It's difficult to build a working four-rotor helicopter that spans 100 feet and only weighs 80 pounds. It's even harder when your engine is a 0.7-horsepower person. But two teams of young engineers hope to do just that.

A handful of AIDS cases were first recognized in the U.S. at the beginning of the 1980s. By 1990, there was a pandemic. In 1997, more than 3 million people became newly infected with HIV. A multimedia chart lets you track the cases by country over time.
