From ordering movie tickets to booking a dentist appointment, mobile and web apps have made the tasks of daily life easier. But there are some things that an app can’t do. Standing in line at the pharmacy is one of them. In today’s talk, Lee Cronin asks: “Could we make a really cool universal chemistry set? In essence, could we app chemistry?” ...

A persistent sight in David Sengeh's childhood, growing up in Sierra Leone: amputees. Losing a limb was an all-too-common fact in the civil-war-torn region. But the aftermath was almost worse, Sengeh saw, as he watched family members and friends struggle with ill-fitting, uncomfortable prosthetics that hurt too much to wear. Here, the 201...

3D printing pioneer Avi Reichental is nostalgic for a time he never quite experienced -- a time of hyper-local, made-to-order, personalized craftsmanship. While the industrial revolution did a lot to advance humanity, says Reichental, it eradicated local manufacturing that people like his grandfather, a cobbler, excelled in. It atrophied socie...

A part on the outside of a spaceship that morphs, rather than requiring an astronaut to perform a risky maneuver. Plumbing pipes able to bend and flex based on the needs of the water flowing through them. Furniture that assembles itself, no screwdriver required. Buildings with the ability to repair themselves when something goes awry. Thes...

It's not often that you see a designer throw their creation on the ground and break it to smithereens. But that's exactly what TED Fellow Skylar Tibbits does in the video above. Why? Because he works in the Self-Assembly Lab at MIT. When the pieces break apart, they quickly re-assemble themselves, as if the film were playing in reverse. In...

It is the dawn of the era of 3D printing. From artificial prosthetics to very real human kidneys to filigree skull sculptures -- the number and variety of applications for this technology are growing, layer by printed layer. Combine this with the decreasing cost of owning a printer, as well as the cheaper cost of manufacturing in general, an...

Here's something else fun to do with a 3D printer: Designers at Free Art and Technology have created an open-source template to connect all the different building blocks you used as a kid: Legos, Tinkertoys, Lincoln Logs and more (and maybe in the future: littleBits, from today's TEDTalk...). It's a fascinating project, both for the exciting...

We've all heard of 3D printing. But what the heck is 4D printing? During TED Senior Fellow's Skylar Tibbits' talk at TED University on Thursday, he unveiled the concept -- 3D printed objects that seamlessly continue to expand, fold and harden into different forms (see video below). The talk has gotten a lot of attention. We spoke to Skylar a...

A powerful bitter sweet As race continues to dominate the news, it seems like perfect timing for artist Kara Walker’s latest piece, her first large-scale installation, housed in the shell of the old Domino Sugar Factory in Williamsburg, Brooklyn.

Eero Johannes Pitkänen introduces session 11 of TEDGlobal 2013 with a perfect synthesis of visual and sound effects. To a tinny metal drum-beat, colored Tetris blocks bounce up and down and in and out of shapes as each chord of sound has its impact. Describing himself as a “designer/illustrator during the day, musician during the night,” ...

Photo: James Duncan Davidson Chris Anderson comes on stage to acknowledge that the TED stage is more often the domain of the techno-optimist than the doomer. So, in somewhat stark contrast with Paul Guilding, the founder, chairman and CEO of the X Prize Foundation, Peter Diamandis now takes the stage. Diamandis starts off his talk wi...

Skylar Tibbits makes things that assemble themselves, with potential large-scale applications from self-adjusting water pipes to self-assembling structures in space. At his recently founded Self-Assembly Lab at MIT, he's pioneering 4D printing -- using smart materials to make objects that change shape and evolve. Here, he explains how 4D print...

Some great reads from around the internet today: Journalist Joan Juliet Buck tells the story behind her infamous Vogue puff piece on Asma al-Assad (above), saying that the First Lady of Syria "duped" her. Buck now writes of al-Assad's husband, "I didn’t know I was going to meet a murderer. There was no way of knowing that Assad, the meek...

Nesta Morgan is a storyboard artist. And while in the audience at a TED Salon in London in May, she found herself so inspired by several speakers that she took to sketching them -- and their ideas --  as they spoke. Above, see Nesta’s sketch of today’s TEDTalk, “Pam Warhurst: How we can eat our landscapes.” “I particularly enjoyed Pam's t...

In a corner of the Vancouver Convention Center -- set against a beautiful backdrop of Vancouver Harbour and the mountains of the North Shore, and right between a comfy simulcast lounge and a pop-up coffee and espresso shop -- it's hard to miss an eye-catching vintage red car. It's the anchor of Altair's exhibit gallery, showing off the possi...

President Barack Obama ended his 2013 State of the Union address just minutes ago saying, “We are citizens. It’s a word that doesn’t just describe our nationality or legal status. It describes the way we’re made … Well into our third century as a nation, it remains the task of us all, as citizens of these United States, to be the authors of the ...

"It takes courage to uncover the truth," says Chris Anderson, opening the first session of TED2015, Opening Gambit. "The speakers this week -- their courage and brilliance are going to rewire your brain. This dare thing is not just for them -- it's for all of us." These six speakers set the tone for Truth & Dare: The mega-challenge of...

As usual, the TED community has lots of news to share this week. Below, some highlights. A 4.37-lightyear starshot. Humanity has sent people to the moon and rovers to Mars. It might be about time we embark on interstellar travel. Russian philanthropist Yuri Milner, along with board member Stephen Hawking, unveiled a plan on Tuesday to sen...

TED Fellow Lucy McRae (watch her TED Talk) is a body architect -- an artist who explores how technology and the body may someday meet and merge. Her latest project is a fantastical and frothy music video for "Dream a Little Crazy” by Australian band Architecture in Helsinki. Watch the mouth-watering video above, and then read all about how Mc...

By Liz Jacobs and Helen Walters It’s often said that good design is invisible design — it makes things easy and delightful without us realizing it. But as host Chee Pearlman reminds us at the top of the session, we're here to honor the "D" in "TED." From the artistic to the architectural to the auditory, the eight speakers in this All-Sta...

In his TED Talk, “The shared experience of absurdity,” Charlie Todd shared the hilarity he creates for his fellow New Yorkers through flashmobs like the No Pants Subway Ride. The flashmob idea has, of course, spread widely. In the video above, watch one coordinated by the organizers of TEDxAden, a spontaneous musical performance in the elevat...

What's that too-often quoted aphorism? "Good artists copy; great artists steal"? In this nuanced conversation, biologist and founder of Biomimicry 3.8 Janine Benyus speaks with Tim Brown, chief executive of IDEO, to discuss what's really interesting about borrowing. Tim Brown: As a creative person, I’ve always believed that I can’t be creativ...

But some jobs -- and industries -- will still require a human touch. Technology researchers Andrew McAfee and Erik Brynjolfsson have a guess as to which ones. A surprising report published this spring projects that 30 percent of current jobs in the UK might be replaced by automation in the next 15 years. That number is 21 percent in Japan, 35 p...

In 2013, TED published more than 250 talks, each with an idea worth spreading. And yet, certain ideas seemed to resonate throughout the year, as if speakers at different events were singing parts of the same choral symphony. As 2013 draws to a close, here is a look at some of the big ideas we parsed this year. Consider it the rousing finale ...
