Residues from ancient artifacts can help identify which plant species were used for their psychoactive properties, providing important information regarding the deep-time co-evolutionary relationship between plants and humans. However, relying on the presence or absence of one or several biomarke...
Dental calculus is becoming a crucial material in the study of past populations, with increasing interest in its proteomic and genomic content. Here we suggest further development of protocol for analysis of ancient proteins and a combined approach for subsequent ancient DNA extraction. We tested th...
Since the discovery that cytosine deoxynucleotides could be methylated (dC5m), not much is known in higher eukaryotes about modifications affecting other deoxynucleotides. Here, we now report that we detected N-6-methyl-deoxyadenosine (dA6m) not only in frog DNA, but also in other species including ...
