The 0.05%: Proof of concept for ZooMS as a large-scale screening tool for ancient DNA research

Brown, S., Higham, T., Slon, V., Pääbo, S., Meyer, M., Douka, K., Brock, F., Comeskey, D., Procopio, N., Shunkov, M., Derevianko, A., & Buckley, M. (2016). Identification of a new hominin bone from Denisova Cave, Siberia using collagen fingerprinting and mitochondrial DNA analysis. Scientific Reports, 6: 23559.

DNA sequencing has revolutionised our understanding of archaic humans during the Middle and Upper Palaeolithic. Unfortunately, while many Palaeolithic sites contain large numbers of bones,  … ⇒

Inferring age of death (or tooth loss) from dental DNA methylation patterns

Giuliani, C., Cilli, E., Bacalini, M. G., Pirazzini, C., Sazzini, M., Gruppioni, G., Franceschi, C., Garagnani, P., & Luiselli, D.. (2016). Inferring chronological age from DNA methylation patterns of human teeth. American Journal of Physical Anthropology, 159(4): 585–595.

Objective: Current methods to determine chronological age from modern and ancient remains rely on both morphological and molecular approaches. However, low accuracy and the lack of standardized protocols make the development of alternative methods for the estimation of individual’s age even more urgent for several research fields,  … ⇒

Towards on-site optical radiocarbon dating

Galli, I., Bartalini, S., Ballerini, R., Barucci, M., Cancio, P., De Pas, M., Giusfredi, G., Mazzotti, D., Akikusa, N., & De Natale, P. (2016). Spectroscopic detection of radiocarbon dioxide at parts-per-quadrillion sensitivity. Optica 3: 385-388.

High-sensitivity radiocarbon detection has been, until now, a prerogative of accelerator mass spectrometry (AMS). Here we present a compact and simple spectroscopic apparatus, based on saturated-absorption cavity ring-down, approaching the ultimate AMS sensitivity.  … ⇒

White bone in Golok: A field report

My good friend Hannibal Taubes writes:

Incidentally, RE your black bone / white bone post, I asked my Tibetan teacher if she’d heard any such expression. She’s a 50-something Golok woman from a village at the foot of Mt. Amnye Machen. According to her, Tibetan rus means “bone” and also means “clan” (ch. 部落). (To be honest, I’m not sure what “clan” means here; there seem to be a number of different Tibetan words in use that mean something like that,  … ⇒
