Harald Haas: Forget Wi-Fi. Meet the new Li-Fi Internet


What if we could use existing technologies to provide Internet access to the more than 4 billion people living in places where the infrastructure can't support it? Using off-the-shelf LEDs and solar cells, Harald Haas and his team have pioneered a new technology that transmits data using light, and it may just be the key to bridging the digital divide. Take a look at what the future of the Internet could look like.

Patrícia Medici: The coolest animal you know nothing about ... and how we can save it


Although the tapir is one of the world's largest land mammals, the lives of these solitary, nocturnal creatures have remained a mystery. Known as "the living fossil," the very same tapir that roams the forests and grasslands of South America today arrived on the evolutionary scene more than 5 million years ago. But threats from poachers, deforestation and pollution, especially in quickly industrializing Brazil, threaten this longevity. In this insightful talk, conservation biologist, tapir expert and TED Fellow Patrícia Medici shares her work with these amazing animals and challenges us with a question: Do we want to be responsible for their extinction?

Mathias Jud: Art that lets you talk back to NSA spies


In 2013, the world learned that the NSA and its UK equivalent, GCHQ, routinely spied on the German government. Amid the outrage, artists Mathias Jud and Christoph Wachter thought: Well, if they're listening ... let's talk to them. With antennas mounted on the roof of the Swiss Embassy in Berlin's government district, they set up an open network that let the world send messages to US and UK spies listening nearby. It's one of three bold, often funny, and frankly subversive works detailed in this talk, which highlights the world's growing discontent with surveillance and closed networks.

Hilary Cottam: Social services are broken. How we can fix them


When a family falls into crisis -- and it sometimes happens, thanks to unemployment, drugs, bad relationships and bad luck -- the social services system is supposed to step in and help them get back on track. As Hilary Cottam shows, in the UK a typical family in crisis can be eligible for services from more than 70 different agencies, but it's unlikely that any one of them can really make a difference. Cottam, a social entrepreneur herself, asks us to think about the ways we solve deep and complex social problems. How can we build supportive, enthusiastic relationships between those in need and those that provide help?

Cesar Harada: How I teach kids to love science


At the Harbour School in Hong Kong, TED Senior Fellow Cesar Harada teaches citizen science and invention to the next generation of environmentalists. He's moved his classroom into an industrial mega-space where imaginative kids work with wood, metal, chemistry, biology, optics and, occasionally, power tools to create solutions to the threats facing the world's oceans. There, he instills a universal lesson that his own parents taught him at a young age: "You can make a mess, but you have to clean up after yourself."

Nancy Lublin: How data from a crisis text line is saving lives

Nancy Lublin: How data from a crisis text line is saving lives


When a young woman texted DoSomething.org with a heartbreaking cry for help, the organization responded by opening a nationwide Crisis Text Line for people in pain. Nearly 10 million text messages later, the organization is using the privacy and power of text messaging to help people handle addiction, suicidal thoughts, eating disorders, sexual abuse and more. But there's an even bigger win: The anonymous data collected by text is teaching us when crises are most likely to happen -- and helping schools and law enforcement to prepare for them.

Daniel Levitin: How to stay calm when you know you'll be stressed

TEDGlobal>London

Daniel Levitin: How to stay calm when you know you'll be stressed


You're not at your best when you're stressed. In fact, your brain has evolved over millennia to release cortisol in stressful situations, inhibiting rational, logical thinking but potentially helping you survive, say, being attacked by a lion. Neuroscientist Daniel Levitin thinks there's a way to avoid making critical mistakes in stressful situations, when your thinking becomes clouded -- the pre-mortem. "We all are going to fail now and then," he says. "The idea is to think ahead to what those failures might be."

Christine Sun Kim: The enchanting music of sign language


Artist and TED Fellow Christine Sun Kim was born deaf, and she was taught to believe that sound wasn't a part of her life, that it was a hearing person's thing. Through her art, she discovered similarities between American Sign Language and music, and she realized that sound doesn't have to be known solely through the ears -- it can be felt, seen and experienced as an idea. In this endearing talk, she invites us to open our eyes and ears and participate in the rich treasure of visual language.

Jennifer Doudna: We can now edit our DNA. But let's do it wisely


Geneticist Jennifer Doudna co-invented a groundbreaking new technology for editing genes, called CRISPR-Cas9. The tool allows scientists to make precise edits to DNA strands, which could lead to treatments for genetic diseases … but could also be used to create so-called "designer babies." Doudna reviews how CRISPR-Cas9 works -- and asks the scientific community to pause and discuss the ethics of this new tool.

Alice Bows-Larkin: Climate change is happening. Here's how we adapt


Imagine the hottest day you've ever experienced. Now imagine it's six, 10 or 12 degrees hotter. According to climate researcher Alice Bows-Larkin, that's the type of future in store for us if we don't significantly cut our greenhouse gas emissions now. She suggests that it's time we do things differently—a whole system change, in fact—and seriously consider trading economic growth for climate stability.

Martin Pistorius: How my mind came back to life — and no one knew


Imagine being unable to say, "I am hungry," "I am in pain," "thank you," or "I love you,” -- losing your ability to communicate, being trapped inside your body, surrounded by people yet utterly alone. For 13 long years, that was Martin Pistorius’s reality. After contracting a brain infection at the age of twelve, Pistorius lost his ability to control his movements and to speak, and eventually he failed every test for mental awareness. He had become a ghost. But then a strange thing started to happen -- his mind began to knit itself back together. In this moving talk, Pistorius tells how he freed himself from a life locked inside his own body.
