...Avian flu is a form of influenza that often kills domesticated poultry such as chickens and turkeys. Some strains of bird flu can make humans sick, too. The most dangerous is H5N1, which has caused at least 10 human deaths during the current outbreak. H5N1 first jumped the species barrier from birds to humans in Hong Kong in 1997, when six out of 18 infected people died. The fear is that H5N1 could combine with a human-flu strain to create a deadly virus that's so contagious it could cause a human pandemic...

Leading that race is legendary aerospace engineer Burt Rutan, who is gearing up for another test after his rocket plane broke the sound barrier for the first time last December.

...recorded history, no disease has jumped the species barrier to infect humans, caused an epidemic and then never threatened us again--not without the discovery of a vaccine or cure to curtail the microbe. Some diseases, such as chicken pox, gradually become endemic to man and eventually result, if we are lucky, in nothing more than a mild childhood illness. Others, such as Ebola, retreat back to whatever animal reservoir they came from, stalking humanity from their hidden lair, only occasionally lashing out to bloody a village or crash a rural hospital. But diseases do not, as a rule, just...
