The Perfect Pearl
The pearl. The only gem produced by a living animal, has long carried a certain allure. Yet the best mollusk for making this gem, the pearl oyster doesn't always produce a pearl, and even then, the pearls are rarely perfectly round. It wasn't until the late nineteenth century, when a Japanese scientist discovered a technique to incite oysters to produce these gems, that an industry was formed. Inducing an oyster to create a pearl is only half the battle—the oyster then needs a nutrient-rich, open environment in which to grow. This NOVA program looks at the science of pearl farming, follows efforts of oyster farmers trying to cope with growing problems of pollution and overcrowding, and considers the shifting sands of dominance within the pearl industry.

Then there are their kids: 18-year-old Meg is an outcast at school and the Griffin family punching bag; 13-year-old Chris is a socially awkward teen who doesn't have a clue about the opposite sex; and one-year-old Stewie is a diabolically clever baby whose burgeoning sexuality is very much a work in progress.
