With the holidays just around the corner in this dark month of December, when we light candles as a symbol of warmth and hope, we would like to take a moment to reflect on this past year. We have accomplished a great deal together but the year has been difficult at times.

The steady decline in lethal gun violence in the EU came to halt in 2012 and some countries, such as Sweden, have even noticed an increase since then.

With the help of the JEDI fund, Fatima al Moufridji and Thijs Porck went in search of cultural contacts between early medieval England, Northern Africa, and the Middle East. Together they made four knowledge clips that can now be seen on YouTube.

Fish populations in lakes and rivers have declined in recent decades. This is probably due to light and noise pollution. The Horizon Europe grant enables ecologist Hans Slabbekoorn to investigate this and improve the situation for migrating fish. In order to do so, a seven-metre-long swimming tunnel…

Within the same species of butterfly many different wing patterns can occur. How is this possible? According to researchers Ben Wielstra and Emma Berdan, of the Institute of Biology Leiden (IBL), the answer lies within supergenes. A supergene is a part of a chromosome that contains many strongly linked…

Leiden artist Jos Agasi gets to create the artwork for the atrium of the new Gorlaeus Building. His work was chosen from several entries and will be a real eye-catcher in the building. The artist has a fascination for light and uses it to create works of art with all kinds of materials, objects and…

A bacterium hiding from the immune system and picking up bits of DNA from its environment. The result: gaining new traits, such as better protection against antibiotics. Fortunately, we have not found such a damning scenario yet. However, PhD student Renée Kapteijn did find the first clues, which…

Luca Giomi has the first results of his ERC consolidator grant. He discovered that epithelial cells move collectively but in different ways, depending on the scale you look at. It is hexatic at small scales, and becomes nematic at larger scales: it is a multiscale order. This collective movement of…

Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.

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.

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…

As early as 2030, batteries in electric vehicles could fully meet the need for short-term electricity storage around the world. By connecting them to the power grid they can provide their stored energy, improving energy security and enabling renewable technologies in cleaning the grid.

Jasper Knoester is the dean of the Faculty of Science. How is he doing? What kinds of things is he doing and what does his day look like? In each newsletter Jasper gives a peek into his life as dean.

From memorials to the armed forces to memory stones for individual victims. It was only later that the Holocaust took a central role in Western remembrance culture, Cleveringa Professor Frank van Vree notes. ‘Nationalists and human rights activists both invoke the experience of the Holocaust.’

From 1 October onwards, Dennis Claessen and Marcel Schaaf will be the new directors of education of Biology. They will replace Han de Winde. Schaaf will be responsible for the bachelor, while Claessen will mainly focus on the master tracks of Biology. We gave students and the education office the change…

For over a year now, the James Webb Telescope has been sending stunning images that exceed astronomers’ expectations. The photos are fascinating to see, but what exactly are we looking at? Assistant professor Melissa McClure explains.

The brightness peak of the ring around M87's supermassive black hole has shifted 30 degrees counterclockwise in a year. This is shown by new images released by the Event Horizon Telescope consortium.

So much has happened this year! 2023 was an eventful year in which several wars raged about which our experts could offer interpretation.
