Effectiveness of an early intervention program for anxiety-prone toddlers in the Netherlands

What are the 'dark' components of the universe?

A research into for whom, when and why the Cool Little Kids intervention works.

Our team consists of the following members.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

Over time, the temperature in all buildings will be regulated in a sustainable manner. In this way, using gas will not be necessary anymore.

A step-by-step approach to building confidence in anxiety-prone young children.

Our mission is to recognise and treat stress and anxiety in children as early as possible, by connecting scientific research, clinical practice and education.

This thesis consists of two subjects, that are both a consequence of radiation pressure.

Children are perfect scientists: they are bursting with curiosity, they want to know how the world works and they go exploring every day. Yet many children barely get a chance to be engaged in science. A number of scientists from the Young Academy want to change that. They have received 150,000 euros…

This summer, the Universe is closer than ever. With the online astronomy summer programme Space in Your Living Room!, the Leiden Observatory brings astronauts and Leiden astronomers to the homes of children all across Europe.

The American Library Association has selected the Space Scoop website as one of the Great Websites for Kids (GWS). Space Scoop, which launched a dedicated website one year ago, provides the latest space news to educate and inspire children. The website will be included in a compilation of exemplary…

During the week of 15 November, Little Amal, the larger-than-life doll visited The Hague. Naturally she received a warm welcome by Leiden University during her visit. Little Amal (art project The Walk) was invited by Amare.

That the new building of the Campus the Hague in the Wijnhaven is literally in the governmental heart of the Netherlands should not be a surprise. But who are our neighbors besides all the ministries and the municipality? Let’s take a little walk around the neighborhood.

Australian cell biologist Melissa Little and Dutch physicist Robbert Dijkgraaf will each be awarded an Honorary doctorate at the Dies Natalis of Leiden University in February 2019. They are receiving these awards for their services to science.

From recurrent oil disasters to the outbreak of contagious diseases or major fires. Public organisations often learn too little from such crises, according to public administration specialist Wout Broekema. Staff frequently fail to communicate information adequately, which means that lessons are often…

More than 200 students completed their Bachelor’s degrees in combination with a three-year Honours programme last year. On 15 November, this resulted in a record number of certificates since the start of the Honours College 9 years ago. While listening to personal speeches, the students received their…

No matter how hard Chinese communists tried to control the economy, they could not stop the free market from flourishing. This was the message given by historian Frank Dikötter on 7 February during a lecture on the Cultural Revolution. He will be awarded an Honorary Doctorate on 8 February.

The ‘spreidingswet’ (dispersal law) has been passed by Dutch Senate and will take effect on 1 February. In the municipality of Westland, however, a majority in the council is unwilling to create 700 extra reception places.

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

Born in Hungary and moved to Austria, András Bárány grew up bi-lingual. It undoubtedly ignited his interest in languages. In Leiden, he now researches ditransitive constructions in over a hundred languages, this way taking another step in untangling some basics of human language.

A lot of our research is performed at temperatures close to absolute zero, among other reasons because this increases the sensitivity of the measurements. 

The Rutte-III coalition agreement has been presented and the commentary is flooding in. Public administration experts Arco Timmermans and Gerard Breeman examined the new agreement – as they have done for every coalition agreement since 1963 - and made a systematic analysis of it: it is very much about…

The International Institute of Air and Space Law is one of the leading international academic research and teaching institutes in the world, specialising in legal and policy issues regarding aviation and space activities in the broadest sense of the word.

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

If Dutch cinema is examined in academic studies, the focus is usually on pre-war films or on documentaries, but the post-war fiction film has been sporadically addressed.

The ongoing conflict in Kashmir is often seen as a political issue between India and Pakistan. Idrees Kanth, who has written a dissertation on the subject, believes that the people of Kashmir are the primary contenders in the conflict and should be allowed their right to decide their own political fate.…

Squatters and autonomous movements have been in the forefront of radical politics in Europe for nearly a half-century—from struggles against urban renewal and gentrification, to large-scale peace and environmental campaigns, to spearheading the antiausterity protests sweeping the continent.

The master's specialisation Child and Adolescent Psychology consists of three main parts: the mandatory and elective courses, a thesis and an internship.

With a pioneering project like the quantum computer, it’s a good idea not to place all your bets on a single horse. In Leiden’s Quantum Optics research group, instead of working on a Majorana-based qubit, people are working on a qubit based on an ‘artificial atom’. If that becomes the basis of the quantum…

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Stellar feedback is a crucial ingredient in the evolution of galaxies.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

During the development of the Humanities Campus, as many 'green choices' as possibile are being made. This concerns the buildings as well as the surrounding area. Making the campus more sustainable is measured using the BREAAM.NL method.

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

Welcome to the Hensen Lab! We are a young dynamic experimental research group starting at the Leiden Institute of Physics. Our lab addresses one of the key challenges of modern physics: understanding the interface between quantum mechanics and general relativity.

Can a newly developed, app-based, personalized maintenance program enhance the effectiveness of the exposure-based one-session-treatment for children with a specific phobia?

From self-driving cars to innovative drug development: artificial intelligence (AI) will fundamentally change our lives in many different ways. We study this technology at a deep and fundamental level. And we seek answers to questions about liability and privacy, for example. Our researchers from…

Leiden University's Citizen Science Lab supports and organizes initiatives where anyone can get started with scientific data and research. This is how we enrich research with insights from the community, make science accessible to all, and tackle important local issues together.

Are the types of school non-attendance which have been evidenced in typically developing youth also found among children and adolescents with an intellectual disability (ID)? If so, which types are most prevalent and thus in greatest need of attention, and what factors (child, family, school/environmental)…

Digital media are everywhere and are therefore a major part of our lives and the lives of our children. The new specialisation in Digital Media in Human Development focuses on the opportunities and challenges of digital media in child rearing and education.
