She narrowly defied bureaucracy and spent days angling for cod. In the North Sea, marine biologist Inge van der Knaap discovered that noise significantly disturbs fish behaviour. ‘There is now a lot of attention for underwater noise.’

PhD student and research journalist Sebastiaan Grosscurt won a Tegel in May. In the data category, Grosscurt and his colleagues won the prestigious Dutch journalism award. 'For me, ecological research and journalism are two ways of achieving the same thing.'

Fish populations in lakes and rivers have declined in recent decades. This is probably due to light and noise pollution. The Horizon Europe grant enables ecologist Hans Slabbekoorn to investigate this and improve the situation for migrating fish. In order to do so, a seven-metre-long swimming tunnel…

All students in the Netherlands are invited to take part in the National Student Survey (NSE) once a year. Via the NSE you can give your opinion on the positive aspects of your study programme, as well as what you think could or should be improved.

Autism spectrum disorder, or ASD, is the term for a range of neurodevelopmental conditions or differences which can impact your studies at Leiden University.

AD(H)D stands for Attention Deficit(-Hyperactivity) Disorder, which is a common disorder that can impact your learning at Leiden University.

Underwater noise from seismic surveys affects the behaviour of Atlantic cod. These are the results of research by Leiden biologists in collaboration with colleagues from Belgium. During such surveys the fish are less active than usual and their circadian rhythm is disrupted; soon after exposure they…

I think we should go this way. This way! THIS! WAY!! Making yourself heard in a city can be difficult. That is not only the case for humans, but birds seem to be hindered by urban noise as well. Researcher Hans Slabbekoorn of Leiden University already showed that great tits in Leiden communicate differently…

When designing public spaces, noise is often a neglected issue. Architects and urban planners know little about it; noise experts see it mainly as a problem that should be solved simply by reducing the volume. University lecturer Andrea Giolai (LIAS), researcher Kevin Toksöz Fairbairn (ACPA) and Professor…

Hans Slabbekoorn is specialised in animal sounds. On 1 July, he was appointed professor of Acoustic ecology and behaviour. A great honour, according to the new professor. ‘This job never gets boring, whether I am investigating the urban jungle or marine noise.’

The starting point of human-induced landscape changes has been under permanent debate. It is widely accepted that the emergence of agriculture strongly increased human impact on their environments. However, foragers can and do actively transform land cover and ecosystems. Ethnographic observations,…

No more smelly lorries disposing of building waste or delivering building materials to the centre of Leiden. That’s Leiden University’s ambition for its future renovation or construction projects in the city centre. Electric boats should make the process cleaner and less inconvenient for the people…

Over the next few years, the Pieter de la Court building will be refurbished. This summer, the first to be tackled is the basement. What will happen?

Is aggression always bad? PhD research by psychologist Simone Dobbelaar shows that it is not. In fact, children who occasionally fiercely defend themselves and stand up for their peers often feel better mentally.

Physicist Milan Allan will build an instrument that will bring superconductivity research further. He has been awarded an ERC Consolidator Grant of 2 million euros over the next five years. With his PairNoise programme he aims to detect paired electrons as they occur just above the temperature at which…

Jianfeng Ge and Milan Allen of Leiden University look for majorana quasiparticles using shot noise measurements

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

Cultural anthropologist Sabine Luning, cultural historian Paul van de Laar and professor of architecture and urban development history Carola Hein say that the things that are not shown in images are also worth studying.

The bachelor's programme in International Studies is celebrating its tenth anniversary. Ko Voskuilen was among the very first batch of students to follow the study, and Sophia Healy graduated this summer. How do they look back on their time at the university?

50 years ago Lauterbur published the basic principle of MRI. Sine then MRI has become more expensive. Professor Andrew Webb describes what is needed to make MRI available for everybody.

While tens of thousands of visitors dance to deafening music, a team of Leiden psychologists are trying to collect data for their research at Lowlands. How do festivalgoers experience a virtual trip? And what role do factors such as too little sleep and whether they have experience with psychedelics…
