De bacheloropleiding Pedagogische Wetenschappen duurt drie jaar. In het eerste jaar maak je kennis met de verschillende disciplines en daarna specialiseer je je in de richting die je het meeste aanspreekt.

Het studentenleven is nu ook op een andere manier hoorbaar in Leiden. Vanaf 6 juni speelt het stadscarillon van het stadhuis ieder uur bekende melodieën van het Leidsch Studenten Cabaret uit de jaren ’50. Zoals ‘Laat je zoon studeren’.

Bijna zeshonderd aankomende eerstejaars studenten bezochten op dinsdag 15 augustus hun nieuwe Faculteit der Wiskunde en Natuurwetenschappen. Ze werden welkom geheten met onder andere een vossenjacht, fotoshoots, warme woorden en vooral heel veel vloeibare stikstof.

De Plaatselijke Kamer van Verenigingen (PKvV) heeft een online mediaplatform gelanceerd waarop alle 24 Leidse studentenverenigingen verenigd zijn. Dit mediaplatform is de laatste maanden ontwikkeld in samenwerking met Universiteit Leiden, Hogeschool Leiden en Leiden Marketing.

2020 was een bewogen jaar. Ook in onze foto's was dit goed te zien: anderhalve meter afstand, een lege universiteit, plechtigheden bijwonen via het scherm en werken vanuit huis. De beeldredactie selecteerde de twaalf meest opmerkelijke foto's van het afgelopen jaar.

Precies een jaar geleden ging de universiteit plotseling grotendeels op slot, midden in het collegejaar. Opeens zaten we op die derde maandag in maart allemaal thuis en moesten we, vanaf een krappe zolder- of studentenkamer, online studeren en werken. Het gedenkwaardige coronajaar in beeld.

Van hulp bij natuurrampen tot missies om de vrede te bewaren. Als communicatieadviseur vaart Leonoor van Poelgeest mee naar al die bestemmingen waar de Koninklijke Marine actief is. Waarom koos ze voor dit werk en wat heeft ze aan haar studie Bestuurskunde?

Dit was het programma van De Kennisboomgaard 2025:

The aims of the project are to: further clarify 'inhibition by safety'; explore and describe all possible sagety factors, with a special focus on the primary human safety source: social connectedness; reviewing prolonged stress responses without stressors.

Workshop

Corruption, integrity (or a lack thereof…) and public values are near omnipresent elements in public administration and politics of all times. Cases of corrupt public officials and politicians continuously emerge. Strangely enough, however, it often remains unknown what actually occurred, how something…

This thesis describes the synthesis, analysis of various tetrazine bearing compounds and use in bioorthogonal chemistry.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

Binnen de afdeling Civiel recht concentreert het onderzoek zich op de coherentie van het privaatrecht.

This proposed research uses ego-documents from visual artists that were not intended for publication to reassess the scholarly debate on the demise of the Russian Avant-garde aesthetic in the twenties and early thirties of the 20th century.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

Radio jets are important to the evoultion of galaxies. However, it is still not fully understood how a radio jet can be triggered.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

In this thesis, we developed new ways to use a technique called electroextraction (EE) to extract charged molecules from one liquid into another using an electric field.

Protoplanetary disks are the gas and dust environments where planetary systems form around young stars. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) this thesis analyses the gaseous molecular reservoir, using multiple tracers to resolve the 3D structure of protoplanetary…

Programma's die de symptomen van sociale angst bij kinderen willen verminderen, omvatten doorgaans meerdere onderdelen, zoals blootstelling en mentale herstructurering. Het is onbekend of afzonderlijke onderdelen positieve effecten opleveren bij kinderen of dat een combinatie van onderdelen nodig is…

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants.

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

The work in this thesis describes the fundamental role of Lkb1 as a conductor of metabolism-related processes in zebrafish larvae.

In this work the reconstruction of a tau neutrino signal in the KM3NeT detector is discussed.

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…

The work in this thesis has been focused on two subjects. The first is the assembly of alginate oligosaccharides and the generation of building blocks for the enzymatic synthesis of alginate, and the second is the total synthesis of large fragments of the zwitterionic SP1 polysaccharide.

This thesis studies operator-algebraic aspects of subproduct systems, a generalization of product systems of Hilbert spaces.
