Why do girls feel empowered to engage in sexual activity but not to enjoy it? For three years, author Peggy Orenstein interviewed girls ages 15 to 20 about their attitudes toward and experiences of sex. She discusses the pleasure that's largely missing from their sexual encounters and calls on us to close the "orgasm gap" by talking candidly with our girls from an early age about sex, bodies, pleasure and intimacy.

Gutsy girls skateboard, climb trees, clamber around, fall down, scrape their knees, get right back up -- and grow up to be brave women.

MIT grad student Joy Buolamwini was working with facial recognition software when she noticed a problem: the software didn't recognize her own face -- because the people who coded the algorithm hadn't taught it to identify a range of skin tones and facial structures. In this eye-opening talk, hear about the need for accountability in algorithms (as they take over more and more aspects of our lives). Watch »

For many previous centuries (and for many reasons), creative storytelling has generally come from men, and from a male perspective. As director Jude Kelly points out, there's a more useful, more inclusive way to look at the world, and she calls on artists -- women and men -- to paint, draw, write about, film and imagine a gender-equal society. Watch »

John Koenig loves finding words that express our unarticulated feelings -- like "lachesism," the hunger for disaster, and "sonder," the realization that everyone else's lives are as complex and unknowable as our own. Here, he meditates on the meaning we assign to words and how these meanings latch onto us. Watch »

Quote of the Week

“

It's easy in this political and global economy to want to give up. We can easily resign to the thinking that government is too inefficient, too corrupt, unfixable. But just because a system is sick doesn't mean it's dying.

In the end, what really makes a government healthy is when healthy cells — that's you and I — get to the ground, roll up our sleeves, refuse to be helpless."
