...risk also higher during the last part of sleep? Usually, during the night, the cardiovascular system is "sleeping," which is characterized by low blood pressure and heart rate. But the last stage of sleep - REM, or rapid eye movement, sleep [when we believe most dreaming occurs] - is a risk period for cardiovascular emergencies because when you dream, you have a dramatic increase of activity of the autonomic nervous system - even more than when you are awake. Probably each of us can remember waking up in the morning sometimes feeling very tired. That's because during that stage of dreams...
...coverage]. We have to be sure that the pill we're prescribing is still active when patients need it most. It's not as easy as simply asking patients to take pills before bed instead of first thing in the morning, because during sleep we have a low heart rate and blood pressure. If you lower your blood pressure too much during the night, you risk reducing blood supply to the brain, and that can be harmful...
...year of Bush fatigue over the Bush economy. Emory University's Alan Abramowitz has concocted a formula that has predicted the popular vote winner in 14 of the last 15 elections; it missed in 1968 but got the razor-thin margin right.

We actually had dinner with a very fine Minister of Education who is genuinely committed to education for all children, but particularly for girls. Listening to him describe not only the barriers presented by the lack of women teachers - and you've got to have women teachers to teach girls...
...just as those soccer stars caused a dramatic upset by beating France, Senegal's former colonial master, at the World Cup in 2002, so has the Scrabble squad long since bested the French at their own game. The country may have an adult literacy rate of just under 40% according to the latest U.N. Human Development index, and most Senegalese consider Wolof rather than French their mother tongue. Still, when it comes to the French-language version of the wordy board game, Senegal is the team to beat. At last year's World Championship in Quebec, the Senegalese took three...
