...hint. The 23rd European Union-Russia summit on Friday was held in the Russian Far East city of Khabarovsk, a former Tsarist army outpost just a few dozen miles from the Chinese border and 5,000 miles east of Western Europe. The location seemed more aimed at inducing jet lag and awe at Russia's size than at forging agreement on energy, an issue that has consistently soured relations between the two powers over the past months - and which the summit failed to resolve...
...Drank's ingredients could stir an even bigger controversy. Melatonin, valerian root and rose hips give Drank its calming effect. Melatonin is a hormone that is sometimes used to treat insomnia and jet lag. A medicinal herb, valerian root relaxes the central nervous system and can quell anxiety. The rose hips provide antioxidants. But do I really want to buy a pharmacological mix at 7-Eleven? Is it safe to drink this cocktail over the counter? "I would not recommend it," says David DiPersio, clinical pharmacist at the Vanderbilt University Medical Center. "Valerian roots and rose hips are not really...
...published every four years since the early 1970s, show that while young minorities have made academic gains, concurrent improvements in the performance of white students have kept the achievement gap consistently wide. Among high-school-age students, that gulf translated to a roughly two to three school-year lag in achievement, according to a U.S. Department of Education official quoted in the New York Times. Despite the persistence of these inequities in academic achievement, “the NAEP results are encouraging news,” said Ronald F. Ferguson, director of Harvard’s Achievement Gap Initiative...
...years longer than men to attain the rank of professor, depending on the size and nature of their school, with the largest gap at private colleges and universities. "That's a staggering difference," says lead author Kathleen Woodward, an English professor at the University of Washington. Worse, the lag time is getting longer. Women now earn more doctorates than men and make up a greater proportion of associate professors, but they're rising through the ranks more slowly than they used to: women promoted in the 1990s took an average of 7.4 years to become full professors, while those promoted...
What Causes Jet Lag? In a study in the current issue of Biology, researchers report that they've figured out the cause of jet lag: a desynchronization of the internal clocks of two groups of neurons deep in the brain. One group is associated with deep sleep, which results from fatigue; the other is linked with rapid eye movement, or REM, sleep. Although the first group of neurons can be reset in a few days, the latter can take up to a week to catch up - so, one part of the brain thinks its in Paris, while the other insists...
