What is the effect of training children to exercise self-control? Niko Steinbeis has been awarded a major European subsidy to find the answer to this question. The innovative aspects of this research are the target group, an individual approach to the training and examining the child brain the scann…

Nematic liquid crystals form the key ingredients of most tv screens. The active version of these complex fluids forms a useful model for physicists to research the responses of active matter—like bacteria or traffic flows—to mechanical and geometrical cues. An international research team publishes their…

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

The central question in this book is whether there is a human right to family unification.

On Friday 7 March 2025 Adam Knight successfully defended a doctoral thesis and graduated.

While many healthcare professionals indicate that they frequently use placebo effects and their mechanisms, there is little formal training on how to deal with placebo and nocebo effects in clinical practice. This project aims to address this gap between scientific knowledge on placebo and nocebo effects…

This project is funded by the Dutch Cancer Society. The project will be part of an ongoing research line aimed at identifying mechanisms of cancer therapy resistance and metastasis. In this project, it will be investigated how the Grainyhead family of transcription factors controls therapy response…

On 3 December 2018 Melanie Fink, Postdoctoral Researcher at the Europa Institute, spoke at the Conference ‘Managing Migration Through Criminal Law Tools’.

A new LUMC study has changed our understanding of how cells work. Researchers have discovered that the CFAP20 protein acts as a kind of ‘traffic controller’ on DNA. Without this protein, chaos ensues, potentially causing cancer. Their findings have been published in the prestigious journal Nature.

Rigid materials break more easily than floppy ones. This simple observation allows to predict and control the width of cracks. Theoretical understanding of how materials break is useful in for example the production of cars or screens. Publication in PNAS.

How did Fustat develop between 640 and 750 to become the capital of Egypt? At the time Egypt was a province of the Islamic empire - the caliphate - that had been started by the prophet Muhammad. Original sources used by Arabist Jelle Bruning give new insights into the city. PhD defence on 2 April.

Which criteria do ED patients and therapists evaluate as most relevant for recovery? Do patients and therapists differ in their evaluations? Do eating disorder patients differ from a healthy control group in their scores on the Recovery Scale?

On Friday 16 May Juul Eijk successfully defended a doctoral thesis and graduated.

Technology is spreading its tendrils into the classroom. But who is in control?

The increasing competition in the automotive industry requires the tailored, swift development of technologically sophisticated vehicles. Therefore, the computationally expensive state-of-the-art simulation technologies are combined with optimization algorithms. An example of a real-world optimization…
