Dr. Stacey Tecot – What can lemur hormones tell us about infant caregiving?

Dr. Stacey Tecot of the University of Arizona joins the show to talk about her research on lemurs, their endocrinology and what their hormones can tell us about allomaternal care -- the care provided to young by any individuals who are not the mother.

Dr. Raquel Fleskes of Dartmouth joins the show to talk about her work using ancient DNA to uncover the past in the Tidewater and South Carolina. Most people think about ancient DNA being used for, well, ancient skeletons, but ancient DNA can also be used in more recent contexts to illuminate the near past. We also chatted about ways to make ancient DNA work more accessible to descendent communities.

Ron Romano of Spirits Alive (a non-profit dedicated to preserving Eastern Cemetery and its history) joins the show to talk about gravestone symbolism, mortuary practices, cemetery organization and social status, and the evolution of gravestone creation in Eastern Cemetery of Portland, ME. Cemeteries reveal a lot about the people who made them -- how they think about death, life, and religion; social and economic hierarchies; changing technologies; what's important to them; what causes anxiety. Cemeteries are human-made spaces filled with our bodies and artifacts that we've created. They can't help but be reflections of who we are and what we care about in any particular moment. Historians like Ron help us unpack these layered contexts by using the cemetery as a lens for interpretation of the past.

Dr. Wakefield (Northeast College) and Dr. Neidich (University of Missouri) joined the show to discuss their research on death in early New York mental health institutions and how it differed from the populations around them. Along the way, we talk about the history of mental health institutions in the United States and how differences in the amount and causes of death can illuminate what we care about as a society.
