In the 1800s, Wilhelm Kühne created an image of a window from the eyes of a rabbit. Was this technology applicable to humans? Hosted by: Michael Aranda

Just like any other science, forensic science is based on principles and laws. These are the law of individuality, the law of progressive change, Locard's law of exchange, the law of probability, the principle of comparison, and the...

Documenting the crime scene thoroughly is very important, as once the scene is cleaned up, it is impossible to go back and check some detail that may be relevant to the case later. There are several methods of documenting the crime...

We just looked at note taking and sketching as two ways of documenting the crime scene. Now let's look at two more, photography and videography. What is the correct protocol for taking photos of all the evidence at the crime scene? Let's...

After properly documenting evidence, it's time to collect it for further analysis. How is this done? There is very strict protocol for keeping all evidence separate, and properly recording precisely where it came from, so let's get some...

In this series we are going to learn all about crime scene investigation. But we must first understand precisely what crimes are. What does it mean to say that someone has committed a crime? What are the types of crime that can be...

Are you obsessed with crime-based entertainment like CSI and Sherlock? How accurately is crime scene investigation depicted on such shows? What exactly is forensic science, and what are the scientific principles it utilizes? If you want...

In this video, we will talk about the evolution of DNA analysis in forensic science. Discover how this groundbreaking technique emerged, revolutionizing criminal investigations. From its humble beginnings to pivotal cases that shaped its...

Forensic scientists use different methods to identify a body at a crime scene. This subfield of forensic science is called body identification.

Once a person dies, their body begins a process of decay. This process can be seen through certain external changes which are called post mortem signs of death. There are 4 postmortem signs of death - pallor mortis, algor mortis, rigor...

In this video, we explore the incredible world of forensic science and how DNA technology is helping to solve some of the most complex crimes. From the basics of how DNA works, to the cutting-edge techniques used to extract, analyze,...

From radio waves to gamma rays, the electromagnetic spectrum is useful in different ways. How does this radiation differ and how can they be used? Physics - Waves - Learning Points. Electromagnetic radiation exists along a continuous...

DNA profiling can match individuals to a crime scene using only a few cells. A brief history of DNA profiling and the breakthroughs that have made this possible. Biology - Cells And DNA - Learning Points. DNA is described as a...

Dive into a hands-on forensic training session with four future detectives in Ecully near Lyon, exploring the precision of fingerprint analysis, DNA extraction, and the unique method of odorology. Discover how modern techniques rapidly...

In an age where technology is intertwined with daily life, learn how easily your devices can be hacked and used for spying. From mobile phones to computers, discover the methods used by modern spies to infiltrate your privacy. Follow...

“How to Roll Fingerprints” will demonstrate to students the correct way to roll fingerprints.

Once a person dies, their body begins a process of decay. This process can be seen through certain external changes which are called post mortem signs of death. There are 4 postmortem signs of death - pallor mortis, algor mortis, rigor...

What are DNA Mixtures? And why are they sometimes so difficult to interpret? Sheila Willis, a guest researcher at the National Institute of Standards and Technology (NIST) and the former director general of Forensic Science Ireland,...

NIST Fellow and DNA expert John Butler describes his work in DNA forensic science, how NIST standards enable accurate DNA measurements to be made, how NIST methods helped ID victims of 9/11, how he got interested in forensics, and how...

NIST researchers demonstrate techniques for screening illegal drugs for the synthetic opioids like fentanyl that are causing a spike in overdose deaths. More
