In this article, Vanessa Newby, assistant professor at the Institute of Security and Global Affairs, discusses credibility in peace operations. This article argues that credibility in peace operations must be built for both deterrence and cooperation purposes.

We consider the propagation of electrical signals through nerve fibres.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

PURPOSE: In the present study we investigated the root-cause of an interference signal (100-200 nm) of sugar-containing solutions in dynamic light scattering (DLS) and nanoparticle tracking analysis (NTA) and its consequences for the analysis of particles in biopharmaceutical drug products.

What are the precise identities, possibilities and current practice examples of the various time frames in music and what bearings do they have individually and in combinations on the speed of the music?

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

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

Developing new methods for performing improvised music

Mechanobiology is a major area in biology, however, mechanics is currently a missing element in drug development pipelines. This has led to a high cost for the society. Mechanotoxicity of drugs often appears as a long-term side effect of drugs, and has led to removal of drugs from the market. Furthermore,…

The goal of this study is to systematically investigate how intonation (speech melody) is conveyed in whispered speech.

Does Artifical Light at Night (ALAN) disrupt seasonal physiological and behavioral patterns in migrating freshwater fish?

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

On the 11th of January, Rasmus Puggaard-Rode successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Rasmus on this achievement!

In this research group, headed by Bob Van de Water, cell signaling programs that underlie adverse drug reactions as well as cancer development and progression are unraveled. Adverse drug reactions involve cell injury in critical target organ cells which leads to the activation of cellular stress response…

Behavioural biologist Wouter Halfwerk has been awarded a 2-year outgoing Rubicon-grant from NWO. He will be working at the Smithsonian Tropical Research Institute with bats and frogs to understand the evolution of multimodal communication.

Mashaghi lab conducts research at the interface of physics, engineering and biomedicine. We develop and use theoretical and experimental approaches to address basic and applied research problems.

Physics and Engineering Approaches to Biomedicine and Pharmacology

This dissertation provides a formal description of the relationship between diatopic/diachronic micro-variation and phonologization through analysis of the phonetic/phonological properties of unstressed vowel reduction and vowel insertion in two Northern Italian dialects.

This project examines how speakers store and process regular pitch variation.

This study investigates the perception and production of emotional prosody by native and non-native listeners and speakers, i.e. Chinese and Dutch listeners and speakers, including Dutch L2 learners of Chinese.

How do we process language and speech? How do we integrate information at different levels – intonation, sentence structure, meaning, tone, words, sounds - and how does information at one level interact with information at another level?

Industrial ecologists Stefano Cucurachi and Flora Siebler are part of the new consortium PROGENY, which received 3.6 million euros from the European Commission. PROGENY is an exciting project that will study the possibilities of soap films for innovations, such as ultra-thin screens.

All languages use melody in speech, primarily via rises and falls of the pitch of voice. Such pitch variation is pervasive, offering a wide spectrum of nuance to sentences – an additional layer of meaning. For example, saying “yes” with a rising pitch implies a question (rather than an affirmation).…

We focus on a better understanding of the mechanisms of cancer drug resistance and metastasis.

In this article, Thijs van Dooremalen and Philip Smith investigate how public discourse of heatwaves have shifted in British newspaper discourse, drawing on Raymond Williams’s theory of dominant, emergent, and residual cultural patterns to analyse changes in language and interpretation over recent d…

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

Prostate cancer (PCa) is one of the most prevalent cancer in males.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

To increase clinical success rate of drugs, a better understanding of drug action mechanism and disease dynamics is required. Metabolomics, which studies small molecules involved in biochemical processes in organisms, has shown to be a useful tool for this better understanding.

Stimulating the vagus nerve, which provides a direct link between the gut and brain, makes people pay less attention to sad facial expressions. This research study by psychologists Katerina Johnson and Laura Steenbergen is published in the journal Neuroscience, and made it to the cover.

The Co-Align Conference 2023 will be held on 16 May 2023 at Leiden University.

The experiments described in this thesis employ local lentiviral knockdowns in brain areas of female zebra finches followed by behavioural assays consisting of preference and Go/Nogo tasks.

This thesis describes the development and optimization of the first molecular tools to study the enzyme PLA2G4E.

Animal Sciences’ contributions to the Host-Microbe Interactions research theme focus on the interaction of animal hosts with pathogenic microbes but also the beneficial role of the gut microbiome.

The recent reciprocal expulsions of ambassadors between Spain and Nicaragua are not merely political gestures but legally structured acts grounded in the framework of the Vienna Convention on Diplomatic Relations (1961) (VCDR). The episode illustrates how the persona non grata mechanism - a classical…
