They are working hard, conclude Professor Eefje Cuppen and Lian Merkx, programme manager for energy at the Association of Netherlands Municipalities (VNG). To exchange…

Research by Leiden University Medical Center (LUMC), The Hague University of Applied Sciences and Erasmus University Rotterdam shows that about 15 percent of Dutch people do not want to be vaccinated. If better use were made of the knowledge of local professionals such as GPs, it would be easier to…

In the early 2000s, Jatropha Curcas was worldwide promoted as a promising solution to global concerns on climate change, fossil fuel depletion and rural poverty. The seeds of this plant were supposed to produce valuable oil which could be used as biofuel. Henky Widjaja, PhD candidate at the Institute…

Asexual procreation in female wasps leads to an accumulation of genetic mutations, and the shrivelling of their sex organ. Leiden biologist Ken Kraaijeveld published this discovery in Evolution. His research is one of the first experimental studies into the consequences of asexual procreation.

The central theme of Rik Mom’s research group is to identify what the electrode-electrolyte interface looks like when electrocatalysis is taking place. Using specialized forms of Raman and X-ray spectroscopy, we study the chemical state and bonding environment of the electrode surface and near-surface…

This project investigates the well-preserved agricultural terraces of the Inn valley and the evolution of resource use in the inner Alps.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

Recent studies of Neandertal body mass and skin surface indicate raised energetic requirements in this lineage compared to anatomically modern humans.

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

This interdisciplinary research project explores several adaptive machine learning methods which can give insight into the interaction between human and machine. The ultimate goal is open and natural communication between humans and AI that should result in mutual trust, cooperation and coordination…

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

Chinese materia medica (CMM), comprising a diverse array of natural substances from plants, animals, and minerals, has been integral to Traditional Chinese Medicine (TCM) throughout history. This study investigates the dynamic evolution of CMM, noting shifts in species for improved therapeutic effects…

Cut marks on the bones of bears show that people in North-West Europe used bearskins to keep warm 300,000 years ago.

Harvesting rice from the same field, without planting new rice plants? A discovery may bring this scenario closer. Leiden scientists have discovered a gene that allows annual plants to grow after flowering, instead of dying. Publication on 13 April in Nature Plants.

Müller, Braun & Fraussen examine the conditions under which commissioners appear in the news and which communication strategies they pursue.

This article provides a behavioral perspective that examines responsibility attribution to the national government (upward) and policy implementers (downward) as a function of performance relative to decision-makers' aspiration levels. The study proposes that perceived accountability increases the propensity…

The article examines how Southern European member states' newspapers portray European irregular migration governance.

Leiden evolutionary biologist Maurijn van der Zee has co-operated on an enormous international project to describe the genetic material of the pea aphid Acyrthosiphon pisum. The more than 100 authors involved in the project have published their findings in the online magazine PLoS Biology.

If male budgerigars can successfully open a puzzle box with food, they become more attractive to females. Biologist Carel ten Cate and Chinese colleagues published experimental evidence for this in a paper in Science on 11 January. Various Dutch and international media wrote about the paper.

With the new academic year just around the corner, many more students and lecturers will soon be coming to the University. What are we doing to keep our campus safe? We spoke to Martijn Ridderbos, Vice-Chairman of the Executive Board, about the new Campus Protocol, which enters into force on 31 August.…

Peter Rodrigues, Professor Emeritus of Immigration and board member of the Netherlands Institute for Human Rights, recently dealt with a fascinating case in which a woman with Russian nationality felt she had suffered discrimination.

Merijn de Bakker and colleagues of the IBL-research group of Prof. Mike Richardson provide a unique view on digit evolution in crocodiles and birds in their recent study published in Nature.

The SNP genotyping line offers flexible genotyping for small and large projects at affordable price and high quality. The use as SNPs as molecular markers is very versatile and can be used for a wide variety of scientific questions ranging from paternity analysis, conservatuion genetis towards QTL…

This is a Special Issue of the peer-reviewed journal 'Social Sciences and Missions', which provides a forum for exploration of the social and political influence of Christian missions worldwide.

Political scientist Nicolas Blarel (Leiden University) analyses the background and implications of India’s prime minister Narendra Modi’s visit to Israel.

We are pleased to invite paper proposals for the 1.5-day interdisciplinary workshop: “Who rules over migrants? Autocratic elements in migration policies”, that will take place at the University of Leiden on 14 and 15 November 2024.

Sophie Vériter explores a small state’s impact on EU security governance, a hard challenge means against big states in this policy area.
