The age-old sharing economies of Africa -- and why we should scale them | Robert Neuwirth

From rides to homes and beyond, we're sharing everything these days, with the help of digital tools. But as modern and high-tech as the sharing economy seems, it's been alive in Africa for centuries, according to author Robert Neuwirth. He shares fascinating examples -- like apprenticeships that work like locally generated venture capital and systems for allocating scarce water -- and says that if we can propagate and scale these models, they could help communities thrive from the bottom up.

Scientists must be free to learn, to speak and to challenge | Kirsty Duncan

"You do not mess with something so fundamental, so precious, as science," says Kirsty Duncan, Canada's first Minister of Science. In a heartfelt, inspiring talk about pushing boundaries, she makes the case that researchers must be free to present uncomfortable truths and challenge the thinking of the day -- and that we all have a duty to speak up when we see science being stifled or suppressed.

The doctors, nurses and aid workers rebuilding Syria | Rola Hallam

Local humanitarians are beacons of light in the darkness of war, says humanitarian aid entrepreneur and TED Fellow Rola Hallam. She's working to help responders on the ground in devastated communities like Syria, where the destruction of health care is being used as a weapon of war. One of her campaigns achieved a global first: a crowdfunded hospital. Since it opened in 2017, the aptly named Hope Hospital has treated thousands of children. "Local humanitarians have the courage to persist, to dust themselves off from the wreckage and to start again, risking their lives to save others," Hallam says. "We can match their courage by not looking away or turning our backs."

A healthy economy should be designed to thrive, not grow | Kate Raworth

What would a sustainable, universally beneficial economy look like? "Like a doughnut," says Oxford economist Kate Raworth. In a stellar, eye-opening talk, she explains how we can move countries out of the hole -- where people are falling short on life's essentials -- and create regenerative, distributive economies that work within the planet's ecological limits.

The truth about unwanted arousal | Emily Nagoski

Sex educator Emily Nagoski breaks down one of the most dangerous myths about sex and introduces us to the science behind arousal nonconcordance: when there's a disconnect between physical response and the experience of pleasure and desire. Talking about such intimate, private moments can feel awkward or difficult, yet in this straightforward talk Nagoski urges all of us to share this crucial information with someone -- judges, lawyers, partners, kids. "With every brave conversation we have, we make the world that little bit better," says Nagoski. (This talk contains mature content.)
