Unhappy with portrayals of Native Americans in mainstream media, a group of students from South Dakota's Rosebud Sioux Reservation created a video to show that their community is about more than alcoholism, broken homes and crime.

The students are visiting Washington, D.C., on Monday to lobby Congress for increased funding for schools on reservations.

Filmed in black and white, the student-produced video More Than That takes viewers through the hallways, classrooms and gymnasium of the Rosebud Sioux Reservation's county high school.

GOP presidential candidate Mitt Romney plays up his Michigan roots when he talks to voters in the state where he grew up.

In 2008, Romney won the Republican presidential primary in Michigan. On the campaign trail, he likes to tell stories about his father, George, who was an iconic governor of Michigan in the 1960s:

"He said, 'It sure is great to be in Mount Clemens today,' even though he was in Mount Pleasant. My mother was sitting behind and said, 'George, it's "Pleasant." ' He said, 'Yes, it's pleasant in Mount Clemens.' "

When a nerve is injured, it's often hard to get it to regrow fast enough to restore function.

But now researchers say they can speed up that process, so that damaged nerves can be healed in days instead of months — at least in rats.

The scientists say they've developed a technique that reconnects the severed ends of a nerve, allowing it to begin carrying messages again very quickly. Usually, severed nerves must regrow from the point of injury — a process that can take months, if it ever happens.

He thinks it's time for America to invest heavily in space exploration and research.

The halls of the State Department are haunted, not by actual ghosts, but by people who might as well be ghosts: whistleblowers, people who angered someone powerful and people who for one reason or another, can't be fired.

"People like me, that the State Department no longer wants, but for some reason can't or won't fire, are assigned to what we call 'hallwalking,'" says author Peter Van Buren.
