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.

Health conditions and social problems often go hand in hand. To address this complex issue in families in The Hague, researchers, managers, support services, policymakers and residents are joining forces. What are the results of this transdisciplinary approach?

Of the 900 new companies that have set up shop on the Netherlands’ largest campuses since 2018, 194 chose Leiden. This makes the Leiden Innovation District the fastest growing of the larger campuses. This is the conclusion a study by Buck Consultants International.

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…

Sunshine, ice cream, coffee, and plenty of good vibes. Once again, students and staff made the most of the We are Science Week. Relive some of the highlights with our photo report!

A European team of astronomers has discovered the largest stellar black hole in the Milky Way. It is more than thirty times as massive as our sun and is located in the constellation of Aquila, about two thousand light-years from Earth. The astronomers stumbled upon the black hole by chance while preparing…

On 22 May, astronaut André Kuipers opened the new Mediterranean garden in the Hortus. With this water-efficient garden, the Hortus aims to offer inspiration for future- and climate-proof garden planting. Prefect Paul Keßler and scientific director of the Leiden Observatory Ignas Snellen also signed…

Not only dark matter, but also ordinary matter and dark energy are tracked in the largest ever cosmological computer simulation ever. In the FLAMINGO simulations, you can see virtual galaxies and clusters of galaxies emerging over the course of billions of years. This is no easy task: with more than…

Most young alumni who graduated during the COVID-19 pandemic did not get a graduation ceremony, nor did they have the chance to sign their name in the Sweat Room. Thanks to the Alumni Office, they now have the chance to do so after all.

Astronomers at Leiden University have detected rare isotopes of carbon and oxygen in our neighbouring stars for the first time, providing a new window to better understand the chemical evolution of the cosmos.The results are published today in the journal Nature Astronomy.

Can a robot help prepare cancer medication in a hospital pharmacy? That’s what hospital pharmacist Tjerk Geersing investigated in his PhD research. He compared manual and automated preparations in terms of quality, efficiency, and safety. He graduated on 19 March.

Leiden artist Jos Agasi gets to create the artwork for the atrium of the new Gorlaeus Building. His work was chosen from several entries and will be a real eye-catcher in the building. The artist has a fascination for light and uses it to create works of art with all kinds of materials, objects and…

Nanomaterials can pass much further along the food chain than was previously thought. The particles can change shape and size in each organism, enabling them to pass on to the next one in the chain. Researchers from the Institute of Environmental Sciences discovered this accidentally when using a novel…

Diversity and inclusion are core values for Leiden University, and our aim is to offer all staff and students equal opportunities. As the University lacks adequate information about the cultural diversity of our staff, this spring we are taking part for the first time in the Cultural Diversity Barometer.…

An international team led by astronomers at Leiden University has shown in laboratory experiments that sulfur can bind with ammonium under icy cosmic conditions and form a salt that sticks to dust and pebbles. The resulting sulfur salt not only helps to explain the mystery of the missing sulfur gas,…

Each year on the university’s birthday, children at primary schools in Leiden and The Hague have a lesson from a professor – about children’s rights and robots in surgery, for example. The children get to do activities. And ask questions: ‘How do you become a professor?’
