Space dust, magnetic storms, solar winds and the Earth's atmosphere all create drag, which slows down the planet. Even the amount of snow covering the polar ice caps adds to the rotational lag. But one of the main obstacles is tidal friction. Because the gravitational pull between the moon and the Earth is not uniform, the tidal force stretches the Earth - core, mantle, crust, oceans and all - producing bulges. The Earth's rotation pushes the tidal bulge slightly ahead of the Earth-moon alignment; the moon's gravity, however, yanks the bulges back to keep them in line. This...
...campaign trail, Obama frequently applauded what Duncan has accomplished in Chicago, long considered to have one of the country's most challenging school districts. Under Duncan's watch, the city's schools for the past seven years have seen increases in some state test scores, though they continue to lag behind the Illinois average. But the graduation rate has risen 6%, and 53 new schools have opened. Duncan has spearheaded merit-pay incentives for both teachers and students as well, and suggested opening the country's first gay-friendly high school. In each of these endeavors, he has tried...

The drug hasn't been federally approved yet, but you may find similar benefits in taking melatonin - tasimelteon mimics that naturally occurring hormone...
...Alaska, Arkansas, Montana, North Dakota, Oklahoma, Texas and West Virginia. Many of those states have economies tied to energy or agriculture - two sectors that held up better than most for longer but have been showing weakness this year as the price of commodities has plummeted. State finances tend to lag the national economy, so strength so far is no guarantee things will stay rosy. Of legislative fiscal officers surveyed, including one in Puerto Rico, 26 were pessimistic about the revenue outlook through next summer; last year at this time, none were. Of the remaining officers, 19 were concerned...
Situations like Buck's may make this new research all the more attractive. Better yet, consider the case of Sarah Krasnoff, probably the world's most extreme jet-lag sufferer. In 1971, caught up in a custody dispute over her teenage grandson, Krasnoff learned that she was not subject to custody laws in the sky. That summer, she made about 160 continuous flights between New York and Europe with her grandson. By the end of the summer, Krasnoff, 74, collapsed and died of a heart attack...
