Can we blame early menopause in women on lack of exercise? How can sleep deprivation trigger and consuming whole grains potentially prevent Type 2 diabetes? How can marriage prevent malnutrition in the elderly? Can exercise trigger production of new neurons and improve cognition in Alzheimer's? Find answers to these questions and more in this week's edition of Science Weekly.

How weight loss is linked to future health for older adults
A study evaluated information from the Study of Osteoporotic Fractures and looked specifically at health and weight for women who were over age 65. Reviewing more than 20 years' worth of data for study participants, the team of researchers had the chance to examine links between long-term weight gain/loss and health.

Losing just six hours of sleep could increase diabetes risk, study finds
Losing a single night's sleep may affect the liver's ability to produce glucose and process insulin, increasing the risk of metabolic diseases such as hepatic steatosis (fatty liver) and type 2 diabetes.

How exercise generates new neurons, improves cognition in Alzheimer's mouse
A study finds that neurogenesis -- inducing the production of new neurons -- in the brain structure in which memories are encoded can improve cognitive function in a mouse model of Alzheimer's disease.

Obesity: We inherit the dangerous fat from Dad -- and the good fat from Mom
Brown fat cells burn off a lot of calories, whereas an excess of white fat cells make us overweight and ill. Now researchers have identified a new gene in brown fat cells; a gene that may be crucial for the future's treatment of obesity.
