In this research note, Van der Does & Kantorowicz aruge that citizens that tend to experience political exclusion are often more supportive of direct and participatory forms of decision-making.

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

Composer Paul Craenen (1972) is actually a pianist, but as part of his PhD ceremony, he performed a composition on PVC pipes. Craenen studies the position and role of the body in music. ‘I am interested in what precedes the resulting sound’.

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

On the 2nd of July, Jiaqi Wang successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Jiaqi on this achievement!

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

Ludo Block wrote the eleventh chapter of the book 'Post-Crimea Shift in EU-Russia Relations: From Fostering Interdependence to Managing Vulnerabilities'. His chapter 'Business as Usual? Police Cooperation under a Cloud of Political Animosity' can be found on page 204 of the book.

From as early as classical antiquity there has been an interplay between literature and medicine.

In this thesis, we present new laboratory data of interstellar dust analogues.

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

The sixth issue of Ex Novo explores how ‘peripheral’ regions currently approach both the practice and theory of public archaeology placing particular emphasis on usually underrepresented regions of Eastern and Central Europe, the Mediterranean and beyond.

Interview with political scientist Hans Vollaard (Leiden University) about “Nexit” speculations, the strengths and weaknesses of Geert Wilders’s Party for Freedom, and the general attitude towards Europe in the Netherlands.

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

In this article, Kuipers and Timmermans analyze the first lady's relationship with policy problems in the period 1945-2013.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

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

Leiden-Yale collaboration uncovers a tale of samurai same-sex love in a library manuscript.

The CC chemokine receptor 2 (CCR2), a member of the G protein-coupled receptor (GPCR) superfamily, is widely involved in autoimmune and inflammatory diseases. However, no drugs for this receptor have made it to the pharmaceutical market yet.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

Squatters and autonomous movements have been in the forefront of radical politics in Europe for nearly a half-century—from struggles against urban renewal and gentrification, to large-scale peace and environmental campaigns, to spearheading the antiausterity protests sweeping the continent.

Shining a light on the nefarious netherworlds of espionage, this is the first book to concentrate on the actual techniques and technologies used by early modern spies —from ciphers to counterfeiting, invisible inks to assassination

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

On 30 September 2021 Babette van Hazebroek defended her thesis 'Understanding delinquent development from childhood into early adulthood in early onset offenders'. The doctoral research was supervised by Prof. J.W. de Keijser and Prof. A. Popma (VUMC).

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

Despite an increased EU role in the preparedness, monitoring and coordination of health emergencies over the past two decades, Member States’ responses to the first wave of COVID-19 were surprisingly uncoordinated. In light of calls to improve cooperation regarding future health emergencies, this article…

This thesis explores how electron paramagnetic resonance (EPR) spectroscopy can be used to investigate key biochemical processes.

How do educational philosophies, discourses and practices spread around the globe, and how are they transformed and adapted locally?

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

In a new study, we found that when we are exposed to potential harm to the other person, it improves our automatic attentional processes to avoid harm to that person.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

Ramesh Ganohariti will examine legal identity in three post-Soviet aspirant states and outline four common scenarios in this article.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

Across many decision-making tasks, people and animals systematically repeat (or alternate) their choices - even when the choices they make are intrinsically uncorrelated. This phenomenon (also known as 'sequential effect' or 'choice hysteresis') has been known for at least a century, and may be a stable…
