Scientists discovered that female brain structures change monthly in response to hormonal fluctuations, particularly the hippocampus which plays a crucial role in memories and emotions. The study aims to better understand premenstrual dysphoric disorder (PMDD) by examining the brain's monthly rhythm.
Researchers found that a single white-browed coucal parent can successfully raise its brood, unlike black coucals which form pairs and share parental duties. The study suggests that females only form pairs due to lack of opportunities to find additional male partners.
A study by Duke University and Max Planck Institute reveals that chimpanzees, bonobos, and orangutans can understand when others have mistaken beliefs, mirroring skills seen in human infants. The apes' ability suggests a key step towards fully understanding the thoughts of others.
Researchers found asymmetrical power encourages extortionate behavior in a model and experimental setup, with subordinates better off playing along. Extortionists succeed only if they maintain a well-measured degree of friendliness.
In emergency situations, people tend to behave either egotistically or prosocially, with some individuals being more cooperative than others. A study published in Nature Scientific Reports found that most participants helped others less in emergency situations due to time pressure, while prosocial individuals were more willing to help.
