Degraded DNA is used to answer questions in the fields of ancient DNA (aDNA) and forensic genetics. While aDNA studies typically center around human evolution and past history, and forensic genetics is often more concerned with identifying a specific individual, scientists in both fields face similar challenges. The overlap in source material has prompted periodic discussions and studies on the advantages of collaboration between fields toward mutually beneficial methodological advancements. However, most have been centered around wet laboratory methods (sampling, DNA extraction, library preparation, etc.). In this review, we focus on the computational side of the analytical workflow. We discuss limitations and considerations to consider when working with degraded DNA. We hope this review provides a framework to researchers new to computational workflows for how to think about analyzing highly degraded DNA and prompts an increase of collaboration between the forensic genetics and aDNA fields.

Accurately identifying evolutionarily significant units (ESUs) is crucial for conservation planning, especially for species like pangolins threatened by overhunting and habitat loss. ESUs help categorize different pangolin populations, aiding in understanding their genetic diversity and distribution, which is vital for targeted conservation efforts. This research generated mitochondrial genomes from historical museum specimens of Sunda pangolins () from underrepresented locations, uncovering a new evolutionary lineage from the Mentawai Islands that diverged from Indochina and west Sundaland populations around 760 000 years ago.

The likelihood ratio (LR) is a recommended metric for assessing the strength of genetic information in relationship testing, one of the most important tasks in forensic science. LR calculation incorporate population frequencies, which is affected by population substructure. This study utilized population frequency data from 18 short tandem repeat (STR) loci across 13 Chinese populations, encompassing both majority and minority ethnic groups.

Objective: The current study aims to examine executive and social functioning in children and adolescents with Noonan syndromes, which contributes to the understanding of the cognitive and behavioral profile of this population and possible treatment options.
Method: A total of 26 children and adolescents with Noonan syndromes (including Noonan syndrome, Noonan syndrome with multiple lentigines, and Noonan-like syndrome with loose anagen hair; mean age = 11.92 years, SD = 2.

We report the forensic and clinicopathological spectrum of 14 postmortem cases involving the vertebral artery. In all cases, there was either pontocerebellar infarction (n = 8) or subarachnoid hemorrhage (n = 6). The underlying pathology of the vertebral artery was segmental mediolytic arteriopathy (n = 5), traumatic rupture of the arterial wall (n = 3), arterial dissection (n = 2), or atherosclerosis (n = 4).
