Different groups can have different memories of the same historical event. This can lead to conflict but does not have to. How is this, and how can countries and people reconcile with the past?

In 2021 the Leiden Osteoarchaeology Lab hosted an international workshop on methods to study past physical activity. It aimed to tackle a niche topic with the field: namely the method of studying muscle attachments to bone. Dr Sarah Schrader, one of the organisers of the workshop: ‘You can quantify…

Chen Wang has recently finished her doctoral research and will be defending her dissertation on May 13th. For her PhD she researched the lead in artefacts from ancient China, using isotope analysis to match them to their origins. She applied analytical methods to new contexts and used the data from…
