New research suggests that high fructose intake may drive aggressive behaviors, ADHD, and bipolar disorder by triggering a foraging response. This process, meant for survival during starvation, can lead to impulsive behavior in excess sugar intake.
Two 14-year longitudinal studies found that people with disagreeable personality traits, such as being combative and manipulative, are not more likely to achieve power than those who are nice. In contrast, extroverts were the most likely to advance in their organizations based on sociability, energy, and assertiveness.
Researchers found that individuals with disagreeable personalities exhibit high levels of dominant behavior, which enhances their power. However, this is offset by lower generosity and willingness to help others, diminishing their power.
A new study reveals that differentiation of a single gene changes behavior in a wild songbird, determining whether the bird displays more or less aggression. The research identifies a specific estrogen receptor as driving this behavior, showing how genomic divergence can lead to behavioral divergence in a vertebrate.

A new study found that higher birthweight is associated with better cognitive and socioemotional outcomes in preschoolers, particularly for those from lower-income families. Weighing more than a twin at birth may predict greater school readiness and improved behavior.
A University of Guelph study found that fruit flies' aggression depends on their previous interactions, not just who they're interacting with. The study showed that males in certain social groups became more aggressive after one-on-one encounters.
A University of Guelph study reveals that fruit flies' aggression is shaped by past interactions, not just who they interact with. The findings suggest that aggression is a complex trait influenced by social experiences, and its effects can last for up to three days.
A Duke University study found that female lemurs' aggression may be programmed in the womb due to high levels of androstenedione. Females exposed to higher doses of this hormone during pregnancy grow up to be more aggressive as adults.
Research at a bonobo community found that female-female sex increased oxytocin levels, promoting social bonding and cooperation. This suggests that same-sex interactions may play a crucial role in maintaining high levels of cooperation among female bonobos.

A new study by the American Psychological Association finds that men with sexist attitudes may underestimate their power in relationships, leading to more aggressive behavior. The research suggests that this can create a vicious cycle, reinforcing stereotypes and damaging relationships.
A recent study from North Carolina State University found that students with strong family relationships are more likely to intervene when witnessing bullying. Good teacher relationships also play a crucial role in encouraging bystander intervention. In contrast, those who feel excluded or discriminated against by peers or teachers are...

A new study from the University of Washington found that consistent hours, regardless of time of day, can give families flexibility and in some cases, improve children's behavior. The study examined two-parent households with one parent working nonstandard shifts and found that rotating or split shifts were associated with more behavio...
Researchers found that parents' explanations of how peers interact help young children view their peers' behavior with less hostility. Framing social situations in a positive way can reduce the likelihood of aggressive behavior.
A Journal of Neuroscience study found that a transcription factor called FosB plays a key role in regulating aggressive behavior in mice. Increased FosB levels were linked to increased aggression intensity and dominance.
A study found that aggressive mice showed increased dominance and aggression when ΔFosB was overexpressed, suggesting a link between this protein and violent behavior. The research suggests targeting ΔFosB may reduce aggression by modifying the brain's reward system.
Researchers at Karolinska Institutet discovered a previously unknown group of brain cells responsible for initiating and organizing aggressive behavior in mice. By stimulating or inhibiting these cells, the team was able to control aggression and even invert hierarchical status between dominant and submissive males.
Researchers found that social isolation in mice upregulates neuropeptide Tac2/NkB, leading to increased aggression and persistent responses to threatening stimuli. The peptide is overproduced in multiple brain regions, causing diverse behavioral changes that persist even after social isolation is reversed.

A study found that male ring-tailed lemurs' stink-flirting displays may influence females in choosing a mate and could be an alternative mating strategy, despite being met with aggression and potential physical harm.
A two-week intervention program focusing on reducing risky behavior was found to be effective in reducing aggression and future incarceration rates among clinically aggressive juvenile offenders. The program, PHAT Life, taught youth to identify triggers for high-risk behavior and develop coping strategies.
Researchers found that abusive supervisors experience a sense of recovery from their behavior, which helps replenish mental energy and resources. However, this benefit is short-lived, lasting only a week or less, after which they start to experience decreased trust, support, and productivity from employees.
A new IUPUI study found that juveniles who perceive police injustice are more likely to engage in aggressive behavior, particularly those who justify immoral actions. Intervention programs addressing perceptions of police injustice and moral disengagement may help reduce aggression among youth involved in the juvenile justice system.
A new study published in Archives of Sexual Behavior found that men and women with square faces tend to have a stronger sex drive, are more likely to engage in casual sex, and report higher levels of sociosexuality. Researchers attribute these findings to variations in testosterone levels during puberty.
Researchers found that female mice brain structures organize sex and aggressive behavior differently, with separate cell groups controlling each. In contrast, male mice brain circuits overlap in controlling both behaviors, suggesting a fundamental difference in brain organization between sexes.
