Aging

Investigating trajectories of aging using high-dimensional phenotyping in mice

Despite centuries of effort from philosophers, physicians and biologists, the answer to the seemingly simple question “what is aging?” remains elusive. Some even posit that aging represents a phenomenon too expansive to ever be succinctly defined. A new study tackles this question by profiling hundreds of phenotypes across age in mice and examining how the trajectories of these phenotypes are altered by geroprotective genetic and dietary interventions.
