Metaphors can help us understand complicated scientific concepts. But they can also have a downside. And, a pair of musicians wrote a concept album inspired by moths—and found that humans have more in common with the insects than they expected.How Metaphor Has Shaped Science, For Better Or WorseHere at Science Friday, we’re big fans of metaphors. They can make complicated scientific concepts easier to understand, for both non-experts and scientists themselves. For example, “the big bang” helps us visualize the beginning of the universe. Or we can understand DNA’s role better as a “building block of life.”But some of these scientific metaphors also have a downside, and can even set research back.Sam Harnett and Chris Hoff are the hosts of the podcast series “The World According to Sound,” and they sat down with Science Friday’s Director of News and Audio, John Dankosky, to talk about their new project, “An Inexact Science.” They discuss a special two-hour episode that explores how language and metaphor have shaped science, for better or worse.Intertwining The Lives Of Moths And Humans Through MusicBefore the pandemic, Peter Kiesewalter didn’t think much of moths. Like a lot of people, he’d thought of them mostly as pests. But when his brother Tobi, an interpretive naturalist for Ontario Parks and moth enthusiast, showed him macro photos he’d taken of them, he was blown away. “[They were] absolutely stunning,” Peter says. “The amount of colors and hair were just extraordinary.”Peter is a Grammy-nominated musician based in New York City. He’s composed music for ABC News, Monday Night Football, and even a “Winnie The Pooh” show. As COVID-19 spread in 2020, work for him and his partner Whitney La Grange, a professional violinist, dried up. So they hunkered down at the family cottage in Ottawa, Canada, along with Tobi’s family. Peter was looking for a new show idea, and when his brother opened up the world of moths to him, he was hooked. “I had to find a way to interpret moths artistically,” he said. “And I started to find connections between them and us.”That led to “The Moth Project,” a concept album and stage show that combines moth science and visuals with a whole ecosystem of musical genres: 80s pop, funk, classical, covers, even spoken word. Each song ties a stage of a moth’s life (emergence, flight, migration) to a universal human experience. But for Peter, a lot of these songs turned out to be far more personal than he initially thought.SciFri producer and host of our Universe of Art podcast D Peterschmidt sat down with Peter and Tobi Kiesewalter and Whitney La Grange to find out how this album came together and how understanding moths could better help us understand ourselves.Transcripts for each segment will be available after the show airs on sciencefriday.com.

On October 14, NASA launched Europa Clipper, its largest planetary mission spacecraft yet. It’s headed to Jupiter’s icy moon Europa, which could have a giant ocean of liquid water hidden under its icy crust. And where there’s water, scientists think there may be evidence of life. The spacecraft is equipped with nine different instruments and will complete nearly 50 flybys of Europa, scanning almost the entire moon.SciFri producer Kathleen Davis talks with Dr. Padi Boyd, NASA astrophysicist and host of the agency’s podcast “Curious Universe,” about the launch and the excitement at NASA. Then, Ira checks in with two scientists who are working on the mission about what they’re excited to learn: Dr. Ingrid Daubar, planetary scientist at Brown University and a Europa Clipper project staff scientist at NASA’s Jet Propulsion Laboratory; and Dr. Tracy Becker, planetary scientist at Southwest Research Institute and a deputy principal investigator for the ultraviolet spectrograph on the Europa spacecraft.Transcript for this segment will be available after the show airs on sciencefriday.com.

Two giant pandas on loan from China have arrived at the Smithsonian’s National Zoo. Also, originally from Central Asia, Kernza doesn’t need to be replanted every year, unlike crops such as corn and soybeans.Pandas Return To Washington, D.C., ZooOn Tuesday, two VIPs (Very Important Pandas) arrived at Washington’s Dulles International Airport, en route to new quarters at the Smithsonian’s National Zoo and Conservation Biology Institute.The arrival marks a new chapter of “panda diplomacy,” which leverages the public’s affection for the cute, charismatic animals to both strengthen US-China ties and fund conservation initiatives. Sophie Bushwick, senior news editor at New Scientist, joins SciFri’s John Dankosky to talk about the giant pandas’ arrival and other stories from the week in science.Scientists Push For A Lesser-Known Grain Called KernzaOn a recent weekday afternoon, dozens of people filled the cozy taproom at Blue Jay Brewing Company. On tap that day was a fresh creation called New Roots. The American Lager was a hit, with many of the patrons going back to the bar for another glass.Blue Jay’s owner and brewer, Jason Thompson, was also pleased with the result of this experimental beer, which he described as “earthy, almost nutty,” with a “lingering honey-like sweetness to it.” Those flavors came from his choice to use a novel grain called Kernza for 25% of the 600 pounds of grain needed for the whole brew, he said.Read the rest at sciencefriday.com.Transcripts for each segment will be available after the show airs on sciencefriday.com.

The Basics Of How Health Misinformation SpreadsHealth misinformation can circulate quickly on social media: false claims about vaccines, ads pushing suspicious-looking supplements, politicians making claims about contraception or abortion that don’t match the science.As November nears, Science Friday is spotlighting the science that’s shaping the election with a short series about health misinformation.Ira is joined by Irving Washington, senior vice president and executive director of the Health Misinformation and Trust Initiative at KFF, a nonprofit health policy research, polling, and news organization to provide a primer on the basics of health misinformation; how to identify it, emerging trends and the role of artificial intelligence.We want to hear from you! Is there a piece of health information that you’ve seen recently that you’re skeptical about? Fill out this form, email us a voice memo to scifri@sciencefriday.com, or leave us a voicemail at 1-646-767-6532.In the coming weeks we’ll select a couple of topics from our listeners to investigate with the help of a subject matter expert.Benjamin Franklin And The American Experiment Collide On StageWhen you think of famous scientists of the early United States, you likely think of Benjamin Franklin, inventor of the lightning rod, bifocal glasses, and even the glass harmonica.He and his son are the subject of the play “Franklinland.” It explores their sometimes contentious relationship, Benjamin Franklin’s accomplishments as a scientist, and how the scientific method can be used to understand the ongoing experiment of the United States. It’s running now until November 3 at the Ensemble Studio Theater in New York City.Ira Flatow is joined by the playwright of “Franklinland,” Lloyd Suh, to learn how he joined all of these elements for the stage.Transcripts for each segment will be available after the show airs on sciencefriday.com.

What exactly is … everything? What is space-time?At one extreme, you’ve got the weird rules of quantum physics that deal with subatomic particles. At the other extreme, you’ve got the vast expanses of space, such as spinning galaxies and black holes.By mapping the cosmic microwave background, surveying the distribution of galaxies around the sky, and listening for gravitational waves, researchers are studying the cosmos for clues to the quantum. They hope that by finding patterns in some of these large-scale structures, tiny irregularities involving quantum effects in the earliest days of the universe might be revealed.Charlie Wood, a staff writer covering physics for Quanta Magazine, has written about some of these space-time mysteries in a special issue. He joins Ira to discuss the nature of space-time and how scientists are trying to decode its physics.Transcript for this segment will be available after the show airs on sciencefriday.com.
