Some of the buildings will be reconstructed, and for others the building shell will undergo renovation. The Humanities Building is expected to…

Agricultural foods naturally vary in their detailed internal structure. To facilitate early detection of health hazards due to contamination or disease, predict maturity and minimize wastage, it is critical to take into account the internal characteristics of each individual product, as these enable…

Investigating Neolithic houses in Britain through microwear and residue analysis of stone tools

Bacteria in the teeth tell us a lot about nutrition and disease in our ancestors. It also tells us more about the immune system. This provides clues for treating modern diseases and allergies. For a long time archaeologists were irritated by tartar on the teeth of excavated skulls. They thought that…

The ability to create objects and structures with our hands has been essential to human development. This ability is something modern society is at risk of losing. Leiden archaeologists gather knowledge about ancient processes of ‘making and creating’ over the centuries, knowledge that helps our current…
