Research and design are two activities that are becoming increasingly important in the Dutch subjects O&O (‘research and design’) and NLT ('nature, life and technology’). The dissertation of Tessa Vossen (ICLON and Faculty of Science) indicates that teachers and students understand the importance of…

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

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 structure of bacterial cells provides crucial clues about their interaction with their host. What are the key structural features of a bacterial cell that determine pathogenicity? What roles do these structures play in the life cycle, and how do they change during the infection process?

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

By far the majority of users of child sexual abuse networks (or child porn forums as they are sometimes called) on the dark web do not actively communicate there but download illegal material, therefore committing a criminal offence. But they often stay under the police and judiciary’s radar. PhD candidate…

Circular economy… is it another a buzz word or a concept worth learning more about?

A comparative study on the spatial origin and development of towns in the northern Netherlands, 700-1400.

Investigating Neolithic houses in Britain through microwear and residue analysis of stone tools

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

The project falls in the context of the EU Thematic Strategy on the Sustainable Use of Natural Resources (COM(2005)670). The Institute for Environment and Resources (IES) of the Joint Research Centre (JRC) has developed three sets of decoupling indicators. Such indicators require the definition of a…

ADHD & ME aims to explore how enhancing self-esteem can break the relation between ADHD symptoms and comorbid disorders, such as anxiety and depression. In this study we assess the effectiveness of a Cognitive Behavioural Therapy (CBT) program called Competitive Memory Training (COMET) for improving…

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

LiTechAe: Percussive stone tools related to stone masonry techniques seen through experimentation and use-wear analysis.

Fishermen in the United Kingdom recently protested about the adverse effects of Brexit on their trade. It would be naive to think that covert feelings of being under threat do not exist among the Dutch population. Citizens who feel threatened become defensive, a situation that could lead to a Nexit.

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

Cotton is the most widely used natural fibre for clothes. But how polluting are our jeans and shirts actually? Environmental scientist Laura Scherer coordinated an international research project on the impacts of cotton. ‘The purchases of consumers in Europe can contribute to water scarcity in China…

What clothing is best to buy if you want to consider the environment? That question isn't so easy to answer. You have to consider the entire life cycle of a garment: from production to the moment we dispose of it. In the segment 'What's better?' of the radio programme Living Planet, environmental scientist…

This thesis describes the Multi-site All-Sky CAmeRA (MASCARA), which consists of two small robotic telescope designed to detect exoplanets around the brightest stars in the sky.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

This book, written by two representatives of Leiden Law School, describes the framework of the European Insolvency Regulation (recast) (‘EIR Recast’), in force since June 2017.

Recently, a paper by Peter Grünwald was published in the prestigious scientific journal Proceedings of the National Academy of Sciences. Grünwald is full professor of Statistical Learning at the Mathematical Institute and senior researcher at Centrum Wiskunde & Informatica.
