(Medical Xpress)—A long-standing assumption in aging research, and therefore in resulting antiaging interventions, is that modifying genetic and environmental factors to extend lifespan also increases healthspan – the ...
(Medical Xpress)—In the battle against aging and age-related neurological diseases such as Parkinson's and Alzheimer's, a key factor has long appeared to be the toxicity of proteins which tend to aggregate. Recently, scientists ...
Humans are unusual in that women go through menopause and stop reproducing long before reaching the end of their life expectancy. One theory holds that this aspect of human life history may be explained by the evolutionary ...

(Medical Xpress)—A team of researchers working at the University of California has found that adding the compound α-ketoglutarate (alpha-KG) to a nematode diet can drastically extend its lifespan. In their paper published ...
Swiss scientists reveal the mechanism responsible for aging hidden deep within mitochondria—and dramatically slow it down in worms by administering antibiotics to the young.

(Medical Xpress)—Replicative aging (also known as replicative senescence) causes mammalian cells to undergo a process of growth arrest dependent on telomeres (the shortening of repeated sequences at the ends of chromosomes). ...
A new study demonstrates what researchers consider conclusive evidence that the red wine compound resveratrol directly activates a protein that promotes health and longevity in animal models. What's more, the researchers ...
