SigSci Scientists Co-author Study Published in “Forensic Science International: Genetics”

An Algorithm for Random Match Probability Calculation from Peptide Sequences Abstract: For the past three decades, forensic genetic investigations have focused on elucidating DNA signatures. While DNA has a number of desirable properties (e.g., presence in most biological materials, an amenable chemistry for analysis and well-developed statistics), DNA also has limitations.... MORE

DNA-Touch™ – Synthetic Fingermarks for Genomics Research

Variability in the amount of DNA deposited by individuals when touching a surface poses a significant hurdle to the evaluation of forensic analysis methods for touch samples. No two human latent fingerprint samples are the same due to the "shedder" status of different individuals as well as other factors including... MORE

SigSciPT: Suspicious White Powder Incidents Present New Risks

Fentanyl and its analogues present identification challenges for first responders Fentanyl and its analogues are more frequently making their way into common street drugs, adding a new dimension of danger to even incidental exposure to these substances. Fentanyls are increasingly being added to heroin and other illicit drugs because they... MORE
