Background Protein-coding DNA exhibits characteristic three-base periodicity. In unaligned DNA libraries, however, this signal should cancel if fragment boundaries are uniformly distributed across codon phases. Yet, we find that in multiple metagenomic libraries, base frequencies depended systematically on distance fro...

The Teshik-Tash 1 child whose remains were found in Uzbekistan represents the southeastern-most extent of the known Neandertal range, providing an important link with the better studied Caucasus and Altai Mountain ranges. However, due to poor DNA preservation, studying the genetics of Teshik Tash 1 has remained elusive...

Sedimentary ancient DNA provides a powerful means to reconstruct past environments and populations. However, sedimentary ancient DNA research is hindered by low success rates due to poor DNA preservation, the largely opportunistic nature of field sampling, and long delays between sampling and results—meaning that sub...
