Transfer DNA: An updated and Unbiased Term for Touch/Trace DNA
Authored by: Angela Williamson, Abigail Bathrick, Mike Cariola Forensic scientists have long recognized the phenomenon and probative value of DNA transferred to people or objects through direct or indirect contact1. Various terms have been utilized by the forensic community over the past decades to include Touch, Trace, and Wearer DNA. However, the need for standardized […]
Difficult Does Not Mean Impossible
Difficult evidence will always require forensic expertise. The process surrounding it does not have to be equally difficult. Better methods can give challenging samples another opportunity to provide information, accessible collection tools can help clients use those methods more readily, and better laboratory systems can protect analysts’ time for the decisions that require their judgment. […]
LOAD. START. WALK AWAY. Experience What’s Next in Forensic DNA Sample Prep at ISHI 2026
There’s automated forensic DNA extraction. And then there’s true walk-away automation. At ISHI 2026, Thermo Fisher Scientific will unveil the new Applied Biosystems™ PrepStudio™ Express DNA Extraction System—a benchtop system designed to bring true walk-away automation to forensic DNA sample preparation. Designed to fully automate lysis and DNA purification for forensic casework and sexual assault […]
STR Nomenclature: Building a Common Language for Forensic Genomics
As next-generation sequencing (NGS) becomes more commonplace in forensic genetics, one of the critical questions facing NGS-equipped laboratories is: how can scientists consistently interpret, share and compare short tandem repeats (STR) sequencing data? At the center of this challenge is STR nomenclature – the system used to describe STR alleles. Insights from experts such as […]
Forensic MPS. Redefined.
Massively parallel sequencing (MPS) has long promised to transform forensic DNA analysis. The ability to interrogate more loci, generate richer allele data, and multiplex dozens of samples in a single run represents a compelling leap forward from capillary electrophoresis (CE). Yet adoption in routine casework has remained limited—held back by complex, multi-step library preparation workflows […]
Defensibility by Design: Embedding Auditability into Forensic Genome Sequencing
Othram has developed a new method to embed proof of proper handling and authenticity directly into the DNA evidence itself, adding a molecular layer of verification that complements traditional chain-of-custody records. Forensic DNA testing has always required results that are defensible. From its earliest use in criminal investigations and human identification, forensic genetics has operated […]
Novel Promega Enzyme Tackles Biggest Challenge in DNA Forensics
Sponsored by Promega On September 25, 2024, Promega Research Scientist David Mokry addressed a full audience at the International Symposium on Human Identification. The event brings together people from the forensic DNA industry – criminalists, analysts, lab directors and more – eager to learn about advancements in the field. Over the next 20 minutes, David […]
From Bone to Identity: DNA Solutions’ Success in Human Remains Testing
Sponsored by DNA Solutions Recovering DNA from human remains is one of the most challenging areas in forensic science. Bone samples are often decades old with substantial DNA degradation and affected by additional factors such as fire, burial, or environmental deterioration, which increase degradation and inhibit PCR amplification. These factors present significant barriers to the […]
