Leiden professor of Environmental…

It is important for social animals to be able to recognise one another quickly. Humans are able to recognise each other immediately from their faces. Faces are also important for chimpanzees, but a new study by neuropsychologist Mariska Kret in PLOS ONE shows that the animals' buttocks also play a…

For the first time, astronomers have observed in three dimensions that gas from spiral galaxies is blown upwards and downwards at high speed, far out of the galaxy. They thereby confirm the theory of galaxy evolution: that star-forming galaxies create intergalactic gas flows by discharging gas along…

IBL-researchers revealed in a new study that insects are successful on land because their eggs became protected against desiccation. An extraembryonic membrane in the egg, the serosa, helped insects to make the transition from water to land.

How to contribute to Inter-Section? What does the process look like? We have answered the most frequently asked questions.

“Music is about everything else,” theater director Peter Sellars said upon accepting his Polar Music Prize back in 2014. Although it is about particular musical problems, Stanimiras dissertation is about ‘everything else’, too. What and how that is, could be summed up in different ways depending on…

Quantum computers deserve their own quantum internet. This is a network that dispatches information not in the form of bits - ones and zeros - but rather as qubits, just like in the quantum computer itself. In the view of Dirk Bouwmeester, a professor in Leiden’s Quantum Matter & Optics research group,…

Bordering Up: Regulating Mobility Through Passes, Walls and Guards

At the heart of this study is a thorough inquiry of categorisations of social identity used in the VOC’s record-keeping bureaucracy. How were service, occupational and caste groups classified and shaped by the VOC?
