2024/10/28

What's your favorite apple? Maybe it's the crowd-pleasing Honeycrisp, the tart Granny Smith or the infamous Red Delicious. Either way, before that apple made it to your local grocery store or orchard it had to be invented — by a scientist. So today, we're going straight to the source: Talking to an apple breeder. Producer Hannah Chinn reports how apples are selected, bred, grown ... and the discoveries that could change that process. Plus, what's a "spitter"?Want to know how science impacts other

2024/10/25

More than a million species are at risk of extinction, many within decades, because of human actions. Among them? The kāhuli, Hawaii's native tree snails that are some of the most endangered animals on the planet. At one point, there used to be about 750 species of snails in Hawaii — almost all of them found nowhere else. Now, they are rapidly disappearing.

A Brand New Kind of Schizophrenia Treatment

Short Wave ·

2024/10/23

For the past 70 years, schizophrenia treatments all targeted the same chemical: dopamine. While that works for some, it causes brutal side effects for others. An antipsychotic drug approved last month by the FDA changes that. It triggers muscarinic receptors instead of dopamine receptors. The drug is the result of a chance scientific finding ... from a study that wasn't even focused on schizophrenia. Host Emily Kwong and NPR pharmaceutical correspondent Sydney Lupkin dive into where the drug

'Ghost Genes' Could Help Save The American Red Wolf

Short Wave ·

2024/10/22

Every American red wolf alive right now is descended from only 14 canids. In the 1970s, humans drove the red wolf to the brink of extinction. Because of that, red wolves today have low genetic diversity. But what if we could recover that diversity ... using "ghost genes"? That's right, today's episode is a ghost story. Along the way, we get into gene dictionaries, the possibilities of poo and how a photo of a common Texas coyote started it all.Have another animal you want us to dig into for a future

New Frogs Just Dropped

Short Wave ·

2024/10/18

In the humid rainforests of northern and eastern Madagascar reside seven newly described frog species. They often hang out near fast, flowing rivers. These treefrogs' high-pitched, "futuristic" sounds may help male frogs attract females over the sound of nearby rushing water. They also are what inspired their Star Trek-themed names.

What The Heck Is A Rock Glacier?

Even though there are more than 10,000 rock glaciers in the western United States, most people would look at one without knowing it. Unlike the snowy glaciers we're more familiar with, rock glaciers are under-researched and hiding in plain sight. But inside these glaciers covered with rocks is a little bit of climate hope.Read more of science correspondent Nell Greenfieldboyce's reporting here.

Anxious? Try Watching A Scary Movie

2024/10/09

In human history, fear kept us safe when running from predators and anxiety kept us from going back to that lion-infested area. But what happens when these feelings get out of hand in humans today? And why do some of us crave that feeling from scary movies or haunted houses? For answers, we turn to Arash Javanbakht, a psychiatrist from Wayne State University.

How Do You Spot A Liar?

Short Wave ·

2024/10/08

For over a century, we've been inventing technology to catch liars in the act. To this end, the polygraph was invented and became wildly popular in the mid-20th century. Then, there was an era of "micro-expression training," which claimed person could be caught lying through a skilled analysis of their face. Now, there's talk of using artificial intelligence to analyze the human voice. But do any of these methods even work? And if not ... what are the risks? Emily and Gina investigates how deception

Fruit fly brains are smaller than a poppy seed, but that doesn't mean they aren't complex. For the first time, researchers have published a complete diagram of 50 million connections in an adult fruit flies brain. The journal Nature simultaneously published nine papers related to this new brain map. Until now, only a roundworm and a fruit fly larva had been mapped in this way.Read more of science correspondent Jon Hamilton's reporting here. Want to know more about the future of brain science?

2024/10/04

Lightning: It happens all the time, and yet the exact details of how it's made has long eluded scientists. That is, until now. New research out this week in the journal Nature holds new insights into the precursor to lightning. To figure it out, researchers flew a NASA ER-2 – essentially the research version of a spy plane – over several tropical thunderstorms. What they found: The same high energy radiation is found in places like neutron stars and around black holes. Want to hear more stories

Years ago, astronomy professors started noticing something that troubled them: Many of their students didn't understand climate change and the science supporting it. So a small group of professors decided to do something about it — teach climate change in their introductory astronomy courses. Want to hear more stories about climate change?

Do NYC Birds Hold The Clues To The Next Pandemic?

Most viruses that become epidemics in humans begin in other animals. It's how scientists suspect COVID-19 emerged. And now, less than five years after the start of the pandemic, some scientists are concerned about another disease that could do something similar: bird flu, or H5N1. Over the past year, the virus has spilled into cows and other animals — even infecting some people working closely with the animals.

The Reality Of OCD

Around 2% of the global population struggles with obsessive compulsive disorder, or OCD. That's roughly 163 million people who go through cycles of obsessions – unwanted intrusive thoughts, images or urges – and compulsions, or behaviors to decrease the distress caused by these thoughts. In movies and TV, characters with OCD are often depicted washing their hands or obsessing about symmetry. Dr. Carolyn Rodriguez says these are often symptoms of OCD, but they're not the only ways it manifests – and

At the beginning of the universe, annihilation reigned supreme. Equal amounts of matter and antimatter collided. There should have been nothing left. And, yet, here we all are. Matter won out. The question is: why? Scientists are probing the mysteries of a ghostly subatomic particle for answers. To do it, they'll need to shoot a beam of them 800 miles underground.
