A new study published in Social Cognitive and Affective Neuroscience (Open Access) examined how adults with different levels of depressive symptoms evaluate statements about themselves. Using fMRI, researchers found that depression is linked to slower decision-making, greater ambivalence, and altered activity in brain regions responsible for self-reflection. The findings shed light on why self-beliefs often feel unclear, rigid, or conflicted in depression, suggesting that the underlying neural processes of self-evaluation shift with symptom severity.
A new Open Access study in Journal of Cybersecurity provides one of the most detailed multinational assessments of image-based sexual abuse (IBSA) perpetration to date. Surveying more than 16,000 adults across 10 countries, researchers found that over one in ten respondents reported creating, taking, sharing, or threatening to share intimate images without consent. The findings show how digital platforms, communication tools, and cultural norms shape these behaviors, revealing widespread exposure, diverse motivations, and significant gaps in current prevention strategies.
A new Open Access study in Cerebral Cortex uses advanced brain-imaging methods to examine how white matter pathways develop in autistic children and young adults. Analyzing 365 participants, the researchers mapped microstructural differences along the brain's major communication routes and found that autism involves localized changes in both interhemispheric and within-hemisphere pathways. By identifying the exact portions of tracts that differ, the study offers a clearer picture of how sensory, language, and emotional processes may develop differently across individuals.
A new narrative review published in Nutrition Reviews analyzes the growing evidence on berberine, a plant-derived alkaloid widely used in traditional medicine and increasingly studied for its metabolic and therapeutic properties. The authors examine berberine's chemical characteristics, absorption, metabolism, and diverse biological actions - ranging from antimicrobial and anti-inflammatory effects to potential benefits for diabetes, obesity, and cardiovascular health. The review emphasizes that while berberine shows measurable clinical promise, its effects are not universally applicable and require cautious interpretation.
A large international survey published in Aesthetic Surgery Journal Open Forum explored how adults aged 50 to 80 perceive aging, self-confidence, and the role of aesthetic treatments. The study, which included over 7,500 participants across eight countries, found that most older adults report strong satisfaction with their mental well-being and view aesthetic medicine as emotionally beneficial, even among those who never sought treatment. These results challenge stereotypes about aging, showing that confidence and self-image remain dynamic well into later life.
A new open-access paper in the Journal of Language Evolution proposes a unified framework to test theories about how human language first emerged. Researchers from Cardiff University and collaborating institutions combined causal inference with experimental semiotics to model early communication through shared survival tasks. By recreating ancient cooperative scenarios - such as building shelters and maintaining fires - they found that symbolic language arises only under specific pressures, like information asymmetry and distance between communicators. The work establishes a testable foundation for studying language evolution.
A study in SLEEP Advances reveals that specific patterns of alpha brain waves detected during rest may serve as early indicators of cognitive decline in patients with idiopathic REM sleep behavior disorder (iRBD). Researchers from Seoul National University and international collaborators found that higher, spatially clustered alpha activity correlated with lower cognitive scores, even after adjusting for age, sex, mood, and medication. The findings highlight the potential of resting-state EEG as a noninvasive biomarker for neurodegenerative risk.
A new study published in Clinical Chemistry challenges the scientific basis of current per se and zero-tolerance laws for cannabis-related driving impairment. Researchers found that many regular cannabis users still exceeded legal THC blood thresholds several days after their last use, despite showing no signs of diminished driving performance. The findings raise questions about how impairment is defined and whether existing laws accurately reflect biological and behavioral realities surrounding cannabis use.
Weight management is one of the toughest challenges for people living with psychiatric conditions. Many mood-stabilizing and antipsychotic medications cause weight gain and metabolic imbalance, increasing the risk of diabetes and cardiovascular disease. A new meta-analysis in the Journal of the Endocrine Society shows that GLP-1 receptor agonists - drugs such as semaglutide and liraglutide - can safely reverse this trend. Across ten clinical trials, patients with schizophrenia, bipolar disorder, depression, and binge-eating disorder lost about five kilograms and improved glucose control, while side effects were mild and temporary. Beyond their metabolic effects, GLP-1 drugs appear to influence brain pathways tied to appetite and reward, hinting at a deeper connection between emotional stability and physiological balance.
