Chronological age does not fully capture the substantial interindividual variability in aging, prompting growing interest in biomarkers that reflect biological aging and susceptibility to age-related disease. Clonal hematopoiesis of indeterminate potential (CHIP), characterized by the age-related expansion of hematopoietic clones carrying somatic mutations in the absence of an overt hematologic malignancy, has emerged as a potential link between somatic evolution, chronic inflammation, and age-related disease. This narrative review examines the biological mechanisms linking clonal hematopoiesis to aging, evaluates the evidence supporting CHIP as an emerging biomarker of biological aging, and discusses its potential implications and current limitations in longevity medicine. CHIP becomes increasingly prevalent with age and reflects the interplay between somatic mutation accumulation, clonal selection, and an aging inflammatory microenvironment. Growing evidence links CHIP to epigenetic age acceleration, with associations influenced by the mutated gene, clone size, and clonal architecture. Beyond its established risk of progression to myeloid malignancy, CHIP is associated with cardi

Scientists have discovered an unexpected reason why Alzheimer's disease disrupts sleep, and their findings suggest that the problem may be reversible. In experiments involving mice with Alzheimer's-like brain changes, researchers restored more than two hours of sleep per day without removing the amyloid plaques associated with the disease. The surprising discovery points to an overlooked culprit: the brain's own immune cells. Rather than simply protecting the brain from damage, these cells can trigger inflammation that interferes with healthy sleep.
