...obtained an unprecedented waiver of U.N. restrictions for his flight into Libya Thursday, the move may signal a wider crisis in Washington's use of sanctions: "Sanctions tend to work for a limited period, after which they inevitably begin to collapse," says Dowell. "Washington's long-term sanctions against various countries have been very unpopular around the world, and their value has often been questionable." But with U.S. standing in the region at a low ebb following the Iraq crisis and the collapse of the Mideast peace process, there may not be much Washington can do to keep gentleman callers...
Gone are those days when many groups' titles actually reflected the identities of the various lead singers. Groups with names like Gloria Estefan and the Miami Sound Machine, Lisa and Cult Jam and D. J. Jazzy Jeff and the Fresh Prince were all staples of the '80s music arena. And although we never knew who actually made up the Miami Sound Machine, we at least knew a little bit about the band just from the name. In those days, if George Michael was singing, the casual listener generally knew...
...lusciously cynical switch, the amendments that various G.O.P. Senators had tacked on to make the bill more palatable now made it easier to deride as a huge, mangled monument to Big Government. And so Lott spun in place and called for a vote on whether to let the bill come to the floor, knowing full well that McCain did not have the 60 votes he would need. And with that, any chance of passing a comprehensive bill died, stalling the engine that was meant to power the last two years of the Clinton presidency...
Instead of assigning various segments of the genome to hundreds of scientists, as the Genome Project does, Venter plans to use what he calls whole-genome shotgunning. Essentially, he will put the entire genome in a dicer that will chop it into millions of segments. These chunks will be fed into 230 newly developed Perkins-Elmer robotic machines that will identify and sequence the DNA code letters in each segment. The company claims that they are 10 times more efficient than current sequencing machines and allow human operators to input in 15 minutes what used to take 24 hours...
First, some background. Scientists have long known that HIV is devilishly effective at fending off antibodies lobbed at it by the body's immune system. One way the virus does that is by mutating rapidly, changing the various amino acids that make up its outer shell and thus forcing the body to churn out millions of new antibodies, all of which may become ineffective with the next mutation. Some parts of the virus don't change, however; if they did, HIV would rapidly lose its power to infect. If scientists understood more about those parts, they could use them...
