This month's State of the Union Address was unusually short of sweeping, long-range promises, but President Obama did endorse the ambitious goals of Vice President Biden's "Moon Shot" against cancer. The disease takes hundreds of different forms and varies from person to person. The Vice President says he can't promise a single "cure." Instead, his "Moon Shot" is aimed at doubling the rate of progress toward prevention and treatment -- by replacing competition with collaboration. When cancer researchers don't share information, he's learned, promising work can be lost in what scientists call the "Valley of Death." With profit-making companies entitled to guard their secrets, we hear how a master politician is coping with "cancer politics."
