Is that spooky old house full of ghosts, or just infrasound?

Old creepy houses are a horror cliche, but why? Why do they freak us out? According to new research, it might have something to do with infrasound: a sound that’s below the range of human hearing, potentially emitted by low-rumbling pipes or old boilers more common in older houses. Psychologist and pseudoscience researcher Rodney Schmaltz explains his new study, and what role infrasound could play in leading people to feel unsettled in “haunted” places. Then, infrasound researcher Milton Garcés breaks down the infrasound that’s produced by volcanoes and asteroid impacts, and how it serves as a “keep away” signal in nature. Guests: Dr. Rodney Schmaltz is a professor of psychology at MacEwan University in Edmonton, Alberta. Dr. Milton Garcés is a research scientist at the Hawai‘i Institute of Geophysics and Planetology and director of the Infrasound Laboratory at the University of Hawai’i in Honolulu.

Use of herbicide linked to Parkinson's is on the rise in the US

The herbicide paraquat is so toxic it’s banned in over 70 countries. But its use in the U.S. is growing, despite known links to Parkinson’s disease. In southeastern Mississippi, an industrial plant is leaking tens of thousands of pounds of the chemical into the air. Environmental reporter Delaney Nolan and epidemiologist Beate Ritz join Host Flora Lichtman to discuss the implications of this leak, and what we know about how paraquat affects the body. Guests: Delaney Nolan is an environmental reporter based in New Orleans. She reported this story for The Lens and the Mississippi River Basin Ag & Water Desk. Dr. Beate Ritz is a professor of epidemiology at UCLA in Los Angeles.

Why does fashion repeat in 20-year cycles? Math has the answer

Bucket hats. Low-rise jeans. Track suits. As you might’ve noticed, Y2K fashion is in right now. People say that fashion moves in 20-year cycles, and it turns out…it does! At least according to math. Host Flora Lichtman sits down with mathematician Emma Zajdela to figure out how she analyzed over 35,000 images of women's clothing dating all the way back to the 1860s to confirm this theory. Guest: Dr. Emma Zajdela is a Franco-American mathematician and science diplomacy activist.

How yawning might help clear dirty fluid from the brain

Just about every animal with a backbone yawns (maybe even dinosaurs), but why we do it is still something of a mystery. A SciFri listener from Texas recently spotted some research that suggests yawning could play a role in clearing waste products from the brain, and asked us to get to the bottom of it. Biomechanical engineer Lynne Bilston, an author on that study, joins Flora to discuss the findings and what they could mean for neurodegenerative diseases like Alzheimer's. Plus, about a third of Americans aren’t getting the recommended seven hours of sleep per night, according to a new CDC report. We check in with sleep researcher Stuti Jaiswal to break down the report and find out how to get a better night's sleep. Check out an MRI video of what yawning looks like inside the body. Guests: Dr. Lynne Bilston is a biomechanical engineer at UNSW Sydney in Australia. Dr. Stuti Jaiswal is a physician scientist and co-director, education at Scripps Research Translational Institute in San Diego, California.

Earth's ancient hydrogen, and fossilized vomit

A recent study simulated the extreme temperatures and pressure of the Earth’s interior by squeezing a sample between diamonds and heating it with a laser. In those simulations, researchers found that the Earth’s core may contain vast amounts of hydrogen, locked away in alloys with iron and silicon. Planetary scientist Anat Shahar joins Host Ira Flatow to discuss what this tells us about how the planet formed, and where water on Earth may have come from. Then, another kind of deep history: Paleontologist Arnaud Rebillard introduces Host Flora Lichtman to “regurgitalite”—fossilized vomit. Rebillard studied a sample of regurgitalite some 50 million years older than the dinosaurs. Guests: Dr. Anat Shahar is a planetary scientist, and vice president for research at the Carnegie Institution for Science in Washington, D.C. Arnaud Rebillard is a PhD candidate in paleontology at the Natural History Museum of Berlin. Other episodes you may enjoy: Could Underground Hydrogen Reserves Put Clean Energy Within Reach?

How El Niño shapes the world’s weather trends

Scientists studying climate models say there’s a high chance this will be an El Niño year—and that we could be in for a “super” El Niño. The difference is indicated by sea surface temperatures in part of the Pacific Ocean rising a little—or a lot—above their long-term average. El Niño is one half of what climatologists call the ENSO, the El Niño-Southern Oscillation. The oscillation operates on a roughly 3-7 year cycle, changing the path of the jet stream and shifting weather conditions around the world. An El Niño year, for instance, typically brings wetter weather in the western U.S. but dryer conditions in the Pacific Northwest, and can be a drought buster for regions such as southern California. But shifting ocean currents also have the potential to affect marine ecosystems, leading to algal booms, coral bleaching, and more. Climate scientist Dillon Amaya joins Host Ira Flatow to describe the role of the El Niño in shaping world weather, and what effects a particularly strong El Niño year might have on global ecosystems. Guest: Dr. Dillon Amaya is a research scientist at the NOAA Physical Sciences Laboratory in Boulder, Colorado.

Understanding the gynecological health crisis facing Black women

When Kemi Doll was in medical school, she learned that Black women are twice as likely to die from uterine cancer as white women, and also suffer disproportionately from other uterine-related conditions. What wasn’t explained was why. Now a gynecologic oncologist, Doll has made it her mission to change these trends and improve care for Black women. She joins Flora to discuss her new book, “A Terrible Strength: The Hidden Crisis of the Black Womb and Your Survival Guide to Healing.” They explore the way systemic racism and the normalization of Black women’s pain lead to later diagnoses of uterine cancer and poorer health outcomes for a range of gynecologic conditions including fibroids, endometriosis, and heavy periods. And Doll explains the problem with using reproductive health as a synonym for uterine health. Guest: Dr. Kemi Doll is a gynecologic oncologist and professor at the University of Washington Schools of Medicine and Public Health. Other episodes you may enjoy: Endometriosis Is Common.

Why so many studies can’t be replicated

How do we know what we know? That's where science comes in—it gives us a method for testing our ideas and getting trustworthy results. But some researchers have warned that many scientific studies can't be replicated. To find out how deep the problem goes, the US Defense Advanced Research Projects Agency funded one of the largest analyses of social science, called the SCORE project. They checked the results of thousands of papers across economics, education, and psychology—and found that only half of them could be replicated. Joining Host Ira Flatow to discuss the findings are Tim Errington, one of the leads on this project, and economist Abel Brodeur, who recently released the results of a separate replication study that found more encouraging results than SCORE did. Guest: Dr. Tim Errington is senior director of research at the Center For Open Science in Washington, D.C. Dr. Abel Brodeur is a professor of economics at the University of Ottawa and founder of the Institute for Replication. Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Can GLP-1 drugs treat addiction?

GLP-1 drugs like Ozempic, Wegovy, and Zepbound are prescribed for weight loss, diabetes, and blood-sugar management. But as more people use them, patients are reporting a decrease in cravings for drugs and alcohol. Researchers are now investigating whether GLP-1s might be effective for treating alcohol and drug addiction. How much do we know? What are the risks? And do these drugs tell us anything new about the biology of addiction? Host Flora Lichtman talks with neuroscientist Joseph Schacht, who is conducting a clinical trial on GLP-1s and alcohol use; and Sarah Carstens, addictions clinical director of Outpatient Services at Penn Medicine’s Princeton House Behavioral Health. Guests: Dr. Joseph Schacht is the co-director of the Division of Addiction Science, Prevention, and Treatment at the University of Colorado Anschutz School of Medicine. Sarah Carstens is the addictions clinical director of Outpatient Services at Penn Medicine’s Princeton House Behavioral Health.
