Sausage Of Science

Cecilia Padilla Iglesias estudió Ciencias Humanas y de la Evolución en University College de Londres, donde empezó a interesarse por cómo surgió y cambió la diversidad cultural y biológica en nuestra especie. Hizo un máster en Antropología Evolutiva en Cambridge y luego un doctorado en la Universidad de Zúrich sobre cómo los cambios ecológicos y sociales han moldeado la dinámica de las poblaciones humanas. Durante el doctorado pasó varios meses en la República del Congo trabajando con comunidades nómadas de cazadores-recolectores. Hoy trabaja en Cambridge con una beca de investigación, estudiando cómo la vida nómada y la movilidad se reflejan en el genoma de estas poblaciones. La idea central de su trabajo es que la movilidad ha sido clave para la resiliencia de los humanos durante cientos de miles de años, y que fue lo que permitió adaptarse a enormes cambios ecológicos y demográficos en los diferentes ecosistemas que fue habitando. ------------------------------ Encuentra el trabajo comentado en este episo

Lawrence M. Schell is a Distinguished Professor in the Department of Anthropology and the College of Integrated Health Sciences at the University at Albany, SUNY, with a joint appointment in the Department of Epidemiology and Biostatistics. His research explores the interrelationship between biology and culture, with a particular focus on how contemporary urban environments shape human health and development. Dr. Schell’s early work examined noise as a form of urban stress, investigating its effects on prenatal and postnatal growth. He later expanded his research to include pollutants such as polychlorinated biphenyls (PCBs) and lead, situating these exposures within the broader context of urban adaptation and health disparities. The study of lead exposure in Albany, NY, examined its influence on child physical and cognitive development, with attention to maternal nutrition and other factors that affect the transfer of lead from mother to fetus. In partnership with the Akwesasne Mohawk Nation he has recently

This week on The Sausage of Science, Chris and Cristina explore pica (the craving and consumption of nonfood items like earth or clay) through the lens of maternal health and nutrition. Our guest, Dr. Leila Larson of the University of South Carolina, shares insights from her study on pica among pregnant women in Malawi, part of the REVAMP iron supplementation trial. She discusses how iron status, infection, and environment influence maternal health, why intravenous iron may be a more effective approach to reducing pica, and what these cravings reveal about nutrition and development worldwide. We also hear about her new U.S.-based study and how she balances a vibrant global research career. ------------------------------ Find the work discussed in this episode: Larson, Leila M., Martin Mwangi, Rebecca Harding, Ernest Moya, Ricardo Ataíde, Glory Mzembe, Ashley Thurber et al.

With a background that bridges the humanities and sciences, a PhD in the History of Consciousness from UCSC, and a postdoctoral fellowship in Anthropology at Stanford, Josh brings a truly interdisciplinary lens to understanding what happens when people reach for the divine, and how those moments transform the body and mind alike. ------------------------------ Find the book discussed in this episode: Tongues of Fire: How Charismatic Prayer Changes Evangelical Brains and Mobilizes Spirit-Filled Ac

Alex got her degree from the University of Notre Dame in 2022 after finishing her dissertation on the variation in brown adipose tissue thermogenesis and its effects on metabolic health markers in adults from Samoa. She is currently a postdoctoral fellow at Pennington Biomedical Research Center working on the Military Health and Nutrition Examinations Study (MHANES) (PI: Dr. Claire Berryman). In collaboration with the US Army Research Institute of Environmental Medicine, her work with MHANES examines how the interactions between environmental (i.e. temperature, altitude), behavioral (i.e. physical activity, nutrition, sleep), and physiological (i.e. body composition, energy expenditure, metabolic health markers) factors affect health and performance in active-duty service members. She frequently collaborate with colleagues on anthropological research projects focusing on the effects of physiological adaptations/adjustments to the extremes and is passionate about bringing anthropological perspectives to clinic

This week on the Sausage of Science, Cara sits down with two trailblazing scholars shaping the future of paleoanthropology from the African continent outward. Dr. Palesa Madupe, postdoctoral researcher at the University of Copenhagen’s Globe Institute, shares her pioneering work on enamel proteomics—reconstructing protein sequences from Paranthropus robustus and other South African hominins to unravel questions of taxonomy, sex determination, and sexual dimorphism. Joining her is Professor Becky Ackermann of the University of Cape Town, co-director of the Human Evolution Research Institute (HERI), whose influential research on evolutionary processes, phenotypic variation, and human diversity is reframing our understanding of our evolutionary story. Together, they highlight how African-led research is reshaping the global narrative of human origins, one fossil and one protein at a time. ------------------------------ Find the paper discussed in this episode: Madupe, P.
