2014 Google Science Fair Grand Prize: An Agricultural Revolution?

When Sophie Healy Thow, Emer Hickey and Ciara Judge were told that their science fair experiment had "no point" because "it wouldn't work," the three budding scientists figured they would just find out for themselves. The result: a scientific breakthrough that could help wheat, barley and other "cereal crops" produce a dramatically higher yield. For their intellectual curiosity and perseverance, the three Irish teenagers were also the Grand Prize winners at the 2014 Google Science Fair. Healy Thow explains their project to Boyd and what it could mean for agriculture in the developing world.
