Alaska Natives are twice as likely to get colon cancer and die from it as the white population in the United States. When Mayo Clinic doctor David Ahlquist took a trip to Bethel, Alaska, in the mid-1990s, that startling statistic caught his attention.
"Here they had one of the world's highest rates of colon cancer and one of the world's poorest outcomes in terms of survival from cancer, because of late diagnosis," Ahlquist says.
Steven and Jeffrey Gluckstein are in a tough spot. They're brothers. They're world-class athletes. They train together six times a week, side by side, at the same gym. And only one of them can make the U.S. Olympic team as a trampolinist.
Steven, 21, is precise on the bounce mat. He rockets up to the ceiling, twists his body into a jackknife, flips around a couple times and hits the trampoline for less than a second before he shoots back up. Every time he comes down, his feet stab the red X in the center.
