NIST Invites Comments on Structure of Forensic Science Guidance Groups

The National Institute of Standards and Technology (NIST) is seeking input on the structure of guidance groups that would promote scientific validity and reliability in forensic science. NIST is inviting comments on the structure of the groups through a Notice of Inquiry published Sept. 27, 2013, in the Federal Register.

Muscles & Meth

An international team of scientists have identified potentially dangerous amounts of methamphetamine analog in the workout supplement Craze, a product widely sold across the U.S. and online. The study, published in Drug Testing and Analysis, was prompted by a spate of failed athletic drug tests. The results reveal the presence of methamphetamine analog N,α-DEPEA, which has not been safely tested for human consumption, in three samples.

DNA Products Receive Validation/Approval

Two companies announced earlier this month developments in their products' approval and/or validation by nationally recognized organizations.

Natural Enzymes Conquer Difficult Cleaning Challenges

Zymit Low-Foam is a synergistic dual-enzyme and detergent formula that specifically target and remove protein- and starch-based soils. The enzymes break down dirt, and the detergents gently wash it away. In some cases, Zymit Low-Foam will even deodorize. With a typical pH (neat) of 6.9 to 8.4, Zymit Low- Foam is almost as mild as ordinary water.

Raman Spectroscopy of Paints

This report describes a study intended to identify pigments in automotive and architectural paint samples and develop practical methods for pigment analysis and identification using raman spectroscopy.

Microfluidic Technique Recovers DNA for IDs

A team of researchers at the National Institute of Standards and Technology (NIST) and Applied Research Associates, Inc. (ARA, Alexandria, Va.) has demonstrated an improved microfluidic technique for recovering DNA from real-world, complex mixtures such as dirt. According to a recent paper*, their technique delivers DNA from these crude samples with much less effort and in less time than conventional techniques. It yields DNA concentrations that are optimal for human identification procedures and can potentially be miniaturized for use outside the laboratory.

Recovering Latent Fingerprints from Cadavers

IN A HOMICIDE CASE, the recovery of latent impressions from a body is just one more step that should be taken in the process of completing a thorough search. This article is directed at crime-scene technicians and the supervisors who support and direct evidence-recovery operations both in the field and in the controlled settings of the medical examiner’s office or the morgue under the coroner’s direction.
