The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

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…

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

The increasing resistance of pathogenic bacteria to antibiotics necessitates the discovery of new medicines.

Dit artikel levert een bijdrage aan een groeiend aantal onderzoeken naar radicalisering. Het richt zich specifiek op het onderscheid tussen individuen die radicalisering en daardoor betrokken raken bij terroristisch geweld en individuen die radicaliseren maar niet betrokken raken bij geweld.

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

Op 2 juli promoveert Jiaqi Wang. Het Leiden University Centre for Linguistics feliciteert Jiaqi!

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

Op 30 september 2021 verdedigde Babette van Hazebroek haar proefschrift 'Understanding delinquent development from childhood into early adulthood in early onset offenders'. Het promotieonderzoek is begeleid door promotoren prof.dr. J.W. de Keijser en prof. dr. A. Popma (VUMC).

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

This study seeks to analyse how job stress could be the result of performing administrative tasks

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

This thesis explores how electron paramagnetic resonance (EPR) spectroscopy can be used to investigate key biochemical processes.

Jaroslaw Kantorowicz and Rok Spruk onderzoeken de bijdrage van institutionele hervormingen aan economische groei.

In deze publicatie worden problemen met betrekking tot de grensoverschrijdende afwikkeling van financiële instellingen onderzocht.

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

Religion and ethnicity are inextricably linked in discourse within and about Central Asia. One common narrative suggests that as a result of differences between historically sedentary and nomadic populations, ethnic Tajiks and Uzbeks are naturally more religious and more likely to radicalise than their…

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

The thesis explores micromammal fossils from the Afşar section in Anatolia, a crucial locality for understanding the Pliocene epoch and the transition to the Villafranchian Age.

In september 2024 lanceert het Europa Instituut van de Universiteit Leiden het nieuwe Engelstalige masterprogramma Governance of Migration and Diversity [GMD, betekent ‘Migratie en Diversiteitsbestuur’]. Programmacoördinator Moritz Jesse: 'We kunnen juristen met grondige kennis van de historische, sociologische…

Waarom kozen sommige Euraziërs ervoor in de voormalige kolonie te blijven, terwijl anderen naar de metropool of een ander land vertrokken?

Het is nog lastig in te schatten wat de gevolgen zijn van de aangekondigde bezuinigingen. Een week na Prinsjesdag kan decaan Koen Caminada al wel wat vragen van binnen FGGA beantwoorden. ‘We staan er relatief goed voor, maar de gevolgen kunnen groot zijn.’

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

In Rotterdam woont een grote groep Kaapverdiaanse migranten. Promovendus Seger Kersbergen deed onderzoek naar deze ‘stille minderheid’ en vertelde hierover aan NRC.

De master Governance of Migration and Diversity is uitbreid met een juridische track (LL.M.). Vanaf nu kunnen ook rechtenstudenten zich inschrijven voor deze master, terwijl studenten uit de andere richtingen nu kennis kunnen maken met het juridische perspectief.

De Erasmus Universiteit Rotterdam, Universiteit Leiden en de TU Delft hebben het initiatief genomen voor een nieuwe master (subtrack) Governance of Migration and Diversity. De interuniversitaire master start per september 2016.

Dit project identificeert en beschrijft de belangrijkste Indo-Europese talen en taaltakken en heeft tot dusver geresulteerd in twaalf delen, gepubliceerd als The Leiden Indo-European Etymological Dictionary Series (Brill, Leiden).
