Thankfully, cells have evolved an efficient recycling process that breaks old parts down to their building blocks, which can then be repurposed and reused. Christina Towers, Ph.D., is an expert on this recycling process, called autophagy.<\/p>\n<p>\u201cThe word literally breaks down into \u2018auto,\u2019 which means self, and \u2018phagy,\u2019 which means eat,\u201d explains Towers, an assistant professor and holder of the Richard Heyman and Anne Daigle Endowed Developmental Chair at Salk. \u201cAnd it\u2019s a highly conserved process\u2014from plants to humans.
