Voters in southern Arizona's 8th Congressional District are deciding who will fill the seat formerly held by Rep. Gabrielle Giffords. The Democrat resigned in January, a year after she was badly injured by a gunman at a district event in Tucson.

Four years ago, Zimbabwe experienced one of the worst cases of hyperinflation in history. The country abandoned its own currency and switched to the U.S. dollar â€” a move experts say prevented a complete economic collapse.
