History Channel on the Early Implementation of DNA in Forensic Science. From its beginnings to CODIS. The Timothy Spencer Case, DNA Data Banks, Paul B. Ferrara, Innocence Project, and Early Backlogs, ect.
In this episode of SciShow, we’re going to investigate a murder. But first, we’re going to have to learn all about forensics, the use of science in criminal law -- and the real-life version is a little different from what you might see on TV.

Please visit our website at http://www.nfstc.org DNA is life's blueprint, a molecule that encodes genetic instructions used in the development of all known living organisms and viruses. But how is DNA used in the field of forensic science? NFSTC presents "DNA Analysis," a brief explanation of what DNA is, how it functions, and the multi-step Forensic DNA Analysis process.
Explaining DNA: how forensic investigators use DNA fingerprinting at a crime scene to identify the culprit. Find this and more KS3 animations on Activate 3 Kerboodle: Lessons, Resources and Assessment. Find out more about Activate at www.oxfordsecondary.co.uk/activate.
Before DNA testing, prosecutors relied on less sophisticated forensic techniques, including microscopic hair analysis, to put criminals behind bars. But how reliable was hair analysis?

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.
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. Dan is a professor in the Department of Biological Sciences at Wright State University where he has been a faculty member since 1993 and where he currently serves as the President of the Faculty. He graduated with a Bachelor’s degree for a double major in Biology and Chemistry from John Carroll University, and a Ph.D. in Bioche...
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...
Five cases solved by DNA evidence.
In forensics, sometimes samples are so degraded that traditional DNA extractions and methods may not work. Jacques and Irene with Mitch Holland explain how high-throughput sequencing is helping us realize the power of mitochondrial DNA heteroplasmy — ultimately leading to the solving of more crimes. Used to identify the remains of Tsar Nicholas Romanov II, you’ll see how MtDNA heteroplasmy can now be used to routinely, detect, resolve and report using NGS technology, benefitting the forensics community for years to come.

How do we tell people apart by using their DNA? From murder investigations to paternity testing, DNA fingerprinting is an essential tool in the modern world. But how is it carried out? Find out in the latest Naked Science Scrapbook!More videos and podcasts from http://www.thenakedscientists.com
Get the most out of your casework samples with minimal effort. The Investigator Quality Sensor enables you to make confident decisions about how to proceed with your samples after PCR. Is the profile ready for further analysis? Do you need to repeat the PCR? Would diluting the sample help you get a better profile? This short video shows you how easy it is to answer these questions, thanks to the Investigator Quality Sensor. If you insist on quality, insist on Quality Sensor!
