A massive Danish study of over 1.2 million children has found no evidence that aluminum in early childhood vaccines increases the risk of neurological, autoimmune, or allergic disorders. Researchers analyzed 50 chronic conditions — including autism spectrum disorder (ASD), ADHD, asthma, and juvenile arthritis — and found no association with cumulative aluminum exposure from vaccines […]
Tiny Brain Region Orchestrates How We Segment and Remember Life Events
Our memories don’t flow like a continuous stream—they’re divided into meaningful events, thanks to a tiny brain region called the locus coeruleus. New research shows this region acts like a “reset button,” activating at event boundaries to signal the hippocampus to store distinct memories.
Childhood Emotional Trauma Linked to Later Social Distress
A new study reveals that childhood emotional trauma increases social avoidance and distress in adolescents, but resilience can help mitigate these effects. Surveying 577 junior high students, researchers found resilience acted as a buffer, enabling traumatized teens to engage more positively with peers.
Dogs Can Sniff Out Parkinson’s Disease
Trained detection dogs can identify Parkinson’s disease (PD) with remarkable accuracy by sniffing skin swabs, according to a new study. In double-blind trials, the dogs achieved up to 80% sensitivity and 98% specificity, even when samples came from patients with other health conditions.
Hepatitis C Found in Brain Lining Linked to Schizophrenia, Bipolar Disorder
Researchers have discovered hepatitis C virus (HCV) in the brain lining of individuals with schizophrenia and bipolar disorder, suggesting a possible link between infection and psychiatric symptoms. The study found HCV specifically in the choroid plexus, a structure producing cerebrospinal fluid, but not inside brain tissue itself.
