Short Wave Folgen

Reading the science headlines this week, we have A LOT of questions. Why are more animals than just humans saddled — er, blessed — with vocal fry? Why should we care if 8 million year old plankton fossils are in different locations than plankton living today? And is humanity finally united on protecting the Earth's seas with the creation of the Biodiversity Beyond National Jurisdiction treaty? Luckily, it's the job of the Short Wave team to decipher the science behind the headlines. This week, that deciphering comes from co-hosts Emily Kwong and Aaron Scott, with the help of NPR climate correspondent Lauren Sommer. Hang out with us as we dish on some of the coolest science stories in this ocean-themed installment of our regular newsy get-togethers!

Have you ever wondered how biologists choose what animal to use in their research? Since scientists can't do a lot of basic research on people, they study animals to shed light on everything from human health to ecosystems to genetics. And yet, just a handful of critters appear over and over again. Why the mouse? Or the fruit fly? Or the zebrafish? Cassandra Extavour, an evolutionary biologist at Harvard, talked with Short Wave co-host Aaron Scott about her favorite new model critter on the block: crickets. (Well, "favorite" might be a strong word. As Cassandra concedes, "to be honest, my opinion about crickets is sort of neutral to slightly grossed out.") On today's episode we leave the mouse to its maze, and instead consider the cricket and all the amazing things it can teach us.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

The whitebark pine is a hardy tree that grows in an area stretching from British Columbia, Canada south to parts of California and east to Montana. It's a keystone species in its subalpine and timberline ecosystems and plays an outsized role in its interactions with other species and the land — feeding and providing habitat for other animals, and providing shade to slow glacial melt to the valleys below. But it's increasingly threatened — by more intense fires, by mountain pine beetle infestations and by a deadly fungus called blister rust. Today, producer Berly McCoy takes the microphone to share the ongoing efforts by reforestation forester ShiNaasha Pete and others to save this important species.Check out the Headwaters Podcast: https://glacier.org/headwaters/ Reach the show by emailing shortwave@npr.org.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy
