Scientists restored young gut bacteria in aging mice and saw signs of rejuvenation along with complete protection from liver cancer. Returning the gut microbiome to a more youthful state could help slow aging and lower the risk of liver cancer, according to research entitled “Restoration of a youthful gut microbiome reduces liver aging and suppresses [...]

Scientists are discovering that some of the cells linked to aging may also be key to staying healthy. A growing body of research is changing how scientists view one of aging biology’s most studied cell types: senescent cells, often called “zombie cells.” While these cells have long been associated with aging and chronic disease, new [...]

Scientists are investigating an unusual biological compound that may influence how the body and brain age. The Fountain of Youth may be a legend, but the search for ways to slow aging is very real. Scientists are actively exploring how to protect the body and brain over time, and a new study points to an [...]

Efforts to extend life may be succeeding, but not equally. Extending life is only part of the goal in aging research. Scientists also want more people to reach old age in good health, with fewer differences in when individuals die. This ideal outcome is often described as “squaring the survival curve,” where most deaths are [...]

A popular anti-aging therapy produced dramatic brain changes in mice. A drug pairing often promoted in anti-aging research may come with an unexpected cost in the brain. University of Connecticut scientists report in PNAS that dasatinib+quercetin (D+Q) caused significant brain damage in mice, including the loss of myelin, the fatty covering that helps nerve cells [...]
