Once blamed for aging, ROS molecules may actually extend life

(Medical Xpress) -- In a new study, Yale University researchers have identified a pathway by which reactive oxygen species (ROS) molecules, which are usually implicated in the aging process due to their damage to DNA, can also act as cellular signaling molecules that extend lifespan. The study, which provides insights into the underlying mechanisms of the ROS signaling process, is published in the June issue of Cell Metabolism.
