First up on the podcast, Staff Writer Meredith Wadman joins host Sarah Crespi to discuss recent advances in understanding endometriosis—a disease where tissue that resembles the lining of the uterus grows outside the uterus, causing pain and other health effects. The pair talk about how investigating the role of the immune system in this disease is leading researchers to new potential diagnostic tools and treatments.   Next on the show, why are there good dengue years and bad dengue years? This week in Science Translational Medicine, Talia Quandelacy and colleagues map the synchrony and spread of this mosquito-borne disease in Latin America. She joins the podcast to talk about how the seasons, rainfall, and even El Niño connect with dengue levels and how this understanding can help with prediction and preparation.   Quandelacy is an assistant professor in the department of epidemiology at the University of Colorado School of Public Health.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Meredith Wadman Learn more about your ad choices.
