It's a simple enough idea: Know how many calories are in those fast food meals, and you'll make a better choice between them.

But when students at the Columbia University School of Nursing tried to nail down the calories on 70 menus at 12 eateries in New York's Harlem neighborhood, they found it pretty much impossible, even with a calculator.

The Obama administration is seeking to try a Lebanese man linked to Hezbollah in a military commission, expanding the reach of the military tribunal beyond al-Qaida and Taliban suspects for the first time.
