Students with higher levels of academic competence and female students were more likely to be recognized by both groups. The study suggests that better identification of these students is crucial for effective interventions.
A recent study found that men were twice as likely to be victims of online sex blackmailing during the pandemic. Young people, Black and Native American women, and LGBTQ individuals were also at high risk of this cyber-enabled crime. The study revealed race and sexuality-related differences in rates of sextortion.

The researchers hope to learn more about what hippos communicate through their calls, exploring how they recognize sounds and whether voices reveal characteristics like size or sex.
A study by the University of Exeter found that older male elephants help keep younger, more aggressive males calm by policing their behavior. Without these older bulls, adolescent elephants become more fearful and aggressive towards non-elephant targets, posing a threat to humans.
In meerkat societies, testosterone-driven aggression enables cooperative breeding by creating a hierarchy where subordinates help raise the matriarch's pups. Researchers found that matriarchs' high testosterone levels drive their aggressive behavior, which maintains group structure.
