Are social anxiety and public speaking anxiety associated with characteristic patterns of stress responses…

Globalisation leads to more contradictions between national and international tax norms. It therefore seems necessary to revise the fiscal legislation. This is not only due to the problem posed by multinationals, but also to changing norms regarding tax burden distribution. Fundamental research on the…

What role(s) do border officials play in the enforcement and management of border control and border mobilities and how do these roles relate to the personal, organisational and larger societal context within which these officials operate?

Throughout all domains of life, from bacteria and archaea to eukaryotes, genomes adopt well-organized three-dimensional structures that can change in space and time to accommodate preferred transcriptional programs for environmental adaptation, the maintenance of cellular identity and differentiation…

This part entails the analysis of an extensive sample of animal bone (c. 30,000 pieces) retrieved from well-defined archaeological contexts of the early period at Tell Sabi Abyad, c. 6800-6200 BC. It comprises aspects of taphonomy, ageing and osteometry, the reconstruction of the local spectrum of domestic…

Which consumer groups post the greatest cost to public health and the planet through their food choices, and how can we use this fine-scale information to accelerate a sustainable dietary transition?

We aim to unravel the complex and intertwining regulatory systems that control development and antibiotic production in streptomycetes.

In this project, we aim to obtain a quantitative understanding of the role of the immune system in tumor regression, of the role of tumor cell heterogeneity in cancer growth and of tumor cell migration properties.

On 31 January 2024, Alex Schilin defended his dissertation ‘United in Distinctiveness: The Institutionalisation of Differentiated Integration in Economic and Monetary Union during the Sovereign Debt Crisis.’ What motivated him to research this specific topic, and how did he tackle this project? And…

A poor woman from Java plucks three cocoa fruits from a plantation, to use as seedlings. The judge convicts her of theft, but she is not sent to prison. This is one of the examples of legal differentiation that Adriaan Bedner, Professor of Law and Society, will be examining in Indonesia. Inaugural lecture…

When the tokay gecko loses its tail, a new one grows from resident stem cells at the stump. Each tissue type - muscle, bone, blood vessels and skin - develops from specific stem cells. This discovery by Luthfi Nurhidayat holds potential implications for advancing regenerative medicine in humans. Nurhidayat…
