In this performance, Sarah Jones brings you to the front row of a classroom in the future, as a teacher plugs in different personas from the year 2016 to show their varied perspectives on sex work. As she changes props, Jones embodies an elderly homemaker, a “sex work studies” major, an escort, a nun-turned-prostitute and a guy at a strip club for his bachelor party. It’s an intriguing look at a taboo topic, that flips cultural norms around sex inside out.

For six months, Suki Kim worked as an English teacher at an elite school for North Korea's future leaders -- while writing a book on one of the world's most repressive regimes.

How do babies learn so much from so little so quickly? In a fun, experiment-filled talk, cognitive scientist Laura Schulz shows how our young ones make decisions with a surprisingly strong sense of logic, well before they can talk.

Bill Gross has founded a lot of startups, and incubated many others -- and he got curious about why some succeeded and others failed. So he gathered data from hundreds of companies, his own and other people's, and ranked each company on five key factors.

Jeffrey Brown started out as a bewildered young pastor watching his Boston neighborhood fall apart around him, as drugs and gang violence took hold of the kids on the streets.

Infidelity is the ultimate betrayal. But does it have to be? Relationship therapist Esther Perel examines why people cheat, and unpacks why affairs are so traumatic: because they threaten our emotional security. In infidelity, she sees something unexpected — an expression of longing and loss. A must-watch for anyone who has ever cheated or been cheated on, or who simply wants a new framework for understanding relationships.

Chimpanzees are people too, you know. Ok, not exactly. But lawyer Steven Wise has spent the last 30 years working to change these animals' status from "things" to "persons." It's not a matter of legal semantics; as he describes in this fascinating talk, recognizing that animals like chimps have extraordinary cognitive capabilities and rethinking the way we treat them -- legally -- is no less than a moral duty.
