Smell this yogurt, is it still good? Our sense of smell has the ability to keep us healthy and safe. In fact in some cases, our ability to detect "off" foods using our sense of smell can be superior to dogs and other animals. Smell is often undervalued and yet capable of inspiring profound admiration if we stop turning our noses at it. Producer Annie Bender examines what we lose when we take our powerful — but often misunderstood — sense of smell for granted. *This episode originally aired on June 3, 2024.

For almost four years, the Bosnian War in the former Yugoslavia was characterized by ethnic hatreds, atrocities, and a refugee crisis. So when leaders of the warring factions were sequestered in an American air base and forced to come up with the 1995 peace agreement known as the Dayton Accord, the world was relieved. But is a cessation of violence the same as real peace? *This episode is the third in a five-part series called Inventing Peace.

Two hundred years ago, Wilhelm von Humboldt created the education system as we know it today. At the heart of his philosophy of education was the concept of Bildung — reaching one's inner potential. Yet over the years, as his public education system was adopted, Bildung may well have been the critical piece left out. *This episode is part one of two-part series. It originally aired on April 15, 2024.

The Wonderful Wizard of Oz was an instant bestseller in 1900. Thirty-nine more official Oz books followed, as well as other derivative works like Broadway musicals, films, comic books, cartoons, sitcom parodies and more. IDEAS follows the proverbial yellow brick road to uncover how this seemingly simple story of friendship, self reliance and longing for home continues to speak to us, 125 years after it was published.

When Israeli Prime Minister Yitzhak Rabin and Palestine Liberation Organization leader Yasser Arafat met in Washington to sign the first Oslo Accords in 1993, it was supposed to usher in a new era of peace and lay the groundwork for a more stable Middle East. Three decades later, the Accords are primarily remembered as a failure. Nahlah Ayed and guests discuss what went wrong, and what lessons the Oslo Accords hold for the future.
