Maternal Estrogen at 6-8 Weeks Predicts Newborn IQ-Related Head Size
Maternal estrogen levels at 6-8 weeks gestation directly predict newborn head circumference, a marker for brain size and future IQ, with stronger effects in males.
Shunting Inhibition Helps Dendrites Assign Credit in Local Learning
New study shows how shunting inhibition and dendritic branching reshape credit-signal geometry, improving local learning with restricted feedback.
BCG Vaccine Flushes Alzheimer's Amyloid: Early Prevention Pathway
The BCG vaccine remodels brain immunity, lowering Alzheimer's amyloid in healthy adults. A study finds it clears toxic protein into the blood, offering early prevention.
Tire Pollutant 6PPD-Q Linked to Alzheimer's Gene Pathways
A computational study reveals that tire-derived pollutant 6PPD-quinone binds to three key Alzheimer's predictor genes, triggering oxidative stress and neuroinflammation.
Mediterranean Diet Boosts Psychological Well-Being After 50, Study Finds
New research shows that sticking to a Mediterranean diet significantly improves autonomy, purpose, and self-realization in adults over 50, acting as a buffer against emotional decline during the pandemic.
New Soft Exoskeleton Glove Restores Grasp in Paralysis Using Faint Muscle Signals
A low-cost pneumatic glove reads weak forearm muscle signals with 97% accuracy, enabling an ALS patient to hold a fork for the first time in four years.
How Damaged Myelin Disrupts Sleep Rhythms and Brain Health
Myelin damage triggers abnormal, epilepsy-like spikes during NREM sleep and slows REM oscillations, suggesting sleep recordings could track MS and Alzheimer's progression.
Newly Discovered Brain Cell Death Mechanism May Explain Alzheimer's Neuron Loss
Researchers at King's College London have identified a previously unknown process called karyoptosis that may explain how toxic proteins kill brain cells in Alzheimer's and frontotemporal dementia.
Stress Drinking in Youth Permanently Rewires Brain, Study Finds
New research from UMass Amherst shows that using alcohol to cope with stress in early adulthood can permanently alter brain circuits, reducing mental flexibility and increasing dementia risk even after years of sobriety.
Deep Sleep Circuit Links Growth Hormone to Muscle Repair and Brain Health
UC Berkeley scientists discovered the brain circuit that controls growth hormone release during deep sleep, revealing a feedback loop that regulates muscle repair, fat metabolism, and cognition.
Zebrafish brains use the same sensory sorting logic as humans, study finds
New research shows larval zebrafish organize sensory signals using a spatial ladder identical to the human thalamocortical network, proving multisensory integration follows universal evolutionary rules.
New Drug XL20 Protects Neurons in ALS by Targeting Toxic Protein Region
Researchers at the University of Arizona developed XL20, a small molecule that crosses the blood-brain barrier to block a toxic region of the TDP-43 protein, halting neuron death and slowing muscle wasting in ALS models.
