- Like Being Scared? Here’s WhyLike haunted houses? Scientists do! That’s because they’re an excellent place to study how humans respond to – and even actively seek out – fear. In an immersive threat setting, as opposed to a carefully controlled lab, researchers can learn a lot about what scares people, why and how additional factors (like the presence of friends) might affect our experiences.
So what have they learned? What determines a good scare versus a bad one? And what’s the evolutionary reason for all of this, anyway? In today’s episode, producer Hannah Chinn heads to the haunted house in search of answers.

NPR Privacy Policy15 min - Nature Quest: Rebuild Or Relocate Post-Disaster?In the face of floods, wildfires and other natural disasters, when should a community relocate to avoid potential harm? Listener Molly Magid asks that very question. Molly wanted to know how other communities have chosen the path of “managed retreat.” That’s the purposeful and coordinated movement of people and assets out of harm’s way. In today’s episode, Short Wave's Emily Kwong and Hannah Chinn explore cases from New York to Illinois and Alaska to see how successful relocation happens — and what stops it.

NPR Privacy Policy15 min - What Works – And Doesn’t – For Hair Loss?People may think of hair loss as a guy thing. But by some estimates, half of all women experience hair loss in their lifetime. And when your social media algorithm gets a whiff? Good. Luck. There are some solutions out there based in science, but not every remedy works for every person — or every type of hair loss. (Yes, there are different types. And the type you have matters!) So today, pharmaceuticals correspondent Sydney Lupkin guest hosts the show to talk about causes of hair loss and how to figure out which treatments may be best for you.

NPR Privacy Policy12 min - Parasites Have Haunted Us For Millions Of YearsParasites have roamed the Earth for a long time. They were here before the dinosaurs: The oldest fossils are more than 500 million years old. Today on the show, Regina G. Barber speaks with paleontologists Karma Nanglu and Danielle de Carle about a mysterious fossil called the “Riddler,” and the oldest-ever leech fossil. They share stories of the enduring power of parasitism through the ages and why the clues to prehistoric mysteries may be tucked in a basement.

NPR Privacy Policy15 min - Migrating Birds Have a Big, Clear ProblemAround this time of year, every night, a quiet exodus is occurring. Hundreds of millions of birds are migrating thousands of miles south for the winter. One of the biggest dangers for these tiny travelers? Glass.
Researchers estimate that every year in the U. S., collisions with glass windows take out at least a billion birds. Even if the birds initially fly away, these collisions can cause concussions, broken bones, and other injuries; most victims don’t survive.
After much reporting, NPR science correspondent Nell Greenfieldboyce has found … it doesn’t have to be this way. Scientists and researchers have studied how to stop collisions from happening, and examples around the country indicate that even little solutions can make a big difference.

NPR Privacy Policy16 min - We Have the Cure. Why is Tuberculosis Still Around?Tuberculosis – the world’s deadliest infectious disease – could be dormant in your system for years before you realize you have it. In the U.S., it’s relatively rare; provisional data shows that there were just over 10,000 cases in 2024. But in other parts of the world, especially lower-income countries, the disease is spreading much more actively. Worldwide, more than 10 million people are diagnosed with an active tuberculosis infection every year. And even though modern medicine has all the tools to cure it, over a million people around the world still die from the sickness annually.
Author John Green thinks that’s a problem. In his book Everything is Tuberculosis, he charts the spread of tuberculosis in the past to the lessons it has to teach us in the present.

NPR Privacy Policy16 min - Should Scientists Genetically Engineer Wild Species?Some scientists looking to preserve vulnerable species have turned to a controversial technique: synthetic biology. This catchall term often means genetic engineering – introducing new genes to an organism. And a recent narrow vote by the International Union for Conservation of Nature on using the technology shows how divided scientists are on the issue of releasing genetically altered species. Science correspondent Nate Rott wades into the debate with us and reveals whether or not the Union voted to place a moratorium on releasing gene-edited species.

NPR Privacy Policy14 min - Science Says Quitting Smoking At Any Age Is Good For The BrainThe rate of smoking cigarettes has steadily declined since the 1960s – when Congress required warnings on cigarette boxes. Research shows that people are more likely to try to quit smoking when they’re under 40. But a new study in the journal The Lancet Healthy Longevity shows that quitting later in life can still be beneficial – and could possibly lower your risk for dementia. For this and more news from the science journals, Short Wave hosts Regina G. Barber and Emily Kwong talk with All Things Considered host Mary Louise Kelly.

NPR Privacy Policy9 min - What Happens When You're Under Anesthesia?
It's World Anesthesia Day tomorrow! So, we invite you to take a deep breathe. Picture a relaxing scene. Maybe a beach in Tahiti, your toes in the sand, a cold drink in hand. Now imagine your favorite music playing in the background. If Dr. Alopi Patel were your anesthesiologist, that's exactly what she'd have you do while you waited for surgery. Before she puts patients under the sway of anesthesia, she likes to explain everything that will happen after they lose consciousness and lead them in guided imagery to help them relax before their procedure. She calls this "verbal anesthesia," and says "it's a type of anesthesia you can't really put in an I.V." Anesthesia is a cornerstone of modern medicine makes tons of surgeries possible today. But Dr. Patel says it wasn't always this way — and shares the history and mechanisms behind this once-controversial procedure. (encore)

NPR Privacy Policy15 min - Why Legal Weed Isn’t Always SafeMarijuana is decriminalized or legal in some form in multiple states. But, because it’s illegal on the federal level, states have had to build their own regulatory infrastructure. Without a centralized body to guide them, regulations in one state can look vastly different from those in another. For more on the scope of the issue, Short Wave host Regina G. Barber talks to independent science journalist Teresa Carr and NPR pharmaceuticals correspondent Sydney Lupkin.
Read more of Teresa’s reporting on state marijuana testing, and more of Sydney’s reporting on the ways California is trying to make weed safer.
