On 15 April, our much-beloved and highly respected former colleague Dr Hans Brussee passed away from cancer. In January 2025, Hans began experiencing neck pain. Initially, it appeared to be a herniated disc, but sadly, the diagnosis was soon revised, and his condition proved untreatable. Hans was 77…

Leiden University Medical Center (LUMC) has spent the past five years coordinating an international study of genetic mutations and breast cancer risks. The results will make it easier to determine which genes increase the risk of breast cancer and to what extent. The researchers published their results…

The use of fire can tell us a lot about human evolution. Archaeologist Femke Reidsma has developed a more accurate technique to identify how our ancestors used fire. Existing archaeological studies will need to be revised. Reidsma’s study was published in Nature Scientific Reports on 2 November.

After the lockdown, it was again possible to receive graduates and guests at the University. In recent weeks, BSc and MSc graduates from various study programmes were festively awarded their diplomas in a special corona-proof setting in the restaurant of the Gorlaeus Lecture Halls building. This resulted…

Leiden professor of molecular astrophysics and astrochemistry Ewine van Dishoeck was presented with the Niels Bohr International Gold Medal on Friday 7 October. The medal, instigated by the Danish Society of Engineers IDA, was awarded by Queen Margrethe of Denmark at a ceremony at the Carlsberg Academy…

The rising energy prices cannot have escaped anyone’s notice. They have dominated the news in recent months. As a university, we too face a big challenge as the prices continue to rise. We will all have to do our bit in the coming months, also in view of the climate crisis that we want to help resol…

While health data is essential for scientific research, that data also needs to be protected. In her doctoral thesis, Irith Kist found a balance between protecting the individual and exchanging health data.

Researchers from the Leiden University Medical Center (LUMC) have successfully used stem cell gene therapy to treat a baby with the severe congenital immune disorder SCID. An important milestone: it is the first time stem cell gene therapy of Dutch origin has been administered to a patient, and also…

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.
