A study found that social closeness, rather than physical proximity, determines if a bystander consoles a victim. Human adults were more likely to console victims based on gender and the threat level of the situation. These findings suggest that humans may be motivated to console their peers out of empathy, similar to chimpanzees.
Research reveals that mating stimulates aggression in female fruit flies, making them more intolerant of others and changing their behavior, including increased ovulation and rejection of male advances. The study's findings have implications for understanding female competition and potentially controlling pest insect populations.
Children's rejection is influenced by the interpretations of others rather than their behavior. A new study found that the reasons behind rejection often stem from the rejecters' perceptions, such as fear or mistrust.

Males with heart rates one standard deviation below the mean or lower had nearly three times the odds of having engaged in stalking compared to other participants.
Research found that hermit crabs living in broken shells are more aggressive and fight at a higher intensity than those with intact shells, compensating for their apparent disadvantage. This is attributed to the 'resistance training' of carrying heavy, unusable parts of the shell.
A study by Aarhus BSS at Aarhus Universit found that people who perceive the world as conflict-ridden and are predisposed to aggressive behavior are more likely to support dominant leaders. This support is driven by a desire to escalate conflicts aggressively rather than fear or new situations.

A new study found that children with disabilities are more likely to respond aggressively when bullied, leading to negative mental health outcomes. Teaching proper bully-response skills is crucial to prevent such aggressive behavior and improve psychosocial outcomes for these students.
Researchers found that teens are more likely to be bullied by current or former friends and dating partners than by strangers. Close relationships can lead to intense competition for status and esteem, resulting in cyber aggression.
A new study found that youth cyberbullying is most common between current or former friends and dating partners, with approximately 17.2% of students experiencing cyberbullying within a week. Girls were twice as likely to fall victim to cyber aggression than boys, while LGBTQ youth were four times more likely to be victims.
A new study by Joyce Benenson found that men are more likely to engage in friendly physical contact after competition than women. This finding supports the 'male warrior hypothesis,' which suggests that males broker good feelings after conflict to ensure they can call on allies to defend their group.

Male cuttlefish exhibit a hierarchy of threat displays to signal aggressive intent, with frontal and shovel displays predicting subsequent lateral displays. These displays allow rivals to determine the opponent's level of aggression, enabling tactical decisions about contest escalation or withdrawal.
Researchers found that diverse spider societies composed of both docile and aggressive spiders are more resilient to temperature fluctuations than those with a single personality. This discovery has implications for restoring animals in changing habitats.

The researchers tested how facial patterns influence behavior and hormone levels in paper wasps, revealing a complex relationship between honesty and evolutionary fitness.
Research found that female bonobos' unreliable sexual swellings make it difficult for males to time their mating efforts accurately. This may reduce aggressive mate competition and result in bonobo societies being more peaceful. The study advances understanding of the evolution of sexual signaling in our closest relatives.
The CLASH model suggests that hot climates with less temperature variation lead to a faster life strategy, less focus on the future, and less self-control, contributing to more aggression and violence. Researchers believe their model can help explain the impact of climate on rates of violence in different parts of the world.
Researchers have developed a new model called CLASH that suggests hot climates with less seasonal variation lead to more aggression and violence. This is due to a faster life strategy, reduced focus on the future, and decreased self-control, resulting in quicker reactions and increased aggression.
Research found that women rate male body odor femininity decreases with application of deodorant. Men who were initially perceived low in masculinity significantly increased their odour masculinity after applying a deodorant.

New research analyzed data from over 68,000 women with breast cancer registered in England between 2006-2013. The study found that average age at diagnosis was lower in both South Asian and Black women than in White women. Ethnic minority women may still face larger tumours and more aggressive features despite younger age.
Researchers found that physical strength is a key attribute in judging leadership potential, with strong men perceived as better leaders and having higher status. This effect does not depend on physical attractiveness, and even manipulating body size and height had no impact on participants' ratings.
Maladaptive and impulsive aggression is a disabling symptom in children with psychiatric disorders, characterized by explosive behavior triggered by routine cues. The development of effective treatments requires better descriptive and quantitative methods to characterize this disorder.
A Rutgers study found that prepubescent female rodents paired with sexually experienced males exhibited elevated stress hormones, reduced learning capabilities, and decreased maternal behaviors. This research sheds light on the consequences of sexual aggression in females, which is crucial for understanding its impact on women's mental...
A study in mice reveals that changes in the lateral septum, a brain structure tied to anxiety and fear control, trigger 'septal rage' - sudden, violent outbursts. The research may lead to better understanding of aggression in other animals, including humans.
A study by SF State researchers found that individuals experiencing anger, contempt and disgust are more likely to act aggressively towards those they disagree with. The study suggests that identifying the specific emotional mix that leads to aggression can help prevent hostile behavior.
