The California condor used to soar across the western skies of North America, but by the 1980s, the bird was on the edge of extinction — just 22 remained. Thanks to decades of conservation work, the California condor population has rebounded to a couple hundred birds in Central California and Arizona.
This past May, a large partnership led by the Yurok Tribe re-introduced the birds to Northern California. Today, host Aaron Scott talks to Yurok biologist Tiana Williams-Claussen about the years-long quest to return the birds to their ancestral skies, and the importance of condor — who the Yurok call Prey-go-neesh — to the Yurok people and the natural world.

Since the first successful in vitro fertilization pregnancy and live birth in 1978, nearly half a million babies have been born using IVF in the United States. Assisted reproductive technology has made it possible for more people to become parents, but it's not accessible to everyone. Reproductive endocrinologist Amanda Adeleye explains the science behind IVF, the barriers to accessing it and her concerns about fertility treatment in a world without the legal protections of Roe v. Wade.

Scorpions: They're found pretty much everywhere, and new species are being identified all the time. Arachnologist Lauren Esposito says there's a lot to love about this oft-misunderstood creature. Most are harmless — they can't even jump — and they play a critical role in their diverse ecosystems as a top invertebrate predator.
Want to hear us talk about other newly identified animal species? We'd love to know! We're at @NPRShortWave on Twitter, and our email is shortwave@npr.org.

ALS is a disease that destroys the nerve cells in the brain and spinal cord we need for voluntary movement. There is no cure, but now there is a newly approved medication that may slow down the disease and extend patients' lives. The drug, called Relyvrio, got its start with a couple of college students, some "ice bucket challenge" money, and a new approach to targeting this disease. Neuroscience correspondent Jon Hamilton checks in with host Emily Kwong about why some advisors aren't persuaded the drug works and how you weigh promising but limited evidence against the backdrop of a 100% fatal disease with hardly any other treatment options?

When a disaster like Hurricane Ian destroys a house, the clock starts ticking. It gets harder for sick people to take their medications, medical devices may stop working without electricity, excessive temperatures, mold, or other factors may threaten someone's health. Every day without stable shelter puts people in danger.
The federal government is supposed to help prevent that cascade of problems, but an NPR investigation finds that the people who need help the most are often less likely to get it. Today we encore a conversation between NPR climate reporter Rebecca Hersher and Short Wave guest host Rhitu Chatterjee.

On August 18, 2015, in Sitka, Alaska, a slope above a subdivision of homes under construction gave way. This landslide demolished a building and killed three people. Today on the show, host Emily Kwong recounts the story of the Kramer Avenue landslide and talks about how scientists and residents implemented an early warning system for landslides to prevent a future disaster.

The last several decades have taken a toll on the oceans: Some fish populations are collapsing, plastic is an increasing problem and climate change is leading to coral bleaching — as well as a host of other problems. But marine biologist and World Economic Forum programme lead Alfredo Giron says there's room to hope for the seas. He works to create systems that governments and the fishing industry can use to make sure fishing is legal and sustainable so oceans thrive for years to come. He talks to host Aaron Scott about his work and how managing the ocean is a lot about managing people.

What's in a grassland? There are all sorts of wildflowers, many insects, animals like prairie dogs, bison and antelope — and beneath the surface, there's a lot of carbon. According to some estimates, up to a third of the carbon stored on land is found in grasslands. But grasslands are disappearing — just like forests. Today, journalist Julia Rosen shares her reporting on the hidden majesty and importance of the grasslands.
To learn more, including what colonialism has to do with disappearing grasslands, check out Julia's article in The Atlantic, "Trees Are Overrated".
