Josh Luber is a "sneakerhead," a collector of rare or limited sneakers. With their insatiable appetite for exclusive sneakers, these tastemakers drive marketing and create hype for the brands they love, specifically Nike, which absolutely dominates the multi-billion dollar secondary market for sneakers. Luber's company, Campless, collects data about this market and analyzes it for collectors and investors. In this talk, he takes us on a journey into this complicated, unregulated market and imagines how it could be a model for a stock market for commerce.
As a gay couple in San Francisco, Jenni Chang and Lisa Dazols had a relatively easy time living the way they wanted. But outside the bubble of the Bay Area, what was life like for people still lacking basic rights? They set off on a world tour in search of "Supergays," LGBT people who were doing something extraordinary in the world. In 15 countries across Africa, Asia and South America -- from India, recently home to the world's first openly gay prince, to Argentina, the first country in Latin America to grant marriage equality -- they found the inspiring stories and the courageous, resilient and proud Supergays they had been looking for.
Search engines have become our most trusted sources of information and arbiters of truth. But can we ever get an unbiased search result? Swedish author and journalist Andreas Ekström argues that such a thing is a philosophical impossibility. In this thoughtful talk, he calls on us to strengthen the bonds between technology and the humanities, and he reminds us that behind every algorithm is a set of personal beliefs that no code can ever completely eradicate.
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.
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?
A genre unto herself, Kaki King fuses the ancient tradition of working with one's hands with digital technology, projection-mapping imagery onto her guitar in her groundbreaking multimedia work "The Neck Is a Bridge to the Body." Using her guitar's neck like a keyboard, she plays an intricate melody as she takes the audience on a musical journey of light and sound. She calls it "guitar as paintbrush."
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.
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?
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."
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.
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."
Cave explorer and geologist Francesco Sauro travels to the hidden continent under our feet, surveying deep, dark places inside the earth that humans have never been able to reach before. In the spectacular tepuis of South America, he finds new minerals and insects that have evolved in isolation, and he uses his knowledge of these alien worlds to train astronauts.
Aboard an overloaded ship carrying more than 500 refugees, a young woman becomes an unlikely hero. This single, powerful story, told by Melissa Fleming of the UN's refugee agency, gives a human face to the sheer numbers of human beings trying to escape to better lives ... as the refugee ships keep coming ...
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.
Designer Tea Uglow is creating a future in which humanity's love for natural solutions and simple tools can coexist with our need for information and the devices that provide us with it. "Reality is richer than screens," she says. "We can have a happy place filled with the information we love that feels as natural as switching on lightbulb."
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.
When two bodies wearing identical wetsuits washed ashore in Norway and the Netherlands, journalist Anders Fjellberg and photographer Tomm Christiansen started a search to answer the question: who were these people? What they found and reported in Norway's "Dagbladet" is that everybody has a name, everybody has a story and everybody is someone.
Investigative journalist Will Potter is the only reporter who has been inside a Communications Management Unit, or CMU, within a US prison. These units were opened secretly, and radically alter how prisoners are treated -- even preventing them from hugging their children. Potter, a TED Fellow, shows us who is imprisoned here, and how the government is trying to keep them hidden. "The message was clear," he says. "Don't talk about this place."

Using examples from birdsong, the natural lilt of emphatic language and even a cooking pan lid, singer-songwriter and TED Fellow Meklit Hadero shows how the everyday soundscape, even silence, makes music. "The world is alive with musical expression," she says. "We are already immersed."
You might not know this: Many of the medicines we take -- common drugs like Ambien and everyday aspirin -- were only ever tested on men. And the unknown side effects for women can be dangerous, even deadly. Alyson McGregor studies the differences between male and female patients; in this fascinating talk she explains how the male model became our framework for medical research ... and what women and men need to ask their doctors to get the right care for their bodies.
Can we end hunger and poverty, halt climate change and achieve gender equality in the next 15 years? The governments of the world think we can. Meeting at the UN in September 2015, they agreed to a new set of Global Goals for the development of the world to 2030. Social progress expert Michael Green invites us to imagine how these goals and their vision for a better world can be achieved.
At his lab at the University of Pennsylvania, Vijay Kumar and his team have created autonomous aerial robots inspired by honeybees. Their latest breakthrough: Precision Farming, in which swarms of robots map, reconstruct and analyze every plant and piece of fruit in an orchard, providing vital information to farmers that can help improve yields and make water management smarter.
For musician Teitur, singing is about giving away a piece of yourself to others. "If your intentions are to impress people or to get the big applause at the end," he says, "then you are taking, not giving." Listen as he plays on stage at TED2015, offering two songs about love, distance and home.
Designer and architect Neri Oxman is leading the search for ways in which digital fabrication technologies can interact with the biological world. Working at the intersection of computational design, additive manufacturing, materials engineering and synthetic biology, her lab is pioneering a new age of symbiosis between microorganisms, our bodies, our products and even our buildings.
Can we, as adults, grow new neurons? Neuroscientist Sandrine Thuret says that we can, and she offers research and practical advice on how we can help our brains better perform neurogenesis—improving mood, increasing memory formation and preventing the decline associated with aging along the way.
What do you want to be when you grow up? Well, if you're not sure you want to do just one thing for the rest of your life, you're not alone. In this illuminating talk, writer and artist Emilie Wapnick describes the kind of people she calls "multipotentialites" -- who have a range of interests and jobs over one lifetime. Are you one?
More than 40 million people worldwide suffer from Alzheimer's disease, and that number is expected to increase drastically in the coming years. But no real progress has been made in the fight against the disease since its classification more than 100 years ago. Scientist Samuel Cohen shares a new breakthrough in Alzheimer's research from his lab as well as a message of hope. "Alzheimer's is a disease," Cohen says, "and we can cure it."
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.
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.
