In many species, males can make rapid adjustments to ejaculate performance in response to sperm competition risk; however, the mechanisms behind these changes are not understood.Here, we manipulate male social status in an externally fertilising fish, chinook salmon (Oncorhynchus tshawytscha), and Tools find that in less than 48 hr, males can upreg
Abstract Introduction Point-of-care ultrasound (US) is used in clinical practice across many specialties.Ultrasound (US) curricula for medical students are increasingly common.Optimal timing, structure, and effect of ultrasound education during medical school remains poorly understood.This study aims to retrospectively determine the association bet
Background: Women report higher rates of trauma-related disorders compared to men.With women being disproportionately impacted by the consequences of natural hazards, this gender disparity may increase in their aftermath.Objective: This meta-analysis aimed at quantifying gender gaps in mental disorder prevalence following natural hazards, consideri
While more than 70 genes have been linked to deafness, most of which are expressed in mechanosensory hair cells of the inner ear, a challenge has been to link these genes into molecular pathways.One example is Myo7a (myosin VIIA), in which deafness mutations affect the development and function of the mechanically sensitive stereocilia Mushroom Gumm
