Nearly six years after the earthquake and tsunami that triggered the unprecedented trio of meltdowns at the Fukushima Daiichi nuclear power plant, scientists and engineers are struggling to control an ongoing crisis at the wrecked plant. What’s next for Fukushima? What’s next for Japan? And what’s next for a world that seems determined to jettison one of our most important carbon-free sources of energy? NOVA investigates how the realities of climate change, the inherent limitations of renewable energy sources, and the optimism and enthusiasm of a new generation of nuclear engineers is seeding a renaissance in nuclear technology, all while the most recent disaster is still being managed.
This program examines a world wonder so elusive that most people have decided it must be mythical. Centuries of digging have turned up nothing – but it turns out the searchers were digging in the wrong place. Now, this film proves that the spectacular hanging gardens of Babylon did exist, and shows where they were, what they looked like and how they were constructed.
Some historians claim that the Egyptian chariot launched a technological and strategic revolution and was the secret weapon behind Egypt’s greatest era of conquest, known as the New Kingdom. But was the chariot really a revolutionary design? How decisive was its role in the bloody battles of the ancient world? A team of archaeologists, engineers, woodworkers and horse trainers builds and tests two accurate replicas of Egyptian royal chariots. Driving them to their limits in the desert outside Cairo, NOVA’s experts test the claim that the chariot marks a crucial turning point in ancient military history.

Follow scientists who are trying to determine if Titanoboa, a 43-foot snake, or a giant crocodilian was the apex predator in Cerrejon, Northern Colombia, 58 million years ago.
In Tampa, Florida, in February 2013, a giant hole opened up under the bedroom floor of Jeffrey Bush, swallowing the 36-year-old as he slept. His body was never found. Bush was a victim of a sinkhole – a growing worldwide hazard that lurks wherever limestone and other water-soluble rocks underpin the soil. When carbon dioxide in the air dissolves in rainwater, it forms a weak acid that attacks the soft rocks, riddling them with holes. Sinkholes can occur gradually when the surface subsides into bowl-shaped depressions or suddenly, when the ground gives way – often catastrophically.
