A research into for whom, when and why the Cool Little Kids intervention works.

Developmental considerations in the design and delivery of cognitive-behavioural therapy for adolescent school refusal

In this thesis, the discovery and optimization is described of chemical tools to study the N-acylethanolamine (NAE) biosynthetic pathway.

Cynthia van Vonno, political scientist at Leiden University, explains why individual MPs vote according to the party group line.

The major aim is to develop, evaluate, and implement disease-generic cognitive-behavioral interventions through the internet in order to optimize tailored health care for patients with chronic somatic conditions.

Professor P.F. (Paul) Wouters has been appointed dean of the Faculty of Social and Behavioural Sciences with effect from 1 January 2019. Wouters has been appointed for a period of three years and succeeds Professor Hanna Swaab, whose second term of office as dean expires this year. Swaab will remain…

It is sufficiently plausible that the professor from the Faculty of Archaeology exhibited the ‘inappropriate and unacceptable behaviour’ detailed in the advice of the investigating committee. That is is unless the professor provides counter-evidence. This is the conclusion of the Subdistrict Court…

‘Make more room for nature on farmland and you'll be surprised at the result.' This was the advice from Geert de Snoo in his Dies lecture.

A professor from Leiden University, together with a former employee (who is also the professor’s partner), has been guilty of long-term unacceptable and often transgressive behaviour in the form of abuse of power and manipulation. This behaviour led to a culture of fear among staff who were largely…

A research into how people eat and drink during their daily routines, and the circumstances under which these activities take place.

ADHD&me is a new cognitive-behavioural therapeutic intervention for young adults (16–25 years old) with ADHD, specifically aimed at improving self-esteem. In this study, we are conducting a Randomized Controlled Trial (RCT) to examine whether this intervention improves self-esteem and whether related…

This article by Danielle Goldwert, Sara Constantino, Jaroslaw Kantorowicz and colleagues presents one of the largest behavioral 'megastudies' to date, testing how different interventions can stimulate public, political and financial climate advocacy.

The electrochemical reduction of a group of organic compounds on platinum is strongly dependent on the arrangement of the atoms in the platinum surface. Christoph Bondue, postdoc in Marc Koper's group, published this in Nature Catalysis on 4 March. The reduction of such compounds is an important process…

In the thesis the dynamics of strategies is studied from two perspectives.In the first part of the thesis strategies are considered to be opinions present in a community.

Short description about 20th anniversary of CEDC, the fieldstation in Cameroon, and 20 years of cooperation between Leiden University with the University of Dschang in Cameroon.

Explaining your PhD research to others can be quite difficult, especially without talking! PhD student Annebelle Kok of the Institute of Biology Leiden was one of the finalists of the 'Dance Your PhD' competition of scientific journal Science. ‘You have to understand your own research well if you are…

This thesis explored the molecular pharmacological mechanisms of targeting CB2R via investigation of novel drug discovery concepts such as target binding kinetics, allosteric modulation and biased signaling.

Actinobacteria are Gram-positive bacteria that have a complex multicellular life cycle and are well known for their ability to produce a wide range of bioactive natural products (NPs).

The Institute of Biology Leiden (IBL) is an internationally oriented institute for research and education in biology. We are part of the Faculty of Science at Leiden University.

On the 15th of April, Shaoyu Wang successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Shaoyu on this achievement!

Young people tend to take more risks than children or adults. This trend is related to the reward centre in the brain, which is much more active when they are rewarded, PhD candidate Barbara Braams discovered. Personality, testosterone levels and social context also play a role in risk-taking.

Fishes rely heavily on sound to find their way during migration or dispersal. Many species are affected by noise pollution. Hans Slabbekoorn from the Institute of Biology Leiden received a HORIZON2020 grant of 500,000 euros to study the impact of sound conditions on movement decisions of fishes.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

Merijn de Bakker and colleagues of the IBL-research group of Prof. Mike Richardson provide a unique view on digit evolution in crocodiles and birds in their recent study published in Nature.

Peer-mentored cognitive behavioral therapy for adolescents with mild intellectual disability and anxiety disorder

Biologists today have to be able to work with big data. Data analysis skills should be taught from the start of the degree programme, or - even better - in secondary school. This is the message of Vera van Noort, new Professor of Computational Biology. Inaugural lecture 22 January.

Does the sitter have agency in the making of a photographic portrait? And if so how?
