Children's eating habits and leisure-time patterns may not meet current recommendations as they transition from preschool to school age, according to a study published in the Journal of Nutrition Education and Behavior. Parents of older children reported unhealthy food choices and lower levels of physical activity.
Stanford researchers have discovered a connection between two aging pathways, SIRT6 and NF-kB, which could lead to a new understanding of how cells age. The study found that SIRT6 regulates gene expression by modifying histones, making it harder for NF-kB to trigger the expression of genes associated with aging.
