Pluto was unseated as our solar system’s ninth planet in 2006. Since then astronomers have found signs that a real ninth planet could be hiding at the edges of our solar system. Clara Moskowitz, senior editor for space and physics, explains how the forthcoming Vera Rubin Observatory could give researchers a way to find the real Planet Nine—if it’s out there.

Going outside has many benefits, from positively affecting our nervous system to diversifying our microbiome. But you don’t need a forest preserve to benefit from nature—sometimes even a houseplant or the smell of lavender can improve our life. Kathy Willis, a professor of biodiversity at the University of Oxford, joins host Rachel Feltman to discuss her new book Good Nature: Why Seeing, Smelling, Hearing, and Touching Plants Is Good for Our Health. Willis suggests ways for even city dwellers to reap the benefits of nature, such as strolling through urban parks or keeping plants in their office.

Ashleigh Papp, an animal scientist turned storyteller, shifts our perspective on the modern conservationist. With low wages and expectations of free work, conservation science lacks diversity as a field—but dedicated graduate students and new programs are trying to change that. Isaac Aguilar, a graduate student in the geology division at the California Institute of Technology, tells Papp about his journey into conservation. Plus, join a night patrol with crime prevention sergeant Malungane Naledi. She's a member of the Black Mambas, an all-woman anti-poaching unit in South Africa’s Greater Kruger National Park.

This is part three of The New Conservationists, a four-part series about the evolving world of animal conservation.

Listen to part one and part two.

Ashleigh Papp, an animal scientist turned storyteller, takes us on into the field. Conservationists and animal behaviorists were once restricted to wildlife data gathered manually. Now new technologies are expanding the amount of passively collected data—and machine learning is helping researchers cut through the noise.

This is part two of The New Conservationists, a four-part series about the evolving world of animal conservation.

If you were intrigued—or disturbed—by the artificial intelligence podcast on your Spotify Wrapped, you may wonder how AI audio works. Audio Overview is a feature of the tool NotebookLM, released by Google, that allows for the creation of short podcasts with AI “hosts” summarizing information. But questions remain about the accuracy, usefulness and environmental impacts of this application. Host Rachel Feltman and associate news editor Allison Parshall are joined by Google Labs’ editorial director Steven Johnson and AI researchers Anjana Susarla and Emily Bender to assess the promise of this buzzy tech.

Low iron levels can cause fatigue and impact mental health, but doctors often miss cases of iron deficiency and anemia. Pediatric hematologist Angela Weyand, a clinical associate professor at the University of Michigan Medical School in Ann Arbor, points to one population that could be at a higher risk—young women with heavy menstrual bleeding. In one study from a national database, nearly 40 percent of otherwise healthy adolescent women were iron-deficient, and 6 percent were additionally anemic. Awareness and self-advocacy could help people receive accessible and inexpensive treatments for low iron levels.
