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