Towana Looney became the first living person in the world to get a kidney from a new kind of genetically modified pig last month. Health correspondent Rob Stein got exclusive access to be in the operating room.

Towana is a 53-year-old grandmother from Gadsden, Ala. She's been on dialysis for four hours a day, three days a week since 2016. Her immune system would reject a human kidney. So the Food and Drug Administration made an exception to its usual clinical study requirements to allow Looney this new kind of pig kidney. But the procedure is controversial.

Old mines leave behind a a pressing problem: Huge holes that make the landscape look like a chunk of swiss cheese. But in Germany, some scientists and city planners are turning these into lakes.

The largest one will be the biggest artificial lake in Germany when it's done, with a shoreline of 26 kilometers or about 16 miles all around.

But it's not as easy as simply filling the holes with water. It takes a LOT of research to get this science right.

AI uses a lot of power. Some of the next generation data centers may use as much power as one million U.S. households. Technology companies like Microsoft, Google, Amazon and Meta hope nuclear power will offer a climate solution for this energy use. Nuclear power plants can deliver hundreds of megawatts of power without producing greenhouse gas emissions. But some long-time watchers of the nuclear industry are skeptical that it's the right investment for big tech companies to make.

Racism is often covered as a political, cultural, or news story. But how is it affecting people's health? That's the question Cara Anthony, a KFF News reporter, wanted to answer: not just on an individual scale, but on a community-wide one. So for the past few years, she's been reporting on a small town in the Midwest that illustrates that health issue: Sikeston, Missouri. Today on the show, Cara walks host Emily Kwong through Sikeston's history — and what locals and medical experts have to say about how that history continues to shape the present.

For more of Cara's reporting, you can check out KFF Health News' documentary and four-part podcast series, Silence in Sikeston.

The federal government has been tracking the weather for more than 150 years. Yet over the last few decades, the rise of the Internet and big tech have made weather forecasting a more crowded space. Today, our colleagues at NPR's daily economics podcast The Indicator report on the value of an accurate forecast and the debate over who should control weather data.

In the 1950s, scientists exposed a tin of meat to a dose of radiation that they expected would kill all forms of life. But one organism defied the odds and lived: Conan The Bacterium. Turns out this microorganism, known to science as Deinococcus radiodurans, is capable of surviving extreme levels of radiation — thousands of times the amount that would kill a human. So what's Conan's secret?

Thor. Loki. Heimdall. They're not just Norse gods or Marvel characters. They're also the names of various Asgard archaea. These microscopic organisms are found all over the world, from marine sediment to mud volcanoes to hydrothermal vents. A growing body of research suggests we owe them an evolutionary debt. This episode, Emily and guest host Jon Hamilton explore the wild world of archaea: Where are they from? What do they do? And what can they tell us about the origins of life on earth?

If you crossed WALL-E with a floor lamp, it might look a little like the PhytoPatholoBot. These robots aren't roving through space or decorating a living room — they're monitoring the stems, leaves and fruit of Cornell AgriTech's vineyards, rolling down each row and scanning for mildew.

In this episode, host Emily Kwong and producer Hannah Chinn take a trip to Cornell to check out these new robots. How do they work? How effective are they? And what do local grape farmers – and neighbors – think about them?

The next four years may be challenging for foreign-born scientists who want to work in the United States. Foreign-born workers account for about half of the doctoral-level scientists and engineers working in the U.S., but the incoming Trump administration wants to make it harder for them to get H-1B visas. Some scientists worry a scarcity of H-1B visas may prompt top foreign researchers to work in other countries.

Centuries ago, Southwest tribal nations tended vast orchards of peach trees. But in 1863, thousands of those trees were cut down by the United States government when it ordered the Diné to leave their land as part of the Long Walk. Horticulturalist Reagan Wtysalucy wants to bring that those Southwest peaches back.

The Vertebrate Genomes Project: It's an ambitious effort by an international group of scientists to create a "Genome Ark" by sequencing the genomes of about 70,000 animal species. The hope is that through all of this gene sequencing, scientists will be able to answer some basic but important questions like: What makes a bird, well, a bird? What makes a mammal a mammal? Plus, with so many species on the verge of extinction, can scientists record their genetic information before they go extinct – or better yet, maybe help save the population from going extinct? Guest host Jon Hamilton, one of our favorite science correspondents, talks to Erich Jarvis, the chair of this project, to learn what this ark of animal genomes could mean for our future – and why a platypus qualified for early boarding.
