| Controversial Blood Test To Predict How Long You Will Live |
| A new test set to hit the market in Britain in the next year aims to tell patients how long they have to live, and naturally that's not happening without controversy. The test measures a person's telomeres, those structures found on the tips of chromosomes. The length of telomeres apparently correlates with how fast a person is aging biologically, and hence researchers want to offer individuals some insight into just how much longer their bodies can hold up. |

| CPAP Decreases Cardiovascular Mortality in Elderly Patients |
| Continuous positive airway pressure (CPAP) effectively decreases the risk of cardiovascular death in elderly patients who suffer from obstructive sleep apnea (OSA), according to a study conducted by researchers in Spain. The study is the first large-scale study to assess the impact of OSA and the effectiveness of CPAP treatment in cardiovascular mortality in the elderly. |

| Eating less makes your brain younger |
| Our brains don't like being overfed, as obesity can age the brain prematurely and even make it more vulnerable to Alzheimer's and Parkinson's. Now we've discovered the opposite effect: a strict diet turns on molecules that keep the brain young. |

| Endocannabinoid signaling in dietary restriction and lifespan extension |
| There is no longer any doubt that dietary restriction (DR) extends lifespan. Many studies have shown that limiting nutrient intake extends lifespan in yeast, worms, flies and as well as postponing age-related diseases in mice. |

| Erasing the Signs of Aging in Human Cells Is Now a Reality |
| Scientists have recently succeeded in rejuvenating cells from elderly donors (aged over 100). These old cells were reprogrammed in vitro to induced pluripotent stem cells (iPSC) and to rejuvenated and human embryonic stem cells (hESC): cells of all types can again be differentiated after this genuine "rejuvenation" therapy. The results represent significant progress for research into iPSC cells and a further step forwards for regenerative medicine. |

| Following cancer prevention guidelines lowers risk of death from cancer, heart disease, all causes |
| A study of more than 100,000 men and women over 14 years finds nonsmokers who followed recommendations for cancer prevention had a lower risk of death from cancer, cardiovascular disease, and all-causes. The study appears early online in Cancer Biomarkers, Epidemiology, and Prevention, and was led by American Cancer Society epidemiologists. |

| Fruit fly intestine may hold secret to the fountain of youth |
| One of the few reliable ways to extend an organism's lifespan, be it a fruit fly or a mouse, is to restrict calorie intake. Now, a new study in fruit flies is helping to explain why such minimal diets are linked to longevity and offering clues to the effects of aging on stem cell behavior. |

| Great Depression did not significantly improve life expectancy in the US |
| A study published today provides a new perspective on the Great Depression of the 1930s. A widely held view is that there were remarkable improvements in life expectancy of over five years. Using data from urban populations, researchers found that it was actually associated with an increase in suicides but reduction in motor-vehicle accidents, a pattern consistent with the impacts of the current recession in Europe and the U.S. The study, led by the London School of Hygiene & Tropical Medicine, is published in today's issue of the Journal of Epidemiology & Community Health. |

| How many US deaths are caused by poverty, low levels of education and other social factors? |
| How researchers classify and quantify causes of death across a population has evolved in recent decades. In addition to long-recognized physiological causes such as heart attack and cancer, the role of behavioral factors--including smoking, dietary patterns and inactivity--began to be quantified in the 1990s. |

| Key to Aging? Key Molecular Switch for Telomere Extension by Telomerase Identified |
| Researchers at the University of Illinois at Chicago College of Medicine describe for the first time a key target of DNA damage checkpoint enzymes that must be chemically modified to enable stable maintenance of chromosome ends by telomerase, an enzyme thought to play a key role in cancer and aging. |

| New Discoveries in Cell Aging |
| Researchers have quantified with precision the effect of protein aggregation on the cell aging processes using as models the Escherichia coli bacteria and the molecule which is thought to trigger Alzheimer's disease. Scientists have demonstrated that the effect can be predicted before it occurs. Protein aggregation is related to several diseases, including neurodegenerative diseases. |

| Proteins Used to Map the Aging Process |
| Loss of muscle mass is not only associated with disease, such as HIV and cancer, but also with the normal aging process. Anabolic steroids are sometimes used to reverse loss of lean muscle tissue but they can have unwanted side effects. New research, published in BioMed Central's open access journal Immunity and Ageing, shows that nine proteins, isolated from blood, alter with age and that the profile of some of these proteins can be reversed by testosterone treatment. |

| Regular physical activity associated with lower risk of depression in old 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. |

| Researchers demystify a fountain of youth in the adult brain |
| Duke University Medical Center researchers have found that a "fountain of youth" that sustains the production of new neurons in the brains of rodents is also believed to be present in the human brain. The existence of a vital support system of cells around stem cells in the brain explains why stem cells by themselves can't generate neurons in a lab dish, a major roadblock in using these stem cells for injury repair. |

| Sea squirts could hold the secret to human immortality |
| Sea squirts might not look like much...they're simple, hermaphroditic creatures that barely even have a brain. But they have a particular knack for activating the enzyme telomerase, which protects DNA from degradation. That unexpected talent could help fight human aging. |

| Scientists Chart Gene Expression in the Brain Across Lifespan |
| The "switching on" or expression of specific genes in the human genome is what makes each human tissue and each human being unique. A new study by researchers at the Johns Hopkins Bloomberg School of Public Health, the Lieber Institute for Brain Development, and the National Institute of Mental Health found that many gene expression changes that occur during fetal development are reversed immediately after birth. |

| Animals that reproduce asexually by somatic cloning have special mechanisms that delay ageing provide exceptionally good health. Scientists at the University of Gothenburg have shown how colony-forming ascidians (or sea squirts) can activate the enzyme telomerase, which protects DNA. This enzyme is more active also in humans who attain an advanced age. |
