Perceived Overprotection: Support Gone Bad?

Old cells gone bad

he rising incidence of senescent cells during aging may promote cancer development, according to Judith Campisi (Lawrence Berkeley National Laboratory, Berkeley, CA) and colleagues. They propose that evolution may have selected a useful function for cellular senescence early in life—the switching-off of cells that are prone to becoming cancerous— without any consideration of how these cells mig...
