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.

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.

We chronicle the epic struggle to get drugs that treat very rare diseases on the market, and the unintended consequence of that fight, which affected the cost of all kinds of drugs. This is a strange story that involves a hit 70s TV show, a fake march on Washington, a courageous advocate, a carnival concessions wholesaler, and a new drug law that helped a lot of people, made drug companies billions of dollars, and opened a whole can of worms.

It’s hard to overstate just how important record album art was to music in the days before people downloaded everything. Visuals were a key part of one's experience with a record or tape or CD. The design of the album cover created a first impression of what was to come. Album art was certainly important to reporter Sean Cole, one particular album by one particular band: Devo. This is the story of Devo’s first record and the fight over the arresting image of a flashy, handsome golf legend on the cover. Plus, Katie Mingle gets the backstory of the Langley Schools Music Project LP, a haunting and uplifting outsider artist masterpiece.
