Doing your taxes, Netflixing or driving a car: more and more daily activities are supported by computer applications. It is challenging and expensive to test software thoroughly, leading to errors in most applications. PhD candidate Benjamin Lion made a mathematical framework to deal with this problem.…

When under duress innocent suspects can make a false confession. Why is this? Legal psychologist Linda Geven will give a talk about this at the Leiden Institute for Brain and Cognition’s Brain & Law event.

From a new generation of antibiotics and more-effective vaccines to a map of dark matter and new light on Hindu traditions. Four researchers from Leiden University have received a prestigious €2.5m ERC Advanced Grant to develop their research.

In the past decade many academic journals have started to require that researchers provide evidence of ethical review when submitting papers, for example when working with human participants or human remains.. In order to support researchers to ensure their projects are able to meet these expectations,…

Protests against textbooks on trans persons in America and against a reading hour by drag queens in Rotterdam: it has been raining protests recently against people with a gender expression that does not match their birth sex.

Tessa Verhoef from the Leiden Institute of Advanced Computer Science and Eduard Fosch-Villaronga from eLaw- Center for Law and Digital Technologies have written an article on how affective computing should be inclusive, diverse, and work for everyone.

Studying surfaces of solid materials: it may not seem relevant to energy consumption, but it is. Marcel Rost studies how platinum electrodes wear out. Those electrodes are a crucial component in the fuel cells of hydrogen-powered cars. ‘We need to make the switch from fossil fuel energy to hydrogen.…

In Bronze Age Europe many bronze objects such as axes, swords and jewels were deliberately left at specific spots in the landscape. PhD research by Leiden archaeologist Marieke Visser shows that these practices were expressions of people’s relationship with the world around them. ‘It was a completely…

With the aid of physics and a minuscule magnet, researchers have discovered a new structure of telomeric DNA. Telomeres are sometimes seen as the key to living longer. They protect genes from damage but get a bit shorter each time a cell divides. If they become too short, the cell dies. The new discovery…

By Royal Decree, Mirjam Sombroek van Doorm was appointed as a member of the Health Council of the Netherlands as of 1 January 2024.

Based partly on that hot gas, the astronomers predict that the cluster-in-formation will grow into one of the largest objects in the universe. A step closer to discovering…

When discussing the history of Islam, the focus is almost always on the history of the Sunni majority. University Lecturer in the history of Islam, Edmund Hayes wants this to change. His new ERC-funded project , focuses on the development of the early Shia community.

About one and a half million people worldwide die each year from tuberculosis. For thirty years, therapy with antibiotics has been the same, while it takes far too long and can lead to resistant pathogens. Leiden researchers from four institutes are now joining forces to develop more effective and efficient…

Fish populations in lakes and rivers have declined in recent decades. This is probably due to light and noise pollution. The Horizon Europe grant enables ecologist Hans Slabbekoorn to investigate this and improve the situation for migrating fish. In order to do so, a seven-metre-long swimming tunnel…

How is our perception of sound informed by the way we participate in the world? That is the question PhD candidate Gabriel Paiuk has been pondering in recent years. 'The way we experience sound is informed by material, technical and collective conditions that influence our interaction with the envir…

How do you progress from an immense gas cloud somewhere in the universe to a star with planets? Research by Astronomy PhD student Martijn van Gelder sheds more light on the earliest phases of this process. He will receive his doctorate on November 24th.

Have you ever experienced the feeling of awkwardness when attending a party where you didn’t know anybody? Ever felt shy at a party within the first few minutes? While this feeling is labelled loosely as feeling socially anxious, social anxiety disorder goes to a much further extent.

The guardian of our genome, the protein MutS, scans the DNA for spelling errors and makes sure they are corrected. An essential process for our health. Researchers at Leiden University Medical Centre (LUMC) have discovered precisely how this protein works by making MutS visible with cryo-electron microscopy.…

Antibiotic resistance is an economic problem. Pharmaceutical companies cannot earn much from antibiotic research, so they do not invest in it. This makes it important that universities do so, says Ned Buijs.

When a bacterium becomes more resistant to one antibiotic, it sometimes becomes more sensitive to another. To better understand this interaction, researchers from the Leiden Institute of Biology (IBL) and the Leiden Academic Center for Drug Research (LACDR) under supervision of Daniel Rozen and Coen…
