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.

On CSI, NCIS and other popular television shows, mass spectrometers rapidly analyze biological samples and spit out definitive results of complex analyses. But in real life, mass spectrometry findings are less straightforward and slower paced. Analytical chemist Nicholas Manicke has received a grant from the NIJ to improve the speed and accuracy of mass spectrometry for detecting drugs and poisons in blood samples.
Researchers used information collected from hundreds of skin swabs to produce three-dimensional maps of molecular and microbial variations across the body. These maps provide a baseline for future studies of the interplay between the molecules that make up our skin, the microbes that live on us, our personal hygiene routines and other environmental factors.

Bloodshed was part of life in Iguala, Mexico before local police allegedly disappeared 43 college students in September, and it remains so now. Despite federal efforts to wrest control, the 600 federal officers and 1,000 soldiers sent in five months ago to replace the city's police force have had no effects on the killings and kidnappings. The violence continues because Iguala's most lucrative business still thrives: the opium trade.

Alison Davidson is a kind of olfactory Sherlock. A quiet but crisp scientist who runs the forensics lab at the University of Staffordshire, she is working on a form of analysis that in the near future could allow police to gather odor evidence from, say, a coat left at the scene of the crime to build a profile of a suspect.
Authorities found marijuana, a nearly empty bottle of whiskey and anti-psychotic medication while searching the home of the former Marine charged with killing "American Sniper" author Chris Kyle and his friend, a Texas Ranger testified recently.

An Ohio man who sold fake urine and other products meant to help people pass workplace drug tests has pleaded guilty before a federal judge in Pennsylvania.
Mexican farmers are feeding a growing addiction in the U.S., where heroin use has spread from back alleys to the cul-de-sacs of suburbia.
