Shifting Sands
The Mojave- a landscape of extreme and fragile beauty- will encounter new challenges with the coming climate change. Desert field researchers tell the story in their words and share their experiences with us. Joshua trees, Bighorn sheep, pupfish, desert springs, and even the soil crust itself face new problems.

The Secret Life of Chaos
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?
In this documentary, Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science – how does a universe that starts off as dust end up with intelligent life? How does order emerge from disorder?
It’s a mindbending, counterintuitive and for many people a deeply troubling idea. But Professor Al-Khalili reveals the science behind much of beauty and structure in the natural world and discovers that far from it being magic or an act of God, it is in fact an intrinsic part of the laws of physics. Amazingly, it turns out that the mathematics of chaos can explain how and why the universe creates exquisite order and pattern.

Earth 2100
Experts say over the next hundred years the “perfect storm” of population growth, resource depletion and climate change could converge with catastrophic results.
In order to plan for the worst, we must anticipate it. In that spirit, guided by some of the world’s experts, ABC News’ “Earth 2100,” hosted by Bob Woodruff, will journey through the next century and explore what might be our worst-case scenario.

New Swirled Order (2009)
Where does this mysterious crop circle phenomena come from? Is it done by man as a joke? So why do people have extraordinary experiences then? Flying ball of lights were seen in and around crop cirlces. Or is it an alien intelligence which try to communicate with us? The geometry which can be found in crop circles, inculed a lot of mathematics which can be also found in nature.
The End of the Line
The world’s first major documentary about the devastating effect of overfishing premiered at Sundance Film Festival
Imagine an ocean without fish. Imagine your meals without seafood. Imagine the global consequences. This is the future if we do not stop, think and act.
Jamie Oliver’s wish: Teach every child about food
Sharing powerful stories from his anti-obesity project in Huntington, W. Va., TED Prize winner Jamie Oliver makes the case for an all-out assault on our ignorance of food.
Parallel universe
Everything you’re about to read here seems impossible and insane, beyond science fiction. Yet it’s all true.
Scientists now believe there may really be a parallel universe – in fact, there may be an infinite number of parallel universes, and we just happen to live in one of them. These other universes contain space, time and strange forms of exotic matter. Some of them may even contain you, in a slightly different form. Astonishingly, scientists believe that these parallel universes exist less than one millimeter away from us. In fact, our gravity is just a weak signal leaking out of another universe into ours.
The same but different
For years parallel universes were a staple of the Twilight Zone. Science fiction writers loved to speculate on the possible other universes which might exist. In one, they said, Elvis Presley might still be alive or in another the British Empire might still be going strong. Serious scientists dismissed all this speculation as absurd. But now it seems the speculation wasn’t absurd enough. Parallel universes really do exist and they are much stranger than even the science fiction writers dared to imagine.
