S38 E16 Japan's Killer Quake

本集简介

The March 11 earthquake, the worst to ever strike Japan, spawned a tsunami with 30-foot-high waves that destroyed entire towns in minutes. In its worst crisis since World War II, Japan faces disaster on an epic scale: a death toll likely in the tens of thousands, massive destruction of homes and businesses, shortages of water and power, and the specter of a nuclear meltdown. With exclusive footage, NOVA captures the unfolding human drama and offers a clear-headed investigation of what triggered the earthquake, tsunami, and subsequent nuclear crisis. Can science and technology ever prevent devastation in the face of overwhelmingly powerful forces of nature?

Venom: Nature's Killer

Over the millennia, thousands of creatures have developed that most sophisticated of biological and chemical weapons: venom. These complex chemicals can scramble your brain signals, paralyze your muscles, puncture your blood cells, even begin digesting you from within. But nature's most potent toxins might also contain the keys to a new generation of advanced drugs. Such drugs might help doctors treat heart attacks, cancer, diabetes, and other serious illnesses. Follow NOVA crews as they join scientists on a dangerous quest to track down and capture the world's most venomous animals and find out how they can kill us and how they can save us.

Power Surge

Can emerging technology defeat global warming? The United States has invested tens of billions of dollars in clean energy projects as our leaders try to save our crumbling economy and our poisoned planet in one bold, green stroke. Are we finally on the brink of a green-energy "power surge," or is it all a case of too little, too late? From solar panel factories in China to a carbon capture-and-storage facility in the Sahara desert to massive wind and solar installations in the United States, NOVA travels the globe to reveal the surprising technologies that just might turn back the clock on climate change. NOVA will focus on the latest and greatest innovations, including everything from artificial trees to green reboots of familiar technologies like coal and nuclear energy. Can our technology, which helped create this problem, now solve it?
