Science Notes – Let’s talk about sex… determination

In the first ‘Science Notes’ (CA 333), we discussed the identification of a possible female Viking warrior using ancient DNA analysis. This is a guaranteed way to confirm sex in human remains, but can be costly, time-consuming, and destructive to the bone, meaning that it is not feasible when a project needs to determine the sex of a large number of skeletons.

Science Notes – Updating radiocarbon-dating techniques

In last month’s ‘Science Notes’ we took you on a tour of the Oxford Radiocarbon Accelerator Unit, discussing the intricacies of radiocarbon dating. There is the risk of portraying the process as fixed and static, but it is always being updated with new treatments and techniques – to make the method even more precise and […]

Science Notes – Laboratory spotlight: Oxford Radiocarbon Accelerator Unit (ORAU)

For this month’s ‘Science Notes’, we went to the Oxford Radiocarbon Accelerator Unit (ORAU ) to explore the enigmatic process behind radiocarbon (14C) dating, sitting down with Professor Tom Higham, the deputy director of ORAU, and Dr David Chivall, the lab’s chemistry manager, to discuss ORAU’s history, laboratory practices, and current research, as well as future prospects.
