A California woman recently became the first person in the West to receive a new type of bionic eye, an implant that will help her see for the first time in nearly three decades.
Scientists in California's Central Valley are testing the nutrient content of fruits grown with less-than-normal amounts of water. And the findings so far are raising a question: will consumers buy fruits that are just as nutritional, or sometimes higher in antioxidants, if they aren't as pretty?
