Imagine we could do what green plants can do: photosynthesis. Then we could satisfy our enormous energy needs with deep-green hydrogen and climate-neutral biodiesel. Scientists have been working on this for decades. Chemist Chengyu Liu will receive his doctorate on 8 June for yet another step that brings…

University lecturer Lucien van Beek has been awarded a LUF Praesidium Libertatis Grant. He will use the sum of 75,000 euros to research the thinking of people in ancient and prehistoric times. To do that, he will look for unusual or striking metaphors in the earliest Indo-European languages.

For the first time, it was shown in living cells how the bacterium E. coli regulates genes that help it survive in a new environment. Biochemist Fatema Zahra Rashid managed to do this using a technique she fine-tuned. Her research into changes in 3-dimensional chromosome structure offers clues for ways…

Increasingly, citizens are going to court to challenge decisions by the Public Prosecution Service not to prosecute in certain, sometimes socially sensitive, cases. Yet, these citizens are not always taken seriously as democratically engaged persons. A mistake, says Sophie Koning.

Starting February 6, the Leiden interdisciplinary research programme Global Transformations and Governance Challenges (GTGC) will host a lunch seminar series on pressing global governance issues. The series will feature researchers from various disciplines. It promises to be a trove of inspiration and…

The euro crisis of 2010 has shown that the Eurozone lacks economic cohesion and that EU fiscal integration is needed for a stable euro. But can this integration exist without clashing with the national constitutional interests of the Member States? Frederik Behre looked into this matter in his PhD-thesis…

Video conferencing from your sitting room and algorithms on social media that know your interests: new technology is an increasingly integral part of our lives. At the same time there is a growing call to protect our privacy, and this is causing friction, at the University too. In part because of the…

The challenge: take three hundred students from vastly varying disciplines and teach them the basics of academic thinking in twelve lessons. Impossible? Professor Ben Arps and his team of tutors succeeded. It resulted in a large amount of positive student evaluations.

Anthropologist Anouk de Koning about the tottering welfare state and the dilemmas of a government operating as a nearby, friendly partner.

The interplay between literature and law is what Frans-Willem Korsten wants to address as a brand-new professor of Literature, Culture and Law. That means doing research, but certainly also teaching. 'The Hague is of crucial importance for the humanities.'

North Korea may seem like an isolated country but it has strong ties with African regimes. This alliance, which trades in arms despite international sanctions, is increasingly operating out of the liberal world order’s sight, PhD candidate Tycho van der Hoog warns.

There has been a lot of media attention for the report recently completed by the Institute of Environmental Sciences (CML) from Leiden University. However, it has long been known that Dutch surface water contains too many toxic pesticides. ‘We will have to improve our ways of life together with many…

An international team of astronomers, including Leiden PhD student Elia Pizzati, has observed several ancient quasars that, surprisingly, appear to be floating alone in the early universe (less than a billion years after the Big Bang). Until now, astronomers, based on models, assumed that quasars are…

Theoretische onderbouwing laat zien dat wijkrechtspraak effectief kan zijn. Dat blijkt uit een vandaag gepresenteerde studie in opdracht van het WODC. Rechters kunnen vanuit een zitting in een wijkcentrum vaak beter ingrijpen dan vanuit de rechtszaal en met meer vertrouwen.

In the Netherlands, people probably grew up with De Fabeltjeskrant (a children’s show, ed.), but in France an introduction to fables plays a much more important role in a child's upbringing. PhD candidate Céline Zaepffel studied the role of fables in French education and teaching methods. It turns out…

Few researchers see potential in research on glioblastoma, an incurable brain tumour. Alexander Kros brought together colleagues who are up to the challenge. European research funder ERC recently made 10.6 million euros available, a year earlier NWO provided 3 million euros. ‘In six years, we certainly…

How safe are the nanoparticles in transparent sunscreen, anti-odour socks and bacteria-resistant plasters? Although microbes are present on all organisms, the tools that estimate the safety of nanomaterials still hardly take them into account. Bregje Brinkmann explored the role of these microbes during…

Plants can’t run away from enemies. Still, it would like to keep life-threatening herbivores at a distance. This can be done with odours. Klaas Vrieling of the Institute of Biology Leiden found out with his team how plants change odour production to keep the munchers at a distance.

There has also been a slight decrease in trust between…

Leiden ecotoxicologist Martina Vijver helped shake a European policy proposal in a single weekend. Not with a new experiment, but with years of research on pesticides – and an urgent letter that reached Brussels.

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.
