Houseplants are having a moment right now. In 2020, 66% of people in the US owned at least one plant, and sales have skyrocketed during the pandemic. Meanwhile, Instagram accounts like House Plant Club have a million followers. Over the past decade there has been a steady stream of think pieces offering explanations for the emergence of this new obsession. But while millennials may have perfected the art of plant parenting, this is not the first time people have gotten completely obsessed with houseplants. Journalist Anne Helen Petersen digs into the history of domesticated plants in a series of articles on her Substack, Culture Study, and joins us to talk about what she's found.

99% Invisible producer emeritus Avery Trufelman traveled from New York to San Francisco recently, and took host Roman Mars to see an unusually shaped old building on the west side of the Bay. As it turns out, this peculiar octagonal home isn't unique -- there was a whole architectural fad of building these back in the mid 1800s, tapping into a parallel trend: self-improvement. Publisher Orson Fowler (most famous for being a phrenologist) used his professional position to self-publish a book about the many benefits, health and otherwise, of living in an octagonal home. His book, Octagon House: A Home For All, became a sensation. In its wake, hundreds of octagon houses started popping up all over the country.

Sakhalin is a long, skinny island east of Russia's mainland. Russia and Japan have long fought over the territory, which has left the ethnic Koreans who came to work on the island starting in the early 1900s in a kind of limbo. Tatyana Kim, a native of Sakhalin, guides us through its unusual history and the difficulties of a repatriation that is long overdue.

The Ojibwe name for wild rice is Manoomin, which translates to “the good berry.” The scientific name is Zizania palustris. It’s the only grain indigenous to North America, and while it might be called rice, it’s actually not closely related to brown or white rice at all. It has long played an important role in Ojibwe cultures, but last year, Manoomin took on a new role: plaintiff in a court case. Last August, the Minnesota Department of Natural Resources was sued by wild rice. The case of Manoomin v Minnesota Department of Natural Resources alleges that the Minnesota DNR infringed on the wild rice’s right to live and thrive. But can wild rice sue a state agency? The short answer is: yes. This is the story about what might happen if rice wins.

No teenager in America in the 1980s could avoid the gravitational pull of the mall, not even author Alexandra Lange. In her new book, Meet Me by the Fountain, Lange writes about how malls were conceptually born out of a lack of space for people to convene in American suburbs. Despite the fact indoor shopping malls are no longer in their heyday, malls have not gone away completely. Lange writes about the history of mall culture, and how the mall became a ubiquitous part of American life.

Priceless cultural artifacts have been plundered and sold for hundreds of years. You can find these relics in museums and in private collections. In recent years, with the advent of online marketplaces, researchers have begun to find a lot of artifacts for sale on the web. The Syrian War has resulted in hundreds of thousands of casualties. Not to mention, hundreds of billions in damages. And that battle has played out on land considered to be the cradle of civilization -- a place rich with layers of archeological history. Producer Zeina Dowidar and her team on the Kerning Cultures podcast tell stories about the Middle East and North Africa. For this episode, they took a comprehensive, inside look at how one country struggled to retain its cultural heritage in the midst of a brutal conflict.

In the late 1700s, a young man named Friedrich Froebel was on track to become an architect when a friend convinced him to pursue a path toward education instead. And in changing course, Froebel arguably ended up having more influence on the world of architecture and design than any single architect -- all because Friedrich Froebel created kindergarten. Frank Lloyd Wright’s son, John, was an architect, but his most famous creation wasn’t a building. It was a toy set that kids have been playing with for over 100 years.

Downtown Toronto has a dense core of tall, glassy buildings along the waterfront of Lake Ontario. Outside of that, lots short single family homes sprawl out in every direction. Residents looking for something in between an expensive house and a condo in a tall, generic tower struggle to find places to live. There just aren’t a lot of these mid-sized rental buildings in the city. And it's not just Toronto -- a similar architectural void can be found in many other North American cities, like Los Angeles, Seattle, Boston and Vancouver. And this is a big concern for urban planners -- so big, there's a term for it. The "missing middle." That moniker can be confusing, because it's not directly about middle class housing -- rather, it's about a specific range of building sizes and typologies, including: duplexes, triplexes, courtyard buildings, multi-story apartment complexes, the list goes on. Buildings like these have an outsized effect on cities, and cities without enough of these kinds of buildings often suffer from their absence.

Data is the lifeblood of public health, and has been since the beginning of the field. But essential data gathering for the COVID pandemic was hindered by a couple of of underlying weakness in the US public health apparatus. We have a fractured system where the power lies in US states that don't always coordinate effectively. Also there has been inconsistent funding. When there was an immediate crisis, there would be an infusion of cash. But then, when the crisis passed, the resources would evaporate. We take a look at data gathering in regards to public health from the 1600s to today and how it might change in the future.
