Keti Koti in Leiden: 'Here, too, slavery is all around us‘
Many traces of the city's slavery history can be found in Leiden but the public isn't always aware of them. The initiators of 'Mapping Slavery in Leiden' want to change this with guided tours and street markers. Representatives of the University and other Leiden institutions will be giving the first…

The magic of liquid helium: this person makes ice-cold research in Leiden possible
White clouds of ice-cold gas flowing across the floor. Magical, but be careful not to freeze your fingers off. We are of course talking about liquid nitrogen and helium. You may have seen the spectacular Freezing Physics science show by the student organisation Rino. But did you know that this commodity…

Extraordinary treasures on National Finds Day
Is it a prehistoric mammoth tooth or just an ordinary pebble? It was National Finds Day at the Dutch National Museum of Antiquities on Saturday 17 June, and Leiden University was one of the collaborating partners.

Lowlands as lab: virtual trips in the name of science
While tens of thousands of visitors dance to deafening music, a team of Leiden psychologists are trying to collect data for their research at Lowlands. How do festivalgoers experience a virtual trip? And what role do factors such as too little sleep and whether they have experience with psychedelics…

Assessing total environmental impact is becoming even more important
Life cycle assessment (LCA) reveals the total environmental impact of products or production processes, and EU rules are going to make this even more important.

‘Ask scientists how to build the circular economy’
Some governments and companies are pursuing a more circular economy, but what is the best way to get there? An international group of industrial ecology researchers wrote a report that stresses the importance of including the scientific side into policies and practices. ‘We feel an obligation to support…

Hoard of Roman coins turns out to be offering for safe crossing
Several years ago, two amateur archaeologists from Brabant discovered over a hundred Roman coins near to Berlicum in the north of the province. After years of research, it now appears that the location, close to a ford in the river, was a site for offerings. Another interesting fact is that the coins…

Four Leiden Scientists: 'Environmental risks of new pesticides with nanoparticles insufficiently examined'
The environmental risks of new pesticides containing nanoparticles are inadequately researched, according to four Leiden scientists in the scientific journal Environmental Science & Technology. They call for an examination of the long-term and environmental effects of pesticides containing nanoparti…

Tunnel vision alarm in the search for more efficient hydrogen cells
A tenacious postdoc researcher persuaded Professor Marc Koper to research the oxygen reduction reaction. In Koper's eyes, there was little of interest there. But they promptly discovered a whole new way to improve fuel cells on hydrogen and oxygen. Their article appeared in Nature Catalysis on 07 Ju…

The quest for the magic angle
Stack two layers of graphene, twisted at slightly different angles to each other, and the material spontaneously becomes a superconductor. Science still can't explain how something so magical can happen, but physicists use special equipment to reveal what is taking place under the surface.

Report: Tracking down green spaces in The Hague in places you don't always want to be
Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

Back to the scanner: brain science in times of corona
For their research many neuropsychologists use the brain scanners at the LUMC. At the start of the pandemic, the rules for visiting the hospital became stricter and a large amount of psychology research looked as though it would fall through. Thanks to good protocols the researchers can now pick up…
