A combination of two potential drugs gives hope of a 'super blockage' of an over-active immune system, Leiden researchers report in Nature. The breakthrough came from the crystallisation of a membrane protein.

Bringing together institutes and research groups, how do you do that? The Faculty of Science set up a joint research theme and financed three PhD positions. After four years, the profiling programme Endocannabinoids expires. ‘It really brought us together, and the collaborations remain.’

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

This thesis investigates the processing of words written in Japanese kanji and Chinese hànzì, i.e. logographic scripts.

Let A be a commutative algebraic group over a field K, and let G be a finitely generated subgroup of the K-rational points of A. The purpose of this thesis is to study the degrees of the Kummer extensions relative to A,K and G.

In the MSc Chemistry programme you will focus your studies on one of LIC's two main research areas, Chemistry for Health or Chemistry for Sustainability, and one specialisation.

How do young people pursue their interests in and across multiple contexts while participating in tailor-made programs in vocational education and training (VET) and social enterprises to regain perspective in school and work?

Central to the MSc education is the research training project, which is the most important educational element of the programme. In the research training project, the student becomes a part of a research group for at least five months and learns not just specific practical skills, but also grows into…

There are multiple movable whiteboards which allow group working in various sizes. Windows and tables are additional writing surfaces. There is also…

This thesis consists of three chapters, the first two of which concern division points of elements of the multiplicative group of a number field.

How are interests embedded and experienced in daily life and to what extent can their origin and development be understood in terms of this contextualization?

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.

The aim of this project is to develop accurate but interpretable ensemble learning methods for high-dimensional multi-domain data.

How can wide-scale applications of isotope analyses and isotope mapping contribute to the identification of ancient migrants and their origins in the Western Caribbean? Can we observe linkages between individual behaviors and long-term patterns, for example as manifested in continuous waves of migration?…

The research group Science Communication and Society has been physically within the Institute of Biology (IBL) since 2012 and has become a formal part of the institute in 2018.
