The Laboratory for Human Osteoarchaeology specialises in the macroscopic and microscopic analysis of human remains. We use cutting edge scientific approaches to address archaeological, historical, and anthropological research questions. In addition to paleopathological, histological, and 3D scanning…

Examining mediation and moderation.

These syntheses allow the team to determine the extent to which schools-based interventions are effective at targeting radicalisation-related outcomes.

Day-to-day activities are important in the development of social identities, the establishment of social standing, and the communal understanding of societal rules. This perspective is broadly referred to as practice theory and relates to the power of an overarching social structure and the individual…

The Leiden Institute of History approaches early modern and modern European history from comparative and transnational perspectives.

The Faculty of Archaeology at Leiden University offers education in Human Osteoarchaeology. We offer courses in our one-year Master’s track in Archaeological Science, resulting in a Master of Science degree after completion.

The growing popularity of corporate self-regulation to address supply-chain issues puts Corporate Social Responsibility and specifically codes of conduct, at the centre of attention. In this article, Jaroslaw Kantorowicz, Sarah Vandenbroucke and Yvonne Erkens analyse supplier codes of conduct of multinational…

Rector of Institut Teknologi Bandung (ITB) Prof. Tatacipta Dirgantara, accompanied by Dr. Endra Gunawan, Director of Partnerships, visited Leiden University on 23 April 2026. The delegation was welcomed by the President of the Executive Board, Prof. Luc Sels.

The seventh Leiden wall formula has been finished. Over the last few weeks, mural artists Ben Walenkamp and Jan Willem Bruins have painted Christiaan Huygens' pendulum formula on 'De Brandmeester' an old drill and hose tower in de Plaatsteeg, just behind the Breestraat in Leiden.

An international group of scientists, led by Leiden physicist Sense Jan van der Molen, has developed the first switchable molecular diode. You can turn this on and off through humidity. Vice versa, it is a humidity sensor at the nanoscale. Publication on 4 December in Nature Nanotechnology.

Stack two layers of graphene, twisted at slightly different angles to each other, and the material spontaneously becomes a superconductor. Science still can't explain how something so magical can happen, but physicists use special equipment to reveal what is taking place under the surface.

NWO has assigned Physics Vrije Programma grants to five collaborations of physicists. Leiden University is involved in three of them.

Master students Lotte Koemans and Mandy Meijer have developed an audio tour which takes you past all six wall formulas in the inner city of Leiden. In this movie, they walk the tour themselves.

Stacked layers of graphene can act like a mirror for beams of electrons. Physicists Daniël Geelen and colleagues discovered this using a new type of electron microscope. In an article in Physical Review Letters, they describe their results, which could lead to the development of optics for electron…

A national survey conducted by Dutch newspapers Dagblad van het Noorden, Turbantia, Brabants Dagblad and the Dutch Federation of Trade Unions (FNV) shows that staff working in disability and mental health care often face violence in the workplace. In the three northern provinces of the Netherlands,…

The largest fertility clinic in the Netherlands lied to women, sperm donors, and the Health and Youth Care Inspectorate. On ‘Nieuwsuur’, Mirjam Sombroek van Doorm, Professor of Law and Health, foresees legal consequences: 'The situation is too serious.'

A new almost free childcare system may sound ideal, but it also comes with risks for parents. Psychologists from Leiden University and research firm D&B have concluded that the system can cause uncertainty and stress, particularly among vulnerable groups.

Mass, time, space, and complexity — physicists in Leiden are launching eight new research projects tackling some of the most fundamental themes in quantum mechanics. Their goal: to push the limits of current quantum theories.

On Thursday 3 November Leiden University will celebrate the official opening of two wall formulas in the city centre. As of now, Snell’s law and the Lorentz force formula shine on two walls in the heart of Leiden. They are part of a project to display at least ten groundbreaking formulas with a Leiden…

On Monday 7 September Food Citizens rejoined after the end of fieldwork during a workshop day at the old mill yard 'Molen de Ster' in Utrecht.

On February 2nd the book Beelden zonder weerga appears, written by professor in science history Dirk van Delft and biochemist Ton van Helvoort. They describe the rich history of electron microscopy, which comes to a conclusion in the final chapter with the current state-of-the-art ESCHER microscope…

An acute shortage of social care staff means that family members often quit their jobs to care for relatives with severe disabilities. This seems too good to be true – and there is a catch. Barend Barentsen, Professor of Labour law, discusses this on Dutch consumer programme ‘Radar’.
