Here's something to drink to: easy access to water fountains and a nudge from teachers to use them might help kids stay lean. A new study published today in Pediatrics suggests that installing fountains in elementary schools and pushing students to drink more water may reduce their risk of being plump by as much as a third.
"Drinking fountains won't solve the obesity epidemic, but they could be effective components of the solution," says study co-author Rebecca Muckelbauer, a nutritionist at the Research Institute of Child Nutrition Dortmund in Dortmund, Germany.
Muckelbauer and her colleagues studied the water-drinking habits of nearly 3,000 second and third graders attending schools in the neighboring cities of Dortmund and Essen during the 2006-2007 academic year. At the beginning of the school year, the researchers had water fountains installed in 17 of the schools and worked with teachers to implement educational programs to promote water drinking. (In contrast to U.S. schools, few German schools actually have water fountains, according Muckelbauer). The researchers surveyed the children about their drinking habits and measured their heights and weights at the beginning and end of the school year.

If you missed our coverage of the 2009 Intel Science Talent Search finalists and winners earlier this week—or even if you didn't—below you'll find a package of whiz kid profiles. Spending time with them is enough to turn a hardened cynic into an optimist who believes that the next generation has a chance of solving many of the world's problems. Christie Nicholson, who produced the videos, and Laura Vanderkam, who did the interviews, will agree.
There's Aditya Rajagopalan, who figured out how to improve the way we make cellulosic ethanol (and had a few words for the President). There's Chelsea Jurman, who took fifth place out of 40 finalists and suggests that parents don't say too much about their own drinking to their kids. There's Philip Streich, who took third place in the competition, for his project on carbon nanotubes.

WASHINGTON, D.C.—If you drank as a teenager, do not tell your kids about it. That’s the lesson from Chelsea Lynn Jurman’s study of teen drinking behavior—the only social science project among the 40 finalists in the Intel Science Talent Search going through the final judging rounds here this week.
“The perception kids create becomes the reality,” says Jurman, 17, a senior at Rosyln High School in New York—and if they perceive that you drank and turned out okay, they figure they will, too.
ScientificAmerican.com is on hand to speak with several of the finalists in this prestigious national competition that is the modern incarnation of the old Westinghouse Science Talent Search, which began in the 1940s. The 40 finalists get scholarships ranging from $5,000 to the top prize of $100,000. You can read about past finalists in our "Where Are They Now" series, and follow along as we live-Twitter from Washington.
