How do ideas concerning the academic study of religion relate to the socio-cultural and political context in which they are developed?

External PhD candidate Liselore Tissen (Leiden University/Delft University of Technology) has been blogging on the Faces of Science website since March about her daily work as a researcher. ‘Academia is anything but stuffy.’

Laura Nijkamp’s biggest dream came true recently: she took a parabolic flight and was weightless for a moment. The BrainFly student team, which includes psychology students from Leiden, needed volunteers. She signed up immediately. She tells us all about her experience.

In what way is constructivist logic able to account for both the role of the judging agent in inference and the universal claims of logical validity?

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.

Markus Davidsen, assistant professor of Religious Studies, is the winner of the 2021 Impact Prize. He is receiving the prize of 1,000 euros for the material he has developed for religious education in secondary schools.

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).

Leiden has been designated European City of Science 2022. The city's achievements as a city of science and innovation will be celebrated throughout the year, with as a highlight the international EuroScience Open Forum conference. The members of the core team that will organise this mega-event introduced…

The ability to collect and interpret huge quantities of data has become indispensable to society and academia. Leiden University is a knowledge and expertise centre for data science that places the emphasis on interdisciplinary collaboration and innovation.

From where litter ends up to which languages are spoken in Leiden and The Hague: over 50 interesting, surprising, complex and entertaining questions were sent in for the Citizen Science project to mark our 444th anniversary. Not one but two Citizen Science projects will be starting this year in Leiden…

Today, everybody and everything produces data. People produce large amounts of data in social networks and in commercial transactions. Medical, corporate, and government databases continue to grow. Sensors continue to get cheaper and are increasingly connected, creating an Internet of Things, and generating…

In the largest study of ancient DNA ever conducted, an international team of scientists has revealed the complex story behind one of the defining periods in European prehistory. The study is published this week in the journal Nature.

What is the influence of non-hereditary factors on our health, such as lifestyle, diet and exposure to harmful substances? The Exposome-Scan project, led by Leiden professor Thomas Hankemeier, has been awarded 3.2 million euros from the NWO Investment Grant Large programme to answer this question. With…

People who have negative expectations about a treatment actually experience more pain. Merve Karacaoglu discovered in her PhD research that anxious and pessimistic individuals are particularly susceptible to this nocebo effect. However, this sensitivity comes with a silver lining.

Citizen science has recently become a widely used term, but what does it mean exactly? How does citizen science compare to crowdsourcing? And where does community archaeology stand in this discussion?

The Faculty of Science has presented an infographic with tips and tricks for work stress. The reason for this was the Personnel Monitor 2018, which showed that work pressure is a problem for many employees at the Faculty. ‘It is important to start the discussion about work pressure, and to break the…

At the Institute of Political Science we value our alumni. We can learn from you, and would like to contribute to your further development. And, of course, we want to lend a hand in connecting ‘our’ political scientists all over the world.

The majority of scientists, from archaeologists through to zoologists, collect enormous volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics and computer science, we can develop algorithms for analyzing…

Research and design are becoming more and more important in international science education. In The Netherlands, two recently introduced subjects focus on research and design activities in the classroom: O&O (research and design) and NLT (nature, life and technology). This research aims to look at what…

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…
