Social Infrastructure is the glue that binds communities together, and it is just as real as the infrastructure for water, power, or communications, although it's often harder to see. But Eric Klinenberg says that when we invest in social infrastructures such as libraries, parks, or schools, we reap all kinds of benefits. We become more likely to interact with people around us, and connected to the broader public. If we neglect social infrastructure, we tend to grow more isolated, which can have serious consequences.

Cartoon sound effects are some of the most iconic sounds ever made. Even modern cartoons continue to use the same sound effects from decades ago. How were these legendary sounds made and how have they stood the test of time?

The tradition of the Tomb of the Unknowns goes back only about a century, but it has become one of the most solemn and reverential monuments. When President Reagan added the remains of an unknown serviceman who died in combat in Vietnam to the Tomb of the Unknowns in Arlington National Cemetery in 1984, it was the only set of remains that couldn’t be identified from the war. Now, thankfully, there will never likely be a soldier who dies in battle whose body can’t be identified. And as a result of DNA technology, even the unknowns currently interred in the tomb can be positively identified. The Known Unknown

Frank Lloyd Wright changed the field of architecture, and not just through his big, famous buildings. Before designing many of his most well-known works, Wright created a small and inexpensive yet beautiful house. This modest home would go on to shape the way working- and middle-class Americans live to this day. Usonia Redux This episode is a recut combination of episodes 246 & 247

In the 1950s, Los Angeles was an up-and-coming city but wasn’t quite there yet. City leaders were looking for a way to boost Los Angeles's profile as a world class city and also give Angelenos something to rally behind. They believed that what L.A. really needed was a baseball team. They picked Chavez Ravine, near downtown LA, as the perfect home for a perfect new stadium, but the land had been home to a vibrant community of Mexican and Mexican American families for decades.

Where does your recycling go? In most places in the U.S., you throw it in a bin, and then it gets carted off to be sorted and cleaned at a Materials Recovery Facility (MRF). From there, much of it is shipped off to mills, where bales of paper, glass, aluminum, and plastic are pulped or melted into raw materials. Some of these mills are here in the U.S. And once upon a time, many of them were in China. Since 2001, China was one of the biggest buyers of American recycling.  That is, until last year, when China pulled a move that no one saw coming: they stopped buying. National Sword

Here at 99% Invisible, we think about color a lot, so it was really exciting when we came across a beautiful book called The Secret Lives of Color by Kassia St. Clair It’s this amazing collection of stories about different colors, the way they’ve been made through history, and the lengths to which people will go to get the brightest splash of color.

In May of 1990, law enforcement raided a warehouse in Douglas, AZ and a private home across the border in Agua Prieta, Mexico. Connecting the two buildings, they found a tunnel, more sophisticated than anything anyone had seen before. The tunnel in Douglas became a kind of prototype for many tunnels afterwards and a hallmark of the Sinaloa Cartel. The Tunnel

Santa Barbara, California, is a famously beautiful place, but if you look offshore from one of the city's many beaches, you'll see a series of artificial structures that stand out against the natural blue horizon. These oil platforms are at the center of a complicated debate going on right now within the environmental community about the relationship between nature and human infrastructure.

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. Atomic Tattoos

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.
