Living organisms experience various stresses during their lifespans. These stresses include radiation, ultraviolet rays, and chemical substances which directly damage DNA and cause cancer. Organisms are able to speedily repair … Continue Reading Study identifies genes which control cellular senescence.
Age is the largest risk factor for numerous pathologies, ranging from neurodegeneration to cancer. These pathologies likely arise from a loss of tissue homeostasis driven by one or more basic … Continue Reading New role for mitochondria identified in cellular senescence and aging.
Human DNA accumulates damage over time, and older people’s bodies can’t repair it as well. Many scientists believe a build up of damage can cause cells to enter an irreversible … Continue Reading Study identifies molecular link between DNA damage and premature aging.
