Auke Ijspeert: A robot that runs and swims like a salamander


Roboticist Auke Ijspeert designs biorobots, machines modeled after real animals that are capable of handling complex terrain and would appear at home in the pages of a sci-fi novel. The process of creating these robots leads to better automata that can be used for fieldwork, service, and search and rescue. But these robots don't just mimic the natural world -- they help us understand our own biology better, unlocking previously unknown secrets of the spinal cord.

Melati and Isabel Wijsen: Our campaign to ban plastic bags in Bali


Plastic bags are essentially indestructible, yet they're used and thrown away with reckless abandon. Most end up in the ocean, where they pollute the water and harm marine life; the rest are burned in garbage piles, where they release harmful dioxins into the atmosphere. Melati and Isabel Wijsen are on a mission to stop plastic bags from suffocating their beautiful island home of Bali. Their efforts -- including petitions, beach cleanups, even a hunger strike -- paid off when they convinced their governor to commit to a plastic bag-free Bali by 2018. "Don't ever let anyone tell you that you're too young or you won't understand," Isabel says to other aspiring activists. "We're not telling you it's going to be easy. We're telling you it's going to be worth it."

Linda Liukas: A delightful way to teach kids about computers


Computer code is the next universal language, and its syntax will be limited only by the imaginations of the next generation of programmers. Linda Liukas is helping to educate problem-solving kids, encouraging them to see computers not as mechanical, boring and complicated but as colorful, expressive machines meant to be tinkered with. In this talk, she invites us to imagine a world where the Ada Lovelaces of tomorrow grow up to be optimistic and brave about technology and use it to create a new world that is wonderful, whimsical and a tiny bit weird.

Tania Simoncelli: Should you be able to patent a human gene?


A decade ago, US law said human genes were patentable -- which meant patent holders had the right to stop anyone from sequencing, testing or even looking at a patented gene. Troubled by the way this law both harmed patients and created a barrier to biomedical innovation, Tania Simoncelli and her colleagues at the ACLU challenged it. In this riveting talk, hear the story of how they took a case everybody told them they would lose all the way to the Supreme Court.

Elizabeth Lev: The unheard story of the Sistine Chapel


The Sistine Chapel is one of the most iconic buildings on earth -- but there's a lot you probably don't know about it. In this tour-de-force talk, art historian Elizabeth Lev guides us across the famous building's ceiling and Michelangelo's vital depiction of traditional stories, showing how the painter reached beyond the religious iconography of the time to chart new artistic waters. Five hundred years after the artist painted it, says Lev, the Sistine Chapel forces us to look around as if it were a mirror and ask, "Who am I, and what role do I play in this great theater of life?"

Yanis Varoufakis: Capitalism will eat democracy -- unless we speak up


Have you wondered why politicians aren't what they used to be, why governments seem unable to solve real problems? Economist Yanis Varoufakis, the former Minister of Finance for Greece, says that it's because you can be in politics today but not be in power -- because real power now belongs to those who control the economy. He believes that the mega-rich and corporations are cannibalizing the political sphere, causing financial crisis. In this talk, hear his dream for a world in which capital and labor no longer struggle against each other, "one that is simultaneously libertarian, Marxist and Keynesian."

Jill Farrant: How we can make crops survive without water


As the world's population grows and the effects of climate change come into sharper relief, we'll have to feed more people using less arable land.

Melvin Russell: I love being a police officer, but we need reform


We've invested so much in police departments as protectors that we have forgotten what it means to serve our communities, says Baltimore Police officer Lt. Colonel Melvin Russell. It's led to coldness and callousness, and it's dehumanized the police force. After taking over as district commander in one of Baltimore's toughest neighborhoods, Russell instituted a series of reforms aimed at winning back the trust of the community and lowering the violent crime rate. "Law enforcement is in a crisis," he says. "But it's not too late for all of us to build our cities and nation to make it great again."

Wael Ghonim: Let's design social media that drives real change


Wael Ghonim helped touch off the Arab Spring in his home of Egypt ... by setting up a simple Facebook page. As he reveals, once the revolution spilled onto the streets, it turned from hopeful to messy, then ugly and heartbreaking. And social media followed suit. What was once a place for crowdsourcing, engaging and sharing became a polarized battleground. Ghonim asks: What can we do about online behavior now? How can we use the Internet and social media to create civility and reasoned argument?

Rodrigo Bijou: Governments don't understand cyber warfare. We need hackers


The Internet has transformed the front lines of war, and it's leaving governments behind. As security analyst Rodrigo Bijou shows, modern conflict is being waged online between non-state groups, activists and private corporations, and the digital landscape is proving to be fertile ground for the recruitment and radicalization of terrorists. Meanwhile, draconian surveillance programs are ripe for exploitation. Bijou urges governments to end mass surveillance programs and shut "backdoors" -- and he makes a bold call for individuals to step up.

Jason deCaires Taylor: An underwater art museum, teeming with life


For sculptor Jason deCaires Taylor, the ocean is more than a muse -- it's an exhibition space and museum. Taylor creates sculptures of human forms and mundane life on land and sinks them to the ocean floor, where they are subsumed by the sea and transformed from lifeless stone into vibrant habitats for corals, crustaceans and other creatures. The result: Enigmatic, haunting and colorful commentaries about our transient existence, the sacredness of the ocean and its breathtaking power of regeneration.

Raymond Wang: How germs travel on planes -- and how we can stop them


Raymond Wang is only 17 years old, but he's already helping to build a healthier future. Using fluid dynamics, he created computational simulations of how air moves on airplanes, and what he found is disturbing -- when a person sneezes on a plane, the airflow actually helps to spread pathogens to other passengers. Wang shares an unforgettable animation of how a sneeze travels inside a plane cabin as well as his prize-winning solution: a small, fin-shaped device that increases fresh airflow in airplanes and redirects pathogen-laden air out of circulation.
