Science Diction - Umami: A Century Of Disbelief
play

08/18/20 • 20 min

Salty, sweet, sour, bitter. Scientists once thought these were the only tastes, but in the early 20th century, a Japanese chemist dissected his favorite kombu broth and discovered one more: umami. In recent years, umami has become a foodie buzzword, but for nearly a century, the Western world was in full-blown umami denial—didn’t believe it existed. And we might have stayed that way if it weren’t for our most notorious and potent source of umami: MSG.

Science Diction - Lunacy: Mind Control From The Sky
play

02/16/21 • 15 min

On December 5th, 2012, a bill landed on President Barack Obama’s desk, meant to do one thing: remove the word “lunatic” from the federal code. This is because in 2012, you could still find the word in laws about banking and controlling estates, among others. And not only was it offensive, it was antiquated—ancient, in fact. The word lunacy comes from luna—Latin for moon. This is because there was a time when we thought the power to change our moods and minds came from the sky.

Guests:

Miena Hall is a Family Medicine Resident at Adventist Hinsdale Hospital.

Jo Marchant is a science journalist and author of The Human Cosmos.

Footnotes & Further Reading:

For a deep history on “madness,” check out Madness in Civilization: A Cultural History of Insanity, from the Bible to Freud, from the Madhouse to Modern Medicine by Andrew Scull. Meta-analyses and literature reviews haven’t backed up a lunar effect on human behavior, but more recent studies have found intriguing patterns.

Science Diction - Alcohol: History's Favorite Mind-Bending Substance
play

03/02/21 • 17 min

Vervet monkeys steal it out of people's hands. Chimpanzees in Guinea are known to climb up palm trees and drink it. There’s even a theory that loving it was an important adaptation for our pre-human ancestors, that the smell of fermentation helped them track down very ripe, calorie-rich fruit.

Alcohol has been deeply ingrained in our lives from the beginning, possibly since before we were human. And while the drive to drink is older than civilization, many have worked hard to reign it in. In 1920s America, these desires clashed like never before. It’s a story of a battle between chemists, and the unthinkable lengths the U.S. government went to to try to pry away our favorite mind-altering substance.

Guest:

Deborah Blum is a science writer and journalist.

Science Diction - Robot: Making A Mechanical Mind
play

02/23/21 • 15 min

In 1920, a Czech writer was stumped. He’d written a play about a future where machines that looked like people do our bidding. They were the perfect workers: obedient, hard working, and never demanded a pay raise. But what was the writer to call these marvelous machines? There wasn’t yet a word for this type of creation.

He had initially chosen labori, from the Latin for labor, but something about the word wasn’t quite right. It seemed...stiff, bookish. This play wasn’t just about machines who labored. It was about machines we exploited, relentlessly. And eventually, the writer landed on a word that fit better: R obot.

Robot comes from an old Czech word for drudgery and servitude. Though in his play - like so very many robo-dystopias to come - the writer showed that a mind we create to serve us, isn’t necessarily a mind we can control.

Footnotes & Further Reading:

See more drawings and diagrams in The Book of Knowledge of Ingenious Mechanical Devices by Ismail al-Jazari.

Check out some old footage of Unimate, the first worker robot.

Science Diction - Hydrox: How A Cookie Got A Name So Bad
play

10/16/20 • 20 min

The first Oreo rolled out of Chelsea Market in Manhattan in 1912, but despite the cookie’s popularity today, Oreos weren’t an immediate cookie smash hit. In fact, there was already another cookie on the block that looked remarkably similar to Oreos: two chocolate wafers embossed with laurel leaves, and white cream in the center. This cookie was widely loved, made with the highest quality ingredients, and saddled with a curious name: Hydrox.

So how did a cookie get a name so bad? Producer Alexa Lim takes us all the way back to the early 1900s, and brings us a story of the rise - and the crumble - of a cookie named Hydrox.

Guests:

Carolyn Burns is the owner of The Insight Connection, and a former marketing director for Keebler.

Stella Parks is a pastry chef and the author of Brave Tart: Iconic American Desserts.

Ellia Kassoff is the CEO of Leaf Brands.

Footnotes & Further Reading:

Science Diction - Mercury: How It Made Cats Dance
play

03/09/21 • 16 min

In 1953, in the coastal town of Minamata in Japan, locals noticed some cats were acting strangely—twitching, spinning in circles, almost dancing. The reality was far darker. What looked like dancing was really convulsions. The cats drooled, spun in circles, and flung themselves into the sea. The cause of this strange behavior, residents discovered, was mercury.

Mercury—a silvery liquid, named for a quick-footed Roman God—has captivated humans since ancient times. It’s found in Egyptian tombs that date to 1500 BCE, and the first emperor of unified China believed it was the elixir of life. But what happens when it invades a town, and seeps into our brains?

Footnotes & Further Reading:

For this story, we relied heavily on the book Minamata : Pollution and the Struggle for Democracy in Postwar Japan.Learn how mercury played a pivotal role in pinpointing a key campsite location in the Lewis and Clark expedition.

This episode of Science Diction was written by Kaitlyn Schwalje, and produced by Elah Feder and Johanna Mayer. Elah is our editor and senior producer.

Science Diction - Spanish Flu

Spanish Flu

Science Diction

play

04/28/20 • 16 min

In the fall of 1918, Philadelphia newspapers announced that a new virus had arrived in the city, the so-called “Spanish flu.” But the facts and scope were muddy and uncertain, and the city decided to push forward with a highly-anticipated parade. About 200,000 people showed up, and packed onto sidewalks.

Halfway across the country, St. Louis, Missouri looked very different that fall. Businesses shuttered, movie theatres went dark, and students stayed home.

Just like today, cities across the U.S. responded to the 1918 influenza pandemic differently—with very different results.

In this episode, we go back to 1918 and a pandemic which wasn’t Spanish at all.

Footnotes And Further Reading:

Get into the nitty gritty of viral evolution with "1918 Influenza: the Mother of All Pandemics” which reviews the 1918 pandemic and all outbreaks it later spawned.

The CDC’s Pandemic Influenza Storybook paints a vivid picture of life during the pandemic.

We first learned about Philadelphia’s Liberty Loan Parade from the Washington Post’s reporting.

For this story, we read many old articles from newspapers across the country, all archived on newspapers.com (available with a subscription).

Credits:

Science Diction is hosted and produced by Johanna Mayer. Our producer and editor is Elah Feder. We had additional story editing from Nathan Tobey, and fact checking help from Michelle Harris. Our composer is Daniel Peterschmidt. We also included audio from "The Liberty Loan March," performed by the United States Marine Band, which is in the public domain. Special thanks to Alan Kraut, a professor of history at American University who’s written extensively on the topic of immigration, disease, and prejudice. And to Chris Naffziger, who spoke to us about St. Louis’s response to the 1918 pandemic. You can read more of his reporting for St. Louis Magazine.
