Researchers from the University of Jena, in partnership with researchers from universities in Oita and Hiroshima have demonstrated, by two independent approaches, that even a low concentration of lithium leads to an increased life expectancy in humans as well as in a model organism, the roundworm Caenorhabditis elegans. Lithium is one of many natural nutritional [...]

Aerobic exercise has long been cited as a key to helping seniors maintain health brain function. A study form the University of Illinois at Urbana-Champaign shows that one year of moderate physical exercise can actrually increase the size of the brain’s hippocampus in older adults, leading to an improvement in spatial memory. For the study, [...]

A study published in the American Journal of Clinical Nutrition finds that Omega-3 fats may help the loss of muscle mass from aging. While omega-3’s are known to stimulate protein growth in animals, the effect on human protein metabolism is not known. For eight weeks, 16 healthy, older adults were randomly assigned to receive either [...]

GlobalPost Life expectancy in US is slowing compared with other countriesLos Angeles TimesLife expectancy has risen in the United States over the last 25 years, but it's not rising as fast as it once was. And, compared with other developed nations, US life expectancy doesn't measure up. …Life Expectancy Gains in US Fail to Keep [...]

According to research from the University of Helsinki, Finland, Vitamin E may increase the life expectancy of certain groups of men. The study is published in the Age and Ageing Several large randomized trials of humans found that vitamin E supplementation does not reduce mortality. However, the average effect on mortality in a group of [...]

An estimated 6.5 percent of Americans age 40 and older have the eye disease age-related macular degeneration, a lower rate than was reported 15 years ago, according to a report in the Archives of Ophthalmology. “Despite new medical and surgical interventions, age-related macular degeneration (AMD) remains an important cause of loss of vision in the [...]

Older male mice given water laced with a special concoction of amino acids, they live longer than your average mouse. The study from Italy found that a supplemental mixture of branched-chain amino acids, specifically leucine, isoleucine, and valine, gave the mice the longer life. Whether it works for humans, well that is another study. “This [...]

Like cats, human cells have a finite number of lives. After dividing a certain number of times they change shape, slow their pace, and eventually stop dividing, a phenomenon called “cellular senescence”. Biologists know that a cellular clock composed of structures at the chromosome end known as telomeres records how many “lives” a cell has [...]

Research from Concordia University may have brought the quest for longer life closer. The research is the the first to identify the role of a bile acid, called lithocholic acid (LCA), in extending the lifespan of normally aging yeast. “Our findings imply that LCA extends longevity by targeting two different mechanisms,” says first author Alexander [...]

A two year study from Oxford University has found that certain B vitamins taken in large doses daily can halve the rate of brain shrinkage in elderly people who withr mild memory problems, and may slow their progression toward dementia. The randomised clinical trial is the largest to study to date of the effect of [...]
