Animal diet studies are critical for understanding ecological processes such as trophic interactions, energy flow, and nutrient cycling. By examining what animals consume, ecologists gain insights into species specialization, predator-prey relationships, and ecosystem management.

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

Humans and songbirds learn their vocalizations early in life by exposure to the vocalizations of adult conspecifics. Often, better learning outcomes are achieved with live, social, tutors than with audio-only exposure to vocalizations.

Human language is constantly evolving with its linguistic structure being shaped by language users at both individual and population levels. Focusing on the interplay between processes of language acquisition and communicative need in shaping human languages, this thesis introduces a novel computational…

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

Over the past two centuries, socioeconomic development has improved material living standards but has also intensified environmental pressures, including climate change and biodiversity loss.

Het onderzoek van de afdeling Economie is ondergebracht bij meerdere facultaire programma's. Het onderzoek van de afdeling richt zich thans met name op sociaal-economische vraagstukken, rechtseconomie en fiscale economie.

In the last decades, activity-based protein profiling (ABPP) has emerged as a powerful chemical tool that may aid the ever-challenging drug discovery process.

Binnen Quantum Leiden doen verschillende groepen onderzoek naar quantumnetwerken en quantumsensing.

Onlangs verscheen onder redactie van Luc Verhey en Gert Jan Geertjes een bundel over de constitutionele conventie bij Boom juridische uitgevers.

Hoe meer we leren over een (neuro-)psychologische of lichamelijke aandoening en de hieraan gerelateerde gedragsfactoren, hoe beter we deze niet alleen kunnen signaleren, maar ook behandelen. Het is dus belangrijk dat recente inzichten over (neuro-)psychologische problemen en daaraan gerelateerde gedragsfactoren…

This dissertation presents a new perspective on the life, work and character of the Dutch physical chemist Jacobus Henricus van ’t Hoff, first recipient of the Nobel Prize in Chemistry, and one of the most important and colourful scientists in Dutch history. The image of Van ’t Hoff that emerges from…

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.

Hydrogen peroxide (H2O2) is an important bulk chemical that is used in various industrial processes. More than 95% of the H2O2 used in industry is made via the anthraquinone process during which a large amount of energy is going to waste.

The clinical potential of applying synthetic lethality to cancer treatment is famously demonstrated by the BRCA1/PARP1 paradigm: a tumor specific defect in BRCA1 – a component of the DNA double-strand break (DSB) repair pathway homologous recombination (HR) – results in a remarkable sensitivity to PARP1…

Op 11 juni 2020 verdedigde Sabine Witting haar proefschrift 'Child Sexual Abuse in the Digital Era: Rethinking Legal Frameworks and Transnational Law Enforcement Collaboration'. Het promotieonderzoek is begeleid door promotoren prof.mr. J.J. Sloth-Nielsen en prof.dr.mr. S. van der Hof.

Glycoconjugate vaccines are composed of microbial poly- or oligosaccharides covalently linked to a carrier protein.

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

Leiden University College The Hague (LUC) biedt een 3-jarige bacheloropleiding aan waarin je je focust op Global Challenges; grote uitdagingen waar de mensheid mee te maken heeft: Vrede & Rechtvaardigheid, Diversiteit, Duurzaamheid en Welvaart.

Als een nieuwe methode is ontwikkeld om een (neuro-)psychologische aandoening of hieraan gerelateerde gedragsfactoren te herkennen en te behandelen, kan deze nog niet direct in de klinische praktijk worden ingezet. Eerst moet de methode geëvalueerd worden, bij voorkeur in gerandomiseerde, gecontroleerde…

Discovery and development of Central Nervous System (CNS) drugs is hampered by high attrition rates.

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

Mechanical metamaterials are man-made materials which derive their unusual properties from their structure rather than their composition.

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

Although plant domestication has significantly altered crop genetics and phenotypes, its effects on the taxonomic and functional diversity of plant-associated microbiomes are not well understood.

Metastasis is responsible for over 90% of cancer-related deaths and arises from the ability of a small subset of tumor cells to detach from the primary tumor, overcome multiple biochemical and mechanical barriers, disseminate through the body, and colonize distant organs.

The rapid expansion of research on human gut microbiome in recent decades has highlighted its role in human metabolism, immune regulation, and behavior.

We have examined sequences from the ligand-binding domain of the nicotinic acetyl choline receptor (nAChR) in 148 vertebrate species. We are in interested in this receptor because the α-neurotoxins of many venomous snakes binds to this receptor in its location at the neuromuscular junction in all ve…
