Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

Programma directeur van het bachelorprogramma Security Studies Daan Weggemans trapte vanmiddag het eerste webinar voor studiekiezers af. In Kaltura Live had hij een internationaal publiek van zo’n 60 geïnteresseerden.

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…

The adsorption of D2 and CO2 on catalyst surfaces is studied using a molecular beam in ultra-high vacuum.

In this thesis, two potential therapeutic targets for diabetic nephropathy were dentified and investigated. First, we show that glomerular clusterin is upregulated in diabetic nephropathy and demonstrated that recombinant clusterin protein can protect the podocytes against oxidative stress in vitro.…

De Nederlandse krijgsmacht is de afgelopen jaren op vele fronten veranderd. Letterlijk en figuurlijk. Deze uitgave brengt de laatste kennis en inzichten over het functioneren van dit belangrijke instituut bijeen. Een handboek voor praktijk, wetenschap en onderwijs.

The electrochemical hydrogenation reaction is an alternative approach for the transformation of unsaturated bonds without the use of flammable dihydrogen gas.

Op vrijdag 29 augustus 2025 ontvingen 370 studenten hun bachelordiploma International Studies. De diploma's werden uitgereikt in de historische ambiance van de Pieterskerk in Leiden. Familieleden, vrienden en medewerkers waren toegestroomd om deze heuglijke gebeurtenis met de afgestudeerden te vieren…

Op vrijdag 11 december 2020 vond het eindejaarsseminar van Empirical Legal Studies plaats, uiteraard geheel coronaproof online. Via dit seminar konden collega’s en andere geïnteresseerden op een laagdrempelige manier meer te weten komen over het toepassen van empirische onderzoeksmethoden in de rec…

Ana Oleart kwam van Barcelona naar Den Haag voor haar bachelor International Studies. Na maar liefst twee masters aan de Universiteit Leiden werkt ze nu op de HR-afdeling van een grote hotelketen.

On Monday 26 August, students were warmly welcomed at the Wijnhaven location with a blue carpet and live music. Accompanied by their friends and family, they gathered to receive their BSc Security Studies diploma.

‘Religie is overal’ – dat is de eerste zin uit de missie van het nieuwe Leiden University Centre for the Study of Religion (LUCSoR). Na intensieve voorbereiding en in nauwe samenwerking met het Leiden University Institute for Area Studies (LIAS), is LUCSoR vandaag van start gegaan. Dit nieuwe centrum…

Dit onderzoek gaat over de vormen, functies, betekenissen, en sociaal-culturele waarden die in Palenda besloten liggen, met als doel te begrijpen hoe dit concept via metaforen de wereldbeschouwing van de Muna-volk (Mieno Wuna) weerspiegelt en vormgeeft.

The book ‘Bestrijdingsmiddelen en Milieu' gives a transparent overview of facts and figures concerning pesticide use in the Netherlands and the impact of pesticides on the environment.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

Global healthcare is on the verge of an antibiotic availability crisis as bacteria have evolved resistance to nearly all known antibacterials. Identifying new antibiotics that operate via novel modes-of-action is therefore of high priority.

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

β-Lactamases are enzymes that can break down β-lactam substrates, such as antibiotics, preventing the use of these antibiotics for the treatment of various infectious diseases. However, some compounds, β-lactamase inhibitors, can block these enzymes allowing for possible treatments using a combination…

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

The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

The lysosomal β-glucosidase named glucocerebrosidase (GCase) is a retaining β-glucosidase that hydrolyzes the glycosphingolipid glucosylceramide (GlcCer) to ceramide and glucose at acid pH.

Polymyxins are clinically used antibiotics, discovered in mid-20th century. Once abandoned due to excessive nephrotoxicity, they are now used increasingly to address infections caused by multi-drug resistant Gram-negative bacteria.In this thesis, we describe the development and synthesis of analogues…

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

Enzymes are innately sensitive to changes in the amino acid sequence, which largely constrains their evolutionary potential, i.e., evolvability. This evolutionary burden can be alleviated in the presence of stabilizing mutations, which increase the buffering capacity of enzymes to tolerate mutations…
