William Sharpe was an intriguing figure in the history of American neurosurgery. He was an extraordinarily bright and gifted man who led a flamboyant, colorful, and unconventional life. He had an international impact on the field of neurosurgery during the first half of the 20th century, yet few practicing neurosurgeons know his name. In this report, the authors discuss Sharpe's contributions to neurosurgery along with the remarkable quirkiness that came to define his professional and personal life.

Pennsylvania has over three million rural residents using private water wells for drinking water supplies but is one of the few states that lack statewide water well construction or management standards. The study described in this article aimed to determine the prevalence and causes of common health-based pollutants in water wells and evaluate the need for regulatory management along with voluntary educational programs. Water samples were collected throughout Pennsylvania by Master Well Owner Network volunteers trained by Penn State Extension.

Many people fail to save what they need to for retirement (Munnell, Webb, and Golub-Sass 2009). Research on excessive discounting of the future suggests that removing the lure of immediate rewards by pre-committing to decisions, or elaborating the value of future rewards can both make decisions more future-oriented. In this article, we explore a third and complementary route, one that deals not with present and future rewards, but with present and future selves.

For decades, the hardwood forests of northern Pennsylvania have been subjected to chronic atmospheric loading of acidifying agents. On marginal, high-elevation, unglaciated sites, sugar maples (Acer saccharum Marsh.) have experienced severe decline symptoms and mortality.

Pennsylvania has a large population that relies on private water wells, but no statewide regulations govern the location or construction of the wells. Bacterial contamination occurs in nearly half of these water supplies, representing a health risk to rural residents. The role of large-scale aquifer contamination versus wellhead contamination from poor construction is poorly understood.
