Question

What changes has DNA made to forensic science?

Answer 1

Answer: Over the years, DNA has become one of forensic science's most powerful tools, helping to identify suspects and victims, convict the guilty and exonerate the innocent. DNA science and technology have grown so advanced that a mere touch can link someone to a crime scene. DNA can be used to identify criminals with incredible accuracy when biological evidence exists, and DNA can be used to clear suspects and exonerate persons mistakenly accused or convicted of crimes. ... In addition, these labs may be ill-equipped to handle the increasing influx of DNA samples and evidence. Hope this helps

Modern Breakthroughs

Now that we’ve seen the history, here are a few modern breakthroughs in forensic technology and analysis, applicable in a variety of fields within forensics.

LABRADOR. The cleverly named LABRADOR (Light-weight Analyzer for Buried Remains and Decomposition Odor Recognition) is a device used to “sniff” out various chemicals that are released by decaying bodies. Highly useful with missing persons reports.Chemical Forensics. Similarly, a chemist at the Pacific Northwest National Laboratory is devising a forensic technique that can detect the source of impurities within chemicals, that could lead to finding criminals in a terrorist attack.Blood Spatter Improvements. Physicists at Washington State University have recently developed a mathematical way to analyze blood spatter and plotting how blood droplets will fall from a ceiling or wall.Forensic Ballistics. Numerous advancements in ballistics technology have been made using 3D imaging. Analysis of these projections can help determine where a weapon was fired based on shells and cartridges.Cyber Hacking. With recent events such as the Sony hacks and the attacks at Charlie Hebdo in Paris, digital forensic experts are using the latest in computer technology to track down the perpetrators of these crimes.Alternative Light in Forensic Nursing. Forensic nursing is a very specific concentration of forensics. Use of alternative light photography can help nurses care for patients while maintaining the integrity of evidence as well.
