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.

Oxytocin, but not the structurally similar vasopressin, modulates both the chemosensory decoding of femininity in straight men and that of masculinity in gay men in an inverted-U-shaped manner.

Pulsatile chromatin opening stimulated by naturally-occurring plasma growth hormone pulses is one of two GH-determined mechanisms that establish widespread sex differences in hepatic chromatin accessibility and epigenetic regulation, both closely linked to sex differences in liver gene transcription and function.

There may be as many ways to think about the experience of women in science as there are women in science.

Identifying why statins differ from other major lipid modifiers has revealed a new modifiable target of intervention for cardiovascular disease relevant to both drug development and optimal statin use.

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

Social hierarchies resulting from the European colonization of the Americas stratified the population structure, leading to ancestry-related assortative mating and sex bias patterns that can be inferred from the genomes of the populations across the continent.

The courtship master gene fruitless tunes functional flexibility of courtship circuitry during development instead of switching on its function as conventionally viewed.

Measurement precision offers a comprehensive perspective on good scientific practices to improve reproducibility of research results by providing means to optimize design and analysis parameters (e.g. sample size, trial count, or sample heterogeneity) in accordance with the researcher’s goals.
