    Hot, Hotter, Hot: Climate seesawed during dinosaur age

    Dinosaurs, too, endured climate change. Although scientists had speculated that the world some 120 million years ago was unvaryingly hot, climate fluctuated dramatically, a new report argues. Twice during a 250,000-year period in the reign of the dinosaurs, tropical sea-surface temperatures varied by 6°C, the findings suggest. That's twice as much variability as is known to have occurred at any...

    When Kids Eat Out

    Adolescents are increasingly dining out on fried foods, a new study finds, and the older they are the more frequently they do so. Those trends may portend hefty risks down the line, the authors argue, because the youngsters who ate out most often were generally the heaviest kids and they gained the most weight over the course of a year.These are worrisome prospects in this nation, where obesity...

    Science News of the Year 2002

    A year of twists and turnsWhat the world needs, say some people, is more one-handed scientists. That way, reports would have fewer sentences starting, "On the other hand. . . ."Actually, scientists need all the hands they can muster.
