...National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Mich., says it's revising its formulas to better reflect real-world representations of "driving cycles": that is, up hills, down hills, acceleration rates, city miles and highway miles - the driving conditions that affect fuel efficiency or, in the case of hybrids and electric cars, how long the battery will last. This is why the EPA says it "cannot confirm" GM's mileage claims but is happy the company is innovating such fuel-efficient cars...

Recent evidence suggests that visceral fat cells are active, unlike the fat cells found elsewhere in the body just under the skin, known as subcutaneous fat. Those fat cells are essentially just storage sinks for calories. But visceral fat cells actively secrete hormones and other agents that affect the metabolism of sugar and the way the body burns calories. In people, visceral fat has been linked to metabolic changes, such as higher blood pressure and blood-sugar levels, that increase risk for diabetes and heart disease...
...This study shows that psychological stress, which we know can affect stress-hormone levels, can have a fairly rapid influence on where extra calories go," he says. "I'm generally quite cautious about animal research, but here I think we're seeing something that has direct relevance to human health as well...
