Google uses Web searches to track flu’s spread

This screen shot supplied by Google of the Google’s Street View map feature, shows a portion of an art project in Sampsonia Way on Pittsburgh’s Northside. Artists Ben Kinsley and Robin Hewlett staged multiple scenes along the way for Google to capture when it sent a camera equipped car down that street in May to take photographs for its online mapping tool. The two set out to explore the boundaries of the real and virtual worlds after Pittsburgh became one of the earliest cities to be included in Street View, and Google agreed to participate after the artists contacted the company.
