The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Atherosclerosis is a chronic inflammatory disease affecting millions of people world-wide.

On the occasion of prof Paul van der Heijden’s stepping down as Rector Magnificus and President of the Executive Board of Leiden University in 2013 the Chair bearing his name on Social Justice was established. It was a “farewell present” of the Leiden University to it’s Rector.

From basic science to real-world interventions

Building a Deep Cross-media Transfer Network to extract visual relations that relieve the problem of insufficient training data for visual tasks.

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

This dissertation focuses on the overt marking of φ features encoded on perfective active auxiliaries in a group of Southern Italian dialects.

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.

On 21 September 2022 H. Hu successfully defended a doctoral thesis and graduated.

The Role and Effectiveness of the G20. In this article, published in The Changing Global Order part of the United Nations University Series on Regionalism book series, author Jaroslaw Kantorowicz discusses the evolution of the G20.

This paper investigates possible convergence of issue salience of terrorism among citizens within the European Union for ten jihadist attacks in the period 2015–2017 using Eurobarometer survey data.

This volume publishes the proceedings of the eleventh annual University of Chicago Oriental Institute Seminar. It uses the sphere of legal institutions as a prism through which to consider gender relations in the ancient world, both in the Near East and beyond. It examines how similar issues were manifested…

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

This article examines the consequences of stereotypical beliefs regarding gender, traits, and leadership styles for manager preferences.

How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

In recent years, the question why citizens (do not) support democratic innovations has attracted increasing academic attention. In this research note, Van Der Does & Kantorowicz for the first time empirically verify what drives citizens’ instrumental considerations in their evaluation of a DI.

Metabolomics is a powerful tool that can provide a comprehensive insight into the complexity of human biology and the pathophysiology of diseases. By analyzing the metabolome, which refers to the complete set of small (endogenous) molecules (with a mass <1500 Da) present within a given biological system,…

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

What are the mechanisms involved in the reconciliation of value conflicts and which interventions are capable of resolving such disputes?

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

Complaints against decisions not to prosecute in socially sensitive issues.

Mission: The Environmental Biology department aims to increase the scientific understanding of how current and emerging anthropogenic threats affect biodiversity and ecosystem services. Through this understanding they facilitate strategic management of natural resources by addressing urgent challenges…

The PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.

How do mycobacteria subvert the defenses of host immune cells?

Wout Broekema highlights how organisations not only learn from crises but also forget, losing crucial knowledge and practices over time.

Can we link multiple components from herbal extracts with their biological activities?

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

Understanding individual differences in self-regulation in boys with ODD/CD on the level of brain, cognition and behavior

PURPOSE: The aim of the study was to develop a cheap and fast method to produce hollow microneedles and an applicator for injecting vaccines into the skin at a pre-defined depth and test the applicability of the system for dermal polio vaccination.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

This thesis describes the design and synthesis of fragments of various cell wall carbohydrates of the Streptococcus species, including the branched Group B-specific antigen (GBC) of Group B Streptococcus, glycerol phosphate (GroP) modified group A carbohydrate (GAC), and the O-acetylated type 1 capsular…
