Irish teenagers Ciara Judge, Émer Hickey and Sophie Healy-Thow, all 16, have won the Google Science Fair 2014. Their project, Combating the Global Food Crisis, aims to provide a solution to low crop yields by pairing a nitrogen-fixing bacteria that naturally occurs in the soil with cereal crops it does not normally associate with, such as barley and oats. The results were incredible: the girls found their test crops germinated in half the time and had a drymass yield up to 74 percent greater than usual.
