Researchers extend mouse lifespan by protecting against free radicals
Scientists at the University of Washington and their colleagues at other research centers have found a way to significantly extend the lifespan of mice while reducing the impact of the aging process. Their study, which will be published online by the journal Science on May 5, lends more credence to the free-radical theory of aging. The theory suggests that very reactive chemicals, called "...New lifespan extension genes found
New genes tied to lifespan extension in yeast have been identified by researchers from UC Davis and Harvard Medical School. Drastically reducing calorie intake, or caloric restriction, is known to extend the lifespan of species including yeast, worms and rodents. Previous research linked a gene called Sir2 with lifespan extension due to caloric restriction, but worms and yeast that lack Si...MicroRNA gene that regulates lifespan found by Yale scientists
Genes that control the timing of organ formation during development also control timing of aging and death, and provide evidence of a biological timing mechanism for aging, Yale researchers report in the journal Science. "Although there is a large variation in lifespan from species to species, there are genetic aspects to the processes of development and aging," said <a href="http://www.y...Fish evolve a longer lifespan by evolving a longer reproductive period, researchers find
A UC Riverside-led research team has found that as some populations of an organism evolve a longer lifespan, they do so by increasing only that segment of the lifespan that contributes to "fitness" ?the relative ability of an individual to contribute offspring to the next generation. Focusing on guppies, small fresh-water fish biologists have studied for long, the researchers found that gu...Resveratrol prolongs lifespan and delays onset of aging-related traits in a short-lived vertebrate
By studying a particularly short-lived fish species, researchers have been able to show that a natural compound previously shown to extend lifespan in non-vertebrate organisms can also do so in at least one vertebrate species. The findings, reported by Alessandro Cellerino of the Scuola Normale Superiore, Pisa, and colleagues, support the potential utility of the compound in human aging research....Eye Disorders, A Predictor Of A Shorter Lifespan
People with age-related eye problems, such as age-related macular degeneration and cataracts may not live as long as those without them, // says a new study. A cataract involves the lens of the eye becoming cloudy and can cause partial blindness. In a study of 4,753 people aged 55 to 81, people with macular degeneration, a progressive condition that causes gradual vision loss, had a 41-p...Friendship can extend lifespan
More than family bonds, its friendship that can keep people have a long life//. An Australian research study have pointed out that the benefits of having friends do affect the health and emotional well being of people so much so that life expectancy can get significantly increased. The researchers had surveyed about 1500 people about their social contacts, in person or over...Lifespan And Height Interlinked With Juvenile Diseases.
A study conducted by Crimmins and Finch showed the effect of childhood infections and inflammations on reduced height and risk of developing cardiovascular diseases // . They collected mortality data of individuals from four European countries- Sweden, France, England and Switzerland from different years but ending with individuals born in 1899. After that in 1900 modern medicine was an...Males Lifespan Shortened By Elevated Levels Of Testosterone
According to a new research, men who have elevated levels of testosterone may be successful as far as progeny is concerned but may lead shorter lives// when compared with men who secrete normal level of the hormone. According to foodconsumer.org, comparative studies have studied testosterone levels and related them to mating systems and aggression, but very few studies have attempted...
