Intel has announced the winners of its 2014 International Science and Engineering Fair (ISEF). According to Intel, the contest is the world's largest high school science research competition. The top prize went to 15-year-old Nathan Han for his software that studies the mutations of a gene linked to breast cancer.
Each year, around 7 million high school students across the globe develop and submit original research for the Intel ISEF competition. Over 1,700 participants from more than 70 countries, regions, and territories were selected to join this year's "week-long celebration of science, technology, engineering, and math".
