Why do communities form militias to defend themselves against violence during civil war? Using original interviews with former combatants and civilians and archival material from extensive fieldwork in Mozambique, Corinna Jentzsch (Leiden University Institute of Political Science) explains the timing,…

During the development of the (human) body from a single fertilized egg, organs and structures must form. The development and growth of biological forms is called morphogenesis.

It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

The recently published book ‘Avian Cognition’ is the first multi-author book to provide a comprehensive treatment of the cognitive abilities of birds and how they compare to those of other animals. Carel ten Cate, professor of animal behavior at the Institute of Biology, and Susan D. Healy (StAndrews…

This study presents the findings of a laboratory-based experiment testing hypothesised processes implicated in the prevention of violent radicalisation through counter-narratives. The central aims of the study were to contribute to counter-narrative theory, whilst highlighting the value of experimental…

Morality, mathematics, geometry, geography, music, navigation, and language are traditionally viewed as uniquely human cultural achievements and abilities. The study of their development and variation is classified as part of the humanities and social sciences. These fields have been mainly studied…

The purpose of this study was to investigate the formation and growth kinetics of complexes between proteins and oppositely charged polyelectrolytes.

Fred Janssen is curious about how best to teach students and students to gain a good understanding of complex ‘swamp situations’. This is the subject of his inaugural lecture as Professor of Science Education at the ICLON and the Faculty of Science. Inaugural address 19 June 2017.

The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.

On 4 and 5 November 2021 an ICOG-workshop will be held on the cognitive turn in history. It is possible to attend this workshop online. The participants of the workshop are cultural and intellectual historians of the pre-modern periods and/or of the historiography of academia from a long-term perspective,…

In September 2019, Manon Mulckhuyse will start a position as assistant professor in the Cognitive Psychology Unit.

This thesis aimed to investigate core cross-linked polymeric micelles (CCPMs) and expand their potential for the delivery of hydrophobic drugs and co-factors.

Which molecules go into forming planets? PhD candidate Christian Eistrup and his colleagues have created new models to research this question. Their findings could change our idea of which molecules were forming Jupiter or even Earth.

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…

Protoplanetary disks are the gas and dust environments where planetary systems form around young stars. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) this thesis analyses the gaseous molecular reservoir, using multiple tracers to resolve the 3D structure of protoplanetary…

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…

Kyra van der Moezel defended her thesis on 7 September 2016.

Together with two other authors, Jaroslaw Kantorowicz from ISGA investigates the susceptibility to believing in misinformation.

From 5 to 7 June, the conference "The Senses, Cognition, and the Body in Medieval Devotional Practices" will take place at the University of Padova. The conference programme can be found below. The conference can be attended virtually through the registration link below.

Which intervention technique is more effective in reducing public speaking anxiety in children aged 9 – 12 years, exposure or restructuring cognitions?

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star at which planet formation has finished, while the same-aged companion star still has a planet-forming disk. The researchers…

In his report, Dutch cabinet negotiator Kim Putters proposes the formation of a ‘programme cabinet’ and an outline agreement. The four political parties involved have agreed on this form of cabinet, and Putters therefore appears to have succeeded in his mission. Wim Voermans, Professor of Constitutional…

The Palaeolithic period extends from the earliest stone tools (and in Europe, earliest occupation) to the beginning of the current warm period.

Those pesky raindrops that get you wet on your way to work, are formed high up in the sky from clouds of water vapour. The process of nucleation describes the way this happens. Edgar Blokhuis of the Leiden Institute of Chemistry developed a theory to describe this transition more precisely. Chemists…
