Physorg -- Using a new laser technique, Jim Moran and his colleagues at Pacific Northwest National Laboratory, have devised a method of separating out the parts of hair samples that can reveal details about the recent history of the person to whom it belongs. In their paper, published in Rapid Communications in Mass Spectrometry, they describe a process they’ve devised whereby hair samples are pulled apart, rather than burned as a whole before being measured by a mass spectrometer. Such a process could be used to reveal personal details about someone, such as what they eaten recently; clues that might provide forensic scientists insight into the behavior of victims of foul play for example, or reveal information as the whereabouts of the accused during the time frame surrounding a crime.
