Two treasure hunters say they've found a Nazi train thought to have gone missing in Poland while laden with gold, jewels, and weapons. They aren't revealing the precise location of the train, though, until a demand about the loot is granted. Shorter Women Have Shorter Pregnancies: The height and weight of a newborn baby is largely governed by his or her own genes, but it's the height of the mother that's giving researchers a telltale sign. Specifically, shorter women have shorter pregnancies and thus more premature babies. Here's why the find has major health implications. Bad News for Workaholics: If you're putting in more than 55 hours a week at work, the chances are good that you're working toward having a stroke, researchers say.
