Would you swallow a micro-robot? In a gutsy demo, physician Vivek Kumbhari navigates Pillbot, a wireless, disposable robot swallowed onstage by engineer Alex Luebke, modeling how this technology can swiftly provide direct visualization of internal organs. Learn more about how micro-robots could move us past the age of invasive endoscopies and open up doors to more comfortable, affordable medical imaging. (This talk contains medical imagery.)

As a self-proclaimed radical street librarian, Storybook Maze makes books appear where they're scarce. Through initiatives like free, public book vending machines and street corner story times, she eliminates book deserts — or areas with limited access to literature — by making books accessible for children in underserved communities. (And in case you're wondering, she shares how you can become a radical street librarian, too.)

Agriculture fundamentally changed the way humans live — but at a cost, using up huge tracts of land and wreaking havoc on the environment, even as millions still go hungry. Entrepreneur and investor David Friedberg paints a picture of the evolution of agriculture and introduces a scientific breakthrough — "boosted breeding" — that might just transform how the world produces food. (This conversation was recorded live with head of TED Chris Anderson.)

The way we raise animals is destructive to humans, animals and the environment, says cardiologist and entrepreneur Uma Valeti. He presents a solution that doesn't require you to give up your favorite protein-packed meals: cultivated meat, grown directly from animal cells. Reportedly some of the "most chicken-y chicken" you'll taste, Valeti envisions how such cultivated meat could save billions of animal lives, improve human health and help protect our planet.

Family life often requires extraordinary bravery, from navigating the daily challenges to surviving the unexpected crises. Author and podcaster Kelly Corrigan offers profound wisdom (and seven key words) to help you focus in on what matters most.

Justin Trudeau has served as the prime minister of Canada since 2015. There's a lot to dig into from his years in office — and from his life before, as well. He sits down with organizational psychologist Adam Grant to discuss lessons learned about leadership and how he navigated early struggles with impostor syndrome. He also shares his approach to maintaining motivation in the face of disapproval and criticism, how he encourages people to speak truth to power, why he considered quitting and what keeps him awake at night. (This interview was recorded for the "ReThinking with Adam Grant" podcast.)
