What might happen if the first manned mission to Mars crashes hundreds of miles from the rocket that would take them back home? Could they survive the crash, and travel across the brutal Martian surface to their home ship? We'll show what the astronauts would have to do to survive dust storms and space radiation, while extracting vital resources like water from the Martian soil itself. It's a dramatic vision of the very near future, where survival can depend on pre-industrial technology and human ingenuity.

They're the cooling corpses of stars like our sun, but new research proves white dwarfs are one of the driving forces of our universe. And they can tell us literally about the nature of the cosmos itself. Have scientists finally discovered how these small stars could be such massive galactic players?

Scientists genuinely don't know what most of our universe is made of. The atoms we're made from only make up four per cent. The rest is dark matter and dark energy (for 'dark', read 'don't know'). The Large Hadron Collider at CERN has been upgraded. When it's switched on in March 2015, its collisions will have twice the energy they did before. The hope is that scientists will discover the identity of dark matter in the debris. The stakes are high - because if dark matter fails to show itself, it might mean that physics itself needs a rethink.

brilliant mathematicians whose genius has profoundly affected us, but which tragically drove them insane and eventually led to them all committing suicide. Kurt Gödel, the introverted confidant of Einstein, proved that there would always be problems which were outside human logic. His life ended in a sanatorium where he starved himself to death. Finally, Alan Turing, the great Bletchley Park code breaker, father of computer science and homosexual, died trying to prove that some things are fundamentally unprovable.

Documentary telling the little-known story of how Darwin came to write his great masterpiece, On the Origin of Species, a book which explains the wonderful variety of the natural world as emerging out of death and the struggle of life. In the twenty years he took to develop a brilliant idea into a revolutionary book, Darwin went through a personal struggle every bit as turbulent as that of the natural world he observed. Fortunately, he left us an extraordinary record of his brilliant insights, observations of nature, and touching expressions of love and affection for those around him. He also wrote frank accounts of family tragedies, physical illnesses and moments of self-doubt, as he laboured towards publication of the book that would change the way we see the world.

West Perrine, Florida is a suburban ghetto in Southwest Miami. Over 63% of its residents are African-American and the unemployment rate is three times higher than the national rate. Violent crimes occur on a daily basis in this neighborhood of less than two square miles, where much of its adult male population winds up dead or in prison before their 30th birthday.

Dada 5000 (6'3", 270lbs., bench presses 670lbs) grew up blocks away from Perrine's MMA sensation, Kimbo Slice, and spent a year traveling the world as Kimbo's bodyguard. When Kimbo's manager buried video of Dada's spectacular backyard fight debut, for fear of Dada overshadowing his rising superstar, Dada leaves Kimbo's crew and makes a life-changing decisión. In his ring there is no doctors, no ambulance. Just two men in a 12'x12' ring battling in a savage bare-knuckle fight to the finish. Dada's gladiators give everything in the the backyard to feed their families and to try to fight their way out of hood. Meanwhile Dada returns to the ring, is discovered by professional scouts and gets his shot at turning pro in the octagon at the Hard Rock Hotel and Casino.
