In the early 1950s, teenage students in Lake County, Indiana, got up from their desks, marched down the halls and lined up at stations. There, fingers were pricked, blood was tested and the teenagers were sent on to the library, where they waited to get a specialized tattoo. Each one was in the same place on the torso, just under the left arm, and spelled out the blood type of the student. This experimental program was called Operation Tat-Type. It was administered by the county and the idea was simple: to make it easier to transfuse blood after an atomic bomb. At the age of 16, producer Liza Yeager's grandmother, who went to school in Lake County, was permanently marked in anticipation of a nuclear catastrophe.

Magic: The Gathering is a card game and your goal is to knock your opponent down to zero points. But Magic: The Gathering also has a deep mythology about an infinite number of parallel worlds. Eric Molinsky of Imaginary Worlds looks at why this handheld card game has survived the onslaught of competition from digital games, and how the designers at Wizards of the Coast create a sense of story and world-building within a non-sequential card game.

Juan de Oñate is one of the world’s lesser-known conquistadors, but his name can be found all over New Mexico. There are Oñate streets, Oñate schools, and, of course, Oñate statues. When an activist group removed one foot off an Oñate statue in 1998, they said it was a symbolic act meant to highlight the atrocities Oñate committed against the indigenous population. Just as people in New Mexico were learning more of this history, the city of Albuquerque was considering building yet another statue of him. This resulted in a years long conflict about how New Mexico should commemorate a “founding father” who committed such cruel acts.

After Toronto unveiled its "raccoon-resistant" compost bins in 2016, some people feared the animals would be starved, but many more celebrated the innovative design. Rolling out this novel locked bin opened a new battlefront in city's ongoing "war on raccoons." Journalist Amy Dempsey was researching the bins and raccoon behavior when her reporting took an unexpected turn down her own garbage-strewn alleyway.

The new film “Green Book” is rolling out across the country. I have not seen the film, so I can’t speak to its merits or shortcomings, but while people are possibly being introduced to the concept of the Green Book for the first time, we thought we’d re-release this story from a few years ago about the origin and significance of the Green Book: the Negro Motorists’ Travel Guide to the segregated US. As a special bonus to our story, we also have a Green Book story from Nate DiMeo of the memory palace. Nate had coincidentally written his episode called “Open Road” and we both released them without having heard the other. I think hearing them one after the other is real treat.
