Writing in the New York Times’ Well column, Gretchen Reynolds reports on research conducted at the University of Texas Southwestern Medical Center in Dallas that suggests that exercise encourages cells in our bodies to clean up the kind of cellular waste and debris whose buildup may contribute to aging. Like much of the research that is reported here, these experiments studied two groups of mice. One group had a cell cleaning system that functioned poorly, and one group had a normal healthy cell cleaning system, the kind that allows our bodies to eliminate waste and useless debris from cells through a process called autophagy. The Texas researchers tricked out the mice so that the membranes involved in autophagy would glow when they were active. When the mice were put on a treadmill for 30 minutes, the cleaning [...]
