Last weekend in Washington, D.C., 30 young researchers from across the nation were preparing for a competition of their own.In a sense,all were winners already.After all,each had to beat out hundreds of others for the chance to face off in team play.But only one competitor—Alaina Gassler, 14—would take home the top prize: an educational award worth$25,000.Her award was one of over a dozen announced at an evening party on October 29.

Alaina was one of 30 finalists from 13 states who competed in the ninth yearly Broadcom MASTERS competition. Alaina and the other finalists had to be in sixth,seventh or eighth grade to attend the competition.What's more,their research had to be judged within the top 10 percent of all projects.Those projects all fell within the fields of science,technology, engineering or mathematics.Fifteen of the finalists took home major awards.For the first time,this year,60%of the finalists were female.

Alaina developed a system aimed at improving driving safety. “Congratulations to Alaina,whose project has the possibility to reduce the number of traffic accidents,” says Maya Ajmera,president of Society for Science&the Public,the organization that created the competition.

Alaina goes to school in West Grove,Pennsylvania. “I didn't think I'd win an award this big,” she said. For her project, Alaina developed a system that could reduce blind spots for drivers.Such areas can hide objects or other cars from a driver's view, and thus easily lead to accidents.

Alaina's system depends on a camera fixed on the front part of the passenger-side window. It's pointed so that it can monitor things a driver can't see.The camera records a video of what it's seeing and at the same time sends it to a projector fixed over the driver's head.That projector plays the video on a screen,which is fixed on the passengerside roof support.In this way,the blind spots are reduced.
