Adolescents embody the best hopes of American society. Their vital role in shaping our future lends particular significance to their success in negotiating the passage from childhood to adulthood, while their intensity and visibility often make them barometers of social change. It is all the more remarkable, then, that this critical period has only recently captured the full attention of researchers.

"At the Threshold" presents the long-awaited findings of the Carnegie Foundation study on adolescence. It offers a comprehensive overview of what investigators are learning about normal development and provides an interdisciplinary synthesis of research into the biological, social, and psychological changes occurring during this key stage in the life span. While focusing on the contexts of adolescent life - social and ethnic, family and school, leisure and work-it also addresses how researchers are doing in the effort to understand the intersection of processes that initiate and sustain adolescent development and to characterize the extraordinary changes that occur during these years.

Contrary to popular belief, large numbers of young people continue to mature into productive members of society. "At the Threshold" seeks to allow professionals and nonprofessionals alike important access to the reality of normal adolescent experience. The authors recognize that only if we begin to understand and clearly articulate the parameters of successful adolescent development can we hope to intervene with those individuals whose lives seem aimed toward unsatisfactory futures.

The University of Florida has an ambitious goal: to harness the power of its faculty, staff, students, and alumni to solve some of society's most pressing problems and to become a resource for the state of Florida, the nation, and the world. In the upcoming decades, an unprecedented demographic shift will take place; the eighty-five and over population is projected to climb far higher than any other age group. To keep the current elderly population healthy and help prevent future generations from experiencing poor health outcomes, researchers are studying crucial connections between skeletal muscles and whole-body health. The University of Florida is at the forefront of this research, utilizing its nationally recognized excellence in the fields of muscle biology and exercise physiology to discover unique ways to preserve muscle health in the aging and those with diseases. Find out how the proteins within muscle can be manipulated to reduce recovery times for individuals who are bedridden. Learn how older, elite athletes have resisted the inevitable degeneration that comes with aging, and how intermittent fasting may help you live longer and healthier. Step inside the lab where a researcher is uncovering the origins of cancer cachexia a wasting syndrome responsible for 20 percent of cancer deaths worldwide to improve the lives of patients. The loss of skeletal muscle through disease, disuse, or aging is associated with a host of poor health outcomes, but promising new avenues of research are being studied every day at the University of Florida to make for a healthier tomorrow.
