...Emmanuelle Beart take a wide variety of parts, and nobody gets upset if they switch genres. Hollywood is, of course, different. There are stars, and then there are all those other people--actors. But occasionally stars want to prove their seriousness. Art stirs in their breast like an edifying influenza, and they take on roles outside their expected range.

After receiving his degree he moved to the University of Michigan to work with Dr. Thomas Francis Jr., one of his former professors. There he helped to develop commercial vaccines against influenza that were used by American troops during World...

Even garden-variety flu can be deadly to the very old, the very young and those with weak immune systems. But every so often, a highly lethal strain emerges -- usually from domesticated swine in Asia. Unlike hiv, flu moves through the air and is highly contagious. The last killer strain showed up in 1918 and claimed 20 million lives -- more than all the combat deaths in World War I. And that was before global air travel; the next outbreak could...
