Under a 1971 Congressional Act, the Bureau of Land Management has the right to round up wild horses on public lands. Oftentimes, those horses are shipped to holding facilities, where they are kept in captivity and separated from their families. William Simpson wants to change that. He wants to deploy the wild horses across public lands, to live and graze — and ultimately, prevent the worst wildfires.

Jul 29, 2022•14 min•Ep 707•Transcript available on Metacast Our ancestors evolved the ability to taste the sweet goodness of foods like pastries and creamy chocolates.

Jul 25, 2022•16 min•Ep 703•Transcript available on Metacast The Food and Drug Administration allows faster drug approvals based on preliminary study data if the drug fulfills an unmet medical need. But the speedy approval comes with a promise that the drugmaker does another clinical trial once the drug is on the market to prove it really works. If not, the FDA can rescind the approval. How are the companies doing and how well does the agency enforce that system? Pharmaceuticals correspondent Sydney Lupkin investigated the 30-year track record for acceler...

Jul 21, 2022•12 min•Ep 701•Transcript available on Metacast Host Emily Kwong wants to keep an eye on her carbon footprint. Most of it consists of greenhouse gas emissions from driving her car or buying meat at the grocery store. But it's not so obvious how to measure those emissions, or how factories, cargo ships, or even whole countries measure theirs. Enter: NPR science reporter Rebecca Hersher. Together, Rebecca and Emily break down how greenhouse gas emissions are tallied ... and why those measurements are so important in figuring out who's responsib...
Jul 20, 2022•15 min•Ep 700•Transcript available on Metacast In the 18th century the world was focused on Venus. Expeditions were launched in pursuit of exact measurements of Venus as it passed between Earth and the Sun. By viewing its journey and location on the Sun's surface, scientists hoped to make a massive leap in scientific knowledge. With a little help from math, Scientist in Residence Regina G. Barber recounts how humanity came closer to understanding our cosmic address — and relative distances to other planets — in the solar system. You can foll...

Jul 14, 2022•14 min•Ep 696•Transcript available on Metacast For centuries, mysterious blocks of beeswax and Chinese porcelain have washed up on the Oregon coast, leading to legends of pirates, treasure, and a sunken Spanish galleon. It became known as the Beeswax Wreck, and it inspired centuries of treasure hunters—and maybe even Steven Spielberg, as he created The Goonies . Now, researchers have found nearly 330-year-old timbers from the ship in a hard-to-access cave. This is the story of how a team of volunteer archeologists are working to solve one of...

Jul 06, 2022•13 min•Ep 690•Transcript available on Metacast Being small has its advantages ... and some limitations. One organism that intimately knows the pros and cons of being mini is the pumpkin toadlet. As an adult, the animal reaches merely the size of the skittle. At that scale, the frog's inner ear is so small, it's not fully functional. That means when the frog moves, it's haphazard and seems kind of drunk. And so today, with the help of Atlantic science writer Katie Wu , we investigate: If a frog can't jump well, is it still a frog? Read Katie'...

Jun 29, 2022•12 min•Ep 685•Transcript available on Metacast Historically, the California condor soared across the western skies of North America. But by the 1980s, the bird was on the edge of extinction — just 22 remained.
