Got an idea for a world-saving app? This year the Imagine Cup has new categories and twice as much prize money.
Student innovators, start your engines. Registration's now open for Microsoft's annual Imagine Cup, the world's biggest technology competition for students. Entering its 11th year, the competition invites high school and college students to use their tech skills to solve the world's biggest problems. Student teams from around the globe have created everything from a smartphone app that diagnoses malaria to an app that reduces food waste by connecting leftover meals from restaurants with homeless shelters.
