There's apparently a new fingerprint technology out which could provide information on a suspect's diet, sex and race. The technology site www.gizmag.com reports that gelatin tape is used to remove a fingerprint for analysis under a spectroscopic microscope. Residues found could indicate if the suspect had come into contact with gunpowder, narcotics or biological or chemical weapons. Or, in the example cited in the report I read: Strong traces of urea, a chemical found in urine, could mean the fingerprint belongs to a male. Ewwwh. Not quite sure where the ability to distinguish race will come from - curry anyone?
