Is our universe built up out of warm or cold dark matter? The standard model assumes cold dark matter particles, but astronomer Sylvia Ploeckinger is now testing the possibility of a warm counterpart: sterile neutrino’s. For this project, she received an NWO Physics/F grant, a special grant for women…

Besides being the author of such a classic work of literature as The Hobbit, Tolkien was also Professor of English Language and Literature in Oxford. How did he incorporate his research in his fiction? An international conference on the subject is being held in Leiden on 18 June.

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

Intelligent machines are going to make ethical decisions too. Should a self-driving car be allowed to slam into pedestrians to save its passengers from a head-on collision? Should a negotiation app be able to detect stress in your opponent’s voice? And who makes these decisions: the user, the system’s…

The research question is that unconscious perseverative cognition (UPC) is responsible for a considerable part of cardiovascular (CV) activity that occurs even in the absence of threats and other stressors that one may encounter in one’s daily life.

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

My ERC Starting Grant, funded with €1.5 million for 5 years as part of the Horizon 2020 research and innovation program, is focused on building the early warning system WARN-D to reliably forecast depression in young adults before it occurs. Why depression, and why prediction?

Eleven Leiden researchers have been awarded an 800,000 euro Vidi grant by the Dutch Research Council (NWO). This will enable them to develop their own innovative line of research and start their own research group.

Scientists often need to make sense of complex systems without knowing the important parameters or even without access to all the information. A collaboration of network theorists, including Diego Garlaschelli (IMT Lucca/Leiden), has now published a review article in the inaugural issue of Nature Reviews…

How can Ronald Mulder run his skates across an ice layer at 60 km/h? His skating blades get help from a lubricating layer of meltwater. In Leiden, physicists found this explanation to be incomplete. Theoretician Hans van Leeuwen and experimental physicist Tjerk Oosterkamp searched for a deeper answe…

In these uncertain times when we all have to adapt to new circumstances, LUC is working hard to develop and implement changes in procedures and guidelines for staff and students. We would like to explain how this is organized, because staff and students are not always aware of the many steps that are…

An international team of more than 200 astronomers from 18 countries has published hundreds of thousands of unknown galaxies. The data are part of a project lead by Leiden professor of Observational cosmology Huub Röttgering. Both Dutch and international media reported extensively about the publica…

The Leiden physics institute LION has bought a painting by the American physicist Gregory Horndeski, who wrote a brilliant article about gravity in 1974. After being ignored for 35 years, Horndeski's paper became a huge hit among cosmologists, unbeknownst to Horndeski himself, who had made a career…

More effective diagnosis and prognosis than ever, with less intrusive medical screening? Scientists from Leiden, Delft and Rotterdam are well on the way to achieving just that. Imaging professors Serge Rombouts and Wiro Niessen are working on an extremely rigorous, self-learning adviser for radiologists.…

The Leiden University Political Science bachelor’s programme enjoys a high popularity. To assure the quality of education, the number of students it admits is limited. This is known as a 'numerus fixus'. If there are more applications than this ‘numerus fixus’, a selection and placement procedure will…
