First this week, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to discuss the paradox of metabolically healthy obesity. They chat about the latest research into the relationships between markers of metabolic health—such as glucose or cholesterol levels in the blood—and obesity. They aren’t as tied as you might think.

Next, Colin Dayan, professor of clinical diabetes and metabolism at Cardiff University and senior clinical researcher at the Wellcome Centre for Human Genetics at the University of Oxford, joins Sarah to discuss his contribution to a special issue on type 1 diabetes. In his review, Colin and colleagues lay out research into how type 1 diabetes can be detected early, delayed, and maybe even one day prevented. Finally, in the first of a six-patrt series of book interviews on race and science, guest host Angela Saini talks with author and professor of history at the University of Massachusetts, Amherst, Samuel Redman, about his book Bone Rooms: From Scientific Racism to Human Prehistory in Museums. The two discuss the legacy of human bone collecting and racism in museums today.
