The 2024 NIST Generative AI (GenAI) Pilot Study focuses on evaluating text-to-text (T2T) generation and discrimination tasks to assess the capabilities and limitations of generative AI models and AI detectors. The study aims to measure the effectiveness of
Drug-checking programs use point-of-need testing (e.g., test strips) and laboratory-based analysis to rapidly identify emerging drug threats, but each has limitations. Test strips are quick but compound or class specific, whereas laboratory testing can
The Bullet Black Box Working Group (BulletBB-WG) was convened to review the results of the NIST-Noblis Bullet Black Box Study, and assess the implications of that study on casework. This report includes the recommendations of the BulletBB-WG on how to
STRBase (strbase.nist.gov) was launched in late 1997 to collect and organize information in one location about Short Tandem Repeats (STR), the new emerging forensic marker type at the time. Over the next twenty-plus years, data related to STR markers was
Forensic and commercial laboratories rely on well-characterized analytical methods to accurately determine total tetrahydrocannabinol (total THC), which is the sum of decarboxylated tetrahydrocannabinolic acid (THCA) and delta-9-tetrahydrocannabinol (Δ9
Officers of the Court including judges and attorneys can benefit from receiving information from neutral sources to inform their understanding of foundational scientific and forensic science principles. Inspired by a request from Congress and a National
