Is aging inevitable? What factors make older tissues in the human body less able to maintain and repair themselves, as in the weakening and shrinkage of aging muscles in humans? A new study from Massachusetts General Hospital (MGH) investigators and collaborators at King's College London describes the mechanism behind impaired muscle repair during aging and a strategy that may help rejuvenate aging tissue by manipulating the environment in which muscle stem cells reside. The report will appear in the journal Nature and has received advance online release.

A new report released today, Active Design Supplement: Promoting Safety, by the Johns Hopkins Center for Injury Research and Policy, New York City Department of Health & Mental Hygiene's Built Environment and Healthy Housing Program, and the Society for Public Health Education (SOPHE) provides explicit guidelines for urban planners, architects, public health advocates, and others to consider when promoting active designs.

WASHINGTON — The aging of the U.S. population will have broad economic consequences for the country, particularly for federal programs that support the elderly, and its long-term effects on all generations will be mediated by how -- and how quickly -- the nation responds, says a new congressionally mandated report from the National Research Council.

According to a new study co-authored by Simon Fraser University economics professor Steeve Mongrain, parole board decisions can have a huge impact on whether or not prisoners are motivated to rehabilitate.
