Long considered immortal, bacteria are showing that they can fall victim to aging

Abstract: Like us, some bacteria age, although scientists long believed they couldn't. Theoretical studies suggest that unequal division is the prerequisite for aging, and a new study of an asymmetrically dividing bacterium backs the argument. Starvation also provokes aging in some bugs, causing them to start producing proteins that are vulnerable to oxidative damage. Deprived bacteria deploy defenses against oxidation that are similar to those in worms and higher organisms. Bacteria's ability to survive brutal conditions might clue scientist in to ways to make our own cells resist aging.
