Forensic science has rapidly grown with the advancement in technology.
Fremont, CA: With technology infiltrating every part of our lives, it's no surprise that solving crimes has advanced to the point of being futuristic. Actual forensic technology, from retinal scanning to trace evidence chemistry, are so advanced in helping to solve crimes that they appear like something out of a science-fiction novel.
This sector is one of the fastest-growing in the United States, because to all of the forensic technology. The growing demand for forensic science technicians is one way to quantify this. Here is a list of technologies that impact forensic science.
DNA Phenotyping: While DNA from a crime scene can be used to match a suspect by comparing samples, DNA can also be used to figure out what a suspect looks like physically. The external appearance of DNA is coded by 23 chromosomes. Forensic scientists can sequence a DNA sample and give police information on the suspect's distinguishing characteristics, such as hair, eye, and skin color. Age and biological background can also be predicted using newer approaches.
Forensic Palynology: Forensic palynology is a new area of study for forensic scientists. Palynology is the study of pollen, spores, grains, and seeds, which can be used in forensics to locate a person. Pollen and spores are extremely small and can go unnoticed on skin and clothing. Scientists have yet to develop tools to collect, compare, and use these trace materials as evidence.
Social Network Forensics: Over 3.6 billion individuals use social media, with that number expected to rise to 4.5 billion by 2025. When social media initially became popular, detectives and forensic scientists had less data to work with. The amount of social media data for a given topic might now be overwhelming. Scientists have recently created methods for assessing information collected from social networks to aid in the evaluation of this data. To be accepted in court, automated data analysis must be based on models that are repeatable, explainable, and testable.
Biosensors: Fingerprints collected at a crime scene, like DNA, can be compared to identify a suspect. Fingerprints, on the other hand, aren't always clear or readable. To identify a culprit, forensic experts can now utilize biosensors to examine minute quantities of human fluids contained in fingerprints. Age, prescriptions, gender, and lifestyle are examples of data that can be identified. Other physiological fluids found at a crime scene can also be tested with biosensors.
