...Elizabeth and her mother took the only way out: they went to work. Elizabeth sat at her mother's desk and colored and cruised www.americangirl.com while her mother, a research scientist, worked in a glass-walled lab a few feet away. Elizabeth drank plenty of fluids, got lots of hugs and ate lunch with Mom in the employee cafeteria. The next day she went back to school while her mother played catch-up at work...
...event was sponsored by several Asian-American student groups who wanted to discuss racial issues surrounding the case of Wen Ho Lee, a Taiwanese-American scientist in jail on 59 counts of violating national security procedures...
...accomplice separately sells him out as well. The third option is that neither sells the other out, and each serves a sentence longer than if he had, but shorter than if he himself had been sold out. What's the best thing to do? Robert Axelrod, a political scientist at the University of Michigan, tested various strategies over a number of years and discovered that as the game is repeated over and over, a simple strategy of tit for tat tends to win: if someone gives you something, reciprocate; if no one does, don't. That's what the bats...
...monsoon is not the only climate cycle that human activity could alter. Atmospheric scientist John M. Wallace of the University of Washington believes that rising concentrations of greenhouse gases are already beginning to have an impact on another important cycle, known as the North Atlantic or Arctic Oscillation. In this case it's not the warming these gases create in the lower atmosphere that is key, but the cooling they cause in the stratosphere, where molecules of carbon dioxide and the like emit heat to space rather than trapping it in the upper atmosphere. This stratospheric cooling, Wallace and others...
Unfortunately, scientists understand very little about the dynamics of initiation points--how smooth or rough the faults are, what kind of rock is found there, what goes on just before and after a quake. Laboratory experiments can reproduce the pressures to simulate the environment at the initiation point, but without knowing the effects of pressure building up over the centuries, any attempt to release it could backfire. Says Mary Lou Zoback, chief scientist of the hazards team: "If we generated a 1906 earthquake, that would be the end of the USCG." And maybe Los Angeles...
