Brain development in children with an extra X chromosome as compared to children with autism: evidence from MRI

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

Dendritic cells (DC) play a prominent role in the priming of CD8(+) T cells. Vaccination is a promising treatment to boost tumor-specific CD8(+) T cells which is crucially dependent on adequate delivery of the vaccine to DC.

The group Clinical Neurodevelopmental Sciences has expertise in individual differences in child development, in particular the development of psychopathology, ranging from mild to severe neurodevelopmental disorders.

Empowering education professionals in their continuous professional development is fundamental to our mission. We understand that a teacher’s didactic skills are as essential as their subject knowledge in delivering impactful education. To support this, we offer a broad range of training and coaching…

How public service motivation and professionalism affect decision-making in dilemma situations. Individuals who work in the public sector see themselves confronted with conflicting values, contradictory demands, and the need to serve an at times difficult to define ‘public interest’.

Atherosclerosis is the most prominent underlying pathology of cardiovascular disease and an important cause of major adverse cardiovascular events.

In this thesis, we aimed to better understand the underlying mechanisms involved in TNBC progression and metastasis formation and discover new targets to reduce breast cancer related deaths.

This book presents a new perspective on skateboarding, centred on the senses, skill acquisition, embodiment, and the concept of

Hydrogen fuel cells are expected to be pivotal in the energetic transition towards renewable energy sources such as solar and wind power. However, their industrial scalability is severely hindered by the high cost and degradation rate of platinum catalysts, one of their key components. Addressing this…

This study investigates how two social and political developments, in the UK and Germany, impacted on the experiences of minorities and the attitudes of majorities vis-à-vis tolerance in those two countries. The results provide a thought-provoking picture of the views of minority and majority groups…

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

How does governing work today, and how does society handle pressing challenges in ways that are democratic, effective, fair, peaceful, and sustainable?

Does “putting yourself in the migrant’s shoes” elicit more positive attitudes toward migration? Can perspective-taking – the active consideration of others’ mental states and subjective experiences – help undermine negative stereotypes and prejudice against migrants? We explore these questions in Ecuador,…

Together with colleagues from the Stimson Center and in the framework of the Global Governance Innovation Network, Dr. Joris Larik has recently published the report

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

Are you curious about why people are the way they are – and how they change? At Leiden University, you’ll explore social behaviour, ideas and cultures, from the past to the present and from local to global. From major cities to world religions, from philosophical questions to education and upbringing…

According to the amyloid cascade hypothesis, accumulation of beta-amyloid (Aβ) peptides initiates the pathological cascade in Alzheimer's disease (AD).

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

How to facilitate the translation of science into innovation

This article researches the public perception of terrorist attacks by measuring the importance the public assigns to attributes of terrorist attacks.

The focus of the described research in this thesis is on the oxidative stress response (Nrf2 pathway). The aim of the research presented in this thesis is to obtain more information concerning microRNAs which are involved in the Nrf2 pathway, to determine and evaluate the application of microRNAs for…

On Tuesday 3 September 2024 Straton Papagianneas successfully defended a doctoral thesis and graduated.

What drives public agencies’ propensity to engage in more extensive practices and/or to initiate more far-reaching mechanisms of accountability than those mandated by law? In other words, what are the drivers of voluntary accountability?

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

Introduction to Medieval Europe 300–1500 provides a comprehensive survey of this complex and varied formative period of European history, covering themes as diverse as barbarian migrations, the impact of Christianisation, the formation of nations and states, the emergence of an expansionist commercial…

Reactions and reaction times in cognitive tasks.

In the Psychology Lab on Wheels, we conduct innovative research together with citizens. We drive our mobile lab to people all over the country helping to bridge the gap between science and society.

Solar energy is used by photosynthetic organisms to drive energy required cellular processes. Is absorbed by two groups of pigments, located in the LHCs.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.
