JUST GOOGLE IT: Olivia Hallisey, a 16-year-old American, has won the Google Science Fair with a versatile Ebola assay card. (See it in action here.) Unable to test on the actual virus or Ebola patients, Hallisey created an approach that recognizes a protein from the virus. She beat thousands of other 13-to-18-year-olds from all over the world to advance to the round of 22 finalists and triumph. Projects from the runners-up included included a water purification system and a textbook question generator. See the full list of winners and their projects here.
