Curing Death by Curing Disease, Cancer & Aging
Taking a calcium supplement of up to 1,000 mg per day can help women live longer, according to a study whose lead author was Lisa Langsetmo, a Ph.D. research associate at McGill University, and whose senior author was professor David Goltzman, Division of Endocrinology and Metabolism in the Department of Medicine of the Faculty of Medicine and researcher in the Musculoskeletal Disorders axis at the Research Institute of the McGill University Health Centre.

 | The first symptoms of major depression may be behavioral, but the common mental illness is based in biology -- and not limited to the brain. In recent years some studies have linked major, long-term depression with life-threatening chronic disease and with earlier death, even after lifestyle risk factors have been taken into account. ...> Full Article |
A study by Stephanie Cosentino, Ph.D., of Columbia University, New York, and colleagues examines the relationship between families with exceptional longevity and cognitive impairment consistent with Alzheimer's disease.

UCLA biologists have identified a gene, previously implicated in Parkinson's disease, that can delay the onset of aging and extend the healthy life span of fruit flies. This research has important potential implications for aging and disease in humans. The gene, Parkin, serves at least two vital functions. By increasing Parkin activity, the scientists extended the lifespan of the flies by more than 25 percent.

Many dog owners have their pets spayed or neutered to help control the pet population, but new research from the University of Georgia suggests the procedure could add to the length of their lives and alter the risk of specific causes of death.

In collaboration with an international research team, University of Copenhagen researchers have for the first time mapped telomerase, an enzyme which has a kind of rejuvenating effect on normal cell aging. The findings have just been published in Nature Genetics and are a step forward in the fight against cancer.

 | New research into aging processes, based on modern genetic techniques, confirms theoretical expectations about the correlation between reproduction and lifespan. Studies of birds reveal that those that have offspring later in life and have fewer broods live longer. And the decisive factor is telomeres, shows research from The University of Gothenburg, Sweden. ...> Full Article |
The answer to longevity may be far simpler than we imagine; it may in fact be right under our noses in the form of a morning caffeine kick. The elderly inhabitants of Ikaria, the Greek island, boast the highest rates of longevity in the World, and many scientists turn to them when looking to discover the 'secrets of a longer life'.

Can the length of strands of DNA in patients with heart disease predict their life expectancy?
Researchers from the Intermountain Heart Institute at Intermountain Medical Center in Salt Lake City, who studied the DNA of more that 3,500 patients with heart disease, say yes it can.

A new study demonstrates what researchers consider conclusive evidence that the red wine compound resveratrol directly activates a protein that promotes health and longevity in animal models. What's more, the researchers have uncovered the molecular mechanism for this interaction, and show that a class of more potent drugs currently in clinical trials act in a similar fashion.

Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why.

 | Nitric oxide, the versatile gas that helps increase blood flow, transmit nerve signals, and regulate immune function, appears to perform one more biological feat -- prolonging the life of an organism and fortifying it against environmental stress, according to a new study. ...> Full Article |
Cognitive decline in old age is linked to decreasing production of new neurons. Scientists from the German Cancer Research Center have discovered in mice that significantly more neurons are generated in the brains of older animals if a signaling molecule called Dickkopf-1 is turned off. In tests for spatial orientation and memory, mice in advanced adult age whose Dickkopf gene had been silenced reached an equal mental performance as young animals.
