The small quantum world and our world of perception obey different laws of nature. Leiden physicists search for the border between both worlds. In an article published soon in Physical Review Letters they set an upper limit.

Due to their central physiological roles in living organisms, retaining beta-glycosidases have been the subject of tremendous research efforts to examine their structure/function relation using numerous biophysical and biochemical approaches.

Pericytes, the mural cells of blood microvessels, are important regulators of vascular morphogenesis and function that have been postulated to mechanically control microvascular diameter through as yet unknown mechanisms.

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

In this thesis, we focus on novel proteins/mechanisms that regulate integrin-adhesion mediated mechano-transduction.

Our group explores the larger domain of quantum measurement. In particular we investigate two themes that are closely connected: The detection of specially prepared quantum states of light and understanding and characterizing quantum photon detectors.

The aim of our research program is to better understand the etiology and course of mood, anxiety and stress-related disorders, such as depression and posttraumatic stress disorder (PTSD). We investigate both the transdiagnostic mechanisms underlying these disorders and work on improving the treatments…

On Thursday 9 november, Reijer Passchier defended his dissertation 'Informal constitutional change'. His supervisor is Professor Wim Voermans.

Our research examines mental health risk and resilience in young people. We do so by integrating cultural, social, cognitive and neurobiological factors and their interactions.

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

Glycosidases (GHs) are enzymes responsible for the degradation of carbohydrates and play many roles in human health and pathophysiology. Often, abnormal levels of glycosidase activity are markedly linked to human pathologies.

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.

Children with autism spectrum disorder experience serious challenges in social functioning, which threatens their development in many areas of functioning.

The symposium is open to all registered participants and consists of a one-day programme and a poster session.

This article devises a framework to assess the degree to which human rights bodies provide duplicating or contradicting recommendations to States. Focusing on the case of torture, it creates an original database of recommendations delivered to 14 countries in the years 2012–2016. Results show that duplications…

During the early modern period, many medieval manuscripts were cut up into strips of parchment which were reused to reinforce the bindings of newly printed books. Until recently, these reused pieces of medieval manuscripts only came to light when the early modern book binding was damaged and/or subjected…

If you replace the standard hydrogen atoms in ice with a heavier variant, something odd happens. The volume occupied by the molecules increases by 0.1 per cent. Leiden chemist Jörg Meyer and his colleagues have created a theoretical model that describes this behaviour. Their research appeared on the…

How do plant defense genes get activated?

Which adolescents are more at risk of developing social anxiety disorder later in life?

In Quantum mechanics, particles can be in multiple positions simultaneously. Yet, when a measurement is made, the particle is found only in one place. Technology has come to a point where we may design experiments that will tell us how.

The effects of many treatments are determined, to a significant degree, by factors other than the medicine or treatment itself. For example, placebo effects can be equal to the effect size of for example antidepressants or painkillers. Contributing factors are the trust placed in the doctor, the expectation…

Open online education has become a highly popular method of education. The current project aims to further our knowledge of how open online courses can be best designed to be consistent with human learning mechanics and facilitate meaningful learning.

Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.

Research in the group Clinical Neurodevelopmental Sciences is focused on understanding and influencing developmental mechanisms in children and adolescents.

Miriam Cohen defended her PhD dissertation entitled “Reparations for International Crimes and the development of a Civil Dimension of International Criminal Justice” on 28 June 2017. She wrote her thesis under the supervision of Professor L.J. van den Herik and Professor C. Stahn.

In this research group, headed by Prof. Erik Danen, the aim is to unravel cellular signaling mechanisms in normal and diseased cells, with a long-standing interest in cell adhesion signaling. In complex multicellular organisms such as ourselves, a division of labor emerges where different tissues and…

This doctoral thesis is an effort to understand how lipid phase-separation induced by diacylglycerol analogues in lipid-based nanoparticles affects their in vivo behavior, leading to specific nanoparticle-protein communications and selective cell targeting.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

Aluminium-based adjuvants, such as aluminium hydroxide and aluminium phosphate, are well-known for their immune-stimulating properties.

To what extent does the Law Ombudsperson for Children achieve its goals as intended by the legislator when introducing the law?

Anne Meeussen is the winner of the Fysica 2020 Young Speakers' Contest. She was elected by the online attendants after delivering a talk about metamaterials.

Somatic symptoms, such as pain, itch, and fatigue have been shown to have a bidirectional relationship with mental symptoms. Although acute somatic symptoms serve some adaptive properties, chronic symptoms can instead lead to interference in daily activities and lower quality of life.
