The Inca Empire in South America was one of the most powerful pre-Columbian societies. It was known for the architecture of Machu Picchu, an extensive road network and a system of terraces for agriculture.

Feel like summers are hotter than they used to be? It’s not just your imagination. Climate researchers say that average annual temperatures around the country have been trending upwards for the past 50 years — and are still on the rise.

13:17

Deep sea mining for rare earth elements could start as early as 2026, even as 38 countries have called for a moratorium on it. The metals that companies are targeting are used in many green technologies like electric cars and wind turbines – but mining them is destructive to the environment. Some in the mining industry say the mining is necessary t…

Could labs replace your natural chocolate? 8:50

8:50

Chocolate may fill grocery store shelves around the world, but the raw product that powers chocolate is far more selective. The majority of chocolate farms are found in West Africa and South America – just 20 degrees north or south of the equator. Each farm produces chocolate of a different flavor. Some cocoa tastes fruitier; others, more floral. N…

Thirty years ago, park rangers reintroduced grey wolves into Yellowstone National Park. They wanted to restore the ecosystem and get the elk population, which had decimated the plant community, in check. And it worked – or so the popular narrative suggests. But is it really so simple? Today on the show, we explore how the Yellowstone ecosystem has …

Imagine, you’re a toxic toad hanging around South America. No other animals are gonna mess with you, right? After all, you’re ~toxic~! So if anyone tries to eat you, they’ll be exposed to something called a cardiotonic steroid — and may die of a heart attack. Well, unfortunately, for you, some animals have developed adaptations to these toxic stero…

Sea Camp: Why Scientists Want To Map The Entire Seafloor 14:05

11d ago14:05

14:05

Scientists have mapped less than 30% of the world's seafloor. Experts say that getting that number up to 100% would improve everything from tsunami warnings to the Internet and renewable energy. That's why there's currently a global effort to create a full, detailed map of the seabed by 2030. On today's Sea Camp episode, we talk to Dawn Wright, a m…

In this Back To School episode we consider the "List of Life": the criteria that define what it is to be a living thing. Some are easy calls: A kitten is alive. A grain of salt is not. But what about the tricky cases, like a virus? Or, more importantly, what about futuristic android robots? As part of our Black History Month celebration, developmen…

The Trait That Makes Robots More 'Human' 13:27

13:27

Neurotic, anxious robots like C-3P0 from Star Wars' C-3P0 and Marvin from The Hitchhiker's Guide to the Galaxy are a staple of science fiction — but they're not as common in the real world. Most of the time, the chatbots and artificial intelligence "robots" we encounter are programmed to be extraverted, confident and cheerful. But what if that chan…

14:18

A Chinese scientist, He Jiankui, made a shocking announcement to the world in 2018: He had secretly engineered the birth of the first gene-edited babies. The birth of the twins was seen as reckless and unethical by the scientific community. That’s because, among other things, the CRISPR gene-editing technique Jiankui used was so new. NPR science co…

14:40

How did life start on Earth? The answer is a big scientific mystery scientists are actively investigating. After talking with many scientists, host Regina G. Barber found that an abundance of water on Earth is most likely key, in some way, to the origin of life — specifically, in either deep sea hydrothermal vents or in tide pools. It's for this re…

Why Do Some 80 Year-Olds Have Extraordinary Memories? 8:45

The human brain tends to slow down as we age — even healthy brains shrink. That can make learning and memory harder as people age. But some people’s brains shrink more slowly than their peers. This lucky group is called “SuperAgers.” They’re people aged 80 or older. But they have the memory abilities of someone 50-to-60 years old. This week in the …

Every September, the small town of La Junta, Colorado puts on a whole festival to celebrate a beloved local animal: the tarantula! Around this time of year, thousands of mature male tarantulas start to migrate en masse – but until recently, scientists didn’t know what triggered them to move out of their cozy burrows. On today’s show, biologist Dall…

It’s no secret that stress isn’t good for you. But just how bad is it? Well, in the last few decades, scientists have linked psychological stress to changes in our DNA that look a lot like what happens on the molecular level as we age. Today on the show, host Regina G.

The Giants Lurking In The Deep Sea 13:20

25d ago13:20

13:20

The bathypelagic zone of the ocean is 1,000 to 4,000 meters below the surface. Sometimes it's called the midnight zone because it's too deep for sunlight to reach. Most animals here are much smaller than their shallow-water counterparts. But occasionally, researchers find the rare deep sea giant: giant isopods, giant squids, colossal squids, sea sp…

Much of the country is deep in the middle of a heat wave right now. And every summer, Duane Stilwell's town in Arizona seems to get hotter. It has him worried — and he's not the only one. Since 1980, the average number of heat waves in the U.S has doubled and the average length of a heat wave season has increased from 40 days to 70. Future summers,…

Sea Camp: The Largest Daily Migration On Earth 12:47

1M ago12:47

12:47

The twilight zone of the ocean is a mysterious place. At 200-1000 meters below the surface, it's a tough place to study. That's why, during World War II, people reading sonograms from this zone were perplexed when it looked as if the ocean floor was moving up. Every day. And then back down again before dawn. In this latest installment of Sea Camp, …

Did Spiders' Ancestors Come From The Ocean? 8:51

8:51

Whether you love spiders or can't be within 10 feet of them, you probably think of them crawling around on land. Historically, most researchers would probably say the same thing: Based on the fossil record, they've thought the earliest arachnid ancestors existed around 450 million years ago, living and diversifying exclusively on land. But a new st…

Eating Disorder Recovery In A Diet Culture World 13:45

Eating disorders are complicated illnesses that skyrocketed among teenagers during the COVID-19 pandemic. Pediatrician Eva Trujillo says they "literally rewire the brain," decrease brain size, and make it harder to concentrate and to regulate emotions. Malnutrition can slow the metabolism, impact bone density and even lead to cardiac arrest. But Ev…

Earlier this year, the White House proposed a nearly 24% cut to NASA's 2026 fiscal year budget — the largest in the agency's history. The trims are largely aimed at the NASA's fundamental science research and would halt science that has already been partially paid for, like the Mars sample return and the Nancy Grace Roman Space Telescope.
