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.
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.
Lessons in optimism from very ill children inspire pediatric oncologist Jim Olson in his hunt for better treatments for brain tumors.
