Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

We have to do all we can to stop climate change. But: the Earth is more resilient than we thought. That is the surprising conclusion of an international team of ecologists and mathematicians, which included Leiden mathematician Arjen Doelman. The team discovered that ecosystems can still avoid tipping…

Imagine scanning lion dung or a mouse dropping and instantly knowing exactly what and how much the animal has eaten. Thanks to new DNA techniques, this is becoming increasingly feasible. PhD student Kevin Groen tested how effective these techniques are at unraveling the diets of wild animals.

Fantastic plants, dizzying patterns and pulsating sounds: researchers from Leiden are going to study the effects of a simulated psychedelic trip on the mind and body at Lowlands Festival. Why might this be interesting for therapies?

Connecting scientific fields, enhancing research and teaching, and providing innovative solutions to complex social issues: that is the idea behind interdisciplinary research. What did the university achieve in 2024? A small sample.

Using biomethane to produce ammonia, a crucial chemical in agriculture, could drastically reduce the climate impact of the process. In a study published in One Earth, researcher Robert Istrate shows it’s even possible to make ammonia production net-zero or carbon negative.

Hortus prefect Paul Keßler was a part of the delegation of Leiden researchers that traveled to Indonesia on a knowledge mission. In two weeks, he visited seven different universities and institutes and of course he also went to see three botanical gardens.

Foreign investments in the Dutch East Indies during the colonial period could have been of more benefit to the Indonesian economy.
