Harnessing The Ghost Particles Blasting Through You

Short Wave ·

2024/09/24

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.

Solving The EV Battery Recycling Puzzle

Short Wave ·

2024/09/23

Electric vehicle batteries will all, eventually, reach the end of their lives. When that happens, they should be recycled. But what breakthroughs could make that happen cleanly, efficiently — and close to home? Today, business correspondent Camila Domonoske takes us on a tour of one company trying to crack the EV battery recycling puzzle — to learn what this case study can tell us about the larger battery picture. Plus, why recycling is kind of like wresting with Lego bricks.Read more of Camila's

Hey, Short Wavers! Today we're sharing an excerpt of the new NPR podcast How To Do Everything.

Are Crabs The Final Form?

Short Wave ·

2024/09/18

Evolution keeps making crabs. In fact, it's happened so often that there's a special scientific term for an organism turning crab-like: carcinization. But how many times has it happened, and why? When did the very first crab originate? What about all the times crabs have been unmade? And does all this mean that we, too, will eventually become crabs? In this episode, host Emily Kwong chats with Javier Luque about crabs, carcinization and change.Want more paleontological science stories? Email us at

2024/09/17

Patrick Anderson is widely recognized as the greatest wheelchair basketball player of all time. He's represented Canada at the Paralympics six times and led his team to win three gold — and one silver — medals. But since he first started playing in the 1990s, the sport has changed dramatically. He says that's due in part to the technological innovations in wheelchair athletics. In this episode, guest host Andrew Mambo chats with Patrick about the reasons for these changes.

What's Up With The Hot Ocean Temperatures?

2024/09/16

Hurricane season is heating up: Hurricane Francine hit Louisiana last week and dumped rain across the South, and forecasters expect more stormy activity in the Atlantic in the next few weeks. A big factor in this stormy weather is our extremely warm oceans. Scientists know climate change is the main culprit, but NPR climate correspondent Rebecca Hersher has been following the quest to figure out the other reasons.

Solutions Week: Reducing The Food Waste Problem

Short Wave ·

2024/09/13

We close out Climate Solutions Week with a look at the final step in the food system: waste. Roughly 30-40% of all food produced globally gets thrown out — a huge problem when it comes to climate change. Shuggie's Trash Pie and Natural Wine has answers for what to do with all that waste – be it bruised fruit and wilted greens salad or meatballs made out of beef hearts. The San Francisco restaurant describes itself as a "climate-solutions restaurant" — and they're hoping you find these dishes

Solutions Week: Reinventing Chocolate

Short Wave ·

2024/09/11

Climate change is contributing to erratic weather where cocoa beans are grown and threatening the global chocolate supply. Record rainfall last year led to fungal infections among cacao trees and dwindled supply of cocoa beans. Heat is also making it more difficult for cocoa beans to thrive. So, for day three of Climate Solutions Week, we look at one innovation in the food industry: chocolate substitutes. As big chocolate manufacturers rush to stockpile cocoa beans, some companies like Planet A

Short Wave producer Hannah Chinn has adult-onset eczema. They're not the only one. Up to ten percent of people in the United States have it, according to the National Eczema Association — and its prevalence is increasing. Despite its ubiquity, a lot about this skin condition remains a mystery. So today, Hannah's getting answers. They sat down with Raj Fadadu, a dermatologist at UC San Diego, to ask: What is eczema?

Are You Overestimating The Algorithm?

2024/09/03

Humans hallucinate. Algorithms lie. At least, that's one difference that Joy Buolamwini and Kyle Chayka want to make clear. When ChatGPT tells you that a book exists when it doesn't – or professes its undying love – that's often called a "hallucination." Buolamwini, a computer scientist, prefers to call it "spicy autocomplete." But not all algorithmic errors are as innocuous. So today's show, we get into: How do algorithms work? What are their impacts? And how can we speak up about changing them

What's Missing From The Invasive Species Narrative?

2024/08/28

At first glance, the whole narrative of aquatic invasive species may seem straightforward: A bad non-native species comes into a new ecosystem and overruns good native species. But the truth? It's a little more complicated. To tear down everything we thought we knew about invasive species and construct a more nuanced picture, host Emily Kwong talks to experts Ian Pfingsten, who works on the United States Geological Survey's Nonindigenous Aquatic Species Database, and Nicholas Reo, a Canada

Preserving Your Humanity In The Age Of Robots

2024/08/27

Human beings are hardwired for social connection – so much so that we think of even the most basic objects as having feelings or experiences. (Yup, we're talking to you, Roomba owners!) Social robots add a layer to this. They're designed to make us feel like they're our friends. They can do things like care for children, the elderly or act as partners. But there's a darker side to them, too. They may encourage us to opt out of authentic, real-life connections, making us feel more isolated. Today on
