Astronomer and Marxist Anton Pannekoek was a remarkable figure. This book aims to study the connections between his life as a socialist theorist and as a pioneering scientist through the prism of Pannekoek's biography.

Over time, the temperature in all buildings will be regulated in a sustainable manner. In this way, using gas will not be necessary anymore.

On 29 april 2020, Beth Van Schaack defended her thesis 'Imagining Justice for Syria: Water Always Finds Its Way'. The doctoral research was supervised by Prof. C. Stahn.

Adults are more likely to reoffend after a short prison sentence than comparable adults with a non-custodial sentence, Leiden University research shows. This is true for the likelihood and extent of repeat crime.

Dutch political parties have presented their own 'solutions' to make society 'safer'. How do the party positions compare with scientific research on crime reduction?

Do sustainability values play a role in motivating people to act for biodiversity in successful projects and in successful leadership action? And how could these values be incorporated in current economic valuation methods?

This book is about the workings of networks of the mobile in Africa, a continent usually associated with the ‘global shadows’ of the world.

The formation of stars and planets happens over multiple scales, which can interact. In particular, planet formation happens in the dense, complex environment of star forming regions.

Chenyu Cheng defended her thesis on 6 April 2017.

Isabel van Vledder and Dieuwertje van der Vlugt, 2 astronomy students from Leiden University, have mapped the entire Milky Way galaxy in dwarf stars for the first time. This result is the most comprehensive model ever for the distribution of these stars. The findings appear in a new paper in Monthly…

How much mortgage interest can I claim back according to law? Or maintenance payments, how much do the tax authorities let me deduct? Many citizens struggle with questions about the application of tax legislation. Roberto van den Heuvel investigated in what way tax legislation should provide clarity…

Many problems in criminal law can be predicted by the academic world and using knowledge from criminal law practice, says criminal lawyer Professor Patrick van der Meij.

Four videos tell the story of the history of Leiden University. The films were premiered on 2 November during the Leiden Film Festival.

In higher education intermediate assessment is used in different ways. In her PhD research Indira Day (ICLON) shows that lecturers should be able to continue to have the freedom to use various test forms, because not one type of test is optimal. Defence on June 28, 2018.

Leiden Physicists have found evidence for the Berry-force that could be used for driving tiny nanomotors, just like a river drives a water wheel. Nanomotors could be used for drug delivery in the human body. Publication in Beilstein Journal of Nanotechnology.

With the emergence of social media platforms such as Twitter, Facebook and Instagram, it’s easier than ever to share information. Including disinformation. During his PhD computer scientist Xueqin Chen developed a new way to recognise fake news and predict how messages spread within online social networks…

A new computer simulation shows the promising possibilities of the booming field of topology. Smartly designed mechanical structures carry sound exclusively one way and are immune to fabrication errors. Publication on 17 July in Nature Physics.

Rigid materials break more easily than floppy ones. This simple observation allows to predict and control the width of cracks. Theoretical understanding of how materials break is useful in for example the production of cars or screens. Publication in PNAS.

Researchers from Japan and the Netherlands who were previously involved in the discovery of an exoplanet with huge rings have now calculated that the giant rings may persist more than 100,000 years, as long as the rings orbit in the opposite direction to that of the planet around the star. Their findings…

For centuries, astronomers have studied the universe by collecting light signals. Since 2015, the confirmation of an important prediction of Einstein allows us to explore the universe in a new way: through gravitational wave radiation. Astronomy PhD candidate Valeriya Korol proposes to use these gravitational…

What is dark matter? How do supermassive black holes form? ‘Primordial’ black holes might hold the answer to these long-standing questions. Leiden and Chinese cosmologists have identified a new way in which these hypothetical objects could be produced just after the Big Bang. Publication in Physical…

Using the Dutch-led Low Frequency Array (LOFAR) radio telescope, astronomers have discovered unusual radio waves coming from the nearby red dwarf star GJ1151. The radio waves bear the tell-tale signature of aurorae caused by an interaction between a star and its planet. The radio emission from a star-planet…

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.
