Europe's open borders are under pressure: Europe has an increasing number of Member States with governments calling for tighter border controls. Several political parties in the Netherlands are also calling for stricter border controls, among other things, to reduce the number of asylum seekers. Yet,…

Maartje van der Woude, Professor of Law and Society, was a guest on NPO Radio 1 programme 'Spraakmakers' to talk about more border fences on the EU’s external borders and the usefulness of such measures. She was also a guest on 'Vroeg!' to discuss a court case about ethnic profiling.

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

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…

How have human-environmental entanglements changed in the Gulf of San Miguel, Darien, Panama, from the first traces human practices through to the present?

Recent publications in the BLRN book series can be found below.

Allosteric modulation has long been recognized as a general and widespread mechanism for the control of protein function. Modulators bind to regulatory sites distinct from the active site on the protein, resulting in conformational changes that may profoundly influence protein function. This concept…

How can we quantify the density of species within a community through environmental DNA concentrations?

When do fire making tools appear in prehistory, and how might the use of these tools manifest in the archaeological record?

What is the role of local authorities and communities in shaping how inter-Schengen borders are understood and dealt with?

What are the host immune defence mechanisms that control intracellular infections and how are these subverted by pathogens?

The aim is to develop methods to assess environmental and occupational exposure to (individual) pesticides, to be applied in epidemiological studies investigating pesticide exposure and human health. Furthermore, we aim to investigate the potential association between exposure to pesticides and Parkinson’s…
