Summary: A nationally representative, peer-reviewed study finds that nearly half of American adolescents who use conversational artificial intelligence (CAI) chatbots report experiencing digital, emotional, or behavioral harm. The survey collected responses from 3,466 teens aged 13 to 17 and reveals both widespread adoption and concerning exposure to unsafe content, privacy intrusions, manipulation, and prompts toward … Read more

Summary: A multinational clinical trial found that a new antibody, NG101, preserves existing nerve tissue and speeds regression of spinal cord lesions after acute injury. NG101 works by neutralizing Nogo-A, a naturally occurring protein that inhibits nerve fiber regrowth. Using advanced magnetic resonance imaging (MRI) together with clinical assessments, researchers were able to visualize how … Read more

Summary: New collaborative research indicates that preserving strong overall brain health can shield memory and thinking abilities from the earliest damaging effects of Alzheimer’s disease. Researchers explored why some older adults remain cognitively sharp even though their brains show early Alzheimer’s-related biological changes. The study identifies structural brain integrity and life-course advantages as important buffers … Read more

Summary: Engineers and physicians have created a miniature, wireless polygraph-like system that adheres to the chest like a soft, lightweight bandage. Rather than focusing on detecting lies, the device continuously captures hidden physiological stress signals from the body without requiring access to chemical biomarkers in bodily fluids. By streaming synchronized, real-time measurements of heart activity, … Read more

Summary: New analysis reframes spinal cord injury (SCI) from a localized motor-pathway disruption into a systems-level disorder. The authors argue that SCI severs communication, desynchronizes physiological states, and prevents the learning processes that support adaptive movement across the brain–body–environment loop. True, lasting recovery demands more than isolated muscle activation. Rehabilitation must rebuild a continuous, closed-loop … Read more

Summary: A new evolutionary study offers a clear and testable explanation for one of anthropology’s longest-standing puzzles: why about 90% of people worldwide favour their right hand. This population-level bias is unique among primates, and the research shows it follows logically from two key human traits—bipedalism and dramatic brain expansion. Key Facts The evolutionary trajectory: … Read more

Summary: A new study reveals the first complete neural blueprint explaining how fruit flies (Drosophila melanogaster) execute ultra-fast escape behaviors. By mining a high-resolution electron microscopy connectome of the fly’s ventral nerve cord—the insect equivalent of a spinal cord—researchers mapped all 1,314 descending neurons and identified rare axo-axonic synapses that modulate and synchronize motor commands … Read more

Summary: Researchers have identified the core mechanism driving IgLON5 encephalitis (Anti-IgLON5 disease). Using antibodies taken from affected patients and applied to neuronal cell cultures and mice, the team demonstrated a direct causal link between autoimmune attacks on the cell-surface protein IgLON5 and the toxic aggregation of intracellular Tau proteins. This discovery reveals that abnormal neuronal … Read more

Summary: A multinational phase 2b clinical trial found that NG101, a novel recombinant antibody, preserves existing nerve tissue and accelerates the regression of spinal cord lesions after acute cervical injury by neutralizing the inhibitory protein Nogo-A. High-resolution MRI combined with clinical measures allowed researchers to visualize treatment-related structural changes early in the recovery process, offering … Read more

Summary: A Phase 2 randomized clinical trial from the Karolinska Institute found that a single 25 mg dose of psilocybin, combined with structured psychotherapeutic support, produced a rapid, statistically significant, and clinically meaningful reduction in symptoms among people with recurrent major depression. The antidepressant effect was detectable as early as day two by self-report, and … Read more
