Discovery Channel Pro Cycling Team's Lance Armstrong has not won every Tour de France since 1999 simply because he puts in extra miles of training, watches what he eats or even because he's dodged major injuries over his long career. People have gone to great lengths to explain away Lance Armstrong's greatness as an athlete. Some look for explanations in his physiology. Some say his will is just stronger than most. Others say he's ruthlessly demanded no less than excellence from his teammates. The truth lies somewhere in a combination of these factors, and few aspects of his story are less than fascinating. He leaves his career at the top of his game, with an unprecedented six Tour de France wins under his bike. But what's truly amazing is he's done this after being issued a near death sentence. In 1998 he was diagnosed with stage 3 testicular cancer that had metastasized in his lungs and brain. True to form, he battled the disease like a champion, and like most other mountains that have slowed Lance's forward motion, he eventually conquered it. But this is by no means a mountain he's left behind. Cancer was something that galvanized his resolve, both on and off the bike and contributed to his evolution as an athlete and as a man. After beating cancer, he began to take a serious look at training and became committed to improving his physiology. He also dedicated himself to chasing down even the slightest improvements in technology, living by the philosophy of "every second counts." From the communication system used by the team, the Nike clothing he wears, to the Trek bicycles he rides, no detail that would improve his chances on the bike is left untested. Lance has also embraced science in what may be the most important way possible. He's dedicated himself to conquering the disease that nearly destroyed him by raising research dollars through the Lance Armstrong Foundation. His athleticism and fighting spirit have become an inspiration to not only people battling cancer, but to anyone who appreciates a shining example of the indomitability of the human spirit. And as he rides into history to try and achieve his 7th Tour de France win, the world cheers him on. Because Lance Armstrong crosses the starting line a winner.

Deconstruction witnesses the construction of a house of the future to discover how it will keep us safe and relaxed, entertained and connected. The science behind new building materials and procedures, renewable energy technologies, and smart technologies are explored. Concrete has been around forever, but a building material called Autoclaved Aerated Concrete offers energy efficiency, sustainability and amazing fire resistance. The factory used to make it solves the mystery of its composition. A robotic house-building machine is in development that will build homes on earth, and even the moon. The space program is also bringing products like Aerogel insulation to home building. Renewable geothermal energy from the earth, and solar and wind power will become a key to sustainability. Not only will smart house technology become a partner that takes care of us at home, but it will also become more powerful and easier to use. The house of the future is here, and Deconstruction brings it to you.

Archangel Ancient Tree Archive and its founder, David Milarch, are turning to the past to ensure a future for all people on our planet. Their unique mission is to collect, clone, and replant the genetics from iconic and ancient trees that can best clean the planet's water, soil, and air, and give us the best hope to combat the effects of climate change. They are preserving the secret hidden in these threatened trees in living archives so that future generations can have a chance for a healthy environment.

For all the sweat, cash and time we proudly pour into our backyards, they should be much easier to maintain, right? Of course, Mother Nature has a mind of her own and is relentless in breaking down the order we work so hard to create. This special explores the obstacles nature throws up to thwart our best efforts as well as the tools and technology at our disposal to conquer the elements. The Science Channel goes behind the scenes at the Toro Company to marvel at the technology used to develop a lawn mower. We'll also uncover the science behind the art of composting and reveal why "dry rot" is anything but dry. This in-depth look at the science of the backyard featuring high-tech computer-generated images, hands-on demonstrations and the unique insight of host Steve Hanneman.
