The Hackers

Hosted by

Science and technology now allow us to "hack" solutions to the biggest challenges of our time. But how far is too far? And what are the consequences of these hacks? We hear stories from TED speakers who dare to hack the brain, the climate, and even the animal kingdom in hopes of creating a better world.

Computer security expert Mikko Hyppönen describes discovering Brain and why the guys who wrote it never meant any harm. Stewart Brand, a legend in the tech industry for things he's created, says we have the technology to bring back animal species that we wiped out. Environmental scientist David Keith proposes a cheap and shocking way to address climate change. Inventor Jay Silver talks about the urge to play with the world around you. And neurosurgeon Andres Lozano talks about dramatic findings in deep brain stimulation.
