Accurate weather forecasting can be a matter of life or death. So countries with less money like Mozambique face a big challenge. They can't build and maintain their own weather radar or satellites. Instead, they rely on weather maps created by wealthier countries, like the U.S. NPR climate reporter Becky Hersher tells us what that means for Mozambique, a country where the weather's gotten worse a...

Storytelling can be a powerful tool to convey information, even in the world of science. It can also shift stereotypes about who scientists are. We talked to someone who knows all about this - Liz Neeley, the Executive Director of Story Collider, a nonprofit focused on telling "true, personal stories about science." You can tell us your personal science stories by emailing, shortwave@npr.org . Plu...

Since the dawn of Sputnik in 1957, space-faring nations have been filling Earth's orbit with satellites. Think GPS, weather forecasting, telecommunications satellites. But as those have increased, so, too, has space junk. On today's show, we talk about the first mission to clean up space junk and the problem debris poses to sustainability in space. See pcm.adswizz.com for information about our col...

Host Maddie Sofia and reporter Emily Kwong evaluate what truth there is to the popular phrases "blind as a bat" and "memory of a goldfish."

Some dairy farmers in Massachusetts are using food waste and manure to create renewable energy. Each farm produces enough to power about 1,500 homes. Not only does this process create electricity, NPR Science Correspondent Allison Aubrey tells us it also prevents the release of methane, a greenhouse gas.

There aren't that many options for putting your loved ones to rest. There's burial. There's cremation. Now, later this year in Washington state, it'll be legal to compost a human body. Soil scientist Lynne Carpenter-Boggs tells us how the process works and why she describes it as "beautiful." Carpenter-Boggs is also a research advisor at Recompose, a human composting company in Washington. Follow...

Astrophysicist Adam Frank is a big fan of science and movies. He's even been a science adviser to Marvel's "Doctor Strange." So we asked Adam to give us his sci-fi films of the decade - movies that tell us about striking the right balance between science and storytelling. Here are the movies we couldn't get to in the episode: 'Annihilation' (2018), 'Coherence' (2013), 'Gravity' (2013) and 'Looper'...
