Do bacteria age? Biologists discover the answer follows simple economics

ScienceDaily (Oct. 27, 2011) — When a bacterial cell divides into two daughter cells and those two cells divide into four more daughters, then 8, then 16 and so on, the result, biologists have long assumed, is an eternally youthful population of bacteria.
