Aging may seem unavoidable, but that’s not necessarily so when it comes to the brain. So say researchers in the April 27th issue of the Cell Press journal Trends in Cognitive Sciences explaining that it is what you do in old age that matters more when it comes to maintaining a youthful brain not what you did earlier in life.
Research just published by a team of demographers at the social science research organization NORC at the University of Chicago contradicts a long-held belief that the mortality rate of Americans flattens out above age 80.
One of the big mysteries in biology is why cells age. Now scientists at the Salk Institute for Biological Studies report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.
Drugs that affect the levels of an important brain protein involved in learning and memory reverse cellular changes in the brain seen during aging, according to an animal study in the December 7 issue of The Journal of Neuroscience. The findings could one day aid in the development of new drugs that enhance cognitive function in older adults.
Researchers have identified a potential drug therapy for a premature ageing disease that affects children causing them to age up to eight times as fast as the usual rate.
The study is the first to outline how to limit and repair DNA damage defects in cells and could provide a model for understanding processes that cause us to age.
Regular physical activity is associated with a lower risk of suffering depression in old age. This is shown by one of the largest studies on elderly Europeans to have been carried out, by researchers at the University of Gothenburg, Sweden, among others. Research also shows that self-determined motivation and perceived competence are important factors in persuading elderly people to exercise more.
Health prevention strategies to help Canadians achieve their optimal health potential could add a decade or more of healthy years to the average lifespan and save the economy billions of dollars as a result of reduced cardiovascular disease, says noted cardiologist Dr. Clyde Yancy.
CellÂ’s reserve fighting force shrinks with age, new study finds.
When the body fights oxidative damage, it calls up a reservist enzyme that protects cells Â– but only if those cells are relatively young, a study has found.
Studies from the University of Toronto’s psychology department show that people who use more invasive anti-aging methods such as Botox injections or surgery are viewed more negatively than those who use milder techniques such as sun-avoidance and facial creams and younger adults are more negative about using anti-aging methods than older adults.
Researchers funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered a new mechanism controlling ageing in white blood cells. The research, published in the September issue of the Journal of Immunology, opens up the possibility of temporarily reversing the effects of ageing on immunity and could, in the future, allow for the short-term boosting of the immune systems of older people.
