Our earliest ancestors in Africa already cracked open bones to extract the fatty marrow from bone cavities. But now a new study published in Science Advances demonstrates that our…

A consortium led by Leiden University has been awarded 6.75 million euros to research traumascapes: physical places associated with collective trauma and loss. The research team aims to make these places more visible, accessible and inclusive.

How do you compare the living environment of Dutch dairy cows with that of Masai cattle in East Africa? And how can we reverse biodiversity loss? These questions are central to CurveBend, an international research consortium in which ecologist Michiel Veldhuis plays a key role.

It is late June, and on a windy meadow north of Leiden known as the Vrouw Vennepolder a group of archaeology students just hit the last ice age. Considering this involves manually pushing a ground core to a depth of 10 meters, this is no small feat. Even so, the taking of ground samples in this, at…

Imagine no one in the Netherlands would eat animal products anymore, what would happen? And would it contribute to more climate justice? That is the theoretical exercise that environmental scientist Jan Willem Erisman and landscape architect Berno Strootman are taking up. 'Sometimes you have to think…

We invite proposals for the conference entitled ‘Ruins and Memory in the Muslim World: Typologies and Motifs (622-1800 CE)’ to be held in Leiden between 14-16 September 2026.

Does a communal garden provide cool air and warm neighbourly relations? Does an additional row of trees increase biodiversity? These kinds of questions are key in the COMBINED project, on which Leiden scientists and residents of The Hague, among others, can work for six years with 4 million euros from…

What do bats do at night when they’re not hunting? Using tiny GPS trackers, Leiden researchers discovered that pond bats spend a substantial portion of the night resting – often outdoors. This surprising insight could change the way we protect them.

In June 2024 the Faculty of Archaeology welcomed a new Assistant Professor.

The plane trees from the forecourt of Cluster North have been moved to the Herta Mohr building (Cluster South). The trees could not remain in their original location because of the forthcoming renovation of Cluster North. They have been moved already in advance of the flowering season. In June, the…

Lions in Kenya respond very differently to human land use, climate and conservation practices. That is the conclusion of thesis from Leiden biologist Monica Chege. A uniform approach is therefore insufficient. ‘Effective conservation only works when management is tailored to local conditions and developed…

Hunter-gatherers caused ecosystems to change 125,000 years ago. These are the findings of an interdisciplinary study by archaeologists from Leiden University in collaboration with other researchers. Neanderthals used fire to keep the landscape open and thus had a big impact on their local environment.…

Fossil teeth can preserve remarkable information, much like a biological identity card with data about the lives of individuals tens of thousands of years ago. By analyzing teeth, a new study published in Science Advances reconstructed the life history of four straight-tusked elephants (Palaeoloxodon…
