Mobile phone navigation service for older people gets them there step by step Scientists have developed a mobile phone-based navigation service which guides older users to the right address, even when lost in a strange town. The service helps older people to use public transport, assisting them along the entire route. This intuitive navigation service differs from standard public transport applications by offering continuous guidance during the journey, walking directions to stops and destinations, and timetable and real-time information. It helps senior travelers to find the right mode of transport, change routes, get off at the right stop and walk to the destination from the last stop.
Bioethicist calls on researchers for more evidence-based end-of-life care programs Although the public and private sectors are currently engaged in an unprecedented array of efforts to improve end-of-life care, too many of these programs are not evidence-based, says one expert. Investigators and research sponsors must be more involved to 'identify, develop and rigorously test interventions so they can offer guidance' on implementing programs that work among the terminally ill.
What metabolism could reveal about aging and mortality Why some people live much longer than others is an enduring mystery. Now, based on a study of a worm, scientists are getting one step closer to understanding longevity. They report that the metabolic profiles of the worms could accurately predict how long they would live and that middle age could be a key turning point.
Tracking down the secret of aging Researchers have found differences between normal and pathologic peptidomic changes that may lead to an improved understanding of molecular mechanisms underlying aging. Proteome analysis in combination with therapy may influence pathologic aging.
