    Studysummary In this study, researchers developed a simple, non-invasive method to monitor circadian gene expression using whole hair root cultures, finding that elderly dementia patients' peripheral clocks still oscillate similarly to younger, healthier individuals, which suggests cellular senescence minimally affects some aspects of circadian rhythms.
