The quantification of sexual selection reveals that it is important to consider the chosen time frame of measurement as well as the sexual system.

A longer birdsong-learning window evolves in response to sexual selection for song complexity and is associated with faster evolution of song performance characteristics.

An NMR-based structural study of sperm proteins reveals a novel protein packaging/dispersion system embedded in a coevolutionary arms race.

While men’s mating success is predicted both by their strength/muscularity, voice pitch, height, and testosterone levels, their reproductive output is only predicted by strength/muscularity.

Identification of central neural circuits and sensory pathways underlying social-sexual modulation of sperm ejection in female Drosophila unraveled cryptic mate choice, a mechanism of post-copulatory sexual selection.

Selection for asymmetric signalling between gametes explains the very origins of sexual asymmetry as seen in mating-types with morphologically similar but self-incompatible gametes.

The discovery of a biological switching valve provides an example of a mechanism that evolved in nature long before its invention by man and could inspire alternative valve technologies.

Computational analyses, for the first time in plants, reveal how male-biased genes evolve faster than female-biased and unbiased genes.

Comparative study provides evidence that males are under stronger total selection compared to females.

A novel form of self-fertility evolved in Cryptococcus depauperatus, a close relative to the human pathogenic Cryptococcus species, in which sexual development is attained by self-signaling of a cognate pheromone and pheromone-receptor pair.
