Dividing Worlds: Tsunamis, Seawalls, and Ontological Politics in Northeast Japan

In Indigenous Ancestors and Healing Landscapes Jana Pešoutová presents new interpretations of current healing practices in Cuba and the Dominican Republic juxtaposed against the European colonization of the Caribbean after 1492.

The narrow but long stretched stript of Frisian land along the North Sea was already occupied before Roman times. However, man repeatedly suffered setbacks when he tried to extend his living space, both in the tidal marshes and the peat area south of them.

Marc Koper’s research focuses on electrocatalysis and electrochemical surface science for sustainable energy and chemistry. Reactions of interest are the redox reactions of the oxygen/hydrogen cycle (water oxidation, hydrogen evolution), the carbon cycle (reduction of carbon dioxide, oxidation of small…

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

Cardiovascular diseases (CVDs) are the leading global cause of mortality. Endothelial dysfunction, an early reversible stage of CVD development, is marked by decreased nitric oxide production linked to Ca2+ influx in endothelial cells.

The mechanism of the electrochemical reduction of dioxygen by a mononuclear pyridylalkylamine copper complex was investigated (see picture). It was shown that in neutral aqueous solution dioxygen undergoes stepwise reduction, wherein hydrogen peroxide plays a key role. The rate constants determined…

The authors in this volume explore how external innovations (products, technologies, services, institutions and processes) have been appropriated in African societies in order to be acceptable and relevant to local conditions, expectations and demands.

The effectiveness of the skin barrier underlies the outer layer of the skin: the stratum corneum (SC). However, in several skin diseases this barrier is impaired. In two inflammatory skin diseases, atopic eczema and Netherton syndrome, an increased level of monounsaturated fatty acids (MUFAs) has been…

Dissolving microneedles are a subgroup of microneedle types that completely dissolve within the skin. During this dissolving process the vaccine, stored in the needle matrix, is released into the skin.

The idea of global governance and trust in international institutions are apparently getting into deep water. But is there a legitimacy crisis? Not according to international élites, as Jan Aart Scholte (Leiden University), Soetkin Verhaegen (Maastricht University) and Jonas Tallberg (Stockholm University)…

Planets are formed in disks of gas and dust around young stars.

Since 2006, HJD has made an important contribution to shaping diplomatic studies as an international academic field. Our new HJD Diplomacy Reading List presents a diverse collection of analyses categorized into forty-five topics published in HJD over the years. We hope these lists prove a valuable resource…

Generations of Leiden students and academics have done archaeological research into the early medieval history of Oegstgeest. This makes this old settlement one of the best-documented sites from that era. In a new book, Leiden researchers take stock.

Measurement of brain activity by external electrodes (EEG).

Archaeological heritage management is concerned with the identification, protection, management and preservation of the material remains of human activity in the past (of whatever period and in whichever region of the world) and with the interaction that this involves with all kinds of stakeholders.

This dissertation explores various perspectives on the term immersion, and its relation with, and transformation through, a composer’s practice.

High resolution altitude data created by airborne LiDAR allow the investigation of large areas and often inaccessible tracts of land and has the potential to reveal undiscovered archaeological heritage.

The department of World Archaeology combines research and education about regions all over the world, from Human Origins to the Middle Ages, and from Europe, to Asia, Africa and the America’s. That broad range in time and space makes the department a dynamic pluriform community with many different approaches,…

Just as in phase 1, phase 2 of the Gorlaeus Building will focus on sustainable building.

A radical reduction in the amount of meat, dairy and other products sourced from animals is possible in the coming decades, as people turn to an increasing variety of alternatives. This would unlock vast amounts of land that we could use to produce energy and remove carbon from the atmosphere. Leiden…

The sustainable production of hydrogen could potentially be made more efficient by adding a cleverly chosen salt to the process. Researchers at the Leiden Institute of Chemistry (LIC), in collaboration with physicists at the University of Twente, have discovered that the type of salt present in the…

The latest research from the Leiden outdoor laboratory ‘Living Lab’ shows that the insecticide thiacloprid strongly influences even the most common and robust dragonfly species in the Netherlands. The study was published in the Journal of Applied Ecology.

Following the Beirut explosion, BBC's podcast series The Foodchain explores the chemical that caused the blast: ammonium nitrate. A compound that is widely used to produce fertilizer. Professor of Environmental sustaibability Jan Willem Erisman tells about the effects of nitrogen on the environment.

How do we know what a quantum computer is good for when it hasn't been built yet? That's what PhD candidate Casper Gyurik investigated by combining two terms you often hear: quantum computing and machine learning.
