Regular exercise is associated with a delay in the onset of dementia and Alzheimers disease, according to a Group Health Cooperative/University of Washington study that will appear in the January 17 issue of Annals of Internal Medicine. The study--the most definitive investigation of exercise and dementia to date--also found that the more frail a person is, the more he or she may benefit from exercise.
"Even those elderly people who did modest amounts of gentle exercise, such as walking for 15 minutes three times a week, appeared to benefit," says Eric B. Larson, director of Group Health Cooperatives Center for Health Studies and the lead investigator for the study.
"Based on these findings, we can advise older people to use it even after you start to lose it, because exercise may slow the progression of age-related problems in thinking," said Larson.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
