A new CSI tool could pinpoint when fingerprints were left behind
The crime scene investigators on TV's popular CSI: Crime Scene Investigation series seem able to solve any mystery thanks to a little science and a lot of artistic license. But now there is a real-life technique that could outperform even fictional sleuths' crime-busting tools. Scientists report a way to tell how old fingerprints are. This could help investigators determine which sets are relevant and which ones were left long ago.
Personal microbiomes shown to contain unique 'fingerprints'
A new study shows that the microbial communities we carry in and on our bodies known as the human microbiome have the potential to uniquely identify individuals, much like a fingerprint. Scientists demonstrated that personal microbiomes contain enough distinguishing features to identify an individual over time from among a research study population of hundreds of people. The study is the first to show that identifying people from microbiome data is feasible.
Caught by a hair: Quick, new identification of hair may help crime fighters
Crime fighters could have a new tool at their disposal. Researchers have developed a cutting-edge technique to identify human hair. Their test is quicker than DNA analysis techniques currently used by law enforcement. Early sample testing produced a 100 percent success rate. Blood samples are often used to identify gender and ethnicity, but blood can deteriorate quickly and can easily be contaminated. Hair, on the other hand, is very stable. Elements in hair originate from sweat secretions that alter with diet, ethnicity, gender, the environment and working conditions.
