On the Media: American Emergency
This Radiolab episode explores the turbulent history and existential crisis of the Federal Emergency Management Agency (FEMA), revealing how a mission rooted in helping Americans during disasters has become entangled in political paranoia, bureaucratic dysfunction, and national fear. Through excerpts from On the Media’s investigative series, the story traces FEMA’s evolution from Cold War civil defense to post-Katrina reform, and into the present-day threat of abolition under a Trump-led administration.

Oliver Sipple
A single act of heroism by Oliver Sipple, a gay Vietnam veteran who thwarted an assassination attempt on President Gerald Ford, catapulted him into national fame—only for that fame to destroy his life when journalists outed him against his wishes, fracturing his family and leaving him isolated. The episode reveals how larger forces—press freedom, political agendas, and social movements—collided on the back of one vulnerable man.

This American Roach
This Radiolab episode follows reporter Alex Neason as she confronts her deep-seated fear and disgust toward cockroaches, embarking on a journey that evolves from personal phobia into a profound exploration of history, race, class, and the human tendency to vilify animals we label as 'pests.' What begins as a quest to overcome a visceral reaction becomes a reckoning with how societal failures shape our relationship with nature.

Worth
This Radiolab episode, originally from 2014 and resurfaced for its enduring relevance, explores the moral, economic, and emotional challenges of assigning monetary value to life, death, and nature. It asks how society decides what is worth paying for — whether a cancer drug, a drone strike condolence payment, or the services of an ecosystem — and reveals how these valuations shape policy, ethics, and human dignity.

The Bad Show

What is a Pig Worth?
This Radiolab episode follows animal rights activist Wayne Hsiung’s 2017 direct action at a Smithfield Foods pig farm, where he and his group, Direct Action Everywhere (DxE), rescued two ailing piglets, Lily and Lizzie. His subsequent trial in Utah becomes a legal and moral crucible, forcing jurors to confront the unsettling question: what is the value of an animal in the eyes of the law? The case ends in acquittal, not because the law changed, but because the jury was forced to reckon with the dissonance between economic value and moral worth.

Forests on Forests
This Radiolab episode explores the hidden world of forest canopies, revealing that trees host entire ecosystems high above the ground, complete with soil, plants, animals, and even aquatic creatures — a realm as rich and complex as the forest floor. Ecologist Nalini Nadkarni’s pioneering work in the 1980s uncovered canopy soils teeming with life, while later research by Karina Mifune showed these aerial soils are nutrient-rich, offering trees a vital resource during times of scarcity below.
