Two students from the Leiden-Delft MSc Industrial Ecology programme have made a carbon footprint calculator for the website www.doemaarduurzaam.nl; the website where the Dutch public broadcasting organisations collect everything broadcasted about sustainability. The carbon footprint calculator allows…

The newly launched NWO funded research project ‘Bridging art, design and technology through Critical Making’ aims to interrogate Critical Making by experimentally applying it to a broad range of artistic practices.

Arjan Louwen (MA) will start a PhD research project on the social and ideological aspects of Late Bronze Age and Early Iron Age cremation graves in continental Northwest Europe (1100-500 BC): Breaking and making the ancestors. Making sense of the inconspicuous 99% of urnfield graves.

Every year the international leadership course of the Leiden Honours Academy, the International Leiden Leadership Programme (ILLP), attracts master’s students from all over the world. In June, this year’s 25 students will get their certificates, but that is not the most important part, according to…

Governments have increasing amounts of data at their disposal. How can big data be used in policymaking? And are governments ready to deal with all this data? That is what Sarah Giest, Assistant Professor at the Institute of Public Administration, is interested in.

‘Statistics? I hated that hard subject in school’, statistician Sanne Willems is often told. And that is a pity, she thinks, because statistics doesn’t necessarily have to be difficult. Together with two former fellow students, she set up a Statistics Communication section for good communication on…

Through each individual decision, however small, people make history. This is what historian Katja Happe said in the Cleveringa Lecture on 26 November. She illustrated this with individual reactions to the persecution of Jews during the Second World War.

Despite the field’s general agreement that pyrotechnology had a significant impact on the cultural evolution of humankind, our understanding of the origins and development of fire use and its role in humankind’s cultural evolution is very limited, blurred by strong disagreements over its chronology…

Regular users of cannabis are less aware of their own mistakes, and they are not good at creative thinking. This is the conclusion drawn by psychologist Mikael Kowal from his research on the effects of cannabis. PhD defence 6 October.

One of the ambitions of the Learning@LeidenUniversity vision on teaching and learning is to foster an international and inclusive educational community in which everyone feels welcome, regardless of religion, sex, sexual orientation or cultural background. One student service that promotes inclusion…

Leiden University is working on sustainability and should give its efforts more publicity. This is the conclusion of Industrial Ecology master’s students who investigated the extent to which Leiden University is green and sustainable.

Embryonic stem cells have the remarkable ability to develop into any type of cell. On their way to become for example a liver or a heart cell, they must repeatedly decide between alternative developmental paths. How they make these decisions is largely unknown. An international team of biophysicists…

Its idyllic setting and white sandy beaches have made the Maldives a hotspot for tourists. This provides an income but is a problem for the fragile natural environment. Students from various universities worked with the local people to make the soil more fertile. How did they go about it?

An international team of astronomers, including Professor Koen Kuijken, has published a series of online articles presenting the first results of a major search for dark matter. Never before have researchers been able to chart so precisely the characteristics of groups of galaxies and their dark matter.…

A team of laboratory astrophysicists from Leiden University managed to make glycerol under conditions comparable to those in dark interstellar clouds. They allowed carbon monoxide ice to react with hydrogen atoms at minus 250 degrees Celsius. The researchers publish their findings in the Astrophysical…

Artificial intelligence systems are smart. They can recognize patterns better than humans, for example. Yet humans are still very much needed. How can you better steer those AI systems? LIACS lecturer Jan van Rijn wrote a book about this together with a number of colleagues. We asked him a few quest…

Over recent years Leiden University has taken some significant steps forward in innovation in teaching and learning and in diversity. But there is still a lot to be done. These were the comments by governors, lecturers and scholars during the farewell seminar for Vice-Rector Simone Buitendijk on 27…

Mapping out the problem of plastic pollution requires a lot of data over a large area. That's why scientists are increasingly turning to volunteers for help, also known as citizen science. But what are the challenges for a researcher when he or she involves the public in research in this way? Four Leiden…
