Inside each cell is a dynamic world of molecules and chemicals, signals and receivers, and construction and destruction. With all this activity, it's inevitable that cellular parts get worn down over time. 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.
