Diagnosing confounded Bateman gradients
Abstract. The Bateman gradient is a fundamental metric of sexual selection, often interpreted as the fitness advantage individuals gain by increasing their

How to interpret sexual selection using Bateman gradients? When are these not informative & how should researchers identify, deal with confounded gradients? We simulate anisogamy & sperm competition to provide a guide for using Bateman gradients. Out in Evolution

Loss of the Y chromosome in some cells increases with age in men and is associated with higher risks of cardiovascular disease, cancer, and reduced lifespan. Environmental factors may also contribute. doi.org/hbpgfc
Men lose their Y chromosome as they age: Scientists thought it didn't matter—but now we're learning more
Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health.
