A team of scientists, including Leiden Astronomer Alice Booth, has discovered silicon monosulfide molecules in the dust disk around a young star. Such molecules indicate planet formation. The team made the discovery using the ALMA telescopes. This method provides an alternative when direct observation…

One of the ambitions of the Learning@LeidenUniversity vision on teaching and learning is to foster an international and inclusive educational community in which everyone feels welcome, regardless of religion, sex, sexual orientation or cultural background. One student service that promotes inclusion…

Roll your sustainable sleeves! Our students and staff have found various ways to do just that, both at home and at our university.

Adoptees in the Netherlands generally do not use more medication than their non-adopted peers.

Knowledge is everywhere at Leiden University. It is also accessible for those who do not study or work at the University.

In the documentary ‘Pretend Student’, former students talk about why they let everyone believe they were still studying. How can you make sure you don’t end up in such an impossible situation? Four questions for Leiden Student Dean, Romke Biagioni, who worked on the documentary.

Pastoralist Societies, Rock Art and Literacy in Jordan’s Black Desert (200 BC to 800 AD)

The mission of Thamyris/Intersecting is to rigorously bring into encounter the crucial insights of black and ethnic studies, gender studies, and queer studies, and facilitate dialogue and confrontations between them.

The Sustainable Development Goals (SDGs) should have ended poverty, inequality and climate change by 2030. In a special campaign, the Dutch universities are showing how they are helping to achieve these goals.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

Galaxies in the Universe are distributed along the intricate framework of the Cosmic Web. Groups and clusters of galaxies comprise the densest regions in this network, and therefore, are excellent cosmic laboratories to study different aspects of galaxy evolution in extreme environments.

This paper written by Alexandre Afonso, Assistant Professor and Researcher at Leiden University, argues that gender norms and the political strength of the left were important structuring factors regarding why European countries choose migrant labour to expand their labour force in the decades that…

Human civilization consumes a huge amount of fossil fuels, which has resulted in an atmospheric CO2 level which has not been higher in over 800 millennia.

Modern computer-aided simulation tools used by various industries produce gigabytes of data. But currently, they take days and even up to weeks of computation effort. To make the best use of all these data, the DAMIOSO project focuses on developing algorithms and tools for managing, mining, and optimizing…

The LOFAR radio telescope produces petabytes of data every year. Radio Astronomers use complex multi-step pipelines to process this data and produce scientific images.

Heavy rainfall can cause streets to flood and basements and tunnels to overflow. Jan van Rijn investigated, together with Christiaan Lamers (formerly of Leiden University) and Ton Beenen (STOWA, RIONED), how data science can help to predict which areas are at greater risk of flooding. Van Rijn presented…

If a pill containing no active ingredients still helps, this positive expectation is called a placebo effect. A negative expectation is called a nocebo effect. Both can be produced by verbal suggestions and conditioning. According to Andrea Evers’ research group, combining these is the most promising…

Modern optimization algorithms offer solutions for architectural decisions like spatial, structural and energy efficiency. A young computer scientist from Leiden University co-authored a paper that won the Best Paper Award at a leading conference in Krakow during the summer.

Immerse yourself: read books, listen to podcasts and watch films about racism, discrimination and the colonial past.

Lecture

Cramming from a book, making notes or learning summaries. In the past these were about the only ways to memorise your course material. But that has long since changed. Multimedia is the code word. But is it effective?

National Meat Free Week, from 11 to 17 March, encourages us to choose the environmentally friendly option more often. But apart from preventing animal suffering, does eating less meat really make much difference? Three questions for Leiden Professor of Industrial Ecology Arnold Tukker.

Recent fieldwork at the vast desert region in north-eastern Jordan has revealed an immensely rich heritage of an area that is difficult to access and archaeologically less known. Professor Peter Akkermans was interviewed about his groundbreaking research in this area, known as the Black Desert.

The most commonly used method for the taxonomic identification of tree trunks is wood anatomy. The number of experts in this area is decreasing, and education to become an wood anatomists takes many years. With the help of technology computer scientists of the Leiden Institute of Advanced Computer Science…

Researchers at the Leiden Institute of Advanced Computer Science (LIACS) are collaborating on the development of a conversation tool for patients with breast, prostate and skin cancer. The aim is to create a conversation tool that can support cancer patients in their care and help them make decisions.…

Over a seven year period an international team of scientists has mapped more than a quarter of the northern sky using the Low Frequency Array (LOFAR), a pan-European radio telescope. From Leiden, Astronomer Timothy Shimwell and Huub Röttgering, among others, are involved. It reveals an astonishingly…

People are keen to make a contribution that will be valuable for scientific research. Many thousands are taking part in the Major Flu Survey. Leiden researcher Anne Land is publishing on this subject in the Journal of Science Communication.

Jamie Korporaal, who started as a junior lecturer at Leiden Law School during her master's studies and has now joined the faculty as a lecturer, will start the Labour Law specialisation after the summer. She discusses her career and this postgraduate training course with Marije Schneider, lecturer in…

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.
