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 "...

Caloric restriction won't dramatically extend life span in humans: UCLA research

Severely restricting calories over decades may add a few years to a human life span, but will not enable humans to live to 125 and beyond, as many have speculated, evolutionary biologists report. "Our message is that suffering years of misery to remain super-skinny is not going to have a big payoff in terms of a longer life," said UCLA evolutionary biologist John Phelan. "I once heard some...

Fluorescing lab worms signal longer life spans

University of Colorado at Boulder scientists have used a fluorescent marker to predict the individual life spans of identical worms that were genetically engineered to illuminate stress levels, implying living organisms have "hidden physiological states" that dictate their ability to deal with the rigors of life. According to CU-Boulder Research Associate Shane Rea, the genetically identic...

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...
