Conventional vaccine testing is a slow, years-long process. As thousands of people continue to die each day from COVID-19, bioethicist Nir Eyal proposes a radical idea that could dramatically accelerate the vaccine development timeline: "human challenge trials," in which scientists would deliberately expose volunteers to the virus to more quickly determine a vaccine's efficacy. (This virtual conversation, hosted by head of TED Chris Anderson, was recorded June 15, 2020.)

"I was the first woman president of an African nation, and I do believe more countries ought to try that," says H.E. Ellen Johnson Sirleaf, Nobel laureate and former president of Liberia. Telling the story of how Liberian women helped rebuild their country after years of civil war, Sirleaf discusses why gender equality is essential to peace and prosperity -- and shares her plan to uplift a generation of women prepared to take leadership positions and catalyze social change.

How do you end a story? Host of "Radiolab" Jad Abumrad tells how his search for an answer led him home to the mountains of Tennessee, where he met an unexpected teacher: Dolly Parton.

Legendary hip-hop producer Swizz Beatz is on a mission to revolutionize the way artists do business. In this glorious talk, he shares some of the ways he's helping fellow creatives thrive, including a roving art fair that gives artists 100 percent of their sales, a new commission system for galleries to fund living visual artists and Verzuz, online musical celebrations that bring joy to fans -- and sales to musicians. "If we're not protecting the arts, we're not protecting our future," he says.

In the US, mascots are used to pump up crowds at sporting events, or for traumatizing generations of children at Chuck E. Cheese, but in Japan it’s different. There are mascots for towns, aquariums, dentists' offices, even prisons. There are mascots in cities that tell people not to litter, or remind them to be quiet on the train. Everything has a mascot and anything can be a mascot. The reason why mascots and character culture flourish in Japan is connected with the nation’s fascinating history with mythical monsters known as Yokai.

Colonialism remains an inescapable blight on the present, lingering in the toxic, internalized mythologies and stereotypes that have outlived the regimes that created them, says historian Farish Ahmad-Noor. Examining why these prejudices and narratives persist (and sometimes thrive), he suggests a multidisciplinary approach to reject cultural obsessions with romanticized history and prevent this nostalgia from perpetuating past oppressions.

Baratunde Thurston explores the phenomenon of white Americans calling the police on black Americans who have committed the crimes of ... eating, walking or generally "living while black." In this profound, thought-provoking and often hilarious talk, he reveals the power of language to change stories of trauma into stories of healing -- while challenging us all to level up.

Our brains create categories to make sense of the world, recognize patterns and make quick decisions. But this ability to categorize also exacts a heavy toll in the form of unconscious bias. In this powerful talk, psychologist Jennifer L. Eberhardt explores how our biases unfairly target Black people at all levels of society -- from schools and social media to policing and criminal justice -- and discusses how creating points of friction can help us actively interrupt and address this troubling problem.

What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus -- a 77-million-year-old sauropod that was as tall as a two-story house and as heavy as a jumbo jet -- and considers how amazingly improbable it is that a tiny mammal living in the cracks of the dinosaur world could evolve into a sentient being capable of understanding these magnificent creatures. Join him in a celebration of the Earth's geological history and contemplate our place in deep time.

If you’re on Instagram, there’s a decent chance you’ve seen a picture of one particular building called the Yardhouse. It was designed by the London-based architecture collective Assemble. The design of the building had a lot to say about creating spaces that were functional, collaborative, and inexpensive. But people on Instagram mainly saw a pretty wall to serve as the backdrop to their photos. Instagram and architecture have formed a symbiosis and the consequences of them interacting and feeding back on each other are still playing out.
