Megan Washington is one of Australia's premier singer/songwriters. And, since childhood, she has had a stutter. In this bold and personal talk, she reveals how she copes with this speech impediment—from avoiding the letter combination “st” to tricking her brain by changing her words at the last minute to, yes, singing the things she has to say rather than speaking them.
Tour the deep dark world of the East German state security agency known as Stasi. Uniquely powerful at spying on its citizens, until the fall of the Berlin Wall in 1989 the Stasi masterminded a system of surveillance and psychological pressure that kept the country under control for decades. Hubertus Knabe studies the Stasi — and was spied on by them. He shares stunning details from the fall of a surveillance state, and shows how easy it was for neighbor to turn on neighbor.
3D animation can bring scientific hypotheses to life. Molecular biologist (and TED Fellow) Janet Iwasa introduces a new open-source animation software designed just for scientists.
At the online University of the People, anyone with a high school diploma can take classes toward a degree in business administration or computer science â€” without standard tuition fees (though exams cost money).

The line between public and private has blurred in the past decade, both online and in real life, and Alessandro Acquisti is here to explain what this means and why it matters. In this thought-provoking, slightly chilling talk, he shares details of recent and ongoing research -- including a project that shows how easy it is to match a photograph of a stranger with their sensitive personal information.
Amanda Bennett and her husband were passionate and full of life all throughout their lives together -- and up until the final days, too. Bennett gives a sweet yet powerful talk on why, for the loved ones of the dying, having hope for a happy ending shouldn't warrant a diagnosis of "denial." She calls for a more heroic narrative for death -- to match the ones we have in life.
In the center of Caracas, Venezuela, stands the 45-story "Tower of David," an unfinished, abandoned skyscraper. But about eight years ago, people started moving in. Photographer Iwan Baan shows how people build homes in unlikely places, touring us through the family apartments of Torre David, a city on the water in Nigeria, and an underground village in China. Glorious images celebrate humanity's ability to survive and make a home -- anywhere.
What does it take to regrow bone in mass quantities? Typical bone regeneration — wherein bone is taken from a patient’s hip and grafted onto damaged bone elsewhere in the body — is limited and can cause great pain just a few years after operation. In an informative talk, Molly Stevens introduces a new stem cell application that harnesses bone’s innate ability to regenerate and produces vast quantities of bone tissue painlessly.
How do we solve the problem of the suburbs? Urbanist Jeff Speck shows how we can free ourselves from dependence on the car -- which he calls "a gas-belching, time-wasting, life-threatening prosthetic device" -- by making our cities more walkable and more pleasant for more people.
