Using Isotopes in Human Hair to Reveal Personal Characteristics for Forensic Investigations
Researchers investigate the potential of using isotopes in specific amino acids in human hair as a forensic tool to provide information about an individual's age, sex, race, body mass, genetic disorders, health, and region of origin.
Fiber Impurities Allow for More Detailed Forensic Fluorescence Comparisons
Fiber evidence has long been an important part of criminal cases, for it can associate a suspect with a crime scene. This project details new analytical procedures that allow fiber comparisons that are more detailed than standard forensic practices.
Defining the Difficulty of Fingerprint Comparisons
Researchers create a metric to determine the difficulty of matching latent and known fingerprints, then link that difficulty to error rates.

New Software Improves Rigor of Latent Fingerprint Examination
There is no standard method of detailed documentation of the latent print examination process, but researchers have developed software that improves the standardization and quantifiability, implemented as part of the FBI’s Universal Latent Workstation.
