This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

Supply risks are not new. But the aggravation of power conflicts on the international stage coupled with global shifts towards energy transition and digitalization has triggered the next supply risk research era.

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

Dit project beoogt de ontwikkeling van geavanceerde data-analysemethoden voor monitoring en het vergroten van ons inzicht in de dynamiek van de biodiversiteit in natuurgebieden zoals de Oostvaardersplassen.

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.

Ooit was de spoorlijn van Kimberley naar Kambove in zuidelijk Afrika een teken van welvaart en vooruitgang. Inmiddels kenmerken de uitgeputte mijnsteden zich door verval en vervuiling. Hoogleraar Jan-Bart Gewald ontvangt een NWO L-beurs om te onderzoeken wat de langetermijngevolgen voor de wereld zi…

Arco Timmermans, bijzonder Hoogleraar Public Affairs aan het Instituut Bestuurskunde van de Universiteit Leiden, werd door Radio EenVandaag uitgenodigd om samen met Mark van Baal van Follow This te spreken over de invloed die een miljardenbedrijf als Shell op de buitenwereld heeft.

GLOBOX is a spatially differentiated multimedia fate, exposure and effect model. It is used for the calculation of spatially differentiated LCA characterisation factors on a global scale.

‘We moeten op zoek naar producten die gewone wegwerpplastics kunnen vervangen, bijvoorbeeld van plantmateriaal. Binnen een jaar of 20 is het gemiddelde plasticgebruik van een huishouden met grote slagen verminderd.’ Volgens Thijs Bosker, Universitair Hoofddocent aan het Leiden University College, in…

Steden, Voedsel, Water, Biodiversiteit, Bronnen en Energie: dit zijn de belangrijkste onderzoeksthema’s voor het CML. Ons doel is altijd om wereldwijd voorop te lopen in ons vakgebied. En echte impact te hebben met onze onderzoeksprogramma’s.

Van waterzuiveringsinstallaties tot een lekkere warme douche, de CO2-uitstoot ten gevolge van het watergebruik in de VS staat gelijk aan dat van 50 miljoen auto’s die een jaar lang rondrijden. In The Washington Post raadpleegt journalist Tik Root verschillende experts om te leren over manieren om ons…

To contribute to the body of knowledge aiming at a better coverage of ecosystem service assessment in LCA studies, this thesis dives into the challenges of incorporating existing ecosystem service methods within the impact assessment phase of the conventional LCA framework.

At the moment, over 350.000 chemicals are registered worldwide for production and use. Their application, however, may harm human health and the environment.

The field of science communication is very broad. Below is a list of organisations where SCS students can fulfill internships or where alumni have found jobs.

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

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.

The main research question of this thesis was: Can nitrogen cycling on dairy farms on peat soil in the Dutch Green Heart area be improved by adapting management to the nitrogen supply from soil and by using other grassland species and crops without affecting milk production?

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

Consequences for sediment stability and seston trapping

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.
