DNA Sequencing to Save Endangered Species
Since the 1980’s, DNA evidence has been used in the criminal justice system to help convict violent offenders and, just as importantly, exonerate innocent individuals. An approach often used is DNA profiling, a technique where investigators compare the base pair order of DNA found at the crime scene to a suspect’s DNA. Now, another type of genetic analysis – DNA barcoding – is being used to combat illegal wildlife trading.

Fiber Evidence from Crime Scene Investigations
Criminal investigations have been used for centuries in an effort to fight crime. The techniques used have evolved over the years, and the field of forensic science can now solve more crimes than ever before. Modern forensics labs utilize cutting edge techniques such as DNA fingerprinting, forensic entomology, and trace chemical analysis. While these procedures use state-of-the-art technology, many crimes are still solved by using classical techniques to examine the physical evidence at a crime scene.
