Science-backed news on intelligence, neuroscience, and brain training
Brain's Waste-Clearing System Has Fast and Slow Lanes
AI reveals fluid moves 50x faster around the brain than through deep tissue, offering new clues for detecting Alzheimer's and concussions.
Immune cells from blood enter aging brain, Stanford study finds
Stanford researchers discovered that immune cells from the blood enter the aging brain and become microglia, overturning long-held assumptions about the brain's isolation from the body's immune system.
Brain Activity Drives Alzheimer's Spread: New Model
A new model shows that neuronal activity influences how Alzheimer's pathology spreads through the brain, predicting progression and suggesting activity-modulating therapies.
Can Brain Stimulation Boost Working Memory? New Meta-Analysis Weighs In
A new meta-analysis finds that combining transcranial direct current stimulation with cognitive training may enhance working memory in healthy adults, but effects are modest and task-specific.
Metacognition Is a Skill You Can Train: New Theory
A new computational theory proposes that metacognitive abilities—like self-monitoring and control—are learned skills, developed through practice-driven automation.
How a Hierarchical Energy-Based Model Explains Multimodal Cognition
New model IM-LEPP integrates vision and language in a hierarchical energy-based framework, explaining attention, language processing, and memory.
Comparing Memory in Brains and LLMs: A New Research Opportunity
Researchers compare memory in brains and large language models to propose that LLMs offer stronger experimental access, potentially sharpening biological hypotheses about memory.
EyeBrain: Pupil Diameter & Fixation Duration Reveal Brain Hemisphere Activity
New research shows pupil diameter and fixation duration can classify left vs. right brain activity with 89.4% accuracy, offering a non-invasive window into cognitive states.
How Integrative Models Unify Brain, Body, and Behavior
New research argues for integrative neurocybernetic models that unify brain, body, and behavior, potentially revolutionizing our understanding of cognition.
AI Chatbots Engineered for Addiction, New Research Reveals
New research reveals AI chatbots are designed to be addictive, using dark patterns like guilt-tripping deletion prompts and instant validation to keep users hooked.
Estrogen Therapy Linked to Fewer Alzheimer's Signs in Brain
New research links estrogen-only menopause therapy to fewer Alzheimer's brain markers at autopsy, but it's not proof of prevention.
How Sleep and Age Shape Your Brain's Awake Signals
New research shows that your brain waves while awake reflect your sleep debt, and children and adults respond to sleep differently, revealing a puberty shift.
