Increased Life Expectancy May Mean Lower Fertility (2/19/2008)

One of the benefits of postindustrial life is that it is largely free of the fear of early mortality. However, a curious side-effect of this confidence seems to be a dramatic reduction in birthrates. Writing in the journal Science, Professor Ruth Mace (UCL Anthropology) draws a clear correlation between increased life expectancy and lower fertility in cities. ...> Full Article

Studies Identify Modifiable Factors Associated With Exceptionally Long Life (2/12/2008)

A healthy lifestyle during the early elderly years-including weight management, exercising regularly and not smoking-may be associated with a greater probability of living to age 90 in men, as well as good health and physical function, according to a report in the February 11 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. A second article in the same issue finds that although some individuals survive to 100 years or beyond by avoiding chronic diseases, other centenarians live with such conditions for many years without becoming disabled. ...> Full Article

Researchers Uncover Genetic Components of Aging (8/27/2007)

People who live to 100 or more are known to have just as many-and sometimes even more-harmful gene variants compared with younger people. Now, scientists at the Albert Einstein College of Medicine of Yeshiva University have discovered the secret behind this paradox: favorable "longevity" genes that protect very old people from the bad genes' harmful effects. The novel method used by the researchers could lead to new drugs to protect against age-related diseases. ...> Full Article

Gene Deficiency is a Protective Barrier to Obesity (7/2/2007)

A search for the molecular clues of longevity has taken Mayo Clinic researchers down another path that could explain why some people who consume excessive calories don't gain weight. The study, which was done in laboratory mouse models, points to the absence of a gene called CD38. When absent, the gene prevented mice on high-fat diets from gaining weight, but when present, the mice became obese. ...> Full Article
