Peruvian hairless dogs—a medium-sized elegant Indigenous breed with pointy ears—are widely represented in ancient Andean coastal pottery. Celebrated as a national symbol, they were declared part of Peru's cultural heritage in 2000. A new study published in the Journal of Anthropological Archaeology examining dog skeletal remains and a mummified dog, provides the first physical evidence of Peruvian hairless dogs from the only Wari Empire site found to date, on the coast of northern Peru, known as Castillo de Huarmey. 

Hormones influence the behavior of cells in the brain, including areas of the brain that process hearing, and scientists have begun recognizing differences between the sexes and their effects on health outcomes. In simple hearing tests, men show an earlier, more gradual decline, while women experience regular fluctuations each month during menstruation and sharp changes at menopause. Anhelina Bilokon from the University of Maryland will present work related to sex-dependent auditory variability as part of the 190th ASA Meeting.
