Summary: New research from the University of Surrey shows that a safe, non-invasive form of brain stimulation can enhance mathematical learning in young adults who have lower natural connectivity between key brain regions. Participants who received high-frequency transcranial random noise stimulation (tRNS) to the dorsolateral prefrontal cortex (dlPFC) improved more during a five-day maths training … Read more

Summary: Researchers have created a new tool that estimates an individual’s rate of aging from a single brain MRI. This brain-derived aging metric predicts future risk of chronic diseases and dementia years before symptoms appear. Unlike many prior “aging clocks,” the model was trained on longitudinal data from the same people across decades, reducing generational … Read more

Summary: A new study finds a link between lactose intolerance, other food sensitivities, and disturbed sleep, including more frequent and vivid nightmares. In a survey of more than 1,000 university students, those reporting dairy intolerance also reported greater gastrointestinal distress at night and more disturbing dreams, suggesting a connection between nighttime physical discomfort and dream … Read more

Summary: Diagnosing PTSD in children is challenging when communication or emotional awareness is limited. New research from the University of South Florida uses privacy-preserving artificial intelligence to detect PTSD-related facial expression patterns during interviews, offering an objective tool to support clinicians. The system avoids using raw video. Instead, it analyzes de-identified facial signals such as … Read more

Summary: New research demonstrates that low-intensity repetitive transcranial magnetic stimulation (rTMS) can restore important synaptic structures in a mouse model of Alzheimer’s disease (AD). The study reveals that axonal boutons—specialized presynaptic endings where neurons connect—show reduced turnover in AD mice, reflecting impaired synaptic plasticity. A single low-intensity rTMS session selectively increased turnover of one bouton … Read more

Summary: A comprehensive review of more than a century of research calls into question the long-held belief that left-handed people are inherently more creative. After examining nearly 1,000 studies, researchers found no consistent creative advantage for left-handers; in some standardized tests and in many professions, right-handers performed as well as or slightly better than left-handers. … Read more

Summary: New research from NYU Abu Dhabi explains how a tiny chemical modification on messenger RNA — known as m6A methylation — helps organize the developing brain. The study shows m6A controls the production of proteins required for axon growth, notably APC and β-actin, and that disrupting this mechanism can affect neural circuit formation and … Read more

Summary: New research maps how the brain navigates emotional shifts by using music to evoke and measure changing neural patterns. The study shows that responses to a given emotion are strongly shaped by the emotional state that immediately preceded it, a finding with potential relevance for understanding and treating emotional inflexibility in mood disorders. For … Read more

Summary: New research shows people view empathic messages as more supportive and emotionally satisfying when they believe those messages come from another person — even when the messages are identical and generated by artificial intelligence. Across nine experiments with more than 6,000 participants, messages labeled as human were consistently judged as more genuine, especially when … Read more

Summary: New research finds that complete songs are far more effective than spoken-word lyrics at triggering personal memories. By comparing listeners’ responses to popular pop song excerpts and to the same lyrics read aloud, investigators show that musical recordings anchor memories to specific times and emotions, producing quicker recall and stronger feelings of re-living past … Read more
