What if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he's developing to harness "night-sky cooling" -- a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it -- which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.

In this joyful, heartfelt talk featuring demos of her wonderfully wacky creations, Simone Giertz shares her craft: making useless robots. Her inventions -- designed to chop vegetables, cut hair, apply lipstick and more -- rarely (if ever) succeed, and that's the point. "The true beauty of making useless things [is] this acknowledgment that you don't always know what the best answer is," Giertz says. "It turns off that voice in your head that tells you that you know exactly how the world works. Maybe a toothbrush helmet isn't the answer, but at least you're asking the question."

Trust is the foundation for everything we do. But what do we do when it's broken? In an eye-opening talk, Harvard Business School professor Frances Frei gives a crash course in trust: how to build it, maintain it and rebuild it -- something she worked on during a recent stint at Uber. "If we can learn to trust one another more, we can have unprecedented human progress," Frei says.

Children who live in rural areas can have a hard time getting to the doctor -- much less to an audiologist's clinic for expensive, complex tests to check their hearing. The result for too many kids is hearing loss caused by ear infections and other curable or preventable problems. That's why ear surgeon and TED Fellow Susan Emmett is working with 15 communities in rural Alaska to create a simple, low-cost test that only requires a cell phone. Learn more about her work and how it could change the lives of children who don't have access to hearing care.

In a poetic, personal talk, TED Fellow Katlego Kolanyane-Kesupile examines the connection between her modern queer lifestyle and her childhood upbringing in a rural village in Botswana. "In a time where being brown, queer, African and seen as worthy of space means being everything but rural, I fear that we're erasing the very struggles that got us to where we are now," she says. "Indigenizing my queerness means bridging the many exceptional parts of myself."

In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.

Public libraries have always been about more than just books -- and their mission of community support has taken on new urgency during the current opioid epidemic. After witnessing overdoses at her library in Philadelphia, Chera Kowalski learned how to administer naloxone, a drug that reverses the effects of narcotics, and she's put it to use to save patrons' lives. In this personal talk, she shares the day-to-day reality of life on the frontline of the opioid crisis and advocates for each of us to find new ways to keep our communities safe and healthy.

Was 2017 really the "worst year ever," as some would have us believe? In his analysis of recent data on homicide, war, poverty, pollution and more, psychologist Steven Pinker finds that we're doing better now in every one of them when compared with 30 years ago. But progress isn't inevitable, and it doesn't mean everything gets better for everyone all the time, Pinker says. Instead, progress is problem-solving, and we should look at things like climate change and nuclear war as problems to be solved, not apocalypses in waiting. "We will never have a perfect world, and it would be dangerous to seek one," he says. "But there's no limit to the betterments we can attain if we continue to apply knowledge to enhance human flourishing."

Digital creator Dylan Marron has racked up millions of views for projects like "Every Single Word" and "Sitting in Bathrooms With Trans People" -- but he's found that the flip side of success online is internet hate. Over time, he's developed an unexpected coping mechanism: calling the people who leave him insensitive comments and asking a simple question: "Why did you write that?" In a thoughtful talk about how we interact online, Marron explains how sometimes the most subversive thing you can do is actually speak with people you disagree with, not simply at them.

To make accountability the norm after gender violence in the United States, we need to change tactics, says victims' rights attorney and TED Fellow Laura L. Dunn. Instead of going institution by institution, fighting for reform, we need to go to the Constitution and finally pass the Equal Rights Amendment, which would require states to address gender inequality and violence. By ushering in sweeping change, Dunn says, "our legal system can become a system of justice, and #MeToo can finally become 'no more.'"

Above all, she asks us to take a cue from the student activists at her school, survivors whose work for change has moved millions to action. "They shouldn't have to do this on their own," Wolk-Rogers says. "They're asking you to get involved."

When we talk about greenhouse gases, carbon dioxide gets the most attention -- but methane, which often escapes unseen from pipes and wells, has a far greater immediate impact on global warming.

On any given night, more than 450,000 people in the United States are locked up in jail simply because they don't have enough money to pay bail. The sums in question are often around $500: easy for some to pay, impossible for others. This has real human consequences -- people lose jobs, homes and lives, and it drives racial disparities in the legal system. Robin Steinberg has a bold idea to change this. In this powerful talk, she outlines the plan for The Bail Project -- an unprecedented national revolving bail fund to fight mass incarceration.

In the early days of digital culture, Jaron Lanier helped craft a vision for the internet as public commons where humanity could share its knowledge -- but even then, this vision was haunted by the dark side of how it could turn out: with personal devices that control our lives, monitor our data and feed us stimuli. (Sound familiar?) In this visionary talk, Lanier reflects on a "globally tragic, astoundingly ridiculous mistake" companies like Google and Facebook made at the foundation of digital culture -- and how we can undo it. "We cannot have a society in which, if two people wish to communicate, the only way that can happen is if it's financed by a third person who wishes to manipulate them," he says.

Because humanity's story, he reminds us, is a story of migration: "There are no restrictions that could ever be so rigorous to stop the wave of migration that has determined our human history," he says.
