  • Nature Quest: Are Summers Getting Hotter?
    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, experts say, will be even hotter. But why exactly is that happening, and what can people do to protect themselves from the heat?This episode is part of Nature Quest, a monthly segment that answers listeners' questions about their local environment.

  • Sea Camp: The Largest Daily Migration On Earth
    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, we explore what this historical mystery has to do with the Earth's ability to cycle and store carbon in the ocean's watery depths.SIGN UP FOR OUR SEA CAMP NEWSLETTER!

  • Did Spiders' Ancestors Come From The Ocean?
    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 study out this week in the journal Current Biology suggests arachnid brains may have originated much earlier in the ocean. Want to hear more stories about the history of animals on Earth?

  • Eating Disorder Recovery In A Diet Culture World
    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 Eva says, with the right treatment, people can also recover fully. She's the president of the International Association of Eating Disorder Professionals and co-founder of Comenzar de Nuevo, a leading treatment facility in Latin America. Today on the show, host Emily Kwong talks about the physical and mental impacts of eating disorders with Dr. Trujillo and Moorea Friedmann, a teen mental health advocate and host of the podcast Balancing Act. Plus, how to recover in a world steeped in diet culture. Want us to cover more mental health topics? Tell us by emailing [email protected]! We'd love to know what you want to hear from us!

  • Will Federal Budget Cuts Affect Space Science?
    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. Many scientists and policy experts are also worried that the reduced funding would cause a scientific brain drain. But within the last month, Congress has started to discuss appropriations packages that may not severely contract the budget after all. So, in this episode, Regina reports on the important hypotheticals: What programs might be affected? Are these cuts likely to happen? If so, when? Want to hear more stories about space and policy?
