This paper is interesting as a first step on the way to further research into compensatory therapies that can reduce the cardiac muscle dysfunction of heart failure. One-time radiation therapy appears to persistently change cardiomyocyte behavior via altered epigenetic regulation of notch signaling, leading to modestly improved heart tissue function. […]

How much of the benefit of a healthier diet arises from the effects of natural calorie restriction mimetic compounds? That question is an interesting one from a scientific perspective, but the answers are probably not all that valuable in a practical sense. We have a fairly good idea as to […]

Theory and modeling dominates the study of the evolution of aging, as is the case in any field in which one is presented with a snapshot of a very complex environment and no ability to conduct directly relevant experiments on that environment. Beyond the state of the natural world here […]

The gut microbiome is important in health and aging. Populations of microbes change with age, favoring harmful inflammatory populations at the expense of populations that generate beneficial metabolites. Restoration of a youthful microbiome via fecal microbiota transplantation has been demonstrated to be beneficial in animal studies. The research community is […]
