A groundbreaking study suggests that Parkinson’s disease may begin in the kidneys, where a toxic protein builds up and travels to the brain. This discovery could reshape our understanding of the disease’s origins and risk factors.

Lower diversity in the oral microbiome was linked to higher depressive symptoms in a large U.S. sample, with especially strong associations among men and non-Hispanic Whites. Differences in microbial composition were also observed between depressed and non-depressed individuals.

A new study from Lebanon finds that people with authoritarian beliefs tend to oppose violence against political leaders, while those high in social dominance orientation are more likely to support violence against rival group members.

Experienced FPS players showed faster aiming execution and more efficient eye movement patterns, especially a single-saccade strategy, compared to non-players. Their advantage persisted across different distances and timing conditions, suggesting enhanced visual-motor coordination under pressure.

A new study published in the Journal of Psychoactive Drugs suggests that while awe can be transformative during ayahuasca retreats, there’s a limit. Experiences marked by excessive vastness were linked to lower well-being, challenging assumptions about awe’s universal benefits.

Touch-related sensory decline could offer early clues to cognitive problems, according to a recent review. The findings point to tactile impairments as possible predictors of memory loss and dementia, offering new directions for early detection and prevention.

Specifying a child’s race alters how adults perceive their awareness of race and racism, according to new research. Black children are viewed as less “color-evasive” and more racially aware at earlier ages than White children or generic “children.”

Parental bonding may influence happiness well into adulthood, according to a new study. Italian researchers found that overprotective parenting predicted greater anxiety, while caring parenting supported healthier anger control—both of which played roles in shaping overall life satisfaction.

A new study shows that individuals with higher psychopathic traits are less likely to punish unfair behavior, especially when it costs them personally. The research suggests self-interest, not a lack of moral understanding, drives their reluctance to enforce social norms.

Why do people cry happy tears? Neuroscience suggests these emotional outbursts occur when the brain becomes overwhelmed by joy, nostalgia, or relief. Far from being irrational, crying during joyful moments helps restore balance and deepen human connection.

A new study suggests that forgiving someone does not make us forget what they did—but it does change how we feel about it. People who forgave recalled past wrongs with just as much detail, but with less emotional pain.

A new study suggests that the way people learn to trust others early in life can shape their political ideology and preference for strong, dominant leaders—though not directly, but through dogmatic thinking and broader political attitudes.

Post-orgasmic illness syndrome, a rare condition causing days of fatigue and flu-like symptoms after ejaculation, remains poorly understood. A new review examines the latest research on its causes, mental health effects, and often inconsistent treatment approaches.

A new study suggests that certain gut bacteria may influence the risk of obsessive-compulsive disorder. Using Mendelian randomization, researchers identified specific microbial taxa that appear to protect against or increase OCD symptoms.

Researchers have discovered that frequent cannabis users show reduced spontaneous brain activity in the motor cortex, and this neural suppression is tied to cannabis use severity and response speed, even though overall task performance remained comparable to non-users.
