Fingerprints have led to many a criminal\u2019s downfall.<\/strong><\/p>\n Tips of our digits leave evidence for a very long time helping detectives link the perp to the crime. Alas, gloves are now de rigeur for all but the clumsiest.<\/p>\n Now forensic scientists may have a new tool for their investigations: microbes. As explored in IPA\u2019s \u201cCloudy with a Chance of Microbes\u201d <\/a>humans emit a cloud combo that may serve as an identifying marker like DNA or a fingerprint.<\/p>\n The research by James F. Meadows and colleagues, Humans differ in their personal microbial cloud\u00a0<\/a>appeared in PeerJ<\/em> on Sept 22, 2015. \u201cOne of the most surprising results from the first experiment<\/em>,\u201d wrote the authors<\/a>,\u201d was the extent to which the three different occupants were easily discernible from one another, both from a microbial community perspective and also when considering individual bacterial\u2026<\/em>\u201d<\/p>\n Microbes also transfer to surfaces like doorknobs, cell phones and guns, as anyone who ever caught a cold can attest.<\/p>\n Outdoor air and pets contribute to surface microbes in a home but most are from humans. Visitors rapidly colonize the residence with their microbes when they arrive and deplete the picture within days after leaving.<\/p>\nThe question is: how reliable is microbe matching?<\/h4>\n
