… Heidi Fisher and Hopi Hoekstra show that when the sperm of two deer mice species are
mixed, they aggregate preferentially with sperm from their own species. In mixtures between …

Sperm cells of all taxa share a common goal to reach and fertilize an ovum, yet sperm are
one of the most diverse cell types in nature. While the structural diversity of these cells is well …

Human ability to resolve temporal variation, or flicker, in the luminance (brightness) or
chromaticity (color) of an image declines with increasing frequency and is limited, within the …

Natural hybrid zones provide opportunities to study a range of evolutionary phenomena
from speciation to the genetic basis of fitness‐related traits. We show that widespread …

Centrioles are subcellular organelles found at the cilia base with an evolutionarily conserved
structure and a shock absorber-like function. In sperm, centrioles are found at the flagellum …

Sperm cooperation has evolved in a variety of taxa and is often considered a response to
sperm competition, yet the benefit of this form of collective movement remains unclear. Here, …
