...shift to plug-in cars could also help the development of renewable power, all the more important since a proliferation of electric cars would alter the national pattern of carbon emissions - the utility sector would take on the emissions that once belonged oil-based transport. While a power grid fueled by solar or wind would be clean, one of its key drawbacks is that it would also be intermittent - if the sun were shaded or the wind failed to blow, we wouldn't have power. Likewise, if solar or wind produced more power than the grid could use, that excess...
...even with infrastructure improvements, the shift to electric cars is likely to take years, even decades. According to Alan Madian, a director at the research firm LECG, even assuming solid growth, we can't expect more than 68 million plug-in hybrids by 2036, which would account for less than 17% of the total estimated fleet at that time. Given that the U.S. car fleet is likely to have grown to over 400 million vehicles by then, we may still end up using more oil in the future than we do today in a business as usual scenario. That...
...think the benefits of gastric bypass may indeed be greatest in those obese patients who are recently diagnosed with diabetes, since their bodies are more likely to revert back to normal sugar metabolism after surgery. That's because much of the post-bypass weight loss is spurred by a shift in the hormonal feedback loop that controls hunger and 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...

But in the meantime, Obama had to defend himself against charges of sexism at a Virginia library appearance that was originally designed to increase his appeal among women voters. It almost did not matter that McCain had prompted a backlash from the members of the press who repeatedly pointed out that both claims were wildly misleading. The sex-education bill in question had called only for age-appropriate...
