...satiety. Production of certain weight-related hormones, such as ghrelin, or the hunger hormone, are directly reduced by the patient's physically smaller stomach (ghrelin is produced by glands in the stomach), leading to a reduction in food intake. Meanwhile, the smaller stomach more readily triggers hormones that signal satiety to the brain, sending the message that the body has taken in its fill of calories. But the longer this system has been overwhelmed with too much sugar and too many calories as occurs in diabetes, experts suspect, the more difficult it is to normalize the body's metabolic thresholds...
...NBCs Meet the Press. Even Kerry, whose support for abortion rights is much stronger than Biden's and who was running at the top of the ticket, never generated attention from more than a handful of the most extreme bishops. The involvement of the bishops conference is a clear signal that the communion wars are not over. And it has Catholics Democrats worriedly asking themselves: Can one of their own ever again win national office...
...proposal by Senators Joe Biden, the Democrats' vice-presidential candidate, and Republican Richard Lugar could signal a new start. Their bill calls for a tripling of nonmilitary aid to Pakistan over five years and ties security aid to improved results in dealing with terrorists.

...Force has always been the shiniest, most hardware-centric of the nation's military services. Whether it's the brooding bat-like B-2 bomber, the razor-sharp F-22 fighter, or the constellation of satellites that transmits everything from war plans to the GPS signal telling you where you are, the flyboys spare almost no expense in outfitting themselves with the state-of-the-art armament. This year, the Air Force is spending close to $65 billion - more than either the Army or Navy - developing new weapons. So at a time when politicians never tire of declaring their unbridled...
...winning over 40 percent of the grants it has applied for, according to Broad. Reflecting this success, Broad researchers announced just this week that they had received a six-year $86 million grant from the National Institutes of Health to support research to identify and develop molecular tools to signal pathways and cellular processes crucial to human health and disease. In light of its early and unchallenged success, the Broad Institute will now transition to a permanent non-profit organization, with both Harvard and MIT continuing to help govern it. Lander said that the nature of a permanent endowment will...
