An Investigation of Downstream Processing Methods for Challenging Skeletal Samples

Abstract: While skeletal remains are known for their resilience and often serve as the final source of information for unidentified human remains (UHRs), the traditional downstream processing of these samples is challenging due to their low template nature, DNA degradation, and the presence of PCR inhibitors, typically resulting in limited...

PLANES: Plausibility Analysis of Epidemiological Signals (GitHub)

Abstract: Methods for reviewing epidemiological signals are necessary to building and maintaining data-driven public health capabilities. We have developed a novel approach for assessing the plausibility of infectious disease forecasts and surveillance data. The PLANES (PLausibility ANalysis of Epidemiological Signals) methodology is designed to be multi-dimensional and flexible, yielding an overall score based... MORE

HORIZON Newsletter – November 2024

Sample mixtures and the ability to deconvolute SNP profiles present a challenge for investigations using FGG. These mixtures are common in forensics, however, database search algorithms utilized for FGG only accommodate single-source SNP profiles. To address this gap, NBFAC and Signature Science have collaborated to implement a workflow which enables... MORE
