This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

This thesis investigates the structural evolution and assembly of galaxies since the first few billions years after the big bang.

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

Responsible Research and Innovation (RRI) implies that societal actors (researchers, citizens, policy makers, business, third sector organisations, etc.) work together during the whole research and innovation process in order to better align both the process and its outcomes with the values, needs and…

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.

Evolution is all around you every day. This is the message of a Massive Open Online Course (MOOC) of Leiden University and Naturalis that is offered free of charge to anyone interested.

Certain cichlid fish in Lake Victoria seem to have adapted super-fast to changing circumstances. Dr Frans Witte from the Integrative Zoology section has been awarded an NWO subsidy (approx. € 240,000) to carry out PhD research into the rapid changes apparent in this fish species.

The explosive radiation and diversification of the advanced snakes (superfamily Colubroidea) was associated with changes in all aspects of the shared venom system. Morphological changes included the partitioning of the mixed ancestral glands into two discrete glands devoted for production of venom ormucous…

A very special occasion for the Dual PhD Centre. Vasileios P. Karakasis is the 25th PhD candidate in the history of the Dual PhD Centre, combining work with PhD research at Leiden University. Karakasis will defend his dissertation: ‘Adding Fuel to the Conflict’ on 15 October. In this interview, he discusses…

How did digital intermediality symbolise and facilitate the transfer of content from popular culture into policy statements and vice versa in the period between 1945 and the new millenium?

A global biological study has provided the most direct evidence to date that humans, and specifically cities, are the drivers of evolutionary change on Earth. Leiden University, Naturalis and the Municipality of Leiden worked on and helped fund the study.

This dissertation examines the European Union’s response to the growing problem of disinformation. It uses this case to critically analyse how societies interpret and manage information challenges such as ‘fake news’ and propaganda.

This project combines an extensive new open database on linguistic distributions, spatial modelling and areal linguistics in order to disentangle the roles of social and environmental factors on the emergence of linguistic diversity patterns of South America.

An international team with researchers from Leiden revealed how a bacterium repurposed an internal system to control its movements. Movement control is very important in host invasion, which can lead to disease. Publication on 27 April in Nature Communications.

On 17 November 2017 the Board of the Faculty of Governance and Global Affairs (FGGA) in The Hague welcomed the Mayor of Leiden, Henri Lenferink, and Alderman Paul Dirkse for a working visit, and introduced them to the campus in The Hague. During the visit, a memorandum of understanding (MoU) was signed…

Dr Johannes Magliano-Tromp has been appointed Director of Leiden University Interfacultary Dual PhD Centre The Hague as of 1st May 2016.

Ben Wielstra strives to unravel the evolution of balanced lethal systems. On 1 February he started his own lab at the Institute of Biology Leiden. Wielstra is one of five researchers at Leiden University who has been awarded an ERC Starting Grant in 2018 by the European Research Council. ERC Starting…

More attention to the needs of PhD Candidates who are not employed at universities, but combine their research with a professional career outside the academic world. That was the main wish expressed at the workshop Supervision of dual PhD candidates, organized at the Wijnhaven building in The Hague…

Which traits did change due to the invasion process of plants and how do these traits contribute to the invasiveness of such species. What is the role of carbohydrate accumulation? What is the function of carbohydrate accumulation in plants? Is genetic variation depleted in invasive species under se…

Leiden University's Kiem grants aim to help develop new interdisciplinary and interfaculty collaborations and encounters. In the first round, a Kiem grant was awarded to a group of researchers from the Faculty of Archaeology, the Faculty of Social Sciences, and the LUMC for the organisation of a symposium…

The emissions of the Chinese industrial sector alone comprise 24.1% of global emissions (7.8 GtCyr−1 in 2015). This makes Chinese industrial emissions of unique national and international relevance in climate policy. This study reports a literature survey that quantitatively describes the evolution…

How do common marmosets combine their calls into sequences and how are their vocalisations influenced by reproductive state?

A study by an international group of scientists headed by Prof. Michael Richardson showed that asymmetry in the snake lungs manifests itself early in development.

We study the link between the acoustic, behavioral and physiological health of birds and prominent pollution factors. We aim to explore causation through experimental studies on detrimental factors like traffic noise, particulate matter and chemical toxins. Our primary target is scientific progress…

Hemin Hawezy, a political & international government adviser, has started as a dual PhD candidate at Leiden University. Bram Klievink and Toon Kerkhoff are supervising his research on the organisation of digitalisation in government; a good example of transdisciplinary collaboration.

What the Sex Lives of Bugs, Birds, and Beasts Tell Us About Evolution, Biodiversity, and Ourselves, Menno Schilthuizen reports from the front lines of evolutionary biology, on a quest to make sense of the origins, workings and evolution of our and other species’ reproductive selves.

The logic seems inescapable indeed. The bigger the population, the higher the probability it contains an Einstein. Hence, bigger populations are more likely to develop complex culture.
