...scientists race to unravel the mysteries of SARS, one issue high on their agenda will be the likelihood that the new virus is a cross-species transmission in which the virus has mutated from its animal carrier so that it can infect humans, who have no immunity from the alien invader. The most obvious examples of this are HIV and influenza, and the latter disease has disturbing parallels with SARS. The flu virus lives usually in the stomachs of waterfowl, and the two are co-adapted?the birds don't get sick. It is widely believed among virologists, however, that...
...illness usually begins with a fever of 38C or higher (sometimes with chills), headache, body aches and malaise. Patients develop a dry cough and difficulty breathing; some get diarrhea. Most people start to recover after five or six days. If you don't have symptoms, can you still infect others? It's possible. Researchers don't know enough about SARS to say for sure, but in general, viruses can be passed on for several days before symptoms appear...
...When researchers published their first highly detailed analysis of the structure of a human rhinovirus back in 1985, it was easy to imagine that a cure for the common cold might soon be available. After all, once scientists discovered which molecular footholds rhinoviruses use to latch onto and infect human cells, it should not have been that hard to develop a drug that would block the linkage and cure a cold before it got started. Or so the thinking went. Unfortunately, the logistics, from both a biological and a business point of view, turned out to be a lot more...

...will be to encourage attendance among young people. Iceman's acclaimed 1998 run, in both New York and London, featured subsidized student tickets that included some of the choicest seats in the house. "When you have a youthful, eager, excited audience in the front row, you infect the entire room with a kind of energy, and it also affects the actors," says Spacey. During Iceman - his first appearance onstage at the Old Vic - Spacey was asked to sit on the board of the theater, which had recently changed ownership. "I suspect they were reacting in part to the fact that...
