When a star is born in our Galaxy, it is quite likely that it has formed within a massive cluster, which hosts numerous high-mass stars bathing their lower mass neighbours in UV radiation.

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…

Vanaf 1960 hielp de Nederlander Albert Winsemius de stadstaat Singapore om versneld uit de economische misère te komen. Dat deed hij onder meer door Singapore voor te houden hoe Nederland zich na de oorlog, gesteund door de Amerikaanse Marshallhulp, snel zich weer oprichtte. Promotie op 19 november.

EU Universe Awareness (EU-UNAWE), een educatief sterrenkundeproject van de Leidse Sterrewacht, heeft gloednieuw lesmateriaal ontwikkeld: Universe in a Box.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

In dit artikel leveren Bert Fraussen en Valérie Pattyn een theoretische bijdrage aan de bestaande literatuur over beleidsadvies door zich te laten inspireren door de nichetheorie.

Centraal in dit proefschrift staat de idee dat jongeren het recht hebben betrokken te worden bij besluitvormingsprocessen over zaken die hen aangaan, zoals hun schoolopleiding, en dat jongeren serieus dienen te worden genomen in hun opvattingen en suggesties over deze zaken.

Freya Baetens is momenteel gastprofessor aan de National University Singapore (NUS). NUS begon als een medische faculteit in 1905, opgericht door een vastbesloten groep van zakenlui onder leiding van Tan Jiak Kim, om aan de noden van de lokale bevolking tegemoet te komen. Vandaag is NUS het academische…

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

De Amerikaanse president Donald Trump is al aangekomen in Singapore waar de nucleaire top plaatsvindt. Hij zal in gesprek gaan met de Noord-Koreaanse leider Kim Jong-un. Maar wat kunnen we eigenlijk verwachten van deze historische gebeurtenis? RTL Nieuws sprak met Remco Breuker, hoogleraar Koreastudies…

This thesis aims to investigate the effect of tripartite interaction between microbial inoculants, the plant, and herbivore insects on the rhizosphere microbiome and volatilome. We investigated the rhizosphere microbiome and volatilome of tomato plants exposed to insect herbivory and/or inoculated with…

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

Op vrijdag 13 en zaterdag 14 september 2024 vond de jaarlijkse bijeenkomst van de European Group of Public Law (EGPL) plaats in Legrena, Griekenland.

Given the accelerating appearance of antimicrobial resistance, there is an urgent need for more fundamental research into novel antibiotic strategies. The work in this thesis helps to address this global problem by developing new antibiotic compounds, inspired by the antibacterial mechanisms of the…

In the past decade many population studies have been performed with the Atacama Large Millimeter/submillimeter Array (ALMA) to understand the bulk properties of protoplanetary disks around young stars. These population studies mostly consisted of low mass stars, with relatively few of the disks around…

Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

As a member of the Research School you can take part in join-in courses. Join-in courses are MA-courses in medieval topics given in set MA-programs of the six participant universities of the Research School. These courses allow you to further specialize in certain topics.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

In this thesis the combinatorial use of bioorthogonal labelling and Electron Microscopy (EM)-based imaging techniques is explored to enable observations of specific molecular targets in their ultrastructural context within the cell.

Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…
