Study supports physical activity programs for preventing disability among elderly patients
Arthritis is the leading cause of disability in the United States. Nearly 60 percent of Americans ages 65 and older suffer with some form of this progressive joint disease. For more than 1 in 10 sufferers, arthritis makes simple, everyday tasks, from walking up a flight of stairs to bathing and dressing, extremely difficult. By 2010, arthritis is projected to affect almost 40 million Americans over age 65, potentially increasing the ranks of senior citizens with disabilities that can limit independent living.
To avert an epidemic of disability in the future and ease the burden on Medicare, researchers are seeking to understand better and manage all the components – demographic, biological, socioeconomic, and behavioral – that contribute to functional decline in arthritis patients. Toward this goal, a team of researchers at Northwestern University conducted a long-term study of various risk factors, based on a large national sample of older adults with arthritis. Their findings, featured in the April 2005 issue of Arthritis & Rheumatism, offer good news for guiding effective prevention efforts. Among the subjects – 5,715 women and men ages 65 and up – the strongest predictor of the loss of ability to perform basic activities of daily living after developing arthritis was the lack of regular vigorous physical activity.

Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications.
Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one. They are found at the...
Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
