How light and noise pollution disrupt aquatic life
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…

How polluting buildings and machinery make rich countries ever richer
Rich countries are getting richer because of environmentally polluting (construction) investments from the past, largely at the expense of poor countries. This was shown by long-term economic and environmental data. 'The gap between poor and rich countries is widening.' Scientists from the Leiden Institute…

How polluting are the clothes in your closet?
Cotton is the most widely used natural fibre for clothes. But how polluting are our jeans and shirts actually? Environmental scientist Laura Scherer coordinated an international research project on the impacts of cotton. ‘The purchases of consumers in Europe can contribute to water scarcity in China…

New technology could make hard-to-recycle plastics recyclable
Cookware handles, electrical plugs, brake pads. Unlike other plastics, these ‘thermosets’ cannot simply be melted down and reshaped, making them difficult to recycle. Chemist Roxanne Kieltyka and her team are now exploring a way to make these materials recyclable, potentially transforming the way we…

'One in five bacteria we tested were capable of breaking down plastic'
Leiden PhD candidate Jo-Anne Verschoor discovered that nearly twenty percent of the bacterial strains she studied could degrade plastic, though they needed some encouragement to do so. ‘Bacteria are just like people,’ says Verschoor. Her research was published in the journal Communications Biology,…

From Steno to Snickers: the Anthropocene through the eyes of a coot
What looked like an ordinary coot’s nest turned out to be a five-star location with a remarkable backstory. Beneath a jetty on the Rokin in Amsterdam, biologist Auke-Florian Hiemstra discovered a true time capsule — complete with face masks from the COVID era and a Mars wrapper dating back to the 1994…

The lifecycle of a cigarette filter
The university is launching a campaign to focus extra attention on our smoke-free university locations. The University is using aptly named cigarette barrels to try to show clearly just how many cigarette filters are being saved from the environment. How harmful are these cigarette filters to the e…

Working together on the plastic problem: how to keep citizens engaged?
What motivates citizens to participate in a citizen science project on plastic pollution? And does that motivation change over time? Liselotte Rambonnet tried to answer these and other questions with her research on the Clean Rivers (‘Schone Rivieren’) project. Rambonnet is a PhD student at the Institute…

Kilotonnes of 'recycled' Dutch plastic waste end up in the sea
On paper it is recycled, but in reality enormous quantities of plastic waste from the Netherlands end up in Asian seas. Researchers from the Leiden Institute of Environmental Sciences charted the fate of plastic food packaging waste from the Netherlands. They published their results on July 8 in the…

Lights off, sound on: Leiden University opens artificial river to study fish migration
On 16 June, Leiden University opens the MIGRADROME: a unique, seven-metre-long artificial river. Researchers will use it to study how light and sound affect migratory fish. ‘We’re recreating a real river, but under fully controlled conditions.’

It is not easy to simplify your research
Defending your PhD research in front of nearly 300 elementary school students: that was the challenge faced by PhD candidates Jo-Anne Verschoor and Marinka de Willigen during the VUURVLIEGEN competition organised by the Centrum JongerenCommunicatie Chemie (C3). After an exciting competition, the children…

Smart data for sustainable agriculture: less hassle, more green
In supermarkets, consumers are drowning in a sea of sustainability labels. Confusing for them, but also farmers can't see the forest for the trees. Obtaining these labels demands an enormous amount of time and effort. Berent Baris is investigating ways to simplify this process, benefiting both farmers…

Lights out, stars on: Daan Roosegaarde on Seeing Stars Leiden
‘What if we switch off all the lights one evening? That idea crossed my mind from time to time. And when I mentioned it to a taxi driver one day, he said: “Oh, you mean: lights out, stars on!” That’s not completely true, of course, because the stars are always on, but his phrase summed up the idea n…

18 billion animals a year: they die, but never end up on our plate
Each year a staggering 18 billion chickens, turkeys, pigs, sheep, goats, and cows either die or are killed without making it onto someone's plate. Environmental scientists Juliane Klaura, Laura Scherer, and Gerard Breeman were the first to calculate this number on a global scale. 'Reducing these numbers…

Cod behave differently in noisy environment
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…
