Scientists at the University of Massachussetts Amherst have figured out how to turn a smartphone into a food poisoning detector. All you have to do is add a $30 microscope attachment to your smartphone and run their app after rinsing the suspected food with water. The microscope and app work together and detect the presense of dangerous bacteria in 30 minutes. If you cook a lot of chicken, raw vegetables and the like then this would be nice to have. It's not available yet, but once it's out in the market I bet it sells well to consumers and restaurants alike. "Right now, this is really preliminary," said McLandsborough. "We can detect bacteria with the iPhone, but we don't know if they're pathogenic — if they're harmful bacteria or good bacteria."
