Although researchers are still a long way from understanding exactly how sleep affects memory, they are certain that getting too little sleep is a detriment. A 2007 paper in Nature Neuroscience reported that in addition to consolidating recently learned memories, "sleep before learning is equally important in preparing the brain for next-day memory formation." The study found that people who had skipped a night's sleep fared worse at making new memories the next day, compared with those who had gotten a good night's sleep. Turns out, Mom's advice may have been right all along...
...slowly being recultivated by returning locals. Insects shriek from the thick jungle beyond. The rangers have discovered that they can get a weak signal - just enough to send text messages to family or friends - if they strap their cell phones to lengths of bamboo driven into the ground at certain points around the camp. So outside every tent there are phones on sticks, like tribal totems...
...There is also concern that growth will slip backward once China's recession-fighting stimulus is scaled back. One reason Xu's minivan sales have accelerated is government tax breaks and rebates offered on certain car purchases - incentives that won't last forever. State subsidies have also been given to rural residents to spur sales of refrigerators and washing machines. Though the government is implementing longer-lasting plans to convince citizens to spend more money (including a $125 billion program to improve national health care, especially in less developed regions), those efforts will take years to reach their full impact...
...have the biggest impact on investors' portfolios. This is because, Prechter argues, standard economic models of financial markets depict prices as reflections - imperfect, perhaps, but still reflections - of true value. He believes instead that "waves of social mood are the driving factor" of both market moves and, to a certain extent, economic reality. He calls this approach socionomics, and he's doing what he can - his Georgia operation now includes a socionomics institute - to push it onto academic curriculums...
There's even a push in Congress to let employers further link lifestyles to insurance premiums. Right now companies that run their own insurance programs can reward employees with bonuses or premium reductions of up to 20% if they meet certain health guidelines. John Ensign, Republican Senator from Nevada, and Tom Carper, Democratic Senator from Delaware, co-sponsored an amendment to the current health care bill that would raise the limit to as high as 50%. The Senate Finance Committee gave it a thumbs-up in September...
