  "textContent": "As the body ages, cells naturally accumulate dozens of genetic mutations each year. New research from Boston Children's Hospital, published in Cell, finds that the brain's resident immune cells, microglia, amass mutations in specific cancer-driving genes, yet they don't manifest as cancer. Instead, these mutations may help drive Alzheimer's disease.",
