What are the main issues leading to polarisation and division? What is the role of social exclusion in these processes? How can we inform and design better policies to safeguard young people from falling prey to intolerance and polarisation? The DRIVE project, led by Leiden University in The Hague,…

If an algorithm has to learn to understand language, simply having a lot of data doesn’t help much. Like us, a computer has to learn the language in interaction with others. Tessa Verhoef is fascinated by how this interaction works.

We know that armed conflict breeds conflict. We also know the political, economic and demographic factors that inform this repetition of conflict. But we do not understand why accumulated conflict risk factors sometimes do and other times do not pay out in more violence. What if we go beyond macro structural…

In his article, he describes the work of the group led by Leiden astronomer Rob van Holstein.…

An international team led by Leiden astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarised light from an exoplanet. From this light they can deduct that a disk of dust and gas orbits the exoplanet. In this disk moons are possibly…

Leiden University is an international, broad-based university. We distinguish five core domains for our research and teaching activities.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

How did we come into existence? Are we alone? These questions have driven humans for centuries.

Water is all around us and is vital for all aspects of life. Studying the various compounds and life forms that inhabit natural waters lets us better understand the world around us.

It appears to be a paradox: ultra-thin material that absorbs all the incident light. Nonetheless, it does exist. Two Leiden researchers report on their research in ‘Applied Physics Letters’. The article is among the Top 20 of the most downloaded articles of this reputable journal in May.

The scientific research of the Faculty of Governance and Global Affairs is organised around a number of centres and institutes in The Hague, city of peace, security and justice.

The LLRC-committee consists of members representing participating institutes.

In a supplementary decision on 17 May 2022, the Executive Board of Leiden University has concluded that it will publish the titles of seven articles in which there is evidence of malpractice. This concerns a former staff member of the Institute of Psychology. The Executive Board considers it to be in…

Dutch politics is becoming increasingly polarised, and forming stable governments seems more difficult than ever. In the heat of the election race, a psychologist and a historian offer cool-headed advice.
