Glass particles are notoriously difficult to study since they are small and nearly invisible. A Dutch research group is using glow-in-the-dark sand to study glass particle transfer. Continue reading Developing a New Visual Model for Glass Particle Transfer
CSI examiners can determine many things with gunshot residue – but not whether there was a suppressor on the weapon. Now, scientists from Italy have shown that a subtle influence in the metal properties of GSR can indicate the presence of a silencer. Continue reading New method reveals if a silencer was used in a shooting
DNA is notoriously difficult to extract from forensic soil samples. Researchers investigate if adding skim milk can increase the recovery of DNA evidence. Continue reading Milk It for All It’s Worth: How Skim Milk Increases DNA Yield from Soil Samples
Counterfeit medication poses a series threat to patient safety and public health. How can pharmaceutical companies guarantee their product is making it into patient hands? New work shows how companies can subtly mark their true products with edible silk “tags” inscribed with an invisible fluorescent code. Continue reading New research combats counterfeit medication with edible silk tags
Researchers from the University of Central Florida determine a quicker way to use paint chip analysis for the investigation of vehicular crimes. Continue reading Faster Ways Of Making Paint Chips Tell It All
The close, physical contact during a violent crime leads to transfer of materials from victims to perpetrators (and vice versa) such as DNA. Researchers at the University of Central Florida recently showed that two unusual types of physical evidence, glitter and shimmer, have the potential to link individuals as well. Continue reading Body glitter and shimmer can aid sexual assault investigation
Fire destroys buildings and leaves only ash and rumble in its wake. Arsonists believe that their fiery M.O. protects them from the threat of biological evidence. However, researchers in Australia reveal buried bloodstains from dense, sooty remains. Continue reading Photographing blood under layers of soot with infrared cameras
There are many ways to separate a mixture of powder drugs – but magnetic levitation? Continue reading Using the power of magnets to separate drug powders
