Testosterone administration modulates inequality aversion in healthy males: evidence from computational modeling.

Fairness concerns play a prominent role in promoting cooperation in human societies. Social preferences involving fairness concern have been associated with individual testosterone levels. However, the causal effects of testosterone administration on fairness-related decision making remain to be elucidated.

Construction of a BC-based TM single-atom catalyst for efficient reduction of CO to CH: a computational study.

The electrocatalytic conversion of CO into fuels or chemicals presents an effective approach to mitigate greenhouse gas emissions and address the traditional fuel crisis. Based on density functional theory, we systematically investigate a series of transition metal atoms bound to a BC monolayer as novel single-atom catalysts (SACs) for the CO reduction reaction (CORR). Our results demonstrate that most of the constructed SACs exhibit superior selectivity for the CORR over the hydrogen evolution reaction, with CH as the dominant product.

Estratetraenol increases preference for large sexual reward but not impulsivity among heterosexual males.

There is increasing evidence suggesting that estratetraenol, a human chemosignal deemed a putative sex pheromone, affects social cognition and sexual behavior. The present study investigates the effects of estratetraenol on preference for sexual rewards in heterosexual males. Seventy-six male participants received either estratetraenol or a control carrier in a double-blind, placebo-controlled, within-participant design.

Exogeneous testosterone increases sexual impulsivity in heterosexual men.

Testosterone has been hypothesized to promote sexual motivation and behavior. However, experimental evidence in healthy humans is sparse and rarely establishes causality. The present study investigated how testosterone affects delay of gratification for sexual rewards.

design of single transition metal atom anchored defective boron carbide monolayers as high-performance electrocatalysts for the nitrogen reduction reaction.

Development of low-cost and high-efficiency single atom catalysts (SACs) is essential for catalyzing nitrogen reduction reactions (NRR) under ambient conditions. Current SACs suffer from low selectivity and poor activity, making it hard for them to meet the requirements of industrial applications. Here, we present a graphene-like BC monolayer as a substrate for single metal atoms.

Testosterone reduces generosity through cortical and subcortical mechanisms.

Recent evidence has linked testosterone, a major sex hormone, to selfishness in economic decision-making. Here, we aimed to investigate the neural mechanisms through which testosterone reduces generosity by combining functional MRI with pharmacological manipulation among healthy young males in a double-blind, placebo-controlled, between-subject design. After testosterone or placebo gel administration, participants performed a social discounting task in which they chose between selfish options (benefiting only the participant) and generous options (providing also some benefit to another person at a particular social distance).

Exogenous testosterone decreases men's sensitivity to vocal cues of male dominance.

Assessing dominance is important for effective social interactions, and prior research suggests that testosterone is associated with men's dominance perceptions. The present study tested for a causal effect of exogenous testosterone on men's sensitivity to vocal cues of other men's dominance, an important parameter in male-male competition across species. One hundred and thirty-nine Chinese men received a single dose (150 mg) of testosterone or placebo gel in a double-blind, placebo-controlled, between-participant design.

Exogenous testosterone increases the audience effect in healthy males: evidence for the social status hypothesis.

Several studies have implicated testosterone in the modulation of altruistic behaviours instrumental to advancing social status. Independent studies have also shown that people tend to behave more altruistically when being watched (i.e.
