Siddharthan Chandran: Can the damaged brain repair itself?


After a traumatic brain injury, it sometimes happens that the brain can repair itself, building new brain cells to replace damaged ones. But the repair doesn't happen quickly enough to allow recovery from degenerative conditions like motor neuron disease (also known as Lou Gehrig's disease or ALS). Siddharthan Chandran walks through some new techniques using special stem cells that could allow the damaged brain to rebuild faster.

Rupal Patel: Synthetic voices, as unique as fingerprints


Many of those with severe speech disorders use a computerized device to communicate. Yet they choose between only a few voice options.

Dan Berkenstock: The world is one big dataset. Now, how to photograph it ...


We're all familiar with satellite imagery, but what we might not know is that much of it is out of date. That's because satellites are big and expensive, so there aren't that many of them up in space. As he explains in this fascinating talk, Dan Berkenstock and his team came up with a different solution, designing a cheap, lightweight satellite with a radically new approach to photographing what's going on on Earth.

In a heartening talk, Pope makes the case for gender-neutral toys and gives a rousing call to action to all kids who feel powerless.

Agarwal shares his vision of blended learning, where teachers create the ideal learning experience for 21st century students.

Palms sweat, hands shake, vision blurs, and the brain says RUN: it's stage fright. In this charming, tuneful little talk, Joe Kowan talks about how he conquered it.

Yves Morieux: As work gets more complex, 6 rules to simplify

(Rule One: Understand what your colleagues actually do.)

Paula Johnson: His and hers … healthcare

TEDWomen 2013

Paula Johnson: His and hers … healthcare


Every cell in the human body has a sex, which means that men and women are different right down to the cellular level. Yet too often, research and medicine ignore this insight -- and the often startlingly different ways in which the two sexes respond to disease or treatment. As pioneering doctor Paula Johnson describes in this thought-provoking talk, lumping everyone in together means we essentially leave women's health to chance. It's time to rethink.
