New method detects Alzheimer's early using AI brain scans

Scientists have developed an innovative AI-based imaging technique that identifies Alzheimer's disease up to a decade before symptoms emerge. The approach analyzes subtle changes in brain structure from routine MRI scans. This breakthrough, published on October 2, 2025, could transform early intervention strategies.

Evolution of human intelligence linked to mental illness vulnerability

Researchers have traced genetic variants in the human genome to reveal that advances in cognitive abilities around 500,000 years ago were soon followed by mutations increasing susceptibility to psychiatric disorders. This suggests a trade-off in brain evolution. The study, published in Cerebral Cortex, analyzed 33,000 genetic variants to build an evolutionary timeline of brain-related traits.

Playing musical instruments boosts children's reading skills

A new study reveals that children who learn to play musical instruments show significant improvements in reading abilities. The research highlights how musical training enhances phonological awareness, a key component of literacy development. These findings suggest potential benefits for integrating music education in schools.

New study reveals key mechanism in Alzheimer's disease

Scientists have identified a novel molecular pathway that contributes to the progression of Alzheimer's disease, potentially opening doors to new treatments. The research, published in a leading journal, highlights how specific proteins interact to accelerate brain cell damage. This discovery builds on years of investigation into neurodegenerative disorders.

Harvard study links gut bacteria to lower anxiety levels

Researchers at Harvard University have identified specific gut microbiome compositions associated with reduced anxiety in humans. The two-year study, published today, strengthens evidence for the gut-brain connection. This discovery opens doors to microbiome-based mental health interventions.

Scientists uncover brain circuit that overrides chronic pain

Researchers at the University of Pennsylvania have identified a group of brainstem neurons that can suppress chronic pain signals when survival needs like hunger or fear arise. These Y1 receptor neurons in the lateral parabrachial nucleus act as a neural switchboard, prioritizing urgent biological demands over persistent discomfort. The discovery, published in Nature, offers potential new avenues for pain treatments.

Researchers identify gut bacterium linked to brain health
