That the new building of the Campus the Hague in the Wijnhaven is literally in the governmental heart of the Netherlands should not be a surprise. But who are our neighbors besides all the ministries and the municipality? Let’s take a little walk around the neighborhood.

This year the PhDs of the institute had their traditional day out (uitje) to The Hague. The last two years they had stayed in Leiden, so The Hague already seemed like quite the adventure. Indeed, it seems almost that as time progresses and more and more archives become digitized, history PhDs slowly…

A new study from Leiden researchers shows that the carbon emissions of building materials are set to grow if we do not act rapidly. Even with known interventions implemented in concert, these emissions are much larger than the remaining 1.5 degree budget for building materials at today’s share, the…

Yuvraj Birdja converted CO2 to formic acid to store energy in a sustainable way, with different catalysts. With this new knowledge, scientists are a step closer in industrially converting CO2 to chemicals and fuels. This can help reduce CO2 emission and the greenhouse effect.

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.

Foster children’s behaviour is more problematic than that of their peers in ‘normal’ family situations. However, it is difficult to determine the exact cause of behavioural problems. Anouk Goemans, a researcher in clinical child and adolescent studies, calls for more screening and monitoring. PhD defence…

Medicines are becoming increasingly precise and innovative, but at the same time increasingly expensive. With their innovations, it is up to universities to increase competition, thus causing prices to drop. This is what newly appointed Professor of Biomolecular Analysis Hubertus Irth argues. His inaugural…

On May 18 Janneke Wesseling gave a lecture at the conference

Leiden political scientists Yvonne Kleistra and Niels van Willigen have advised the United States State Department as to how to evaluate its foreign policy. Point of departure was a scientific model that Kleistra and Van Willigen have developed on the basis of their work for the Dutch Foreign Affairs…
