Cambridge researcher Aubrey de Grey argues that aging is merely a disease -- and a curable one at that. Humans age in seven basic ways, he says, all of which can be averted.

Minority Report science adviser and inventor John Underkoffler demos g-speak -- the real-life version of the film's eye-popping, tai chi-meets-cyberspace computer interface. Is this how tomorrow's computers will be controlled?

You have got to see this one to the end. This is a major scientific breakthrough..

A little comedy mixed with talk about sustainability

Games are invading the real world -- and the runaway popularity of Farmville and Guitar Hero is just the beginning, says Jesse Schell. At the DICE Summit, he makes a startling prediction: a future where 1-ups and experience points break "out of the box" and into every part of our daily lives.

Using examples from vacations to colonoscopies, Nobel laureate and founder of behavioral economics Daniel Kahneman reveals how our "experiencing selves" and our "remembering selves" perceive happiness differently. This new insight has profound implications for economics, public policy -- and our own self-awareness.

Nathan Myhrvold of Intellectual Ventures demonstrated a STARWARS system at TED to fight malaria. It uses tiny lasers to shoot down disease-carrying mosquitoes, but that wasn't SCIFI enough.. so this one pOWNz the skeeterz with EXTRA lasers.. and some band named Three Days Grace..

This video is chock full of "I saw that on Star Trek" tech. Gel computers, nanoprobes, and the focus of the video which the presenter admits are basically "star trek replicators". Awesome.

Corvids are great.

The end result is unbelievably real.

This is worth it just to hear the Parrot sing "Happy Birthday" to Al Gore.

The most amazing talk on the the human brain I have ever seen.

Savage-Rumbaugh's work with bonobo apes, which can understand spoken language and learn tasks by watching, forces the audience to rethink how much of what a species can do is determined by biology -- and how much by cultural exposure.

Behavioral economist Dan Ariely studies the bugs in our moral code: the hidden reasons we think it's OK to cheat or steal (sometimes). Clever studies help make his point that we're predictably irrational -- and can be influenced in ways we can't grasp.

Behavioral economist Dan Ariely, the author of Predictably Irrational, uses classic visual illusions and his own counterintuitive (and sometimes shocking) research findings to show how we're not as rational as we think when we make decisions. Fascinating...

Career analyst Dan Pink examines the puzzle of motivation, starting with a fact that social scientists know but most managers don't: Traditional rewards aren't always as effective as we think. Listen for illuminating stories -- and maybe, a way forward.

Tony Robbins discusses the "invisible forces" that motivate everyone's actions -- and high-fives Al Gore in the front row.

Neuroanatomist Jill Bolte Taylor had an opportunity few brain scientists would wish for: One morning, she realized she was having a massive stroke. As it happened -- as she felt her brain functions slip away one by one, speech, movement, understanding -- she studied and remembered every moment. This is a powerful story about how our brains define us and connect us to the world and to one another.

Sir Ken Robinson makes an entertaining and profoundly moving case for creating an education system that nurtures (rather than undermines) creativity.

Johnny Lee demos his amazing Wii Remote hacks, which transform the $40 game piece into a digital whiteboard, a touchscreen and a head-mounted 3-D viewer.

This demo -- from Pattie Maes' lab at MIT, spearheaded by Pranav Mistry -- was the buzz of TED. It's a wearable device with a projector that paves the way for profound interaction with our environment. Imagine "Minority Report" and then some.

In keeping with the theme of TED2008, professor Stephen Hawking asks some Big Questions about our universe -- How did the universe begin? How did life begin? Are we alone? -- and discusses how we might go about answering them.

Artist Theo Jansen demonstrates the amazingly lifelike kinetic sculptures he builds from plastic tubes and lemonade bottles. His creatures are designed to move -- and even survive -- on their own.

Two Pilobolus dancers perform "Symbiosis." Does it trace the birth of a relationship? Or the co-evolution of symbiotic species? Music: "God Music," George Crumb; "Fratres," Arvo Part; "MorangoAlmost a Tango," Thomas Oboe Lee.
