What does it mean to eat healthily and responsibly? This question is gaining a new urgency now that in many countries undernourishment is being overtaken by diseases of affluence, such as obesity, and we are also becoming more aware of the environmental impact of our eating habits. It’s time to take…

The Green algae Chara as model system for intra and inter cellular transport processes.

Prof. Elizabeth de Lange is concerned with the allocation of resources for the conduct of science towards the goal of best serving the public interest. Also, while she underscores that there is still the need for using animals in drug research, she is concerned about this use, and advocates the use…

The Programme Standards project sets out guidelines on how to structure the education offered at the Faculty of Humanities. The project aims to distribute the teaching effort in a transparent way and to organise the programmes so that the best possible teaching can be provided in an efficient manner,…

1. What is the exact role of PIN proteins in PAT? 2. How is PIN polarity established, and how is it modulated by AGC kinase-mediated phosphorylation? 3. What is the role of the AGC kinase, as modulators of PAT, in translating environmental signals, such as gravity, light or mechanical stress, to plant…

This minor critically examines the complexities of food sustainability through ecological, socio-economic, political, and cultural systems.

This research project is supported by an NWO Aspasia grant, DeepDish TV, crowd-sourced funding, and the Democracy and Media Foundation.

Researchers at LIACS are working to devise the computers of tomorrow that will be the backbone of the Cloud and Edge computing paradigms as well as the Internet of Things. In this respect, we are involved in research and development of high performance computing systems, embedded & real-time computing…

The research programme Probability Theory focuses on probability theory and on operations research.

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 are the effects of light pollution from cities and bridges and noise pollution from passing vessels and nearby road traffic on migratory fish passage and spawning in rivers?

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

How do governments distribute resources across economic sectors during a crisis? And why do some sectors receive more than others? The recent COVID-19 pandemic has highlighted the urgency of these questions. In this paper, we explore the extent to which a political economy…

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

Our research at CWTS is organized in three focal areas. These focal areas represent our core areas of interest, as defined in our knowledge agenda for the period 2023-2028.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

The availability of indicators based on social media has opened the possibility to track the online interactions between social media users and scholarly entities.

Food security is challenged by a growing global population and by climate change. Drought and soil salinity are considered the most important ones that inhibit crop yield and distribution. Worryingly, climate change is predicted to increase not only their frequency and severity, but also their co-occurrence,…

The research of the unit is aimed at the development of models to explain and describe the influences in social systems. Social influences are studied in three ways: from the perspective of group dynamics, from an individual-cognitive perspective, and from an economic and consumer psychological pers…

This book is about the archaeology of indigenous peoples who thrived across the Caribbean, the Guianas, and the Lower Amazon basin just before the European invasion, and who also remained central to the early history of conquest and colonization.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

In this article, Ben S. Kuipers and Joanne Murphy review recent critiques of leadership theory and practice.

To increase clinical success rate of drugs, a better understanding of drug action mechanism and disease dynamics is required. Metabolomics, which studies small molecules involved in biochemical processes in organisms, has shown to be a useful tool for this better understanding.
