How Added Sugar Blocks Full Memory Recovery After a Healthy Diet Switch
A meta-analysis of 27 studies finds that switching from junk food to a healthy diet improves memory, but added sugar may permanently limit recovery.
Neuroplex Tracks Nine Brain Circuits Simultaneously in Moving Mice
A new imaging pipeline, Neuroplex, tracks up to nine distinct neuronal populations in real time in freely moving mice, transforming brain-behavior research.
How Brain Diseases Alter Information Sharing: A New fMRI Approach
A new AI method, IID-GCN, decomposes brain scans into redundancy, uniqueness, and synergy, revealing disease-specific patterns beyond traditional connectivity.
Thinking Longer Leads to Worse Decisions
A new study finds that in complex strategic decisions, faster choices are on average of higher quality, challenging the belief that longer deliberation improves outcomes.
How the Alzheimer's Gene APOE4 Shrinks Brain Cells Before Symptoms
A new study in mice reveals that the Alzheimer's risk gene APOE4 increases a protein called Nell2, shrinking neurons and making memory circuits hyperactive early on—changes that predict later memory decline. Reducing Nell2 reversed the effects, suggesting a potential intervention.
Connected Biochip Tracks How Diabetes Triggers Dementia
A new 'organ-on-chip' device links gut, pancreas, and brain to uncover why diabetes raises dementia risk, enabling real-time study of cellular signals.
Nearly Half of Teens Report Harm from Conversational AI
A national study finds that 47.1% of American teens have experienced digital or emotional harm while using conversational AI chatbots, with 13-year-olds most vulnerable.
Brain Region Mapping Reveals Early Alzheimer's Molecular Circuits
Korea Brain Research Institute's new map shows how Alzheimer's molecular changes differ by brain region, offering early clues for targeted interventions.
How the Brain Rewires Itself to Keep You Walking When Vision Fails
A new study reveals the brain's dual strategy for maintaining walking stability when vision is impaired: rigidly activating sensorimotor pathways while boosting connectivity between motor and cognitive control areas.
Vitamin D Linked to 13% Better Cognitive Scores in Older Adults with Sleep and Memory Issues
Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored 13% higher on a cognitive test than those taking none, a new study finds.
Physical Stress Changes Your Voice: Science Behind the Talk Test
New research reveals how physical exertion alters vocal pitch, timing, and stability, with major implications for speech recognition in high-stress settings.
Brain Immune Cells Use Calcium to Drive Anxiety and Compulsive Behavior
New research reveals Hoxb8 microglia use calcium signaling to control anxiety and grooming behaviors, offering a potential target for treating OCD and anxiety disorders.
