Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

Researchers from Leiden University Medical Center (LUMC) have discovered how malaria parasites escape the immune system of mosquitoes. The so-called QC enzyme changes proteins on the outside of the malaria parasite such that the immune cells are unable to recognise the parasite. As a result, the parasite…

This is the Board of Advisors of CompaRe.

This week we can vote in the University elections. The University Council and faculty councils are incredibly important. During the fantastic seminar on 50 years of participation that the University Council recently held, our former Rector Carel Stolker aptly said: ‘Without participation, there would…

Schistosomiasis is an acute and chronic disease caused by blood dwelling parasitic trematodes of the genus Schistosoma, and it is classified as the second most socioeconomically devastating parasitic disease, second only to malaria.

Leiden University’s President of the Executive Board, Professor Annetje Ottow, has been reappointed for a second term by the Board of Governors.

Parasitic worms and stomach bacteria suppress immune reactions such as allergic responses. Parasitologist Hermelijn Smits and lung specialist Christian Taube from the LUMC are trying to learn from these micro-organisms.

Leiden University has a new Executive Board. Since 8 February 2021, Annetje Ottow has been the new President and Hester Bijl the new Rector Magnificus of the Board, while Martijn Ridderbos has continued in his role as Vice-Chairman.

ChatGPT, the text-generating chatbot, has recently become available for anyone to use. Is this artificial intelligence (AI) tool a threat to our teaching?

The infectious diseases malaria and tuberculosis are responsible for 2.1 million deaths every year. Leiden researchers are currently testing a new tuberculosis vaccine.

This is a difficult time. Above all, for all those directly involved in this horrible case – unacceptable behaviour by a professor and his removal from the University – the case we went public about on 18 October and that has been reported in the media. This is painful and tough for the complainants…

If we need funding for a project, equipment or research at the university, we automatically think of the Dutch Research Council or other grant providers. But more and more researchers are managing to connect with people who care about the university.

Several Dutch universities have said they do not want foreign student numbers to grow any more in some of their degree programmes. They are reaching maximum capacity. We are also alert to this in Leiden, but I see many positive aspects to the intake of international students.

We asked a lot of everyone last year. The Personnel Monitor showed that the workload was high in 2022 and Covid took its toll. I therefore think everyone deserves some downtime. Time away from the daily grind.

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

Even embryos can become embroiled in an evolutionary arms race with another species. Leiden biologists demonstrate this with larvae of the rosy bitterling that parasitize the gills of freshwater mussels. They published their research on February 19 in PNAS.

The Executive Board has appointed Mette Kamerich as the assessor and student member of the Faculty Board of the Faculty of Humanities. The appointment is for the period from 1 September 2025 to 1 September 2026, and she will therefore succeed Nova Verkerk in this role.

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…

I was disgusted by the recent Ongehoord Nederland broadcast on 15 September. The racist and hateful comments made by alumna Raisa Blommesteijn were, as far as I am concerned, way over the line and in my opinion also violate Article 1 of the Constitution of the Netherlands.

The more than 370 sensors that have been hung up in Leiden University buildings to count the people present will not be switched on again. The equipment will eventually be removed from the buildings.

Now the introduction weeks can go ahead as usual, the new students’ enthusiasm is overwhelming. It’s back to normal for the student associations too, having had a hard time of it during the pandemic.

Leiden University is a fantastic example of a network university: we create an impact with the city, stakeholders and regional and international partners. The lines of communication are really short and there is a great sense of togetherness. Our good relations with the city have also informed how we…

I recently went to the anniversary celebration of The Meeting Point, and the stories the refugee students told made a huge impression on me. The Meeting Point helps students from different backgrounds feel part of our university community.

Ever since its foundation, Leiden University has turned its gaze outwards to other cultures, languages and forms of academic practice. It is only natural, therefore, that we as a university have four institutes abroad: the Royal Netherlands Institute of Southeast Asian and Caribbean Studies (KITLV-KNAW)…

Our immune system protects us against disease, but every now and then, something goes wrong: an enemy invades our bodies or our immune system attacks our own cells and we become ill. Doctors and researchers at the Leiden University Medical Center (LUMC) want to be able to manipulate the immune system…

A lot is going on in the world right now, and our university regularly faces big issues and dilemmas too. Then it can be tricky to switch off. For me, exercise is a way to unwind. We want our staff to be able to relax too and are therefore offering various events and workshops that should help.
