Mothers experience major metabolic adaptations during pregnancy and lactation to support the development and growth of the new life. Although many metabolic changes have been studied, body temperature regulation and environmental temperature preference during and after pregnancy remain poorly understood. Researchers at Baylor College of Medicine and collaborating institutions show that postpartum female mice develop new environmental temperature preferences and reveal brain changes mediating these changes.

For human health, prematurely aging cells are a big problem. When a cell ages and stops growing, its function changes, which can cause or worsen cardiovascular disease, Alzheimer’s disease and other chronic diseases. But these cells are also like needles in a haystack, difficult to identify by traditional scientific measures.
