There are some things that make your spine tingle that are exciting and good for you, but more often than not, if you experience a tingling in your back it is a sign of something bad. Back injuries are probably not something you immediately associate with forensics and laboratory work. However, there are plenty of ways to injure your back if you perform forensic field work or work in a laboratory.
From a forensic perspective, the Recycle Bin can be a “gold mine” for gathering probative evidence which can be extremely valuable for investigative purposes. There are many forensic tools available that are designed to recover deleted files from the Recycle Bin. Depending upon the length of time a file has been deleted, forensic tools can recover the entire file or parts of the file (if it was partially overwritten).
When it comes to forensic science, gas chromatography/mass spectrometry (GC/MS) is a powerful technique in any analysts’ toolbox. Due to its simplicity, accuracy, sensitivity and versatility, GC/MS is often called the gold standard of analytical methodologies for many forensic tests.
So what is a LIMS and a QMS? If I run a laboratory, do I need one of these or do I need both? In a laboratory setting, there is a plethora of data that needs to be tracked. Very important work is being completed on a day-to-day basis and a system needs to be able to help a laboratory efficiently capture that sample analytical testing data.
This particular case concerned blood-alcohol analysis via gas chromatography (GC), the preeminent analytical tool commonly used in the forensic science arena for the determination of alcohol in blood samples. The focus was on the quantitative assessment of the data stemming from the analysis, which involved direct injection of appropriately prepared liquid samples into the gas chromatograph.
Progressive forensic practitioners are always searching for ways to increase their accuracy and efficiency in the field, while also improving their presentations of complex evidence.
Although the new software was not used in any cases involving the suspended employees, the agency said it is providing pertinent information to ensure legal obligations are upheld in cases involving the suspended employees.
Tetrahydrocannabinol (THC), is the main psychoactive constituent of cannabis.

In the aftermath of the Boston Marathon terrorist attack, pathologists had to improvise to preserve forensic evidence in the midst of life-saving surgeries and amputations. Some of the most vital clues were embedded in the tissue of those fighting to stay alive.
The London Metropolitan Police released CCTV footage of the robbers this week, calling on the public to help in the investigation, and giving detailed information about forensic evidence found at the scene.
Today’s investigative teams are buried under a mountain of digital data that comes from an increasing number and variety of sources. As the quantity of potential evidence continues to grow, some might yearn for a simpler time before the latest advances in technology; especially since criminals have become quite efficient at using these tools to hide their crimes and evade detection and prosecution.
According to a July 2000 article by FBI Unit Chief Douglas W. Deedrick—published only months after the FBI stopped using the flawed technique—the agency admitted that the technique was not only flawed, but needed careful handling when used as evidence in criminal cases.
THE F.B.I. stunned the legal community on Monday with its acknowledgment that testimony by its forensic scientists about hair identification was scientifically indefensible in nearly every one of more than 250 cases reviewed. But the conclusion should come as no surprise to scientists.
The Department of Justice along with the FBI have identified 2,500 cases for review after finding that experts on its microscopic hair comparison unit overstated evidence concerning pattern-based forensic techniques in 95 percent of the 268 cases reviewed so far.
Scientists will compare any DNA found on the bed sheet to future tests of blood samples from verified Lincoln artifacts, which would determine, once and for all, if the bed sheet was present at one of the most seminal moments in American history.
