This week's cover of the New Yorker magazine is a witty drawing by artist Chris Ware of a playground full of young children and their watchful parents. One woman wheels her son in a stroller, only to see that all the other parents are men. The image is called "Mother's Day."
But for all the memorable New Yorker covers out there, an equally large number of covers didn't make it to the newsstand. They were not quite on the money — or were sometimes a little too coarsely on the money.
If you make your own yogurt, there's a chance your yogurt could outlive you.
That's because some bacteria that grow and feed on the sugar in milk – the process that ferments milk into yogurt — can procreate indefinitely in new generations of yogurt.
But not all yogurts have these immortal powers. The typical store-bought yogurt only carries a few strains of bacteria that have been isolated by scientists. Those bacteria on their own can't regenerate very long — maybe just for a generation or two.
