  • Inside the Crime Lab: Forensic Biology DNA Unit

    The Forensic Biology Unit of the Denver Police Crime Lab examines evidence recovered from crime scenes for potential biological matter. They identify biological fluids, then take swabs or cuttings from the evidence and process them for analysis. Cases that test positive in the Forensic Biology Unit go on to forensic DNA analysis. The goal of the DNA Unit is to develop DNA profiles from items of evidence and compare them to known DNA profiles from crime investigations.

  • Exploring bias in forensic DNA profiling | Dan Krane | TEDxDayton

    This talk was given at a local TEDx event, produced independently of the TED Conferences. The science of DNA profiling is sound, but much of what passes as DNA profiling is not scientific. Many testing labs resist interpreting evidence samples without having knowledge of a suspect's reference DNA profile. Blind interpretation of test results is possible and would greatly increase the reliability of the statistical weights given to DNA profile matches in some cases.

  • Using DNA to Identify People

    This lesson focuses on the molecular biology technique of DNA fingerprinting: what it is, how it works, and how the data from these experiments are used for paternity testing and forensics? DNA can be used to tell people apart because humans differ from each other based on either their DNA sequences or the lengths of repeated regions of DNA. Length differences are typically used in forensics and paternity testing. The technique of gel electrophoresis separates DNA by size, thus allowing people to be identified based on analyzing the lengths of their DNA. We discuss how gel electrophoresis works, and lab footage is shown of this technique being performed in real time. Students then analyze results from these experiments and work on case examples using DNA to match babies to parents and crim...

Here are 14 of the most amazing science techniques and technology that lets us carbon date and even do age progression! Subscribe to Talltanic http://goo.gl/wgfvrr 7. Ballistics This side of science involves everything that has to do with the flight, behavior, effects, and launching of projectiles such as gravity bombs and rockets but when most people say ballistics they’re referring to bullets. Ballistics is broken down into four main categories. These are internal ballistics, transitional ballistics, external ballistics, and terminal ballistics. In the field of forensics, ballistics is used to analyze the bullet itself and its impact to see if the information found can be used in a court of law. 6. DNA Sequencer This scientific device is used to help figure out the order in which the four bases of DNA are arranged in in a specific sample of DNA. For those of you that don’t remember the four bases from high school biology, they are guanine, cytosine, adenine, and thymine. Crime lab technicians and forensic scientists alike use a DNA sequencer when their DNA sample is too deteriorated in order to get a special DNA pattern that can aid in identifying the criminal. This special DNA pattern is called a “read”. 5. Hair Analysis One of the key elements that usually ends up putting criminals in jail is something that they’ve managed to completely overlook. That one small detail that plays a crucial part in their conviction is DNA. DNA evidence can range from bodily fluids such as blood or seminal fluids and fingerprints. However, clothing fibers and hair are just as important. The average person loses around 60-100 hairs per day and there’s no way you could keep track of where they fall. This works in favor of the forensics team. It was recently announced that human hair protein could potentially replace DNA as a key tool in forensics because of special markers that could allow the hair to distinguish an individual from a large group of people, say one million. 4. Polymerase Chain Reaction Abbreviated as PCR, the polymerase chain reaction technique was created by Kary Mullis back in the 1980’s and has gone on to be used in many different applications such as molecular biology and forensic science. Basically what PCR does is that it takes a single copy of DNA and replicates it around thousands to millions of times enough to where forensic scientists are able to successfully test it to match the DNA evidence of the potential suspect. This was a major breakthrough for cases that didn’t have enough DNA evidence to solve their cases and allowed these cases to be solved decades after they were committed. 3. Forensic Facial Reconstruction The first time a facial reconstruction was done was back in 1883 and then again in 1895. This technique combines several different fieldsー anthropology, anatomy, osteology, forensic science, and artistry in order to help solve the identity of someone that isn’t known by using their skeletal remains. This technique is quite controversial as it does prove to be somewhat problematic. Facial tissue thickness is the main issue that plagues this method but also the methodological standardization of the individual’s facial features. Even though it’s not completely accurate it has proven useful in identifying victims and putting away perpetrators behind bars. 2. Fingerprint Analysis There are considered to be hundreds of techniques in order to detect fingerprints, however, most of them are only for academic interest and there’s really only roughly 20 methods that are extremely accurate and used in fingerprint labs all over the world. This is because fingerprints are classified into three groups: three-dimensional plastic prints, patent prints, and latent prints that each vary depending on the type of surface the print was discovered on. The most common method used to convict criminals has been dusting where forensic scientists use black granular powder to locate the prints and then lift them with an adhesive tape, though the powder does have the potential to contaminate the evidence. 1. Luminol Spray Perhaps one of, if not, the most important techniques that forensic scientists have under their belt is luminol. This chemical can be traced back to 1928 when a German Chemist named H.O. Albrecht discovered that blood is able to make this chemical glow. See, the reason that this is possible is thanks to the iron that is found in the hemoglobin of blood and acts as a catalyst that sets off the chemical reaction. The chemical will then give off a blue glow but in order to be visible the room has to be dark enough and luminol only lasts up to 30 seconds so forensic photographers have to work very fast.

Limits of Traces - The Phantom of Heilbronn http://www.sipr.ac.uk/downloads/Phantom_of_Heilbronn.pdf "The 'Phantom of Heilbronn' was one of Germany's most-wanted criminals. As the traces were connected to a female offender, 'she' was suspected having committed a series of different crimes (murders, break-ins, theft) across Germany over more than 15 years. Tests showed her DNA at 40 different crime scenes. The only connection between the crimes was this DNA trace." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

This lesson focuses on the molecular biology technique of DNA fingerprinting: what it is, how it works, and how the data from these experiments are used for paternity testing and forensics? DNA can be used to tell people apart because humans differ from each other based on either their DNA sequences or the lengths of repeated regions of DNA. Length differences are typically used in forensics and paternity testing. The technique of gel electrophoresis separates DNA by size, thus allowing people to be identified based on analyzing the lengths of their DNA. We discuss how gel electrophoresis works, and lab footage is shown of this technique being performed in real time. Students then analyze results from these experiments and work on case examples using DNA to match babies to parents and crime scene evidence to suspects. In terms of prerequisite knowledge, it would be ideal if students already have learned that DNA is the genetic material, and that DNA is made up of As, Ts, Gs, and Cs. It also would help if students already know that each human has two versions of every piece of DNA in their genome, one from mom and one from dad. Necessary supplies for this lesson include only paper and writing utensils, and the ability to print out or display the provided handouts. The lesson will take about one class period, with roughly 30 minutes of footage and 30 minutes of activities. At the end of the lesson, an optional video tour of the Cambridge Police Department’s Identification Lab is provided, giving students an opportunity to see the equipment used in crime labs to isolate both real fingerprints and DNA for DNA fingerprint analysis, from evidence found at crime scenes. Watch optional video (http://blossoms.mit.edu/videos/files/english/visit_police_identification_lab_english_flash): Visit to Police Identification Lab in Cambridge, MA to see how DNA is extracted from evidence at crime scenes.

When all venues of police investigations fall short and no clues left or evidence nor whiteness to testify to the ordeal done by the perpetrator, sometimes there would be no concrete fact to apprehend such criminal. However there would be only one single solution as alternative and this is "Forensic DNA Analysis", the technique that can draw biological evidence from tiniest stroke or simple touch of doer at crime scene......
