Joseph DeSimone: What if 3D printing was 100x faster?

March 16, 2015


What we think of as 3D printing, says Joseph DeSimone, is really just 2D printing over and over ... slowly. Onstage at TED2015, he unveils a bold new technique -- inspired, yes, by Terminator 2 -- that's 25 to 100 times faster, and creates smooth, strong parts. Could it finally help to fulfill the tremendous promise of 3D printing?

David Eagleman: Can we create new senses for humans?

March 17, 2015


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.

Robyn Stein DeLuca: The good news about PMS

November 19, 2014


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.

She explores what we know and don't know about it -- and why the popular myth has persisted.

With lyricism and power, he explains why he continues his work today. Since 2000, attacks on humanitarian aid workers have tripled — and he wonders what that rise may signal to the world.

Andy Yen: Think your email's private? Think again

October 8, 2014


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.

Jon Gosier: The problem with "trickle-down techonomics"

October 16, 2014


Hooray for technology! It makes everything better for everyone!! Right? Well, no.

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."

Guy Winch: Why we all need to practice emotional first aid

November 7, 2014


We'll go to the doctor when we feel flu-ish or a nagging pain. So why don’t we see a health professional when we feel emotional pain: guilt, loss, loneliness?

He makes a compelling case to practice emotional hygiene — taking care of our emotions, our minds, with the same diligence we take care of our bodies.
