Herbal extract found to increase lifespan
The herbal extract of a yellow-flowered mountain plant indigenous to the Arctic regions of Europe and Asia increased the lifespan of fruit fly populations, according to a University of California, Irvine study view more (2007-12-06)
Could mice hold the secret to longer life?
Scientists from the University of Aberdeen, the Aberdeen-based Rowett Research Institute and the Medical Research Council (MRC) in Cambridge have made a major breakthrough in understanding how metabolism affects lifespan. In a seven-year study of mice they found that those with the highest metabolic rate lived the longest, raising the prospect... view more... (2004-05-28)
MIT links gene to cholesterol
MIT researchers have discovered a link between a gene believed to promote long lifespan and a pathway that flushes cholesterol from the body. view more (2007-10-12)
Activating protein enhances average lifespan, limits age-related disease in mice
Metabolism researchers at Washington University School of Medicine in St. Louis have found that although it does not extend maximum lifespan in mice, activating a protein in muscle tissue increases average lifespan and prevents some age-related diseases. view more (2007-12-05)
Sexual reproduction delays aging in a mammalian species
Past research on aging and the life histories of diverse species has shown that sexual reproduction is biologically costly for individuals and tends to decrease lifespan rather than increase it. view more (2006-02-22)
Forget the antioxidants? McGill researchers cast doubt on role of free radicals in aging
For more than 40 years, the prevailing explanation of why we get old has been tied to what is called oxidative stress. This theory postulates that when molecules like free radicals, oxygen ions and peroxides build up in cells, they overwhelm the cells' ability to repair the damage they cause, and the cells age. view more (2009-02-18)
Role for CISD2 gene in human disease and lifespan control
In the May 15th issue of G&D, Dr. Ting-Fen Tsai (The National Yang-Ming University, Taiwan) and colleagues present a new animal model of human Wolfram Syndrome, and effectively link CISD2 gene function, mitochondrial integrity and aging in mammals. view more (2009-05-15)
Naturally produced estrogen may protect women from Parkinson's disease
Women who have more years of fertility (the time from first menstruation to menopause) have a lower risk of developing Parkinson's disease than women with fewer years, according to a large, new study by researchers at Albert Einstein College of Medicine of Yeshiva University. view more (2009-02-26)
Starve a yeast, sweeten its lifespan
Johns Hopkins researchers have discovered a new energy-making biochemical twist in determining the lifespan of yeast cells, one so valuable to longevity that it is likely to also functions in humans. view more (2009-03-24)
Purple tomatoes: The richness of antioxidants against tumors
Researchers from the John Innes Centre in Norwich, Great Britain, in collaboration with other European centres participating to the FLORA project, have obtained genetically modified tomatoes rich in anthocyanins, a category of antioxidants belonging to the class of flavonoids. view more (2008-10-27)
Researchers find link between food odors and lifespan in fruit flies
Researchers hoping to learn why organisms tend to live longer if their intake of calories is restricted have made a startling discovery - in fruit flies, just the smell of food can have a negative effect on longevity. view more (2007-02-02)
Tiny roundworm's telomeres help scientists to tease apart different types of aging
The continual and inevitable shortening of telomeres, the protective "caps" at the end of all 46 human chromosomes, has been linked to aging and physical decline. view more (2005-08-08)
Late motherhood boosts family lifespan
Women who have babies naturally in their 40s or 50s tend to live longer than other women. view more (2009-05-04)
Xie Lab Demonstrates Dual Intrinsic and Extrinsic Control of Stem Cell Aging
The Stowers Institute's Xie Lab has published recent findings that reveal some of the factors underlying the aging of stem cells. view more (2007-10-11)
Anti-aging hormone reduces reactive oxygen species
Scientists recently discovered an anti-aging hormone called Klotho. Now, a new study shows that this protein acts by increasing the cell's ability to detoxify harmful reactive oxygen species. view more (2005-11-04)
Researchers find natural section favors parasite fitness over host health
Why do parasites harm their hosts? Classic evolutionary theory predicts that parasites become more virulent because they must transmit themselves between hosts, yet scientists have found little data to support this idea, until now. view more (2008-05-13)
Longer-lived rodents have lower levels of thyroid hormone
The thyroid may play an important role in longevity, with longer-lived rodents showing significantly lower levels of a thyroid hormone that speeds metabolism, a new study has found. view more (2006-10-10)
Human beta-cell line offers hope for type 1 diabetes breakthrough
Transplantation of insulin-producing pancreatic beta-cells shows great promise as a treatment for type 1 diabetes, but development of this therapy has been hampered by a severe shortage of donor beta-cells, which are obtained from decreased human donors. view more (2005-09-27)
Research suggests we may be genetically programmed to care about the long-term future
Humans may be programmed by evolution to care about the future of the environment, suggests research published today. view more (2009-05-28)
Agent in red wine found to keep hearts young
How, scientists wonder, do the French get away with a clean bill of heart health despite a diet loaded with saturated fats? view more (2008-06-04)
