Freckle On: Predicting Freckles from DNA
Biotechnologists take a step forward in forensic DNA phenotyping with the prediction of freckles. Continue reading Freckle On: Predicting Freckles from DNA
The smallest RNAs identify the most important body fluids in forensics
Knowing whether a stain is semen or saliva helps investigators recreate crime scenes and solidify links between suspects and criminal acts. But degraded samples are difficult to analyze – could microRNAs be the solution? Continue reading The smallest RNAs identify the most important body fluids in forensics
How does dirt affect ignitable liquids?
Scientists from the National Center for Forensic Science and Indiana University document soil degradation of ignitable liquids, potentially allowing analysts to overcome this issue with real evidence. Continue reading How does dirt affect ignitable liquids?
Tying it all together: Lasso statistical analysis brings new power to fiber evidence
Fibers are a common type of forensic trace evidence and can be used to link a suspect, scene and victim. But the general presence and composition of fibers prevents the specificity that detectives and crime scenes techs crave. Could a new statistical analysis called Lasso increase the evidentiary value of fibers? Continue reading Tying it all together: Lasso statistical analysis brings new power to fiber evidence
What is the best method for collecting touch DNA on clothing?
PhD student Francesco Sessa and his colleagues at the University of Foggia, Italy have determined that adhesive tape is the best method for retrieving touch DNA left on clothing- even after only 2 seconds of contact. Continue reading What is the best method for collecting touch DNA on clothing?
Building a “Face” from DNA
Can geneticists reconstruct the physical characteristics of an individual’s face from their DNA? Continue reading Building a “Face” from DNA
Transitioning from color tests to electric currents for identifying cannabinoids
Researchers from the University of Ottawa develop a method that uses organic thin film transistors for the on-spot detection of THC and CBD. Continue reading Transitioning from color tests to electric currents for identifying cannabinoids
Back to the Future: Advances in DNA Analysis Using Massively Parallel Sequencing
Traditionally, capillary electrophoresis is used to observe and detect STRs for the analysis of DNA profiles. Biotechnologists research massively parallel sequencing of STRs to increase throughput generating sequences for DNA profiles faster and more efficiently. Continue reading Back to the Future: Advances in DNA Analysis Using Massively Parallel Sequencing
Can Raman spectroscopy protect us from nerve gas?
A team in Spain developed a rapid and accurate way to detect chemical warfare agents- in the air. Continue reading Can Raman spectroscopy protect us from nerve gas?
Fireworks provide insights to dangerous homemade explosives
Equipped with the knowledge of creating powerful explosives, criminals can now produce more devices. A group of researchers set out to establish a quick way to identify the manufacturers of these explosives. Continue reading Fireworks provide insights to dangerous homemade explosives
