While carbon monoxide is generally considered the major lethal agent in smoke inhalation, a case study of an elderly Romanian gentlemen highlights the contribution of another less-known killer – hydrogen cyanide. Continue reading A new indicator of fire-related fatalities: hydrogen cyanide
Pelleti’s team at the University of Bologna developed a straightforward way to distinguish fly artifacts from real bloodstains using electron microscopy. Continue reading Fly Be-Gone: Discerning Bloodstains from Fly Stains with Electron Microscopy
Scientists discover that blowfly eggs may develop earlier than previously thought, calling into question the accuracy of time of death calculations from forensic entomologists. Continue reading Premature blowfly egg development leads to inaccurate time since death estimations
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
Researchers from Florida International University investigate if they can use SERS to rapidly detect synthetic cannabinoids in oral fluid. Continue reading Can metal nanoparticles and portable lasers detect synthetic cannabinoids in saliva?
To make invisible fingermarks, well, visible, forensic scientists use chemical compounds like superglue. But what if instead we could make them glow – using quantum dot technology? Continue reading Quantum dots shine new light on latent fingermarks
Researchers from Florida International University develop a method that can help analyze new drugs. Continue reading A New Method for Identifying Novel Psychoactive Substances
Bed bugs invade homes to engorge themselves on our blood. Can forensic scientists crack open these pesky critters and trace back to who they recently feasted upon? Continue reading Fact or Fiction: Extracting human DNA evidence from bed bugs
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
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?
