    Unpacking the Baggage

    Sorting out nature and nurture

    With a population of 8,195, the town of Oberlin, Ohio, is hardly a booming metropolis. But according to Sara Jaffee, an assistant professor of psychology who grew up there, its smallness is deceptive. Walk into a public school, and it feels like you’re in a city. “It’s surprisingly diverse,” she says.

    Celestial Fossils Found

    Penn researchers discover of three of the faintest and smallest objects ever detected beyond Neptune.

    When we think of our solar system, we normally picture the Sun ringed round by nine planets and assorted moons, comets, and asteroids.

    La Difference

    Smaller portions may explain the “French paradox" of rich foods and a svelte population.

    Just 7 percent of French adults are overweight, as compared with 22 percent of Americans, and proportionally far fewer people die of heart disease in France. For more than a decade, American dieters and scientists have wondered--not with a little envy--how the French get away with eating rich sauces, buttery croissants, and creamy cheeses and still remain thinner and healthier.
