During the spring of 2021, a group of eight biology students from Leiden set out into the dunes in search of amphibians. Using DNA, they determined the geographic origin of the animals.

Exotic marsh frogs from distant lands are colonising the south-east of the Netherlands. This has been demonstrated by biology students from our faculty. Although the amphibians thrive in our little country, they are harmful to native biodiversity.

For thirty years, the Dutch Newspaper AD conducted an annual search for the best herring. This came to an end when economist Ben Vollaard, based on a statistical analysis, claimed it was rigged.

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…

Minerva, which calls itself the oldest student association of the Netherlands, has the reputation of being an impenetrable bastion. A lustrum exhibition shows the turbulent history and points to a diversity of contacts: from close bonds with Leiden ‘coffee ladies’ to the visit of Sir Winston Churchi…

The field of leadership suffers from ‘adjectivism’, says Professor Ben Kuipers. He immediately caveats this by saying that he too is going furnish the word leadership with an adjective: ‘Public’. But the goal here is to view leadership in a different light in his new role as Professor of Public Lead…
