A five-time champion in the UFC, the premier promoter in the fast-growing sport of mixed martial arts, Couture, 46, is an aging man in a sport that can obliterate even young, healthy bones. As such, he amounts to a litmus test for the next wave of young MMA athletes, who have to wonder, how long can we hang around this grueling sport? Mixed martial arts, after all, is a violent sport that combines wrestling, boxing, jiu-jitsu and other forms of combat fighting. So in spite of the money he can make...
When the virus entered the United States last April, the Centers for Disease Control issued test kits to physicians around the country to record confirmed cases. But by late July, doctors stopped individual reporting, saying the flu strain had become so extensive that maintaining such detailed surveillance was time-consuming and likely underestimating the true number of flu cases in the U.S. The Alabama Department of Public Health came up with a new plan: tracking the virus through school absentee records, voluntarily shared by individual districts.

At the moment, officials don't know how many people have actually been infected with the virus; they can only count people who are sick enough to see a doctor or come to a hospital. For every person who shows up in a hospital...

The first volunteers to test the new vaccine were inoculated in August, and because most people will not have any existing immunity to H1N1, it will require two shots, spaced three weeks apart, to educate the immune system to recognize H1N1, and another six to eight weeks after that to generate true immunity to the virus. That's when scientists will know if the vaccine provided enough protection to allow the bottled inoculations to be shipped. After decades of making flu vaccines, the scientists are sure they know what they're doing. Indeed...
