The development of the Proto-Indo-European syllabic liquids in Greek
Ancient Greek was spoken in a large number of different dialects. Although we do not find direct evidence for syllabic liquids in any of our sources, comparative evidence shows that these sounds must have been present in Proto-Greek, and that they were retained until comparatively recently in the prehistory…

New generation of graphene biosensors based on smooth surfaces and sharp edges
The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in…

Layers of dental tartar
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…

Self-assembly of Colloidal Particles
The miniaturization of machines towards the micron and nanoscale requires the development of joint-like elements that enable and constrain motion. We developed a facile method to create colloidal joints, that is, anisotropic colloidal particles functionalized with surface mobile DNA linkers that control…

Investigating a prehistoric Pan-European culture with an NWO grant: ‘One of the most transformative periods in European prehistory’
Archaeologist Quentin Bourgeois received an NWO Vidi grant to investigate the emergence of a pan-European culture in the third millennium BC. ‘We see ideas being shared across the entire continent in pre-literate societies. And not only that, for a thousand years, the same cultural ideas persist.’
