While the daily rhythmicity of organisms is entrained by several cues, light is thought to be the strongest signal. Surprisingly, a new study in a moth shows that olfactory communication can be even more powerful for synchronization, and, at least to some extent, works across related species.

Sexually dimorphic dopaminergic circuits determine sex preference.

Sociosexual preference is critical for reproduction and survival. However, neural mechanisms encoding social decisions on sex preference remain unclear. In this study, we show that both male and female mice exhibit female preference but shift to male preference when facing survival threats; their preference is mediated by the dimorphic changes in the excitability of ventral tegmental area dopaminergic (VTA) neurons.

Background: Since the mid-2010s, slamsex-sexualized drug use involving intravenously injecting meth-has rapidly emerged in metropolitan gay communities as a sociosexual practice necessitating harm reduction interventions. However, its impact on gay men's sociosexual lives and HIV technologies is not well understood. This paper addresses this gap by investigating two intertwined temporal dimensions of slamsex, viewing it as a form of slow edgework in post-AIDS Taiwan.

Socially induced plasticity in reproductive effort is a widely documented phenomenon. However, few empirical studies have examined how male and female plastic responses to the social environment might interact in determining fitness outcomes. In field crickets, Teleogryllus oceanicus, males respond to rival songs by increasing expenditure on seminal fluid proteins that enhance competitive fertilization success at the cost of reduced embryo survival.

Since Darwin, many evolutionary and behavioral researchers have considered the role of phenotypic traits that favor the domestication of nonhuman animals. Among such proposed traits are a species' social structure, level of intra- and interspecific agonistic interactions, sociosexual behaviors, parental strategies, reaction to humans, habitat preference, dietary habits, developmental trajectories, and utility to humans. However, little to no comparative phylogenetic evidence exists concerning the importance of these attributes for the domestication of animals.

Sociosexuality-attitudes, behaviors, and desires related to casual sex-partly predicts drinking behavior in both men and women because drinking is thought to facilitate interactions that lead to casual sex. It follows that sociosexuality would predict drinking intake (e.g.
