Mumbai, Delhi, Chennai, Kolkata -- all the major cities across India have one great thing in common: they welcome people arriving in search of work. But what lies at the other end of such openness and acceptance? Sadly, a shortage of housing for an estimated 100 million people, many of whom end up living in informal settlements.

Natsai Audrey Chieza is a designer on a mission -- to reduce pollution in the fashion industry while creating amazing new things to wear. In her lab, she noticed that the bacteria Streptomyces coelicolor makes a striking red-purple pigment, and now she's using it to develop bold, color-fast fabric dye that cuts down on water waste and chemical runoff, compared with traditional dyes. And she isn't alone in using synthetic biology to redefine our material future; think -- "leather" made from mushrooms and superstrong yarn made from spider-silk protein. We're not going to build the future with fossil fuels, Chieza says. We're going to build it with biology.
China is a huge laboratory of innovation, says retail expert Angela Wang, and in this lab, everything takes place on people's phones.

Since the widespread use of antibiotics began in the 1940s, we've tried to develop new drugs faster than bacteria can evolve -- but this strategy isn't working. Drug-resistant bacteria known as superbugs killed nearly 700,000 people last year, and by 2050 that number could be 10 million -- more than cancer kills each year. Can physics help? In a talk from the frontiers of science, radiation scientist David Brenner shares his work studying a potentially life-saving weapon: a wavelength of ultraviolet light known as far-UVC, which can kill superbugs safely, without penetrating our skin. Followed by a Q&A with TED Curator Chris Anderson.

Justin Baldoni wants to start a dialogue with men about redefining masculinity -- to figure out ways to be not just good men but good humans. In a warm, personal talk, he shares his effort to reconcile who he is with who the world tells him a man should be. And he has a challenge for men: "See if you can use the same qualities that you feel make you a man to go deeper," Baldoni says. "Your strength, your bravery, your toughness: Are you brave enough to be vulnerable? Are you strong enough to be sensitive? Are you confident enough to listen to the women in your life?"
We all know that when we make decisions in groups, they don't always go right -- and sometimes they go very wrong. How can groups make good decisions? With his colleague Dan Ariely, neuroscientist Mariano Sigman has been inquiring into how we interact to reach decisions by performing experiments with live crowds around the world. In this fun, fact-filled explainer, he shares some intriguing results -- as well as some implications for how it might impact our political system. In a time when people seem to be more polarized than ever, Sigman says, better understanding how groups interact and reach conclusions might spark interesting new ways to construct a healthier democracy.
The combined market capitalization of Amazon, Apple, Facebook and Google is now equivalent to the GDP of India. How did these four companies come to infiltrate our lives so completely? In a spectacular rant, Scott Galloway shares insights and eye-opening stats about their dominance and motivation -- and what happens when a society prizes shareholder value over everything else. Followed by a Q&A with TED Curator Chris Anderson. (Note: This talk contains graphic language.)
Leah Chase's New Orleans restaurant Dooky Chase changed the course of American history over gumbo and fried chicken. During the civil rights movement, it was a place where white and black people came together, where activists planned protests and where the police entered but did not disturb -- and it continues to operate in the same spirit today. In conversation with TEDWomen Curator Pat Mitchell, the 94-year old Queen of Creole Cuisine (who still runs the Dooky Chase kitchen) shares her wisdom from a lifetime of activism, speaking up and cooking.
The biggest obstacle to dealing with climate disruptions lies between your ears, says psychologist and economist Per Espen Stokes.

Step away from the doomsday narratives and learn how to make caring for the earth feel personable, do-able and empowering with this fun, informative talk.
In 2011, Teresa Njoroge was convicted of a financial crime she didn't commit -- the result of a long string of false accusations, increasing bribe attempts and the corrupt justice system in her home in Kenya. Once incarcerated, she discovered that most of the women and girls locked up with her were also victims of the same broken system, caught in a revolving door of life in and out of prison due to poor education and lack of economic opportunity. Now free and cleared by the courts of appeal, Njoroge shares how she's giving women in prison the skills, tools and support they need to break the cycle of poverty and crime and build a better life.
Look at the letters around you: on street signs, stores, restaurant menus, the covers of books. Whether you realize it or not, the letters are speaking to you, telling you something beyond the literal text -- that whatever they represent is modern or finely crafted or fantastical or zany. Learn to decode this secret language with lettering designer Martina Flor as she explains how altering the shapes, colors and textures of letters changes how we perceive them. (In Spanish with English subtitles)

Fresh food free of chemicals and pesticides is hard to come by in China: in 2016, the Chinese government revealed half a million food safety violations in just nine months. In the absence of safe, sustainable food sources, TED Fellow Matilda Ho launched China's first online farmers market, instituting a zero-tolerance test towards pesticides, antibiotics and hormones in food. She shares how she's growing her platform from the ground up and bringing local, organically grown food to the families that need it.
Niti Bhan studies business strategy for Africa's informal markets: the small shops and stands, skilled craftspeople and laborers who are the invisible engine that keeps the continent's economy running. It's tempting to think of these workers as tax-dodgers, even criminals -- but Bhan makes the case that this booming segment of the economy is legitimate and worthy of investment. "These are the fertile seeds of businesses and enterprises," Bhan says. "Can we start by recognizing these skills and occupations?"

In a wide-ranging conversation with journalist Stephanie Busari, Gurib-Fakim discusses the humble beginnings of her political career, what it's like to be both a person of faith and a scientist and why we need to value traditional African knowledge, among much more. "I don't think you should take yourself seriously," she says. "You need to have trust in what you can do, have confidence in yourself and give yourself a set of goals and just work towards them."
For the introverts among us, traditional forms activism like marches, protests and door-to-door canvassing can be intimidating and stressful. Take it from Sarah Corbett, a former professional campaigner and self-proclaimed introvert. She introduces us to "craftivism," a quieter form of activism that uses handicrafts as a way to get people to slow down and think deeply about the issues they're facing, all while engaging the public more gently. Who says an embroidered handkerchief can't change the world?
