Alzheimer's disease study links brain health, physical activity

People at risk for Alzheimer’s disease who do more moderate-intensity physical activity, but not light-intensity physical activity, are more likely to have healthy patterns of glucose metabolism in their brain, according to a new UW-Madison study. Results of the research were published online in Journal of Alzheimer’s Disease. Senior author Dr. Ozioma Okonkwo, assistant professor of medicine, is a researcher ...

19-year-olds as sedentary as 60-year-olds, study suggests

Physical activity among children and teens is lower than previously thought, and, in another surprise finding, young adults after the age of 20 show the only increases in activity over the lifespan, suggests a study conducted by researchers from the Johns Hopkins Bloomberg School of Public Health. And, the study found, starting at age 35, activity levels declined through midlife ...

The road not taken: Do stress-specific mutations lead down different evolutionary paths?

Starvation for essential elements determines the pattern of genetic variation. Evolution is rather simple in outline; plentiful biological variation allows natural selection to pick the fittest variant that reproduces and out-competes the other variants in a population. Since Darwin, we have learned a lot about how selection and fitness determine evolutionary outcomes but a lot less about the variation part ...
