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.

Stanford researchers have created a CRISPR-based technology to target RNA in neurons, enabling repair processes for genetic diseases. The method addresses key challenges in Cas9 delivery and DNA repair. It reveals unique genome editing rules in neurons, paving the way for targeted therapies.

Brain's superior colliculus rotates to focus on sounds

Researchers have discovered that a part of the brain physically swivels to help focus on sounds coming from different directions. This finding, based on experiments in mice, reveals a new mechanism for auditory attention similar to how eyes move for vision. The study was led by scientists at University College London and published in Nature.

Glioblastoma erodes skull and disrupts immune system, study reveals

Researchers have discovered that glioblastoma, the most aggressive form of brain cancer, extends beyond the brain by eroding the skull and altering the immune cells in skull marrow. This interaction fuels the cancer's progression and explains why current treatments often fail. The findings, published in Nature Neuroscience, suggest new strategies targeting both brain and bone.

Study identifies potential genetic subtypes of autism

Researchers have proposed that autism spectrum disorder may consist of genetically distinct subtypes, based on an analysis of large-scale genetic data. This finding could lead to more personalized approaches to diagnosis and treatment. The study highlights variations in genetic markers among individuals with autism.

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.

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

A new study uncovers a specific gut bacterium that produces a molecule capable of influencing brain function in mice. Led by scientists at the University of California, Berkeley, the research highlights potential new avenues for treating neurological disorders. The findings were published on September 29, 2025, in the journal Nature.
