Using excavations, isotope analysis and cultural interpretations, he investigates how and why…

Long into the 19th century, seascapes were considered an expression of patriotism. Artists who painted in a 17th century style were valued more. This tradition stifled innovation in the genre, Cécile Bosman has concluded. She will defend her PhD thesis on 13 October.

‘Working in Leiden is a dream come true.’ Ákos Kovács studied in his birth country Hungary and worked in Germany, Denmark and Groningen. As professor of Microbiome Ecology at IBL, he immediately started working together with his new colleagues to make discoveries about the versatile bacterial species…

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…

It is late June, and on a windy meadow north of Leiden known as the Vrouw Vennepolder a group of archaeology students just hit the last ice age. Considering this involves manually pushing a ground core to a depth of 10 meters, this is no small feat. Even so, the taking of ground samples in this, at…

The discovery of a planet far too large for its sun defies models about the formation of solar systems and planets. In a paper in Science, researchers, including Yamila Miguel of Leiden Observatory, report the discovery of a planet more than 13 times heavier than Earth orbiting the ultracool dwarf star…

A unique multicenter study, including about 3,500 youth between 10 and 25 years old from across the globe, shows that artificial intelligence - specifically machine learning - is able to identify individuals with anxiety disorders based on their unique brain structure.

Understanding the behaviour of tiny droplets in our cells could aid the search for new treatments. A team of Leiden researchers has developed a groundbreaking method to study how these droplets transition from liquid to solid. This change plays a role in various diseases, including neurodegenerative…

Astronomers and surgeons from Leiden are collaborating with industry to develop an optical instrument that delivers faster, more accurate imaging of tumour tissue and abnormal blood flow during surgery.

Childhood trauma can have a lifelong effect. Many therapists do not dare to confront these vulnerable patients with their past because they are concerned that the patients will be unable to cope. Research has now shown that exposure therapy can be helpful for this group of people.

Roll-up solar panels, bendable phone displays, or better computer chips… The EU project STIBNITE investigated the next generation of semiconductors, made from organic materials based on carbon, nitrogen, and boron. The project has now concluded. During the Open Science Debate on 1 July, the group will…

Carola Hein, Professor of History of Architecture and Urban Planning TU Delft, has been affiliated with the Institute of Cultural Anthropology and Development Sociology of Leiden University since January 2022 as Professor Water, Ports, and Historic Cities. On the surface this may seem a strange combination,…

The city centre of Leiden is covered in them: wall poems. When roaming around, you come across poetry written in the Latin alphabet, but also in scripts that might be more difficult to understand for the average person living in Leiden. In a new series of videos, Tijmen Pronk talks more about this.

How do atoms and molecules end up forming planets? That's what astrochemist Julia Santos studied during her PhD. She discovered the dominant process behind the formation of methanol in space – a finding that surprised the entire field.
