Research found a 3% decrease in assaults on Mondays after the start of Daylight Saving Time, challenging previous assumptions about sleep deprivation's impact on crime. The study suggests that increased sleep may be associated with more offending behavior, but internal biases and short-term effects are likely causes.

The researchers analyzed data from New York City's NYPD during a period when proactive policing was halted, revealing a 3-6% decrease in reported serious crimes.
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 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.

Research by Jessica Purcell and colleagues found that individual spiders can outlast their group counterparts when introduced to a new environment. The study suggests that adaptation to local traits is key to survival, rather than individual personality types.
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.
A relational aggression prevention program for urban girls improves overall classroom climate, with benefits extending to boys and teachers. The program, Friend to Friend (F2F), teaches problem-solving, anger management strategies, and leadership skills.
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.
A new study found that men tend to be more aggressive in messaging users on dating websites, sending multiple messages to attractive females. In contrast, women are more self-conscious about their own attractiveness and evaluate the likelihood of getting a response from potential matches.
Researchers found that older female bonobos form coalitions to attack and defeat aggressive males, helping younger females maintain social status. This coalition-forming behavior allows young females to join the group without fear of male harassment.

A study found that paper wasps aggressively punish dishonest signals, leading to reduced hormone levels and long-term impacts on social interactions. 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.
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.
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.
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.
Researchers identify mutation in ATP4a gene responsible for aggressive form of inherited gastric NET. Restoring normal gastric acid balance with hydrogen chloride solution prevents tumour development in genetically engineered mice.

The study found that IED patients are more than twice as likely to have been exposed to the para...
A new study has identified a significant link between intermittent explosive disorder and exposure to the common toxoplasma gondii parasite. Individuals with IED were found to be twice as likely to have been exposed to toxoplasmosis, which is typically carried by undercooked meat or cat feces.
A recent study published in the American Journal of Human Biology found that cortisol levels increase with aggressive behavior in 10-year-old boys. Cortisol is not associated with increased aggression in girls during this age range.
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.
