Curious City - Deconstructing The Chicago-Style Hot Dog

Chicago-style hot dogs are a beloved culinary masterpiece: A snappy all-beef wiener, steamed poppy seed bun, yellow mustard, chopped onions, neon-green relish, two slices of tomato, a dill pickle spear, two sport peppers and a final whoosh of celery salt.

But how did that unique mix of ingredients come to be? In a special Curious City presentation, Chicago’s premier hot dog expert breaks down the history of each ingredient. It’s a tale of immigration to Chicago’s Maxwell street neighborhood a century ago. Click here for the full story.

50 Things That Made the Modern Economy - Robot

Robots threaten the human workforce, but their ubiquity and growing competence make them crucial to the modern economy. In 1961 General Motors installed the first Unimate at one of its plants. It was a one-armed robot resembling a small tank that was used for tasks like welding. Now, as Tim Harford explains, the world’s robot population is expanding rapidly (the robot “birth rate” is almost doubling every five years) and, coupled with rapid advances in artificial intelligence, robots are changing the world of work in unexpected ways.

CrowdScience - Can Trees Help us Fight Air Pollution?

Trees take in carbon dioxide but they also convert some of the toxic gases in our air. How much help can trees give us in fighting air pollution and could where we plant them make an even bigger difference? Crowdscience reports from the side of some busy roads on how canopy coverage may be part of the answer. At a lab in Louisiana one scientist is putting oak leaves through their paces to find out how effective they are at cleaning our air.

Amicus With Dahlia Lithwick | Law, justice, and the courts - Never Mind

On Monday, the Department of Justice announced an abrupt about-face on voting rights, essentially walking away from a lawsuit against a harsh voter-ID law in Texas. We discuss the reversal and its implications with Janai Nelson of the NAACP Legal Defense and Educational Fund. She was one of the lawyers in the strange position of arguing the case in court this week, the day after the DOJ reversed course.

We also sit down with Jeffrey Fisher, who argued an important immigration-related case at the Supreme Court his week. Esquivel-Quintana v. Sessions asks whether a legal immigrant can be deported for something that counts as a serious crime in some states, but not others. It also previews a question likely to play a big role in Neil Gorsuch’s confirmation hearings: how much deference courts should give federal agencies when interpreting the meaning of laws.
