Researchers found that students with high math and moderate verbal abilities were more likely to pursue STEM careers,...
A new study suggests that mindfulness can help overcome barriers to self-knowledge, including blind spots in thinking, feeling, and behaving. By increasing bodily awareness, mindfulness may reduce emotional reactivity and improve our ability to see ourselves more accurately.
A new study suggests that our experiences of space and time have more in common than previously thought, with people perceiving the future as closer to the present. The researchers found that a temporal Doppler effect occurs when movement through space is toward the future, making it feel closer to the present.
A new study found that infants prefer individuals who are nice to people like them and mean to people who aren't like them. This preference is present in infancy and helps form social bonds but can also lead to mistreating others who are different.

A pilot study shows that qigong therapy significantly reduced cocaine cravings and depression symptoms in individuals undergoing residential substance abuse treatment. This promising treatment approach may have profound consequences in drug rehabilitation programs.
A study published in Journal of Eating Disorders found that women's conversations about weight, known as 'fat talk,' were more prevalent during younger years. In contrast, discussions about aging, or 'old talk,' increased with age and were less frequent. Women who engaged in both types of talk tended to have a more negative body image.
A new study published in Environmental Science & Technology found that approximately 60% of the world's population lacks access to improved sanitation. This deficiency is attributed to inadequate sewage treatment and can lead to disease, highlighting the need for better global health standards.
Researchers studied how couples cope with child loss and found that suppressing emotions can worsen grief. The study suggests that clinicians should guide clients away from 'staying strong' for partners to ease their suffering.
Research by Priyanka Joshi and Nathanael Fast found that powerful individuals are more willing to take larger rewards in the future due to feeling a stronger connection with their future selves. This reduction in temporal discounting allows them to make better, long-term decisions.
