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.
