Building a pandemic-free future won't be easy, but Bill Gates believes that we have the tools and strategies to make it possible -- now we just have to fund them. In this forward-looking talk, he proposes a multi-specialty Global Epidemic Response and Mobilization (GERM) team that would detect potential outbreaks and stop them from becoming pandemics. By investing in disease monitoring, research and development as well as improved health systems, Gates believes we can "create a world where everyone has a chance to live a healthy and productive life -- a life free from the fear of the next COVID-19."

Women and girls are conditioned to believe success is "a seat at the table." Creator, actress and author Lilly Singh thinks we need to build a better table.

What can't Candace Parker do? A two-time NCAA champion, two-time Olympic gold medalist and two-time WNBA champion, Parker knows what it takes to fight for your dreams. In this inspiring talk, she shares what she's learned during a career spent not accepting limits -- and how her daughter taught her the best lesson of all. "Barrier breaking is about not staying in your lane and not being something that the world expects you to be," she says. "It's about not accepting limitations."

"You are constantly becoming a new person," says journalist Shankar Vedantam.

The secret behind medicine that uses messenger RNA (or mRNA) is that it "teaches" our bodies how to fight diseases on our own, leading to groundbreaking treatments for COVID-19 and, potentially one day, cancer, the flu and other ailments that have haunted humanity for millennia. RNA researcher Melissa J. Moore -- Moderna's chief scientific officer and one of the many people responsible for the rapid creation and deployment of their COVID-19 vaccine -- takes us down to the molecular level, unraveling how mRNA helps our bodies' proteins maintain health, prevent disease and correct errors in our genetic code. "We have entered an entirely new era of medicine," Moore says.

There's a mistaken belief in today's working world that leaders need to be serious all the time to be taken seriously. The research tells a different story.

After more than two decades as an anchor for ABC News, an on-air panic attack sent Dan Harris's life in a new direction: he became a dedicated meditator and, to some, even a guru. But then an anonymous survey of his family, friends and colleagues turned up some brutal feedback -- he was still kind of a jerk. In a wise, funny talk, he shares his years-long quest to improve his relationships with everyone (starting with himself) and explains the science behind loving-kindness meditation, and how it can boost your resiliency, quiet your inner critic and simply make you more pleasant to be around.
