The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

Het is een van de meest besproken onderwerpen van dit moment: hoe bannen we seksueel grensoverschrijdend gedrag en geweld uit? Alumnus Femke Eisma is woordvoerder van Mariëtte Hamer, de regeringscommissaris die dit hardnekkige maatschappelijke probleem moet aanpakken. Eisma studeerde Nederlands in Leiden.…

Persoonlijke briefjes uit middeleeuws Rusland? We kennen wel veel officiële en kerkelijke documenten, maar de vondsten van stukjes beschreven berkenbast uit Novgorod geven op een unieke wijze inzicht in hoe 'gewone' mensen dagelijks met elkaar communiceerden.

Cryptocurrencies zijn geëxplodeerd op de mondiale financiële markten, waarbij de waarde van een enkele bitcoin is gegroeid van ongeveer 800 USD in 2016 tot 67.000 USD in 2021.

In de zomermaanden zijn er drie grote introductieweken - EL CID, HOP en OWL - voor nieuwe studenten, maar ook halverwege het academisch jaar starten er nieuwe studenten met hun studie in Leiden of Den Haag. Denk bijvoorbeeld aan internationale studenten die hier een aantal maanden op uitwisseling komen.…

In een gezamenlijke brief doen de Leidse studentenverenigingen een oproep aan alle studenten: houd anderhalve meter afstand en zoek alleen sociaal contact als je gezond bent. De verenigingen drukken studenten op het hart de coronamaatregelen goed na te leven, om zo een lokale opleving te voorkomen.

In this dissertation (titled: Exploring the Synergies between Transfer in Reinforcement Learning and Procedural Content Generation) we explore how the two research fields named in the title, namely Transfer in Reinforcement Learning (TRL) and Procedural Content Generation (PCG) can synergize togethe…

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

Lipid formulations have demonstrated strong potential for nucleic acid delivery,particularly with the success of COVID-19 vaccines. Despite these advances, manyaspects of lipid formulations remain unclear.

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

Advanced mass spectrometry of glycosphingolipids takes the central stage in this thesis. Investigations focus on characterization of glycosphingolipid metabolism in health and disease with emphasis to the detection and accurate quantitation of known and so far unknown glycosphingolipids and closely…

This thesis manuscript explores the use of video games as tools for conceptual exploration and academic research.

This thesis investigates how cell shape and collective behavior influence the dynamics and structure of biological tissues, which are crucial for understanding processes like embryonic development, tissue regeneration, and metastasis.

Global Environmental Extensions Multi-Regional Input-Output (EE-MRIO) analysis is often used to analyze how changes in global and national demand for products lead to socioeconomic and environmental impacts at the national level.

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

The molecular mechanisms that instigate a healthy cell to become malignant are fueled by (epi)genetic alterations in so-called driver genes.

Understanding DNA repair mechanisms is essential for advancing plant biotechnology and crop improvement. This study investigates how double-strand breaks (DSBs), induced by CRISPR/Cas systems, are repaired in the model plant Arabidopsis thaliana, and how these processes influence Agrobacterium tumefaciens…

Tin electrodeposition applications have rapidly evolved in the past 25 years.

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.
