Article Summaries:

  • The National Institute of Standards and Technology (NIST) has issued a new forensic DNA reference material, RM 8043, designed to aid crime laboratories in testing and training for complex evidence. The kit contains eight vials of DNA from anonymous donors, including high‑quality samples, mixtures of up to three individuals, and two vials of UV‑degraded DNA. Each vial holds roughly 900 ng of DNA, far more than the 0.5-1 ng typically required, allowing repeated use. Accompanied by a data sheet with the donors’ genetic profiles, the material lets labs validate equipment, software, and analytical methods against “ground truth” data. NIST distributed the samples to about 100 labs for preliminary testing before the December release.
