More and more women in the United States are saying no to motherhood. In 2023, the U.S. fertility rate reached the lowest number on record. But the idea of non-motherhood is actually not a new phenomenon, nor did it come out of the modern feminist movement. For centuries, women have made choices about limiting births and whether or not to become mothers at all. This history is documented in a new book, "Without Children: The Long History of Not Being a Mother," by University of Chicago Assistant Instructional Professor Peggy O'Donnell Heffington.
Heffington writes about the historic trends of non-motherhood as well as the modern factors that are playing a role in women's choices to not have children today — from lack of structural support in the workplace, to a national law for paid maternity leave, and the sheer lack of affordability. She writes that if these trends continue, American millennials could become the largest childless cohort in history.

Deep beneath the ice of Antarctica and high above its frozen expanse, University of Chicago astrophysicist Abby Vieregg is hunting for neutrinos—some of the most elusive particles in the universe. Often called "ghost particles," these tiny messengers travel across billions of light-years, passing right through ordinary matter unnoticed. She is among the many scientists hunting for high-energy neutrinos—an area of research that was awarded the 2026 Nobel Prize in Physics.
What if your thoughts could allow you to feel the texture of an object, type a message or move a robotic arm? How does the brain translate thought into physical movement, and can technology bridge the gap for paralyzed patients, whose pathways are broken?
For decades, traditional cancer treatments like chemotherapy and radiation have targeted tumors directly—often with severe side effects and mixed results. But what if the key to treating cancer was already inside our bodies?
What makes a good life? For decades, psychologists have debated whether true fulfillment comes from happiness—a life of comfort and joy—or meaning—a life of purpose and impact. But what if there's a third way?
What if the secret to restoring your focus, improving your mental health, and even reducing crime rates wasn’t found in an app or a pill, but in a tree? In this episode, we speak with University of Chicago psychologist Marc Berman, whose research on “soft fascination” and nature’s cognitive effects is reshaping how we think about everything from urban planning to depression treatment. From groundbreaking hospital studies to surprising results with plastic plants, Berman’s work uncovers the deep—and often invisible—power that natural environments hold over our minds and bodies. Whether you're a city planner, a parent, or just someone feeling mentally fatigued, this conversation may just change the way you think about a walk in the park.
