Module Sixteen: Lab Project
Five New Forensic Technologies

Eye reflections used as an identification tool?

New advances in forensics have proven that the human eye can be magnified so greatly that the reflections in the eye are able to be seen and identified. With this technology, scientists are able to see the suspect’s location and surroundings, along with any people or objects close to the suspect’s eye.

In order for this technology to be effective, a close up picture of the eye is not necessarily needed. Photographs are able to be taken of the suspects face from an average ways away, and still the corneas reflection is able to be viewed –thanks to the advances in microscopic and digital technologies.

LABRADOR stands for Lightweight Analyzer for Buried Remains and Decomposition Odor
Recognition system.
This technology is used to sniff out dead bodies. The LABRADOR is a hand-held system, and looks
similar to a weed-eater or a metal detector. The system is made up of many different parts, but
the most important one seems to be the box that is capable of identifying the smells that come
from a decaying human body.

Now, you may be thinking
“Why would scientists lug around this large piece of metal when they could just locate bodies using trained dogs?”
This technology gives results very similar to using trained dogs to track down the bodies, but is often used alongside the dogs instead of by itself. The trained dogs are able to sniff out the body from a larger amount away, while the LABRADOR is used in a more concentrated area to detect certain chemicals, which could also be used to determine the time of death since the human body emits different chemicals the longer that it has been deceased!

Genetic testing shows that our DNA is not as unique as we may think

New technologies and recent studies show that some individuals DNA does not completely belong to them. One of the scientists preforming these studies is Dr. Urban, a genetic scientist at Stanford University. According to research, some people have genomes within their DNA that came from other individuals.

So far, the only way that this is capable happening is during pregnancies. For example, twins may share genomes of DNA, along with blood cells, since they were grown in the womb together. These twins may also have genomes of their mothers unique DNA. It is possible that each child receives copies of its mothers DNA while in the womb.

In a day and age where everyone is almost constantly engrossed in their hand-held devices, forensic science has caught up, creating their own on-the-go forensics lab.

The Mobile Forensics is able to be used on smartphones, laptops and other types of electronics. This technology allows forensic scientists to take many of the tools and information that they will need during an investigation with them in the palm of their hands. This technology is able to access DNA analysis, facial recognition and portable drug identification. Also included in this technology is the ability to perform fingerprint drug testing.

ADVANCES IN GENETIC TESTING
FORENSICS ON THE GO!
New Computer Software Detects Fake Pictures

A new software is aiding the field of digital and photo forensics. The software is able to detect fake or edited pictures by analyzing the pixels within the photos. This technology could prove useful for cases dealing with cyber crimes.

The software is able to tell whether or not a separate
software was used on the original photo in order to edit
it (such as Photoshop).
