In a rousing talk, Kish demonstrates how this works and asks us to let go of our fear of the “dark unknown.”

David Eagleman: Can we create new senses for humans?
18 Mar 2015 6:10:45
As humans, we can perceive less than a ten-trillionth of all light waves. “Our experience of reality,” says neuroscientist David Eagleman, “is constrained by our biology.” He wants to change that. His research into our brain processes has led him to create new interfaces -- such as a sensory vest -- to take in previously unseen information about the world around us.
Robyn Stein DeLuca: The good news about PMS
17 Mar 2015 5:32:30
Everybody knows that most women go a little crazy right before they get their period, that their reproductive hormones cause their emotions to fluctuate wildly. Except: There's very little scientific consensus about premenstrual syndrome. Says psychologist Robyn Stein DeLuca, science doesn't agree on the definition, cause, treatment or even existence of PMS. She explores what we know and don't know about it -- and why the popular myth has persisted.
Vincent Cochetel was held hostage for 317 days in 1998, while working for the UN High Commissioner on Refugees in Chechnya.

Marc Kushner: Why the buildings of the future will be shaped by ... you
10 Mar 2015 5:02:19
"Architecture is not about math or zoning -- it's about visceral emotions," says Marc Kushner. In a sweeping — often funny — talk, he zooms through the past thirty years of architecture to show how the public, once disconnected, have become an essential part of the design process.

05 Mar 2015 6:00:05
Sending an email message is like sending a postcard, says scientist Andy Yen in this thought-provoking talk: Anyone can read it. Yet encryption, the technology that protects the privacy of email communication, does exist. It's just that until now it has been difficult to install and a hassle to use. Showing a demo of an email program he designed with colleagues at CERN, Yen argues that encryption can be made simple to the point of becoming the default option, providing true email privacy to all.

02 Mar 2015 6:29:22

Jon Gosier, a TED Fellow and tech investor, calls out the idea of "trickle-down techonomics," and shares powerful examples of how new tech can make things actually worse if it's not equally distributed. As he says, "the real innovation is in finding ways to include everyone."
