From magic mushrooms to athlete's foot to penicillin, fungi are everywhere. Learn about fungal organisms that live within our bodies, grow beneath our feet, float in the air and help create some of the foods and beverages we consume. Follow professionals as they battle mold inside the walls of one moldy home. Visit the Phillips Mushroom Farms, America's largest producer of specialty mushrooms and finally see how scientists are looking for way to use fungi to fuel cars and clean up hazardous waste.

From the beginning of time we've worked to protect ourselves against the very element that keeps us alive...Water. We love it and hate it. With water covering 75% of the Earth's surface, it's no wonder we struggle to stay safe and dry. We fight against ferocious weather and floods with state-of-the-art roofing, wraps, tarps, tunnels, clothing, boats, and much more... devising extreme tests to probe the limits of our modern waterproof technology.

An inside look at the secret protocols, elite security and hidden history of the world's most public of private residences. What is the most secret room in the White House and what makes it so powerful? What secret visitors have been to the White House--invited or not? What kind of background checks are needed to work at the White House? What security measures go into effect if the White House is under attack? For over 200 years, the White House has functioned as a Presidential residence, Executive Office and national command center. But more guarded than the White House itself--are its secrets. Secrets that have remained untold...until now.

America's infrastructure is collapsing. Tens of thousands of bridges are structurally deficient or functionally obsolete. A third of the nation's highways are in poor or mediocre shape. Massively leaking water and sewage systems are creating health hazards and contaminating rivers and streams. Weakened and under-maintained levees and dams tower over communities and schools. And the power grid is increasingly maxed out, disrupting millions of lives and putting entire cities in the dark. The Crumbling of America explores these problems using expert interviews, on location shooting and computer generated animation to illustrate the kinds of infrastructure disasters that could be just around the bend.

Their soaring height is imposing. Their narrow design makes them some of the most difficult and dangerous structures to move -- from the 100-foot-tall obelisks of Ancient Egypt to the 1,483 foot tall Petronas Towers in Kuala Lumpur. Those that dare try to move these tall structures face almost certain defeat. Yet, despite the risks our team proves it can be done -- first by peering into the future to move two of the world's tallest skyscrapers, and then taking on a present-day challenge never before attempted -- simultaneously moving two towering silos connected by a common wall.

In 1943, a B-25 Mitchell, WWII's most versatile twin-engine bomber, crash-landed in South Carolina. It sank 150 feet to the bottom of a lake and over time was forgotten. Now, 60 years later, a local doctor is determined to raise the giant bomber intact and give it to a museum. Our team--divers, engineers, and preservationists--takes on the job of moving the 20,000-pound bomber to the surface, while faced with the challenges of working in nearly zero-visibility murky waters and the wrath of an approaching hurricane, plus fear that the plane may be breaking apart!

How do you move a 180 foot railroad bridge? An 8 story lighthouse? A 500 ton oil rig? Or an entire beach all in one week? This two-part compilation of last season's Mega Movers highlights the travels and travails of relocating the biggest, heaviest and least mobile structures imaginable. You'll see all the crucial steps from planning to placement as highly skilled movers tackle the impossible knowing that an inch miscalculation here or there can mean the difference between a successful move and disaster. Will these mega structures find their way safely to a new home or will they disintegrate and be lost for all eternity?

Mt Vesuvius is the world's most dangerous volcano, and it threatens three million people. It was responsible for the most famous natural disaster of ancient history, the eruption that destroyed the Roman city of Pompeii. And its most recent blast was caught on film in 1944. Today Vesuvius is the most densely populated volcano in the world. Now recent scientific discoveries show that it is capable of an eruption larger than ever before thought possible and that hidden beneath Vesuvius there is a vast magma chamber of boiling hot rock, ready to come out.

The San Andreas Fault runs roughly 800 miles through some of the most valuable real estate in the world. The southern section hasn't had a significant quake for over 300 years and is now primed and ready for another "big one." This new series takes a trip along the most famous fault line in the world and examine the geology that gives it its immense destructive power. It's an investigation given new urgency by recent warnings from 300 of America's leading scientists about the death and devastation that a major earthquake on the fault could unleash on Los Angeles.

It is one of the most man-made spaces on the planet, but everything in New York from the height of the skyscrapers to the way the subway was constructed to the position of the harbor is governed by the extraordinary forces that ultimately shaped this city. You can tell the geology of Manhattan at a glance by looking at the skyline. The skyscrapers of Midtown and Downtown are built on hard granite; the low-rise buildings in between are built on a soft, gravelly soil left over from the Ice Age. Learn how New Jersey and North Africa were neighbors 250 million years ago, how the rocks New York are built on are the remains of mountains that 450 million years ago were as tall as the Himalayas, and how Long Island is covered in rubble that remained as ice sheets retreated 10,000 years ago.

Africa's Sahara Desert is the size of the United States, making it the largest desert in the world. It's also the hottest place on the planet. But now an astonishing series of geological discoveries has revealed this searing wasteland hides a dramatically different past. Scientists have unearthed the fossils of whales, freshwater shells and even ancient human settlements. All clues to a story that would alter the course of human evolution and culminate in biggest climate change event of the last 10,000 years.

Some of the world's most powerful individuals belong to secret organizations. The Skull & Bones, the Bilderbergs, and the Tri-Lateral Commission are just a few of the groups that many suspect are conspiring to take over the world. Others believe they already have. What fuels such rampant conspiracy paranoia? We examine a number of these clandestine organizations, past and present, and reveal why so many people fear their nefarious agendas.

At the Last Supper, Jesus drank from a chalice, passed it to his Disciples, and it then vanished in history's mists. Some evidence suggests a follower collected Christ's blood in the Holy Grail and fled to England. Follow the first communion cup's elusive trail through those who sought it--from King Arthur to Indiana Jones.
