How a Missouri Supreme Court ruling triggered clash between justices and state lawmakers
Judges and lawmakers are clashing in Missouri, and it all has to do with a unanimous ruling delivered last week by the state Supreme Court. On this episode of the Legal Roundtable, our panel of legal experts unpacks the drama over the court’s decision to strike down a law that allowed the secretary of state to rewrite ballot summaries. In response, the law’s sponsor called the justices “little kings and queens in their black robes.” In addition to that case, our panel also analyzes major developments in the state’s ban on trangender healthcare, a trial over abortion restrictions, a developer suing over lost profits, and more.

How a St. Louis-based newspaper helped ignite the spark that led to the Mexican Revolution
In 1905, Mexican journalist Ricardo Flores Magón escaped the Porfiriato dictatorship and settled in St. Louis, where he launched the newspaper Regeneración. With 20,000 readers throughout Mexico and the U.S., the leftist publication raised awareness of growing wealth inequality, labor exploitation and political corruption in both countries. Historian Francisco Perez shares how Flores Magón connected the struggles of the American working class with that of the Mexican working class, how St. Louis' labor movement shaped Flores Magón’s worldview, and why, more than a century later, the activist’s politics still resonate.

Missouri’s prison population is at a 20-year low. But prison deaths have never been higher
The number of people incarcerated in Missouri prisons is lower than it has been in decades; yet, recent years have seen record-high deaths among those in custody. The deaths reflect an ongoing crisis behind the walls of the state's correctional institutions, say activist ML Smith, founder of the Missouri Justice Coalition, and Rika White, criminal justice policy manager at Empower Missouri. Smith and White take us inside their role in a notable Jan. 14 Missouri House Corrections Committee hearing that featured pointed questions for Trevor Foley, director of the Missouri Department of Corrections, about the state of healthcare inside the state’s 19 prisons.

How a WashU professor used concrete to build a 20-foot-tall home for migratory birds
A 20-foot-tall concrete spiral was recently completed at the Audubon Center at Riverlands nature reserve near St. Louis. The structure's practical use will be as a bird blind — a temporary home for migratory birds. But there’s something else that’s fascinating about this structure: A novel method of shaping concrete. To get to the bottom of this spiral (and inside its concrete walls) we talk with Pablo Moyano Fernández, associate professor of architecture at WashU’s Sam Fox School of Design & Visual Arts. Moyano Fernández is the creator of that structure, called "Avis Spiralis."

New book explains why Missouri and Illinois prairies vanished
The American prairie once stretched across Missouri and Illinois, a vast grassland teeming with wildlife and rich biodiversity. Today, less than 1% of that prairie remains — disappearing even faster than the Amazon rainforest. In this encore presentation, environmental journalists Dave Hage and Josephine Marcotty discuss how prairies were destroyed, why their loss is one of the world’s greatest ecological disasters, and what it will take to bring it back. Hage and Marcotty are authors of the new book, “Sea of Grass: The Conquest, Ruin and Redemption of Nature on the American Prairie.”

Republican advocate for phasing out Missouri income tax says plan will spur growth
Governor Mike Kehoe’s plan to phase out Missouri’s income tax over five years — and replace much of the revenue with a sales tax on services — has sparked a heated debate. Supporters say it could boost population growth, while critics warn of higher costs and fiscal risks. One of the main proponents of eliminating the income tax is Sen. Ben Brown, a Republican from Washington, Missouri. Brown discusses the proposal on the Politically Speaking Hour on St. Louis on the Air.
