This article reviews the examination of animal hairs and their role in the forensic arena. The forensic examination of animal hair is a well-established discipline and has been so for two centuries. Examination is largely based on microscopy, which may enable the hair analyst to identify a hair as animal in origin, to characterize the hair to a particular species, and to conduct comparative exa...

DNA profiling (also called DNA testing, DNA typing, or genetic fingerprinting) is a technique employed by forensic scientists to assist in the identification of individuals by their respective DNA profiles. DNA profiles are encrypted sets of numbers that reflect a person's DNA makeup, which can also be used as the person's identifier. DNA profiling should not be confused with full genome sequen...

Bacterial content may be helpful in differentiating forensic soil samples; however, the effectiveness of bacterial profiling depends on several factors, including uniqueness among different habitat types, the level of heterogeneity within a habitat, and changes in bacterial communities over time. To examine these, soils from five diverse habitats were tested over a 1 year period using terminal ...

The ground-breaking report on forensic science by the National Academy of Sciences— Strengthening Forensic Science in the United States: A Path Forward—raised numerous issues. One dominant theme that runs throughout the Report is the failure of some forensic science disciplines to comport with fundamental scientific principles—in particular, to support claims with empirical research. This essay...

This paper investigates the application of novelty detection techniques to the problem of drug profiling in forensic science. Numerous one-class classifiers are tried out, from the simple k-means to the more elaborate Support Vector Data Description algorithm. The target application is the classification of illicit drugs samples as part of an existing trafficking network or as a new cluster. A ...

former NSW policeman, Harry Blackburn, was cleared of multiple sex charges on the 11 October 1989, and a Victorian was convicted of rape a week earlier. In both cases DNA (deoxyribonucleic acid) profiling was used. DNA profiling illustrates the most powerful concept in forensic science, the power to eliminate a suspect. DNA profiling has a very high discrimination power and is therefore very po...

Soil has the potential to be valuable forensic evidence linking a person or item to a crime scene; however, there is no established soil individualization technique. In this study, the utility of soil bacterial profiling via next-generation sequencing of the 16S rRNA gene was examined for associating soils with their place of origin. Soil samples were collected from ten diverse and nine similar...

This review describes the social and ethical responses to the history of innovations in forensic genetics and their application to criminal investigations. Following an outline of the three recurrent social perspectives that have informed these responses (crime management, due process, and genetic surveillance), it goes on to introduce the repertoire of ethical considerations by describing a se...

This review article focuses on mass disaster situations that may arise from natural or manmade circumstances and the significant role of forensic dental personnel in human identification following such occurrences. The various forensic dental modalities of identification that include matching techniques, postmortem profiling, genetic fingerprinting, dental fossil assessment and dental biometric...

Capillary electrokinetic separation techniques offer high efficiency and peak capacity, and can be very useful for the analysis of samples containing a large variety of (unknown) compounds. Such samples are frequently met in impurity profiling of drugs (detection of potential impurities in a pharmaceutical substance or product) and in general sample profiling (determination of differences or si...
