Science-backed news on intelligence, neuroscience, and brain training
Machine Intelligence Is Only Partially Interpretable, Study Finds
A large-scale factor analysis of 13,251 evaluation scores from 1,618 language models finds that a general intelligence factor explains at most 70.8% of performance variance, challenging the idea of a single domain-free AI ability.
Midlife Movement May Shield Your Brain Decades Later
A UT Health San Antonio study of 402 adults finds midlife physical activity and healthy blood sugar may slow cognitive decline years later — with benefits varying by ethnicity.
Neck Surgery May Drain Brain's Waste System, Study Finds
A Neuron study links cervical lymph node removal during neck cancer surgery to blocked cerebrospinal fluid drainage, brain atrophy, and higher-than-expected cognitive impairment rates.
AI Models Show Stroop-Like Conflict, Rivaling Human Brain
Large language models show congruency effects like humans in a verbal conflict task, revealing competition between default habits and rule-based control.
Alzheimer's Immune Trigger Found Outside the Brain in Lymph Nodes
WashU Medicine scientists found that T cells driving Alzheimer's brain damage get activated in lymph nodes first. Blocking that signal preserved cognition in mice.
Brain-Inspired AI Trick Stops 'Stability Gap' Learning Drop
Researchers borrowed a trick from noradrenaline in the brain to help AI keep old skills while learning new ones — without the usual dip in performance.
Exercise May Help the Aging Brain Clear Harmful Waste
A new review from Victoria University finds exercise may boost the brain's glymphatic cleanup system through better sleep, lower inflammation, and healthier blood vessels.
Your Breath Sets Your Reaction Speed, Study Finds
Northwestern researchers found people react 41 milliseconds faster while exhaling than inhaling, linking the rhythm of breathing directly to motor speed.
AI Learns Brain Equations From Chaotic Data, Even With Extreme Noise
A new machine learning method called PEM-UDE recovers the hidden equations behind chaotic systems — even when noise is five times the signal — and extracts brain network rules from neuron data.
7-Day Meditation Retreat Changed Brains and Blood, Study Finds
A UC San Diego study found that a 7-day intensive meditation retreat produced measurable changes in brain connectivity, neuroplasticity, immunity, metabolism, and natural pain relief.
Glucosamine Linked to 25% Faster MCI-to-Dementia Progression
A University of Florida analysis of 2012–2024 health records found glucosamine use tied to a 25% higher likelihood that mild cognitive impairment progresses to dementia.
Nearly Half of Dementia Cases Linked to Risks You Can Change
A four-year Lund University brain study found smoking, high blood pressure, heart disease, and high blood lipids were strongly tied to vascular brain damage, suggesting healthier habits could help delay dementia.
