Stephen Hawking is known for his research into relativity, black holes, and quantum mechanics, as well as for the disease that has left him almost entirely paralyzed. But the theoretical cosmologist says that, were he to start from scratch, he wouldn't focus on physics.
Why are bed bugs so resistant to pesticides? How do whiskey, rye, and bourbon develop their unique flavor profile? What compounds in the natural world could be used for insect repellant or for treating AIDS? For the answers, we turn to the American Chemical Society conference. We'll discuss a few of the highlights presented at this week's meeting.
Researchers discovered the largest volcano on earth a thousand miles off the coast of Japan. Tamu Massif rivals some of the biggest volcanoes found in the solar system. Volcanology researcher Kayla Iacovino discusses what this giant can tell us about the inside of our planet.
Call it extremely personalized medicine. Tissue engineer Nina Tandon explains how in the future, we'll be able to grow replacement organs from our very own cells. In the future, that same technology will help develop custom designed drugs.
How do you predict the future? Technology leader Nicholas Negroponte accurately predicted some of the most prevalent devices we use to day — back in 1984. Negroponte explains how he makes predictions with great confidence.
Todd Humphreys forecasts the near-future of geolocation when millimeter-accurate GPS "dots" will enable you to find pin-point locations, index-search your physical possessions — or to track people without their knowledge. And the response to the sinister side of this technology may have unintended consequences of its own.
"I do spend time trying to think about what I cannot imagine." -- Nicholas Negroponte
Visions of the future don't just have to come from science fiction. There's very real technology today giving us clues about how our future lives might be transformed. So what might our future look like? And what does it take for an idea about the future to become a reality? In this hour, TED speakers make some bold predictions and explain how we might live in the future.
