China's Xinhua news agency reported in March that the police department in Nanjing has gone beyond fingerprints and now has a data bank of smells taken from criminals and crime scenes to aid police dogs in investigations. Officials say that storing the scents at minus-18 degrees Celsius retards degradation for at least three years, and already, they say, the bank of 500 odors has led to the identification of 23 suspects.
