In Albuquerque, visitors must decide between red and green chilies, but last week, a different kind of spice heated up the town. At the 2007 Intel International Science and Engineering Fair (ISEF), more than 1,500 high school students from 51 countries displayed projects with tongue-tingling titles.

Students competed for more than $4 million in scholarship money, computers, trips, and other awards. The big-enchilada prizes went to Dayan Li of Eleanor Roosevelt High School in Greenbelt, Md., Philip Vidal Streich, a home schooled student from Platteville, Wis., and Dmitry Vaintrob of South Eugene High School in Oregon.
