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

Listen to part one, part two and part three.

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.

Donald Trump has nominated RFK, Jr., to run the Department of Health and Human Services, a position that includes oversight of the Centers for Disease Control and Prevention, the Food and Drug Administration and the National Institutes of Health. Senior health and medicine editor Tanya Lewis explains what that would mean for antivaccine policies, food safety and unproven therapies that Kennedy backs. Tobacco use is down across the U.S., but the drop has been uneven across groups. Astronomers have released the first-ever close up image of a star—and scientists are excited over an unexpected ring. Plus, studies of chimpanzees explore the role of social contagion on their behaviors and point to play in adult chimps.

Writings and records are how we understand long-gone civilizations without being able to interact with ancient peoples. A recent opinion paper suggested we could feed chatbots writings from the past to simulate ancient participants for social psychology studies. Similar survey experiments with modern participant data closely matched the outcomes of the real people they were based on. We speak with the opinion paper’s co-author Michael Varnum, an associate professor at Arizona State University, about what the limits of this spooky proposal are and what the ghosts of cultures past could teach us today.
