappointments & frustrations, moments of confidence with moments of doubt. It's difficult to watch, and unimaginable to have to ever live through.

Is building our own starship Enterprise possible? Will we ever travel between the stars as easily as they do in Star Trek? JJ Abrams' new feature, Star Trek Into Darkness, hits the screen in a golden age of scientific discoveries. HISTORY is there, giving viewers a deep look behind the scenes, on the set, and into the science–amazing new exoplanets, the physics of Warp drive, and the ideas behind how we might one day live in a Star Trek Universe.

Kosmologisch - Die Entstehung Des Himmels

Professor Iain Stewart reveals the story behind the Scottish physicist who was Einstein's hero; James Clerk Maxwell. Maxwell's discoveries not only inspired Einstein, but they helped shape our modern world - allowing the development of radio, TV, mobile phones and much more. Despite this, he is largely unknown in his native land of Scotland. Scientist Iain Stewart sets out to change that, and to celebrate the life, work and legacy of the man dubbed "Scotland's Forgotten Einstein".

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.

A documentary on Al Gore's campaign to make the issue of global warming a recognized problem worldwide.

Raising angora rabbits for wool; new marine navigation and safety technology; kitchen gadgets; developing new rose varieties.

Concern over global climate change may be at an all-time high, but climate change is nothing new - the earth's climate always followed natural cycles of warming and cooling. In Unstoppable Solar Cycles, Dr. Willie Soon and Dr. David Legates challenge the popular idea that human-generated CO2, is causing catastrophic global warming. These scientists propose an alterantive theory - that the current warming has more to do with solar activity than with human activity.

Kate Humble and Helen Czerski reveal the inner workings of the sun and investigate why scientists think changes in the sun's behaviour may have powerful effects on our climate.

Dr Helen Czerski delves into the Horizon archive to chart the transformation of a little-known theory into one of the greatest scientific undertakings in history.

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.

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.
