Latif Nasser: You have no idea where camels really come from


Camels are so well adapted to the desert that it's hard to imagine them living anywhere else. But what if we have them pegged all wrong? What if those big humps, feet and eyes were evolved for a different climate and a different time? In this talk, join Radiolab's Latif Nasser as he tells the surprising story of how a very tiny, very strange fossil upended the way he sees camels, and the world. This talk comes from the PBS special "TED Talks: Science & Wonder."

Adam Foss: A prosecutor's vision for a better justice system


When a kid commits a crime, the US justice system has a choice: prosecute to the full extent of the law, or take a step back and ask if saddling young people with criminal records is the right thing to do every time. In this searching talk, Adam Foss, a prosecutor with the Suffolk County District Attorney's Office in Boston, makes his case for a reformed justice system that replaces wrath with opportunity, changing people's lives for the better instead of ruining them.

Alexander Betts: Our refugee system is failing. Here's how we can fix it


A million refugees arrived in Europe this year, says Alexander Betts, and "our response, frankly, has been pathetic." Betts studies forced migration, the impossible choice for families between the camps, urban poverty and dangerous illegal journeys to safety. In this insightful talk, he offers four ways to change the way we treat refugees, so they can make an immediate contribution to their new homes. "There's nothing inevitable about refugees being a cost," Betts says. "They're human beings with skills, talents, aspirations, with the ability to make contributions -- if we let them."

Reshma Saujani: Teach girls bravery, not perfection


We're raising our girls to be perfect, and we're raising our boys to be brave, says Reshma Saujani, the founder of Girls Who Code. Saujani has taken up the charge to socialize young girls to take risks and learn to program -- two skills they need to move society forward. To truly innovate, we cannot leave behind half of our population, she says. "I need each of you to tell every young woman you know to be comfortable with imperfection."

Mary Bassett: Why your doctor should care about social justice

TEDMED 2015

Mary Bassett: Why your doctor should care about social justice


In Zimbabwe in the 1980s, Mary Bassett witnessed the AIDS epidemic firsthand, and she helped set up a clinic to treat and educate local people about the deadly virus. But looking back, she regrets not sounding the alarm for the real problem: the structural inequities embedded in the world's political and economic organizations, inequities that make marginalized people more vulnerable. These same structural problems exist in the United States today, and as New York City's Health Commissioner, Bassett is using every chance she has to rally support for health equity and speak out against racism. "We don't have to have all the answers to call for change," she says. "We just need courage."

Travis Kalanick: Uber's plan to get more people into fewer cars


Uber didn't start out with grand ambitions to cut congestion and pollution. But as the company took off, co-founder Travis Kalanick wondered if there was a way to get people using Uber along the same routes to share rides, reducing costs and carbon footprint along the way. The result: uberPOOL, the company's carpooling service, which in its first eight months took 7.9 million miles off the roads and 1,400 metric tons of carbon dioxide out of the air in Los Angeles. Now, Kalanick says carpooling could work for commuters in the suburbs, too. "With the technology in our pockets today, and a little smart regulation," he says, "we can turn every car into a shared car, and we can reclaim our cities starting today."

When you look at Muslim scholar Dalia Mogahed, what do you see: a woman of faith? a scholar, a mom, a sister? or an oppressed, brainwashed, potential terrorist? In this personal, powerful talk, Mogahed asks us, in this polarizing time, to fight negative perceptions of her faith in the media -- and to choose empathy over prejudice.

Al Gore: The case for optimism on climate change

TED2016

Al Gore: The case for optimism on climate change


Al Gore has three questions about climate change and our future. First: Do we have to change? Each day, global-warming pollution traps as much heat energy as would be released by 400,000 Hiroshima-class atomic bombs. This trapped heat is leading to stronger storms and more extreme floods, he says: "Every night on the TV news now is like a nature hike through the Book of Revelation." Second question: Can we change? We've already started. So then, the big question: Will we change? In this challenging, inspiring talk, Gore says yes. "When any great moral challenge is ultimately resolved into a binary choice between what is right and what is wrong, the outcome is foreordained because of who we are as human beings," he says. "That is why we're going to win this."

Raffaello D'Andrea: Meet the dazzling flying machines of the future


When you hear the word "drone," you probably think of something either very useful or very scary. But could they have aesthetic value? Autonomous systems expert Raffaello D'Andrea develops flying machines, and his latest projects are pushing the boundaries of autonomous flight -- from a flying wing that can hover and recover from disturbance to an eight-propeller craft that's ambivalent to orientation ... to a swarm of tiny coordinated micro-quadcopters. Prepare to be dazzled by a dreamy, swirling array of flying machines as they dance like fireflies above the TED stage.

Allan Adams: What the discovery of gravitational waves means

Allan Adams: What the discovery of gravitational waves means


More than a billion years ago, two black holes in a distant galaxy locked into a spiral, falling inexorably toward each other, and collided. "All that energy was pumped into the fabric of time and space itself," says theoretical physicist Allan Adams, "making the universe explode in roiling waves of gravity." About 25 years ago, a group of scientists built a giant laser detector called LIGO to search for these kinds of waves, which had been predicted but never observed. In this mind-bending talk, Adams breaks down what happened when, in September 2015, LIGO detected an unthinkably small anomaly, leading to one of the most exciting discoveries in the history of physics.

Magda Sayeg: How yarn bombing grew into a worldwide movement


Textile artist Magda Sayeg transforms urban landscapes into her own playground by decorating everyday objects with colorful knit and crochet works. These warm, fuzzy "yarn bombs" started small, with stop sign poles and fire hydrants in Sayeg's hometown, but soon people found a connection to the craft and spread it across the world. "We all live in this fast-paced, digital world, but we still crave and desire something that's relatable," Sayeg says. "Hidden power can be found in the most unassuming places, and we all possess skills that are just waiting to be discovered."

Ivan Coyote: Why we need gender-neutral bathrooms


There are a few things that we all need: fresh air, water, food, shelter, love ... and a safe place to pee. For trans people who don't fit neatly into the gender binary, public restrooms are a major source of anxiety and the place where they are most likely to be questioned or harassed. In this poetically rhythmic talk, Ivan Coyote grapples with complex and intensely personal issues of gender identity and highlights the need for gender-neutral bathrooms in all public places.

Jocelyne Bloch: The brain may be able to repair itself -- with help


Through treating everything from strokes to car accident traumas, neurosurgeon Jocelyne Bloch knows the brain's inability to repair itself all too well. But now, she suggests, she and her colleagues may have found the key to neural repair: Doublecortin-positive cells. Similar to stem cells, they are extremely adaptable and, when extracted from a brain, cultured and then re-injected in a lesioned area of the same brain, they can help repair and rebuild it. "With a little help," Bloch says, "the brain may be able to help itself."

Dorothy Roberts: The problem with race-based medicine


Social justice advocate and law scholar Dorothy Roberts has a precise and powerful message: Race-based medicine is bad medicine. Even today, many doctors still use race as a medical shortcut; they make important decisions about things like pain tolerance based on a patient's skin color instead of medical observation and measurement. In this searing talk, Roberts lays out the lingering traces of race-based medicine -- and invites us to be a part of ending it. "It is more urgent than ever to finally abandon this backward legacy," she says, "and to affirm our common humanity by ending the social inequalities that truly divide us."

Mike Velings: The case for fish farming


We're headed towards a global food crisis: Nearly 3 billion people depend on the ocean for food, and at our current rate we already take more fish from the ocean than it can naturally replace. In this fact-packed, eye-opening talk, entrepreneur and conservationist Mike Velings proposes a solution: Aquaculture, or fish farming. "We must start using the ocean as farmers instead of hunters," he says, echoing Jacques Cousteau. "The day will come where people will demand farmed fish on their plates that's farmed well and farmed healthy -- and refuse anything less."

Pardis Sabeti: How we'll fight the next deadly virus


When Ebola broke out in March 2014, Pardis Sabeti and her team got to work sequencing the virus's genome, learning how it mutated and spread. Sabeti immediately released her research online, so virus trackers and scientists from around the world could join in the urgent fight. In this talk, she shows how open cooperation was key to halting the virus ... and to attacking the next one to come along. "We had to work openly, we had to share and we had to work together," Sabeti says. "Let us not let the world be defined by the destruction wrought by one virus, but illuminated by billions of hearts and minds working in unity."

Dambisa Moyo: Economic growth has stalled. Let's fix it


Economic growth is the defining challenge of our time; without it, political and social instability rises, human progress stagnates and societies grow dimmer. But, says economist Dambisa Moyo, dogmatic capitalism isn't creating the growth we need. As she shows, in both state-sponsored and market-driven models, capitalism is failing to solve social ills, fostering corruption and creating income inequality. Moyo surveys the current economic landscape and suggests that we have to start thinking about capitalism as a spectrum so we can blend the best of different models together to foster growth.
