Everyday Skills Shield the Brain from Prenatal Stress, Study Finds
Children with strong adaptive skills—like communication and self-care—show healthy brain activity even after prenatal stress, a new study using Superstorm Sandy as a natural experiment reveals.
How Simple Images Boost Brain-Like AI Alignment: New Study
New research shows that images with fewer interpretations align vision and language AI models better, hinting at how our brains unify senses.
Why Mimicking AI Reasoning Fails: The Cognitive Cost of Superficial Imitation
New research shows that teaching AI by imitating reasoning traces destroys the natural alignment with human cognitive costs, revealing that true understanding requires active learning.
Alzheimer's Inflammation Trigger: STING Protein SNO Modification
Researchers found a molecular switch on the STING protein that drives chronic brain inflammation in Alzheimer's. Blocking it reduced synapse loss in mice.
Baby Teeth Reveal Critical Windows for Metal Exposure & Brain Health
A decade-long study used baby teeth to pinpoint two early-life windows where metal exposure most impacts brain connectivity and behavioral health in adolescence.
SuperAgers in Their 80s Have Memories of 50-Year-Olds: What Scientists Found
Northwestern University researchers reveal how a rare group of 80+ SuperAgers retain memory comparable to people 30 years younger, through brain resistance or resilience to Alzheimer's damage.
Dopamine Loss Drives Alzheimer's Memory Failure — And a Common Drug May Restore It
New research shows dopamine levels in a key memory region drop by over 80% in Alzheimer's, and using the Parkinson's drug Levodopa restored memory in mice.
Stroke Severity Directly Linked to Dementia Risk: 30-Year Study
A 30-year study of 42,000 adults reveals a dose-response relationship: the more severe the stroke, the higher the dementia risk, with severe strokes quintupling the odds.
GLP-1 Drugs Like Semaglutide Show Promise Against Alzheimer's Roots
A review of 30 studies finds that GLP-1 receptor agonists reduce amyloid-beta and tau buildup, targeting Alzheimer's biological drivers.
ADHD Traits Found in 25% of Chronic Pain Patients: Hidden Link
A study of nearly 1,000 patients reveals that 25% of chronic pain sufferers exhibit ADHD traits, which amplify pain through anxiety and depression.
White Matter Damage Triggers Repair and Disease Cycles
New research shows that localized white matter damage causes remote grey matter loss, but regenerating myelin can reverse the damage, offering a new target for neurodegenerative disease treatments.
Astrocytes Build Their Own Long-Range Brain Networks, Study Finds
Astrocytes, long thought to be mere support cells, form their own brain-wide signaling networks, challenging 100 years of neuron-centric theory.
