How do we define the works of a film director whose films cross many established boundaries at once?

Nicotinamide adenine dinucleotide (NAD+) is the substrate used for the introduction of the ubiquitous and highly dynamic PTM in which either one or multiple adenosine diphosphate ribose (ADPr) moieties are covalently attached to a nucleophilic side chain of an specific amino acid in the target protein…

We perform multidisciplinary research at molecular, cellular, and organismal levels of animal biology to increase fundamental understanding of health and disease.

In her capacity as a lawyer and expert in International Humanitarian Law and Human Rights, Professor Helen Duffy is filing a lawsuit against the Dutch State. Leiden University’s weekly newspaper Mare reports that through her role, Duffy is assisting a Palestinian Dutchman whose family was killed in…

The research programme Statistical Science is concerned with the analysis and interpretation of masses of data, the quantification of uncertainty using probability models, and the development and benchmarking of algorithms and methods with these aims.

This NWO-funded research programme focuses on the assumptions and methodology of the writing of history of science. History of science is in many respects a flourishing discipline: it currently yields an impressive volume of studies. Systematic reflection about the ways in which history of science may…

Solar energy is used by photosynthetic organisms to drive energy required cellular processes. Is absorbed by two groups of pigments, located in the LHCs.

Project TARGET aims to improve our understanding of gun violence in Europe and the relationship between gun violence and firearms trafficking.

The aim of this study is to further develop the Open Science Monitor, which started as a pilot study.

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

The research described in this thesis combines the latest insights in lysosomal function with lysosome centred cell signalling.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

At Leiden University, we see open Science as the way to make a greater scientific and societal impact. There is also great momentum across the Netherlands for open science, and for good reason.

Citizen science is an umbrella term. It describes a range of ways to involve citizens and societal actors such as NGOs in collaborative knowledge production: crowdsourcing research questions, collective data gathering and analysis (to name a few examples).
