Google's first-ever science fair came to a close yesterday, as 15 finalists, ranging in age from 13 to 18, showed off their smarts at Google HQ. Top honors went to three young ladies -- score one for the girls -- in three separate age groups, but there could only be one Highlander Grand Prize winner. The big win went to Shree Bose for an experiment which focused on improving treatment of ovarian cancer, following accumulated resistance to chemotherapy drugs. Lauren Hodge and Naomi Shah also took home trophies for their experiments which dealt with carcinogens in grilled chicken and reducing reliance on asthma treatment, respectively. Along with trophies built of Legos, these young brainiacs took home prizes that included lifetime subscriptions to Scientific American and big-money scholarships ranging from $25,000 to $50,000. A very long video documenting the award ceremony can be found -- featuring a shocking lack of baking soda volcanoes -- after the break.
