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.

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.

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.

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.  Recommended reading: “Large Language Models Based on Historical Text Could Offer Informative Tools for Behavioral Science,” by Michael E.

Disparities in health are not indicated by adverse outcomes alone. Adriana Corredor-Waldron, an assistant professor of economics at NC State University, sought to understand why Black infants are more likely to be delivered by C-section than white infants. A working paper she co-authored found that the elevated number of low-risk Black pregnant people who were given C-section surgeries in New Jersey from 2008 to 2017 was likely caused by physician discretion. Corredor-Waldron explains why unnecessary C-sections can be risky and what medical education and financial incentives could do to close the gap.  Recommended viewing: What Is Implicit Bias, and How Might It Affect Your Next Medical Visit? https://www.scientificamerican.com/video/what-is-implicit-bias-and-how-might-it-affect-your-next-medical-visit/  E-mail us at sciencequickly@sciam.com if you have any questions, comments or ideas for stories we should cover!
